Ante Pavelić was a Croatian politician who founded and headed the fascist ultranationalist organization known as the Ustaše in 1929 and was dictator of the Independent State of Croatia (NDH), a fascist puppet state built out of parts of occupied Yugoslavia by the authorities of Nazi Germany and Fascist Italy, from 1941 to 1945. Pavelić and the Ustaše persecuted many racial minorities and political opponents in the NDH during the war, including Serbs, Jews, Romani, and anti-fascists, becoming one of the key figures of the genocide of Serbs, the Porajmos and the Holocaust in the NDH.
At the start of his career, Pavelić was a lawyer and a politician of the Croatian Party of Rights in the Kingdom of Yugoslavia known for his nationalist beliefs and support for an independent Croatia. By the end of the 1920s, his political activity became more radical as he called on Croats to revolt against Yugoslavia, and schemed an Italian protectorate of Croatia separate from Yugoslavia.
