 After the death of Radić, Vlatko Maček became president of the Croatian Peasant Party and he enforced a more conservative and nationalist policy which was mostly aimed at creating an Independent Croatian nation-state while social issues were put aside.During World War II, while the Nazi puppet controlled Independent State of Croatia and Italy occupied modern Croatia territory, the only anti-fascist organised movement were the Yugoslav partisans who were created and led by the Communist Party of Yugoslavia and their commander Josip Broz Tito.In 1945, after the partisans won the war, Socialist Yugoslavia was established with a one-party system in which the Communist Party of Yugoslavia was the only legal political party.
