Ante Pavelić
Ante Pavelić (July 14, 1889 - December 28, 1959) was the leader and founding member of the Croat Ustashi movement in the 1930s and later the leader of the Independent State of Croatia.
Pavelić was the party secretary of the Croatian Party of Rights until 1929 and the beginning of royal dictatorship in the Kingdom of Yugoslavia. He then co-founded the Ustaše and went underground until the beginning of World War II. In 1941, Yugoslavia was invaded and he became the leader (poglavnik) of the Independent State of Croatia.
In May 1945 he fled via Bleiburg to Austria, where he stayed for a few months before transferring to Rome where he was protected by the Croatian Franciscans at San Girolamo, in particular friar Krunoslav Draganović who had previously been a member of the Ustaša army. Two years later, he was transferred to a monastery near Castel Gandolfo.
His stay in Rome was known to the American Counterintelligence Corps, but they apparently weren't interested in the arrest of any non-Communists from eastern parts of Europe. Six months later, he fled to South America via the rat lines.
Upon arriving in Argentina, he became security advisor to Juan Peron. Peron issued 34,000 visas to Croatians: both the Nazi collaborators and the anti-communists that fled from Communism imposed by Josip Broz Tito.
In April 1957 he was shot twice in an assassination attempt by the Royalist Serb Blagoje Jovović. He was subsequently forced to flee Argentina to avoid arrest and extradition, and he found refuge in Spain, where he died in Madrid in late 1959, from complications of his wounds.
