Relations between the Greek and the Turkish states have been marked by alternating periods of mutual hostility and reconciliation ever since Greece won its independence from the Ottoman Empire in 1830. Since then, the two countries have faced each other in four major wars—the Greco-Turkish War (1897), the First Balkan War (1912-1913), the First World War (1914-1918), including the Greek genocide (1913-1922), and finally the Greco-Turkish War (1919–22), which were followed by the Greco-Turkish population exchange and a period of friendly relations in the 1930s and 1940s. Both countries entered NATO in 1952. Relations deteriorated again after the 1950s due to the 1955 Istanbul pogrom, the Cyprus issue, and the expulsion of the Istanbul Greeks in the 1960s, the 1974 Cypriot coup d'etat, immediately followed by the Turkish invasion of Cyprus in 1974, the Imia/Kardak military crisis in 1996 and subsequent military confrontations over the Aegean dispute. A period of relative normalization began after 1999 with the so-called "earthquake diplomacy", which notably led to a change in the previously firmly negative stance of the Greek government on the issue of the accession of Turkey to the European Union. As of 2021, military tensions have risen again due to conflicts over maritime zones in the Aegean and Eastern Mediterranean.

Byzantine against Seljuq and Ottoman
In 1048, conflicts between Seljuqs and Byzantines (Greeks were dominant nation of the Byzantine Empire and the Empire was Hellenized) started. Many wars and battles were fought between the Byzantine and the Seljuq armies. Also, in the 1300s, conflicts between Ottomans and Byzantines started.
In 1453, Ottomans conquered Constantinople, the capital city of the Byzantine Empire. In 1460, they conquered the Despotate of the Morea, in 1461 the Empire of Trebizond, in 1475 the Principality of Theodoro and by 1500 most of the plains and islands were in Ottoman hands. Holdouts included Rhodes, conquered in 1522, Cyprus in 1571, Crete, retained by the Venetians until 1669, and the Ionian islands which remained primarily under the rule of the Republic of Venice.
Ottoman era until 1820
During the Ottoman–Venetian Wars and the Russo-Turkish War (1768–74) Greece provided aid to Ottoman rivals. Dionysius the Philosopher additionally organised several uprisings. In addition, the Lambros Katsonis fleet began harassing the Ottoman fleet in the Aegean Sea.
In 1770, the Ottoman army invaded the Mani.
In the 1803, 1807 and 1815 the Ottoman army invaded Mani. Also during this period, in 1803 there was a final fight between the Souliotes and the local Ottoman ruler, Ali Pasha, which ended the many years of conflicts between them.
Ottoman era and the Greek state until 1913
In March 1821, the Greek War of Independence from the Ottoman Empire began. The Greeks formally declared their independence in January 1822, and after the Battle of Navarino in 1827, the establishment of a Greek state was recognized in the London Protocol of 1828. The first borders of the Greek state consisted of the Greek mainland south of a line from Arta to Volos plus Euboea and the Cyclades islands in the Aegean Sea. The rest of the Greek-speaking lands, including Crete, Cyprus and the rest of the Aegean islands, Epirus, Thessaly, Macedonia and Thrace, remained under Ottoman rule. Over one million Greeks also lived in what is now Turkey, mainly in the Aegean region of Asia Minor, especially around Smyrna, in the Pontus region on the Black Sea coast, in the Gallipoli peninsula, in Cappadocia, in Istanbul, in Imbros and in Tenedos.
Greek politicians of the 19th century were determined to include all these territories within a greatly enlarged single Greek state, based on the Byzantine model and with Constantinople (Istanbul) as its capital. This policy was called the Great Idea (Megali Idea). Constantinople had been the capital of the Eastern half of the Roman Empire until its fall to the Turks in 1453. The Ottomans naturally opposed these plans for a larger Greek state. The Empire was considered by the European powers as 'the sick man of Europe', but since these powers were irreconcilably divided over the fate of the Ottoman lands, the conflicts both reduced its territorial hold but also kept delaying its collapse.
During the Crimean War (1854 to 1856), Britain and France prevented Greece from attacking the Ottomans by occupying Piraeus. They were again prevented from taking military action during the Russo-Turkish War of 1877, in which the Greeks were keen to join in with the objective of territorial expansion, but Greece was unable to take any effective part in the war. Nevertheless, after the Congress of Berlin, in 1881 Greece was given most of Thessaly and part of Epirus. Also, in 1854–1896, there were revolts in the Ottoman Empire by the Greek population in Thessaly, Macedonia, Epirus.
In 1858–1896, there were many revolts in Crete, Thessaly Macedonia and Epirus against the Ottoman Empire by the Greek population.
In 1897, a new revolt in Crete led to the first Greco-Turkish War. An unprepared Greek army was unable to dislodge the Ottoman troops from their fortifications along the northern border, and with the resulting Ottoman counter-attack, the war resulted in minor territorial losses for Greece.
The Young Turks, who seized power in the Ottoman Empire in 1908, were Turkish nationalists whose objective was to create a strong, centrally governed state. The Christian minorities of the Empire, including Greeks, saw their position in the Empire deteriorate.
The First Balkan War of 1912–1913 was a direct consequence of the mounting tension, as a result of which Greece seized Crete, the islands, the rest of Thessaly and Epirus, and coastal Macedonia from the Ottomans, in alliance with Serbia and Bulgaria. Crete was once again the flashpoint for tension between the two nations.
The First World War and after (1914–1927)
Greece entered the First World War in 1917 with the intention of seizing Constantinople (Istanbul) and Smyrna (İzmir) from the Ottomans, with the encouragement of the British and French governments, who also promised the Greek government enosis with Cyprus at a certain stage. The ongoing genocide of Pontic Greeks in the Ottoman Empire also played a factor in this decision. Although there was little direct fighting between Greeks and Turks, when the Ottoman Empire collapsed in 1918 the Greeks were quick to claim the lands the Allies had promised them. The 1920 Treaty of Sèvres gave Greece eastern Thrace and an area of about 17,000 km2 in western Anatolia around Smyrna. This Treaty was signed by the Ottoman government but never went into force, not having been ratified by Parliament.
