The People's Socialist Republic of Albania (Albanian: Republika Popullore Socialiste e Shqipërisë) was the official name of Albania from 1976 until 1991. From 1946–1976 it was known as the People's Republic of Albania and from 1944 to 1946 as the Democratic Government of Albania. Throughout this period the country had a reputation for its Stalinist style of state administration dominated by Enver Hoxha and the Party of Labour of Albania and for policies stressing national unity and self-reliance. Travel and visa restrictions made Albania one of the most difficult countries to visit or to travel from. In 1967, it declared itself the world's first atheist state. It was the only Warsaw Pact member to formally withdraw from the alliance before 1990, an action occasioned by the Warsaw Pact invasion of Czechoslovakia in 1968. The first multi-party elections in Socialist Albania took place on 31 March 1991 – the communists gained a majority in an interim government and the first parliamentary elections were held on 22 March 1992. The People's Socialist Republic was officially dissolved on 28 November 1998 upon the adoption of the new Constitution of Albania.
