White-red-white flag
The white-red-white flag is a historical flag used by the Belarusian Democratic Republic in 1918 before Western Belarus was occupied by the Second Polish Republic and Eastern Belarus was occupied by the Bolsheviks (two years later becoming the Belarusian SSR). The flag was then used by the Belarusian national movement in Western Belarus followed by use during the German occupation of Belarus between 1943 and 1944, and again after it regained its independence in 1991 until the 1995 referendum.
