Eugen Dido Kvaternik was the son of
Slavko Kvaternik, a general in the
Independent State of Croatia army and a member of the Ustaše, and Olga Frank, daughter of
Josip Frank, a Catholic convert whose parents were Jewish. Kvaternik was sentenced to death in absentia by France for organizing the assassination of King
Alexander I of Yugoslavia. However, at the time, he was imprisoned by authorities in
Fascist Italy, who refused to hand him over for execution. He was released in 1936, having served two years, whereupon he joined the exiled Ustasha members on the island of
Lipari. He instituted a regime of terror against Serbs, Jews, Gypsies and other "enemies of the State". In 1943, after a falling-out with Pavelić, the leader of the Independent State of Croatia, he and his father, Slavko, the Croatian Minister of War, went into exile in
Slovakia, and after the war fled to
Argentina. From Argentina, he directed activities against
Josip Broz Tito. He reorganized Ustaše supporters and continued to publish actively.
Yugoslavia's multiple extradition requests were all turned down, and Kvaternik was never tried. Dido Kvaternik died in a car crash in
Río Cuarto, Argentina in 1962. ==Family==
