The Socialist Republic of Macedonia (Macedonian: Социјалистичка Република Македонија, Socijalistička Republika Makedonija) was a socialist state that was a constituent country of the former Socialist Federal Republic of Yugoslavia. After the transition of the political system to parliamentary democracy in 1990, the Republic changed its official name to Republic of Macedonia in 1991, and with the beginning of the breakup of Yugoslavia, it declared full independence on September 8, 1991.
The modern Macedonian state was officially proclaimed under the name Democratic Macedonia on August 2, 1944, the day of the Ilinden Uprising against the Ottoman empire in 1903, at the First Plenary Session of ASNOM during the antifascist National Liberation War of Macedonia in the Second World War. This date is now celebrated by the ethnic Macedonians as the day when which they were first allowed to freely state their nationality.
In 1945, the state changed its official name to People's Republic of Macedonia. It was formally incorporated as a constituent republic in the former Yugoslav Federation in 1946. However, many people were against the federation, others demanded greater independence from the federal authorities, which led to their prosecution. One of the notable victims of these purges was the first president Metodija Andonov - Čento. In 1963, the name was changed to Socialist Republic of Macedonia.
