This is a List of heads of state of Yugoslavia from the creation of the Kingdom of Serbs, Croats and Slovenes in 1918 until the breakup of the Socialist Federal Republic of Yugoslavia in 1992. The Kingdom of Yugoslavia was a monarchy ruled by the House of Karađorđević from 1918 up until World War II. The SFR Yugoslavia was headed first by Ivan Ribar, the President of the Presidency of the People's Assembly (president of the parliament), and then by President Josip Broz Tito until his death in 1980, when the a collective federal presidency rotated the presidency among the republic representatives. However, until 1990 the position of General Secretary of the League of Communists of Yugoslavia was usually the most powerful position (the position often coincided with the position of President)
