Wikipedia , "In the aftermath of the 1917 Russian Revolution, Belarus declared independence as the Belarusian People's Republic, succeeded by the Socialist Soviet Republic of Byelorussia, which became a founding constituent republic of the Soviet Union in 1922 and was renamed as the Byelorussian Soviet Socialist Republic (Byelorussian SSR). Belarus lost almost half of its territory to Poland after the Polish-Soviet war of 1919-1921. Much of the borders of Belarus took their modern shape in 1939 when some lands of the Second Polish Republic were reintegrated into it after the Soviet invasion of Poland and were finalized after World War II."
