North Ossetia–Alania replaces North Ossetian Autonomous Soviet Socialist Republic
Soviet period (1917–1990)
The Russian Revolution of 1917 resulted in North Ossetia being merged into the Mountain Autonomous Soviet Socialist Republic in 1921. It then became the North Ossetian Autonomous Oblast on 7 July 1924, then merged into the North Ossetian Autonomous Soviet Socialist Republic on 5 December 1936. In World War II, it was subject to a number of attacks by Nazi German invaders unsuccessfully trying to seize Vladikavkaz in 1942.
The North Ossetian ASSR declared itself the autonomous republic of the Soviet Union on 20 June 1990. Its name was changed to the Republic of North Ossetia–Alania in 1994.