Greece occupied Smyrna/İzmir on 15 May 1919, while Mustafa Kemal Pasha (later Atatürk), who was to become the leader of the Turkish opposition to the Treaty of Sèvres, landed in Samsun on May 19, 1919, an action that is regarded as the beginning of the Turkish War of Independence. He united the protesting voices in Anatolia and set in motion a nationalist movement to repel the Allied armies that had occupied Turkey and establish new borders for a sovereign Turkish nation. Having created a separate government in Ankara, Kemal's government did not recognise the abortive Treaty of Sèvres and fought to have it revoked. The Greek advances into Anatolia were eventually checked and the Greek army was forced into retreat.
The Turkish army entered Smyrna/İzmir on 9 September 1922, effectively ending the Greco-Turkish War (1919-1922) in the field. The Greek army and administration had already left by sea. The war was put to an end by the Armistice of Mudanya, and the Treaty of Lausanne (1923) replaced previous treaties to constitute modern Turkey.
The Treaty of Lausanne (1923) also provided for a Population exchange between Greece and Turkey that had begun before the final signature of the treaty in July 1923. About one and a half million Greeks had to leave Turkey for Greece and about half a million Turks had to leave Greece for Turkey (note that the population exchange was on religious grounds, thus the exchange was officially that of Christians for Muslims). The exceptions to the population exchange were Istanbul (Constantinople) and the islands of Gökçeada (Imbros) and Bozcaada (Tenedos), where the Greek minority (including the Ecumenical Patriarch) was allowed to stay, and Western Thrace, whose Muslim minority was also allowed to stay.
Due to the defeat of the Greek army and the events following which terminated 3,000 years of Greek presence in Anatolia, Greece refers to it as the Asia Minor Catastrophe/Disaster. Greek accusations were focused on the Great Fire of Smyrna, especially in view of the account provided by George Horton, the U.S. Consul General in the city from 1919 to 1922. Horton's account remains as controversial as the fire itself.
The Treaty of Lausanne (1923) awarded the islands of Imbros and Tenedos to Turkey, under special provisions for the Greeks living there. Tenedos population was overwhelmingly Greek, and Imbros population was entirely Greek. However, after the legislation of "Civil Law" on 26 June 1927, the rights accorded to the Greek population of Imbros and Tenedos were revoked, in violation of the Lausanne Treaty. Thus, the island was demoted from an administrative district to a sub-district which resulted that the island was to be stripped of its local tribunals. Moreover, the members of the local council were obliged to have adequate knowledge of the Turkish language, which meant that the vast majority of the islanders were excluded. Furthermore, according to this law, the Turkish government retained the right to dissolve this council and in certain circumstances, to introduce police force and other officials who were non-islanders. This law also violated the educational rights of the local community and imposed an educational system similar to that followed by ordinary Turkish schools.
1928–1954: Normalization of the relations
The post-war leaders of Turkey and Greece, Kemal Atatürk and Eleftherios Venizelos respectively, were determined to establish normal relations between the two states. After years of negotiations, a treaty was concluded in 1930, and Venizelos made a successful visit to Istanbul and Ankara. Greece renounced all its claims over Turkish territory. This was followed by the Balkan Pact of 1934, in which Greece and Turkey joined Yugoslavia and Romania in a treaty of mutual assistance and settled outstanding issues (Bulgaria refused to join), embassies were constructed as a result. Both leaders, recognising the need for peace resulted in more friendly relations, with Venizelos even nominating Atatürk for the Nobel Peace Prize in 1934.
In 1941, Turkey was the first country to send humanitarian aid to Greece to relieve the great famine in Athens during the Axis occupation. Turkish president İsmet İnönü signed a decision to help the people whose army he had personally fought during the Turkish War of Independence 19 years earlier. Foodstuffs were collected by a nationwide campaign of Kızılay (Turkish Red Crescent) and sent to the port of İstanbul to be shipped to Greece. The aid was shipped on board the vessel SS Kurtuluş with big symbols of the Red Crescent painted on both sides.
At the same time, Turkey signed a "Treaty of Friendship and cooperation" with Nazi Germany to avoid invasion in June 1941. The following year, 1942, Turkey imposed the Varlık Vergisi, a special tax, which taxed the non-Muslim minorities of Turkey, including Greek minority. Also, during the WWII there was the incident of the Twenty Classes, this was the conscription of non-Muslims males who were sent in labour battalions.
The early Cold War brought closer the international policies of the two countries, in 1950 both fought at the Korean War at the side of the UN forces. In 1952, both countries joined NATO. In 1953 Greece, Turkey and Yugoslavia formed a new Balkan Pact for mutual defence against the Soviet Union.
Istanbul Pogrom, Cyprus crisis, Turkish invasion and the collapse of the Greek military junta (1955–1975)
A serious matter of conflict in Turkish-Greek relations since the 1950s has been Cyprus; at the time, it was a British colony with a Greek-Cypriot population share of 82%. Some of the Greek Cypriots wanted union (enosis) with Greece and, as early as 1931, there were nationalist riots in Nicosia. The Greek government, due to its financial and diplomatic dependence on Britain, demurred from officially expressing support for unification with Cyprus.
In the 1950s, the Cyprus issue flared up again when the Greek Cypriots, under Archbishop Makarios, claimed union with Greece, and the EOKA group launched a paramilitary movement on the island – primarily against the British administration, but also inflicting collateral damage to other parties and civilians. Eventually, Greek Prime Minister Alexander Papagos took the Cyprus issue to the United Nations.
Turkish nationalist sentiment, angered by the discrimination against the Turkish Cypriots, became inflamed at the idea that Cyprus would be ceded to Greece. This led to the Greek community of Istanbul becoming the target in the Istanbul Pogrom of 1955. In response, Greece withdrew from all co-operation with Turkey, which caused the Balkan Pact to collapse.
In 1960, a compromise solution to the Cyprus issue was agreed on: Britain granted independence to Cyprus, and a constitution was hammered out. Greek and Turkish troops were stationed on the island to protect their respective communities. Greek Prime Minister Constantine Karamanlis was the main architect of this plan, which led to an immediate improvement in relations with Turkey, particularly once Adnan Menderes was removed from power in Turkey.
During the period of intercommunal strife in 1963 and 1964, Greek and Turkish Cypriots were displaced and many were massacred on both sides.
