Socialist Republic of Montenegro , or SR Montenegro in shortened form, was one of the 6 republics forming the
Socialist Federal Republic of Yugoslavia. It is a predecessor of the modern-day
Montenegro. On 7 July 1963, the People's Republic of Montenegro was renamed the "Socialist Republic of Montenegro" (a change ratified both by the Federal Constitution and the newly created Montenegrin Constitution in 1963). It was a non-national
free state with
Serbo-Croatian as the official language. In 1991, as the League of Communists in Montenegro changed its name to Democratic Party of Socialists of Montenegro after the first free elections, the adjective "Socialist" was deleted from the republic's title (ratified by the 1992 Constitution).
