In December 1971, on the Karađorđevo conference of the SKJ, Tito publicly distanced himself from Croatian Spring, leading to the end of the movement.
Due to the alleged "Croat nationalism", having been denounced after signing the Declaration on the Status and Name of the Croatian Standard Language, and after the coup in Karađorđevo (1971) he was forcefully retired in 1973.
That, and Croatian students making even more radical demands, finally led Tito to openly turn against Savka and Tripalo at Karađorđevo Party conference in December 1971.
In December 1971 Tito held a party leadership conference in Karađorđevo, Serbia, and publicly turned against the Croatian Spring in the form of "comradely critic", (an internal communist way to openly criticize its party members when they, according to majority opinion, do not follow "the party line").