On 30 December 1964, Makarios declared his proposal for a constitutional amendment that included 13 articles. Turkey, however, restated that she was against this and threatened war if Cyprus tried to achieve unity with Greece. In August, Turkish aircraft bombed Greek troops that surrounded a Turkish village (Erenkoy) and war seemed imminent. Once again, the Greek minority in Turkey suffered from the crisis, causing many Greeks to flee the country, and there were even threats to expel the Ecumenical Patriarch. Eventually, intervention by the United Nations led to another compromise solution.
In 1964 Turkish prime minister İsmet İnönü renounced the Greco-Turkish Treaty of Friendship of 1930 and took actions against the Greek minority. Turkey enforced strictly a long‐overlooked law barring Greek nationals from 30 professions and occupations, for example Greeks could not be doctors, nurses, architects, shoemakers, tailors, plumbers, cabaret singers, ironsmiths, cooks, tourist guides, etc. Many Greek have been ordered to give up their jobs after this law. 50,000 more Greeks were expelled. They were given a week to leave the country. Deportees protested that it was impossible to sell businesses or personal property in so short of a time. Most of those deported were born in Turkey and they had no particular place to go in Greece. Greeks had difficulty getting credit at banks. Those expelled, in some cases, could not dispose of their property before leaving. Also, Turkey forcefully closed the Prinkipo Greek Orthodox Orphanage, the Patriarchate's printing house and the Greek minority schools on the islands of Gökçeada/Imbros and Tenedos/Bozcaada. Furthermore, the farm property of the Greeks on the islands was taken away from its owners and university students organized boycotts against Greek shops. Teachers of schools maintained by the Greek minority complained of frequent “inspections” by squads of Turkish officers inquiring into matters of curriculum, texts and especially the use of the Greek language in teaching. In the same year the Turkish Foreign Minister, Feridun Cemal Erkin, in an interview appeared to imply that the Dodecanese closest to Turkey's Asia Minor coast should have been turned over to Turkey to preserve Greco‐Turkish friendship.
The Cyprus dispute weakened the Greek government of George Papandreou and triggered, in April 1967, a military coup in Greece. Under the diplomacy of the military regime, there were periodic crises with Turkey, which suspected that the Greek regime was planning a pro-unification coup in Cyprus.
A 1971 Turkish law nationalized religious high schools and closed the Halki seminary on Istanbul's Heybeli Island which had trained Greek Orthodox clergy since 1844.
On July 15, 1974, a band of Greek Cypriot nationalists formed EOKA B, advocating Enosis (Union) with Greece and, backed by the Greek military junta in Athens, staged a coup against the Cypriot President and Archbishop Makarios. An ex-EOKA man, Nikos Sampson was appointed president. On July 20, Turkey—using its guarantor status arising from the trilateral accords of the 1959–1960 Zürich and London Agreement—invaded Cyprus without any resistance from the British forces based on the island, occupied 37% of the northern part and expelled the Greek population. Once again, war between Greece and Turkey seemed imminent, but actual war was averted when Sampson's coup collapsed a few days later and Makarios returned to power. Also, the Greek military junta in Athens, which failed to confront the Turkish invasion, fell from power on 24 July. The damage to Turkish-Greek relations was done, and the occupation of Northern Cyprus by Turkish troops would be a sticking point in Greco-Turkish relations for decades to come.
Since the 1970s further issues arose between the two countries over sovereignty rights in the Aegean Sea. The Balkan Wars of 1913 had given Greece all the Aegean islands except Imbros and Tenedos, some of them only a few kilometres (barely more than three nautical miles) off the Turkish coast. Since the end of World War II, Turkish officials insisted that this led to questions regarding the delimitation of territorial waters, air space and other related zones of control. The conflict was motivated both by considerations of military tactical advantages and by questions of economic exploitation of the Aegean. The latter issue became particularly significant as after 1970 there were expectations of finding oil in the Aegean. This was highlighted during the crisis in 1987, when a Turkish ship was about to enter disputed waters to conduct an oil survey. The Greek Prime Minister of the time, Andreas Papandreou, ordered the ship to be sunk if found within disputed waters claimed by Greece. Consultations about this issue were held in Davos between the Greek and Turkish Prime Ministers.
Issues unresolved to this day concern the mutual delimitation of several zones of control:
- The width of the territorial waters. Both sides currently possess 6 nautical miles (11 km) off their shores in the Aegean Sea. Greece claims a right to unilateral expansion to 12 nautical miles, based on the International Law of the Sea. Turkey, which already has expanded its own territorial waters to 12 miles on its other coasts, denies the applicability of the 12-miles rule in the Aegean and has threatened Greece with war in the case it should try to apply it unilaterally.
- The width of the national airspace. Greece currently claims 10 miles, while Turkey only acknowledges 6 miles.
- The future delimitation of the continental shelf zone in the international parts of the Aegean, which would give the states exclusive rights to economic exploitation.
- The right of Greece to exercise flight control over Turkish military flight activities within the international parts of the Aegean, based on conflicting interpretations of the rules about Flight Information Regions (FIR) set by the ICAO.
- Since 1996, the sovereignty over some small uninhabited islets, most notably Imia/Kardak.
The conflict over military flight activities has led to a practice of continuous tactical military provocations. Turkish aircraft regularly fly in the zones over which Greece claims control (i.e., the outer four miles of the claimed Greek airspace and the international parts of Athens FIR), while Greek aircraft constantly intercept them. Aircraft from both countries frequently engage in mock dogfights. These operations often cause casualties and losses for both the Greek and Turkish Air Forces.
- On 18 June 1992, a Greek Mirage F1CG crashed near the island of Agios Efstratios in the Northern Aegean, during a low-altitude dogfight with two Turkish F-16s. Greek pilot Nikolaos Sialmas was killed in the crash.
- Οn 8 February 1995, a Turkish F-16C crashed on the sea after being intercepted by a Greek Mirage F1CG. The Turkish pilot Mustafa Yildirim bailed out and was rescued by a Greek helicopter. After brief hospitalization in Rhodes, the pilot was handed over to the Turkish side.
- On 27 December 1995, a pair of Greek F-16Cs intercept a pair of Turkish F-4E. During the dogfight that followed, one of the Turkish aircraft went into a steep dive and crashed into the sea, killing its pilot Altug Karaburun. The co-pilot Ogur Kilar managed to bail out safely and was rescued by a Greek ΑΒ-205 helicopter. He was returned to Turkey after receiving first aid treatment in Lesbos.
