With the 1974 Constitution, the office of President of Yugoslavia was replaced with the Yugoslav Presidency, an eight-member collective head-of-state composed of representatives from six republics and, controversially, two autonomous provinces of the Socialist Republic of Serbia, SAP Kosovo and SAP Vojvodina. Since the SFR Yugoslav federation was formed in 1945, the constituent Socialist Republic of Serbia (SR Serbia) included the two autonomous provinces of SAP Kosovo and SAP Vojvodina. With the 1974 constitution, the influence of the central government of SR Serbia over the provinces was greatly reduced, which gave them long-sought autonomy.
