Yugoslavia failed to consist of the coterminous Balkan peninsula.
In 1974, the two provinces of Vojvodina and Kosovo-Metohija (for the latter had by then been upgraded to the status of a province), as well as the republics of Bosnia and Herzegovina and Montenegro, were granted greater autonomy to the point that 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 1974, Serbia's influence in the country was significantly reduced as autonomous provinces were created in ethnic Albanian-majority populated Kosovo and the mixed-populated Vojvodina
