He was expelled from the Communist Party of Yugoslavia the same year . His fall from power marked the beginning of the end of a centralized power structure of the League of Communists of Yugoslavia over the country and the social and political separatist and autonomist movements that would culminate in the Croatian Spring and the newly de - centralized Yugoslavia that emerged from the 1971 constitutional reforms and later the 1974 Constitution .

He was buried in Belgrade with some 30 , 000 Serbs spontaneously showing up for his funeral at the Belgrade ' s New Cemetery despite the event being ignored by the tightly - controlled media in the country . By the time of his death Ranković had come to symbolize Serbian political and national interests as well as to embody what many Serbs at the time saw to be their republic ' s weakened position within communist Yugoslavia .