- On 8 October 1996, a pair of Greek Mirage 2000s intercepted a pair of Turkish F-16s (a single-seater C and a two-seater D) over the Aegean island of Chios. The F-16s were escorting 4 Turkish F-4Es on a simulated SEAD mission. After a long dogfight, one of the Turkish F-16s was allegedly shot down with a Magic II missile fired by a Greek Mirage 2000 piloted by Thanos Grivas. The Greek authorities said that the jet went down due to mechanical failure, while the Turkish Defense Ministry said, on 2014, that the jet had been shot down by the Greek pilot. Some Greek media outlets reported that it was an accident and the Turkish plane had unintentionally been shot down. Turkish pilot Nail Erdoğan was killed whereas back seater pilot Osman Cicekli bailed out. He was rescued by a Greek helicopter and handed over to the Turkish side. Greece officially offered to assist Turkey in its efforts to locate and salvage the Turkish fighter jet. On 2016, Turkish prosecutors have demanded two aggravated life sentences for the Greek pilot who allegedly downed the Turkish F-16 jet. The indictment demanded that Greek Mirage 2000 pilot Thanos Grivas be sentenced to two aggravated life sentences on charges of “voluntary manslaughter” and “actions for weakening the independence of the state.” It also demanded another 12 years for “vandalizing the jet.” Greece rejected the demands of the Turkish prosecutors.
- On 23 May 2006, a Greek F-16 and a Turkish F-16 collided approximately 35 nautical miles south off the island of Rhodes, near the island of Karpathos during a Turkish reconnaissance flight involving two F-16Cs and a RF-4. Greek pilot Kostas Iliakis was killed, whereas the Turkish pilot Halil İbrahim Özdemir bailed out and was rescued by a cargo ship.
- On 16 February 2016, Turkey prevented the Greek PM's aircraft carrying the Greek PM and Greece's delegation from landing on the island of Rhodes for refueling during their trip to Iran, arguing that the island is a demilitarized zone. Turkey also refused to accept the flight plan submitted by the Greeks, mentioned that the plane will not be allowed to enter Turkish airspace. Greeks created a new flight plan, the plane flew over Egypt, Cyprus, Jordan and Saudi Arabia so as to reach Iran, according to the new plan.
- On 12 February 2018, near midnight, the 1700 ton SG-703 Umut of the Turkish Coast Guard rammed into the 460 ton Stan Patrol OPV-090 Gavdos of the Hellenic Coast Guard. No injuries were reported but Gavdos received considerable damage on her port stern side. The incident took place in Greek territorial waters east of Imia.
- On 12 April 2018, a Greek Air Force Mirage 2000-5 fighter jet crashed into the Aegean Sea, killing the pilot Capt. Giorgos Baltadoros, 33, as he returned from a mission to intercept Turkish aircraft that had violated Greek air space. The Hellenic Air Force lost contact with the Mirage jet at 12.15, while the aircraft was about 10 miles northeast of Skyros.
- On 17 April 2018, two Turkish fighter aircraft harassed the helicopter carrying Greek Prime Minister and the Greek Armed Forces Chief, as they were flying from the islet of Ro to Rhodes. The Turkish jets contacted the pilot of the Greek helicopter and asked for flight details. The Hellenic Air Force (HAF) responded by sending its own jets, which caused the Turkish fighters to leave.
- On 25 March 2019, the Greek Prime Minister accused Turkey of harassing his helicopter while he was traveling to Agathonisi for the Greek independence day celebration. Turkey rejected the accusations, saying that the fighter jets were carrying out a routine mission.
- On 18 April 2019, Anadolu Agency wrote that after some foreign media claimed that Turkish fighter jets harassed the helicopter which was carrying the Greek army general during its travel to Kastelorizo, the Turkish army dismissed the claims saying that there was no approach that posed a danger to the Greek helicopter, adding that the aircraft belonging to the Turkish Air Forces were on regular duty in the Aegean.
- In March 2020, Greece summoned Turkey's ambassador to lodge a complaint after the Greek coastguard said one of its vessels had been rammed deliberately by a Turkish coastguard boat.
- On 3 May 2020, Greek officials said that two Turkish fighters harassed the helicopter which was transferring the Greek Defense Minister and the Greek Chief of the National Defense General Staff, after the helicopter took off from the island of Oinousses. In response 2 Mirage 2000s were sent to intercept the Turkish F-16s which was caught on video and released by the Hellenic air force. The Greek Ministry of Defense provided photos of the incident showing the Turkish aircraft.
Evros River incident
In 1986, Turkish and Greek soldiers suffered casualties at the Evros River incident, due to fire exchange. Turkish and Greek soldiers have exchanged fire in the past, as Greeks have tried to stop Iranian refugees from entering the country illegally from Turkey, but this incident was the first in which there have been casualties. During this period, Greek soldiers along the border with Turkey were on alert after receiving reports that Turkey planned to help thousands of refugees slip into Greece illegally. After the incident, top military and civilian authorities from both countries met to discuss a border protocol aimed at preventing future confrontations.
In 1987, the Sismik incident nearly started a war between Greece and Turkey.
Cyprus S-300 Crisis
During the Cypriot S-300 crisis, between early 1997 and late 1998, tensions continued between Greece and Turkey, due to Greece's support of the Cypriot position. The confrontation was sparked by Cypriot plans to install two Russian-made S-300 air-defence missile sites on their territory, provoking Turkey into threatening an attack or even all-out war if the missiles were not returned to Russia. The crisis effectively ended in December 1998 with the decision of the Cypriot government to transfer the S-300s to Greece's Hellenic Air Force in exchange for alternative weapons from Greece.
Capture of Öcalan and the resignation of Greek ministers
In 1999, Abdullah Öcalan, the leader of the Kurdistan Workers' Party, was captured by the Turkish Intelligence Service agents in Nairobi, Kenya, while leaving the Greek Embassy. Öcalan was carrying both Greek and Cypriot passports. Fearing a hostile Turkish reaction, three Greek ministers resigned: Foreign Minister Theodoros Pangalos, in charge of the attempt to hide Öcalan at the Greek Ambassador's residence in Kenya and to find him asylum; Interior Minister Alekos Papadopoulos, in charge of the Greek Intelligence Service involved in the operation; and Public Order Minister Philippos Petsalnikos, in charge of the Greek security forces which failed to stop the smuggling of Öcalan into Greece in January 1999.
