Witalis Karol Teodor Wieder (29 March 1895 – 22 February 1967) was a German-Polish traitor, a Nazi sympathizer, a recruited Agent of the Abwehr, and a self-proclaimed leader of the Goralenvolk during World War II. Goralenvolk were pro-Nazi traitors who claimed to originate from an aryan race, and who wanted to establish their own nation in the Polish mountains in Zakopane. Wieder acted as a Reichsdeutscher, and was known as a collaborator for the Nazi occupiers even though he was formerly an officer in the Polish army. At the end of the war, he escaped to Nazi Germany.
