SAPK meaning in Governmental ?

The Socialist Autonomous Province of Kosovo (Serbian: Социјалистичка Аутономна Покрајина Косово, romanized: Socijalistička Autonomna Pokrajina Kosovo; Albanian: Krahina Socialiste Autonome e Kosovës), comprising the Kosovo region, was one of the two autonomous provinces of Serbia within Yugoslavia (the other being Vojvodina), between 1945 and 1990, when it was renamed Autonomous Province of Kosovo and Metohija.

Between 1945 and 1963 it was officially named the Autonomous Region of Kosovo and Metohija, with a level of self-government lower than that of the Autonomous Province of Vojvodina. In 1963 it was granted the same level of autonomy as Vojvodina, and accordingly its official name was changed to Autonomous Province of Kosovo and Metohija. In 1968 the term "Metohija" was dropped, and the prefix "Socialist" was added, changing the official name of the province to Socialist Autonomous Province of Kosovo. In 1974 both autonomous provinces (Vojvodina and Kosovo) were granted significantly increased levels of autonomy. In 1989, under the presidency of Slobodan Milošević, that level of autonomy was reduced. In 1990 the term "Metohija" was reinserted into the provincial name, with "Socialist" being dropped. From that point on the official name of the province was once again Autonomous Province of Kosovo and Metohija, as it was previously between 1963 and 1968.