Relations between Greece and neighbouring Turkey improved after successive earthquakes hit both countries in the summer of 1999. The so-called "earthquake diplomacy" generated an outpouring of sympathy and generous assistance provided by ordinary Greeks and Turks in both cases. These acts were encouraged from the top and took many foreigners by surprise, preparing the public for a breakthrough in bilateral relations, which had been marred by decades of hostility over anti-Greek pogroms, territorial disputes and the situation in the divided island of Cyprus.
Ten years later, Greece has become one of the key supporters of Turkey's struggle to enter the European Union. Yet, despite the confidence Greece and Cyprus have shown, voting YES for Turkey in order to begin its entry negotiations with the European Union in October 2005, many key issues remain unresolved. Furthermore, Turkey still denies access to Cypriot vessels to its territory, an obligation towards the EU with a 2006 deadline. The Turkish government counters that this restriction regarding Cypriot vessels was taken after the trade embargo decision against the portion of Cyprus illegally occupied by Turkey. The issue remains deadlocked, despite UN and EU attempts to mediate. Other unfulfilled obligations include Christian minority rights, acknowledgement of the Orthodox Church of Constantinople and the role of the Ecumenical Patriarch.
In 2002, Turkey and Greece made an unsuccessful attempt to jointly host the 2008 UEFA European Football Championship. The bid was one of the four candidacies that was recommended to the UEFA Executive Committee, the joint Austria/Switzerland bid winning the right to host the tournament.
A sign of improved relations was visible in the response to a mid-air collision by Greek and Turkish fighter jets in the southern Aegean in May 2006. While the Turkish pilot ejected safely, the Greek pilot lost his life. However, both countries agreed that the event should not affect their bilateral relations and made a strong effort to maintain them by agreeing to a set of confidence-building measures in the aftermath of the accident.
In December 2011, the Turkish newspaper Birgun reported on an interview with former Turkish prime minister Mesut Yilmaz saying that Turkey was behind a number of large forest fires in Greece in the 1990s. Yilmaz later denied the statements, saying he had been misquoted by the newspaper and that he had been actually referring to unsubstantiated reports of Greek involvement in Turkish forest fires. However, despite Yilmaz's denial, the allegations strained the relations between the two countries. Also, former head of Greek intelligence service said they had intelligence that Turkish agencies were involved in the arsons in the 1990s but had no proof. He said they had received information from their agents in Turkey that Turkish agents or others were involved in the forest fires on Greek islands.
Turkey is a transit point for illegal immigrants trying to reach Europe (as well as being a destination itself; see Immigration to Turkey for details). As a result of bilateral negotiations, a readmission agreement was signed between Turkey and Greece in November 2001 and went into effect in April 2002. For third-country nationals, this protocol gives the parties 14 days to inform each other of the number of persons to be returned after the date of illegal entry. For nationals of the two countries the authorities can make use of simplified procedures. But the strict application of the agreement is reported to have retrograded as of 2003. Incidents concerning illegal immigration are frequent on the border of the two countries. Turkey, which is a transit point for illegal immigrants trying to reach Europe, has been accused of not being able to secure its borders with Greece. Since 1996 40 illegal immigrants have been killed by mines, after entering Greek territory in Evros. In 2001, about 800 illegal immigrants were rescued by the Greek coast guard after a fire broke out on board the Turkish-flagged Brelner, believed to have set sail from the Turkish port of İzmir, probably en route to Italy. According to Greek sources the Turkish authorities are tolerant of smugglers trafficking illegal immigrants into Greece; a notable such incident is the one of a trafficking boat, filmed on September 14, 2009 by the Latvian helicopter crew of Frontex patrolling near Farmakonisi island, during which "it is clear that the Turkish coastguard, at best, does not prevent the "slavetrade" vessels to sail from its shores. At worst, it accompanies them into Greek territorial waters". The human trafficking into Greece through the Aegean Sea has been a documented, widespread phenomenon while "the failure, reported by Frontex, of Turkish officials to stop suspicious vessels as they leave, ensure that a steady stream of migrants reaches Lesbos and other islands in the Aegean".
On July, 2016, after the failed Turkish coup d'état attempt Greek authorities on a number of Aegean islands have called for emergency measures to curtail a growing flow of refugees from Turkey, the number of migrants and refugees willing to make the journey across the Aegean has increased noticeably after the failed coup. At Athens officials voiced worries because Turkish monitors overseeing the deal in Greece had been abruptly pulled out after the failed coup without being replaced. The Association of Greek Tourism Enterprises (SETE) warned about the prospect of another flare-up in the refugee/migrant crisis due to the Turkish political instability.
In June 2018, Turkey suspended its bilateral migrant readmission deal with Greece in response to the decision by the Greeks to release the eight Turkish soldiers who fled to Greece after the 2016 Turkish coup d'état attempt. NATO Secretary-General Jens Stoltenberg has called for “restraint and calm” after Turkey's decision.
In August 2019, about 650 people reached Lesbos from the Turkish coast in one day. It was the first mass arrival from Turkey since the 2016 EU-Turkey deal on migrant crisis. The Greek Foreign Minister summoned the Turkish ambassador to "express Greece’s deep discontent". The Turkish ambassador said that Ankara was "committed" to the deal and that its policy had not changed after being asked how so many were managing to make it Greek shores. In the first two weeks of August 2019, 1,929 people arrived on Lesbos from Turkey, compared with 479 in the same period last year. Due to high influx of immigrants from Turkey into Greece in 2019, the Greek Minister for Civil Protection Michalis Chrysochoidis warned that a new migrant crisis, like the previous one, will repeat if the situation were to continue.
In March 2020, Turkish president Erdogan accused the Greek security forces of Nazi tactics against migrants at border and also of shooting dead four migrants, calling Greece to let migrants cross its territory to reach richer western European countries. Greece rejected the claims as “fake news”, adding that it has a duty to protect the EU border. Tens of thousands of migrants were trying to get into Greece since Turkey said in February 2019 it would no longer keep them on its territory.r

In 1955 a Turkish usher at the Turkish consulate in Thessaloniki planted a bomb, which was sent from Turkey. The Turkish press accused the Greeks for the bomb and an organised mob attacked the Greek minority of Istanbul resulting in Istanbul pogrom.
