The Socialist Federal Republic of Yugoslavia, formed after Josip Broz Tito and his communist-led Partisans had helped liberate the country from German rule in 1944–45, covers much the same territory as its predecessor, with the addition of land acquired from Italy in Istria and Dalmatia.
When a new Soviet-style constitution is promulgated in January 1946, the political development of Serbia is once again merged with that of Yugoslavia.
In an effort to prevent Serbian domination of the new state, the regime makes separate republics of Montenegro and Macedonia and creates within Serbia itself an ethnically mixed Autonomous Province of Vojvodina and a mostly Albanian Autonomous Region of Kosovo.
A federation of six nominally equal republics—Croatia, Montenegro, Serbia, Slovenia, Bosnia and Herzegovina, and Macedonia—replaces the monarchy.
This new federation is intended to satisfy the national aspirations of all its peoples, but a centrally controlled Communist Party and a revived push for Yugoslav unity undermine this structure.
Despite its federal form, the new state is highly centralized both politically and economically, with power held firmly by Tito's Communist Party of Yugoslavia.
The Yugoslav system consists of three levels of government: the communes (opshtine), the republics, and the federation.
The 500 communes are direct agents for the collection of most government revenue, and they provide social services.
The constitution establishes a rubber-stamp Federal Assembly and a presidential council to administer the federal government.
It also includes restricted wording on the inviolability of the home, the right to work, freedom of speech, association, and religion, and other rights.
Tito heads the party, government, and armed forces; his party functionaries oversee the industries and supervise republican and local officials.
