Castilian nationalism

Castilian nationalism, or "Castilianism" (Spanish: Castellanismo), is a political movement that advocates for the national recognition of Castile, and in some cases, its independence.

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.

April 23 is commemorated as Castilian National Day after the defeat of the comuneros at the Battle of Villalar, in 1521.