Sledgehammer (coup plan)
During the 2010 trial for an alleged plot to stage a military coup dating back to 2003, named Sledgehammer, the conspirators were accused of planning attacks on mosques, triggering a conflict with Greece by shooting down one of Turkey's own warplanes and then accusing Greeks of this and planting bombs in Istanbul to pave the way for a military takeover.
Accession of Turkey to the European Union
After 1996, Greek Foreign Minister, and later Prime Minister, George Papandreou charted a major change of direction in Greek–Turkish relations. He lifted Greece's objections to Turkey's EU aspirations and energetically supported Turkey's bid for EU candidate status.
In September 2017, Greek Prime Minister, Alexis Tsipras, mentioned that halting accession talks with Turkey would be a strategic mistake by the European Union, amid a war of words raging between Germany and Turkey. Also, former Greek Prime Minister, George Papandreou, has urged European Union leaders to keep the doors open to Turkey and to continue dialogue with the Turkish government, in an apparent reference to German Chancellor Angela Merkel’s calls for the suspension of accession talks with Turkey.
DHKP-C and other organizations
In November 28, 2017, Greek police raided apartments in Athens and detained nine Turks (one woman and eight men), members of the DHKP-C, plotting to assassinate Recep Tayyip Erdoğan using rockets, during his visit to Greece.
In February 2018, a suspected member of the DHKP-C, against whom there was an Interpol red notice, was arrested while trying to enter into Greece. In June 2018, a Greek court ordered the extradition of this person to Turkey.
In April 2021, the Turkey's Communications Director, Fahrettin Altun, said that Greece support, train and help terrorist organizations to attack against Turkey. Adding that the attacks include suicide bombings. Furthermore, he said that terrorists are staying in refugee camps in Greece. In the organizations he included the DHKP-C, PKK and FETÖ.
In March 2018, Turkey detained two Greek military officers who crossed into Turkey, by mistake, while following the trail of suspected illegal migrants. Turkish courts have ordered their detention on suspicion of illegal entry and attempted military espionage. In April 2018, Greece said that Turkey appeared to be seeking some political leverage by continuing to hold the soldiers without trial for more than a month. In April, EU Commission President Jean-Claude Juncker said that the Turkish claim that the soldiers posed a threat is ridiculous. In addition, Turkish President Recep Tayipp Erdogan said he would consider releasing the soldiers if eight Turkish servicemen, who sought asylum in Greece following the failed 2016 coup attempt, were sent back to Turkey first. The Greek side has described this as "blackmail", with the Defence Ministry describing the soldiers as "hostages". Greek President said: "There was an unacceptable connection made between the Greek officers who were arbitrarily detained, and Turkish citizens who came to Greece and requested asylum. Because Greece implemented - I emphasize this - implemented international law, it was granted. These are two totally different cases and any confusion is unthinkable" In August 2018, the Turkish court ruled for the two soldiers' release, pending trial, adding that there were no reasons to kept them in pretrial detention. They are released and returned to Greece after being held for almost 6 months without any charges being pressed against them. Meanwhile, on 2 May 2018, a Turkish municipal worker was arrested after he illegally crossed to Greece near Kastanies. He stated that he accidentally crossed the border while carrying out construction work. On 5 May 2018, he returned to Turkey.
On September 9, 2018, two Turkish soldiers were arrested by Greek patrol units. According to the Turkey's General Staff, the soldiers were chasing irregular migrants when they crossed the border by mistake. The soldiers released and returned to Turkey the same day, after the Turkish side held talks with the Greek authorities. The Turkish defence Minister Hulusi Akar said that “positive and constructive attitude by the two countries gave out a good example of the neighbourly relations.”
Other events in 2015
Official relations between Greece and Turkey had improved, mainly due to the Greek government's supportive attitude towards Turkey's efforts to join the EU, although various issues have never been fully resolved and remain constant sources of conflict. An attempt at rapprochement, dubbed the Davos process, was made in 1988. The retirement of Greek Prime Minister Andreas Papandreou contributed to this improvement. His son, a foreign minister George Papandreou, made considerable progress in improving relations. He found a willing partner in Ismail Cem and later in the Turkish Prime Minister Recep Tayyip Erdoğan.
Tensions continued to be high over Turkish military activities that Greece regards as violations of Greek national sovereignty rights at sea and in the air. In March 2015 the Turkish forces had intended to carry out a military exercise in the Aegean disrupting international air traffic, and restricted traffic around two Greek national airports. Turkey subsequently withdrew the earlier Notice to Airmen (NOTAM) reserving an extensive area of air space over the Aegean from March 2 to December 31, 2015. The Greek government lodged complaints with NATO, the European Union, the United Nations, and the International Civil Aviation Authority over this flashpoint and NATO was thought to have played a role de-escalating.
In 2016, Greece named Turkey an “honorary country” together with Israel, Russia and the United States. Every year four countries are selected by Greece as “honorary” and their citizens enjoy additional benefits and discounts at Greece.
On August 15, 2016, the Greek President Prokopis Pavlopoulos accused Turkey of unjustifiably closing the historic Greek Orthodox Sumela Monastery, dedicated to the Virgin Mary, in Turkey's Black Sea region during the celebrations for the Assumption of Virgin Mary/Dormition of the Mother of God. The Turkish Foreign Ministry responded to the Greek President that his remarks distorted the decision to temporarily close the Sumela Monastery do not comply with facts and imply demagogy far from the responsibility of a statesman.
On September 29, 2016, Turkish President Recep Tayyip Erdogan disputed Treaty of Lausanne. He said “We gave away the islands (in the Aegean) through the Treaty of Lausanne,”, “The islands, which if we care to shout (from the western Asia Minor coast) we’ll be heard on the other side (the islands), we gave away with Lausanne. What will now happen with the continental shelf? What will happen with the airspace and land? We’re still fighting for all of these". This caused displeasure in Athens. A Greek Foreign Ministry source remarked that “everyone should respect the Treaty of Lausanne,” noting that it is “a reality in the civilized world which no one, including Ankara, can ignore.”, added that the Turkish leader's comments were likely geared for domestic consumption.
