Southeast Europe or Southeastern Europe (SEE) is a geographical region of Europe, consisting primarily of the coterminous Balkan peninsula. There are many overlapping and conflicting definitions as to where exactly Southeastern Europe begins or ends or how it relates to other regions of the continent. Sovereign states that are most frequently included in the region are, in alphabetical order: Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Kosovo, Macedonia, Montenegro, Romania, Serbia, and Slovenia.
These boundaries can vary greatly due to political, economic, historical, cultural, and geographical considerations of the observer and as such are widely disputed.
This concept is based on the boundaries of the Balkan peninsula. The countries that have been described as being entirely within the region are: Albania, Kosovo, Bosnia and Herzegovina, Bulgaria, Macedonia and Montenegro.
