After the Bolshevik Revolution in 1917, the term ''White Russia'' caused some confusion, as it was also the name of the military force that opposed the red Bolsheviks. During the period of the Byelorussian SSR, the term ''Byelorussia'' was embraced as part of a national consciousness. In western Belarus under Polish control, ''Byelorussia'' became commonly used in the regions of Białystok and Grodno during the interwar period.