On October 16, 2016, Turkish President Recep Tayyip Erdogan said, “We cannot draw boundaries to our heart, nor do we allow it,” and that “Turkey cannot disregard its kinsmen in Western Thrace, Cyprus, Crimea and anywhere else.” Greece saw his speaking as an effort, informed by a neo-Ottoman narrative and romantic irredentism, to dispute past agreements that settled the borders between the two countries. Greek Foreign Ministry said, on October 17, that "Thrace is Greek, democratic and European. Any other thought is unthinkable and dangerous.”
2016 Turkish coup d'état attempt
After the failed July 2016 Turkish coup d'état attempt, several Turkish military personnel sought political asylum in Greece while Turkey requested their extradition. Also, the Greek armed forces and Coast Guard were on alert and increased the patrols and a contingent of the Greek Police was dispatched to some Greek islands to conduct checks there in order to prevent the arrival of participants in the failed coup to Greece and arrest anyone who might manage to enter the country.
Also, the two Turkish military attaches in Athens fled to Italy. The Greek Foreign Ministry cancelled the two attaches accreditations on August 7, 2016, upon the request of the Turkish Foreign Ministry. At August 11, 2016, the Turkish Foreign Minister Mevlut Cavusoglu said that they left Greece to Italy on August 6 and added that Turkey will officially ask Italian authorities to extradite the two soldiers.
On August 25, 2016, seven Turkish citizens were seeking asylum in Greece. A couple, both of whom are university professors, and their two children applied for asylum in Alexandroupoli after they illegally entered the country from the northeastern border. Also, three businessmen have illegally reached the Greek island of Rhodes, and they also applied for asylum.
On August 30, 2016, a Turkish judge arrived to the Greek island of Chios on a migrant boat and sought asylum in the country. He told the Greek coast guard and police officers that he is being persecuted in Turkey for his political beliefs by the government of President Tayyip Erdogan. The Turkish judge had been arrested for illegally entering the country and, also, he transferred to Athens for his asylum proceedings.
On September 21, 2016, ten Turkish civilians, two men, two women and six children landed by boat illegally on the Greek island of Rhodes and sought asylum. They told the Greek authorities they were working in the private sector in Turkey and they were being persecuted by the Turkish government due to their political beliefs.
On 15 February 2017, five Turkish commandos illegally entered Greece through the Evros river. However, once they entered the country, the group split. Two of them surrendered to the police and on 20 February 2017, requested political asylum. The Greek government announced that the Greek authorities will not allow the country to be dragged into the ongoing feud between the Turkish state and the followers of Gulen. But there was no sign of the other three. According to a lawyer, there were indications that the other three had been arrested by Greek authorities who were about to expel them to Turkey. Later, according to new evidence and new information these three “arrested” marines were delivered under fast and informal procedures from Greek to Turkish services.
On October 24, 2017, Turkish authorities obtained information that 995 Turks have applied for asylum in Greece after the coup attempt. More than 1,800 Turkish citizens requested asylum in Greece in 2017.
On March 27, 2017, the former editor in chief of the English version of the Turkish newspaper Zaman, Abdullah Bozkurt, posted a tweet on his account warning of increased clandestine operations of Turkish intelligence agents in Greece.
On August 16, 2017, Turkish Foreign Minister Mevlut Cavusoglu speaking before Turkey's National Assembly, said that a number of interconnected problems remain in the Aegean between the Turkey and Greece. “Among these problems is the question of sovereignty of certain islets and rocky formations, and the fact that there are no sea borders which are set by an international agreement between Turkey and Greece,” he said.
On August 22, 2017, the Erbakan Foundation (a religious foundation) at Sinop staged a protest, demanding the removal of a statue of the ancient Greek philosopher who was born at Sinop, Diogenes, from the city entrance. The foundation said it was protesting the fact that the Greek ideology being attached to the province.
In December 2017 Recep Tayyip Erdogan became the first Turkish president to visit Greece in 65 years. Also, the Republican People's Party (CHP) leader Kemal Kılıçdaroğlu in a speech at the parliament criticized Recep Tayyip Erdoğan over his "failure" to raise the issue of "18 occupied islands" during his visit to Greece. His political party also declared the Turkish names of 156 islands, islets and reefs in the Aegean Sea and claimed them as Turkish territory. The Greek Defense minister, Panos Kammenos, responded "come and get it". Kılıçdaroğlu then said, that Turkey will come and take all of those islands back, while the CHP's deputy leader for foreign affairs, Öztürk Yılmaz, said that "Greece should not test our patience".
On April 10, 2018, Greek soldiers fired warning shots at a Turkish helicopter approaching the island of Ro. The helicopter was flying at a very low altitude late at night with its navigation lights switched off.
On April 16, 2018, Turkish Prime Minister Binali Yıldırım said that on April 15, Greek citizens planted a Greek flag on an uninhabited rocky islet at the Aegean, but the Turkish coast guard removed the flag. In addition, urged the Greek government to refrain from “provocative moves” in the "disputed areas" of the Aegean Sea. The Greek government responded that there was no evidence indicating "violation of Greek territory" and labeled the claims as "totally provocative and reprehensible".
In August 2018, the former lawmaker for the Peoples' Democratic Party (HDP), Leyla Birlik, requested asylum in Greece after illegally crossing the border near Alexandroupolis.
In September 2018, the Turkish Agriculture and Forestry Ministry warned Turkish fishers not to enter the territorial waters of Greece. “In order to prevent unwanted incidents and accidents, and to abstain from activities that would harm our country’s legal and political theses and ones which we would be unable to explain or defend,” after several complaints were handed to Turkey's Foreign Ministry saying Turkish fisher boats had entered Greece's territorial waters.
On March 14, Turkish president Recep Tayyip Erdogan, during an interview, said that whenever Greek military aircraft take off in the Aegean, Turkish jets will follow suit. The next day the Greek Ministry of Foreign Affairs issued a press release saying that "Turkey’s effort to equate the flights of Turkish military aircraft that violate Greece's national sovereignty with the identification and interception missions the Hellenic Air Force carries out in defense of national sovereignty, is completely unacceptable", adding that "Turkish military aircraft violate Greek national air space on an almost daily basis, including through low-altitude overflights of inhabited Greek islands. This is a practice that Greece systematically condemns and reports, both bilaterally as well as to the competent international bodies." The ministry also said that the legal status in the Aegean is "clear and fully enshrined" in International Law, "leaving no room for doubt". The Turkish Foreign Ministry spokesperson responded that Greece calling Turkey's flights over the Aegean Sea a “threat” is incompatible with alliance and good neighborly relations, adding that the Greek Foreign Ministry's statement was "odd" in both its timing and content.
