Autonome Nationalisten (English: Autonomous Nationalists, abbreviated AN) are German, British, Dutch and to a lesser degree Flemish Nationalists, who have adopted some of the far-left and Antifa's organizational concepts (autonomous activism), demonstration tactics (black bloc), symbolism, and elements of clothing, including Che Guevara T-shirts and keffiyehs. Similar groups have also appeared in some central and eastern European countries, beginning with Poland (starting in 2009), the Czech Republic, Ukraine, Romania and Greece and others.
