Austria. The 1948 Yugoslavia–Soviet split The country distanced itself from the Soviets in 1948 (cf. Cominform and Informbiro) and started to build its own way to socialism under the political leadership of Josip Broz Tito. Accordingly, the constitution was heavily amended to replace the emphasis on democratic centralism with workers' self-management and decentralization. The Communist Party was renamed to the League of Communists and adopted Titoism at its congress the previous year. All the Communist European Countries had deferred to Stalin and rejected the Marshall Plan aid in 1947. Tito, at first went along and rejected the Marshall plan. However, in 1948 Tito broke decisively with Stalin on other issues, making Yugoslavia an independent communist state. Yugoslavia requested American aid. American leaders were internally divided, but finally agreed and began sending money on a small scale in 1949, and on a much larger scale 1950–53. The American aid was not part of the Marshall plan. Tito criticised both Eastern Bloc and NATO nations and, together with India and other countries, started the Non-Aligned Movement in 1961, which remained the official affiliation of the country until it dissolved. In 1974, the two provinces of Vojvodina and Kosovo-Metohija (for the latter had by then been upgraded to the status of a province) were granted greater autonomy, along with greater rights for the Albanians of Kosovo and Hungarians of Vojvodina. Both provinces were afforded much of the same status as the six republics of Yugoslavia, though they could not secede. Vojvodina and Kosovo-Metohija formed the provinces of the Republic of Serbia but also formed part of the federation, which led to the unique situation in which Central Serbia did not have its own assembly but a joint assembly with its provinces represented in it. Albanian and Hungarian became nationally recognised minority languages, and the Serbo-Croat of Bosnia and Montenegro altered to a form based on the speech of the local people and not on the standards of Zagreb and Belgrade. In Slovenia the recognized minorities were Hungarians and Italians. SFR Yugoslavia On 7 April 1963, the nation changed its official name to Socialist Federal Republic of Yugoslavia and Josip Broz Tito was named President for life. In the SFRY, each republic and province had its own constitution, supreme court, parliament, president and prime minister. At the top of the Yugoslav government were the President (Tito), the federal Prime Minister, and the federal Parliament
