Byelorussian Soviet Socialist Republic
In 1919 Vitebsk was proclaimed to be part of the Socialist Soviet Republic of Byelorussia (January to February 1919), but was soon transferred to the Russian Soviet Federative Socialist Republic and later to the short-lived Lithuanian–Byelorussian Soviet Socialist Republic (February to July 1919). In 1924 it was returned to the Byelorussian Soviet Socialist Republic.