On March 17, Turkish president Recep Tayyip Erdogan during a speech in İzmir along with Gray Wolves leader Devlet Bahceli, made a reference to the Asia Minor Catastrophe saying: "[...] Smyrna you that you throw the infidels in the sea and protect the helpless". This statement prompted the response of the Greek Ministry of Foreign Affairs, stating that "Greece is not going to be swept away in the instrumentalisation of foreign policy to serve domestic political expediencies, or use history with terms that are offensive to neighbouring countries. Such unacceptable references undermine the trust we hope to build between our countries and are not in line with the European perspective that the Turkish leadership claims to support."
On March 22, Turkish Defense Minister Hulusi Akar stated that Turkey "control(s) the sea and the seabed. The seas. The Black Sea, the Aegean, the Eastern Mediterranean which also includes Cyprus" adding that "these areas lie within our sphere of interest… we have the responsibility of ensuring peace and calm". The Greek Defense Minister Evangelos Apostolakis issued a statement saying that although Greece is "struggling" to defuse tension "Akar surprised us with something new, with things that are not based on reason" adding that "it is the principle of Greece that we respect international law and the treaties" and "when these principles are questioned, we have to be concerned".
2019 Turkey-Libya agreement over the sea boundaries and Greek reaction
On November 27, 2019, Turkey and Libya signed a deal. The agreement, unveiled on December 5, maps out a sea boundary between the two countries, cutting across a part that is also claimed by Greece. Greek Foreign Minister Nikos Dendias called the Turkey-Libyan accord a "blatant violation of international law". Greek authorities were taken by surprise by the accord, after Libyan officials assured them the deal would not be signed off. Greece on December 6 expelled the Libyan ambassador. Mitsotakis told the Greek parliament “They are oblivious to history and geography as they do not take Greek islands into account,” adding that Ankara's move is forcing them into “unprecedented diplomatic isolation”. Turkey condemned Greece's decision to expel the Libyan ambassador.
In December, Greece sent two letters to the United Nations explaining its objections and asking for the matter to be taken up by the U.N. Security Council, while Turkey notified the United Nations of its delimitation of the maritime jurisdiction areas with Libya. The United Nations remained neutral and urged Greece and Turkey to maintain a dialogue. The head of the Tobruk parliament (Libya's eastern-based parliament) expressed his disagreement over the agreement during a visit to Greece. Greece followed by establishing a legal maritime accord with Egypt, while maintaining its legal right to implement a 12-mile maritime by law that is currently only 6.
In early 2020, western security officials reported a pattern of cyber attacks against governments and other organizations in Greece and other European and Middle Eastern countries in late 2018 and early 2019, which they described as resembling a "state-backed cyber espionage operation conducted to advance Turkish interests". Turkey's officials declined to comment.
Coast guard incidents
In early 2020, Greek authorities released a number of videos apparently showing Turkish Coast Guard vessels harassing Greek ones and escorting migrants and refugees into Greece, in the northeast Aegean Sea.
On June 10, 2020, a Greek frigate under the command of the European Union's Operation Irini attempted to inspect the Tanzanian-flagged cargo vessel Çirkin which was suspected of carrying arms to Libya, but was ordered to retreat after warnings from Turkish frigates accompanying the cargo vessel. Later, Turkish navy also stopped a French warship from the NATO Operation Sea Guardian from inspecting the vessel. On 21 September 2020, the EU sanctioned the Turkish maritime company Avrasya Shipping which operates the Çirkin freighter, because the vessel found to have violated the arms embargo in Libya in May and June 2020.
On November 22, 2020, the German frigate Hamburg intercepted a Turkish freighter near Libya and soldiers from the frigate boarded the Turkish ship in order to search it, but had to abandon checks and withdraw after Turkey protested. Turkish President Erdoğan accused Greece for “provocations” because the man in charge of the operation during that incident was a Greek official. European Union in an official statement said that the inspection followed the internationally agreed procedures, including NATO procedures and that the Irini operation is in accordance with the UN Security Council Resolutions 2292 (2016) and 2526 (2020) and that the UN Security Council Resolution 2292 (2016) calls upon all flag States to cooperate with inspections. These resolutions are binding for all UN Member States, including the Turkey.
Greek and Turkish warship and other tensions
In mid-August 2020, tensions between the two countries have risen after Turkey sent a survey vessel RV MTA Oruç Reis to the region, escorted by warships, to map out sea territory for possible oil and gas drilling in an area where Turkey and Greece both claim jurisdiction. On 25 August 2020, it was reported that Greece and Turkey are planning rival naval exercises off Crete amid an escalating row over energy claims in the region. Greek media have reported that purchases consisting of French-made Rafale fighter jets and at least one French frigate will be made.
Greece accused Turkey's authorities that on 14 October weren't granting permission to the plane of the Greek Foreign Minister to fly through the Turkish airspace, back to Greece from Iraq. The plane was kept circling over Mosul for 20 minutes before Turkish authorities grant it permission. According to the Turkey's Foreign Ministry, the first plane that carried Greek Foreign Minister to Iraq broke down before going back to Greece, and Greece assigned another plane. The second plane hadn't provided the required flight plan, and after the plan was received from the Iraqi authorities the flight was carried out safely.
In September 2020, RV MTA Oruç Reis returned back toward shore to ease tensions. However, the EU decided to impose sanctions on Turkey in December 2020, over its gas drilling activities and foreign policy in general.

- In an article published in Byzantine and Modern Greek Studies Archived 2007-09-29 at the Wayback Machine ("George Horton: The literary diplomat)", Brian Coleman describes his subject matter as follows: "George Horton was a man of letters and United States Consul in Greece and Turkey at a time of social and political change. He writes of the re-taking of Smyrna by the Turkish army in September 1922. His account, however, goes beyond the blame and events to a demonization of Muslims, in general, and of Turks, in particular. In several of his novels, written more than two decades before the events of September 1922, he had already identified the Turk as the stock-in-trade villain of Western civilization. In his account of Smyrna, he writes not as a historian, but as a publicist."
