Following 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 Hrodna during the interwar period. Upon the establishment of the Byelorussian Socialist Soviet Republic in 1920, the term "Byelorussia" (its names in other languages such as English being based on the Russian form) was only used officially. In 1936, with the proclamation of the 1936 Soviet Constitution, the republic was renamed to the Byelorussian Soviet Socialist Republic transposing the second ("socialist") and third ("soviet") words.
