Some Castilian nationalists defend the traditions and values from the rebels of the Castilian War of the Communities, so they call themselves "comuneros". Some of them also contend for the union of the present-day Spanish Autonomous Communities of Cantabria, Castile and León, Castile-La Mancha, La Rioja and Madrid.
