First All-Belarusian Congress

The First All-Belarusian Congress (Belarusian: Першы Ўсебеларускі кангрэс/Першая Ўсебеларуская канферэнцыя, romanized: Pieršy Ŭsiebiełaruski kanhres/Pieršaja Ŭsiebiełaruskaja kanferencyia) was a congress of Belarusian political organisations and groups held in Minsk in December 1917. The congress gathered 1872 delegates from all regions of Belarus and was violently dispersed by the Bolshevik military.

The congress played an important role in the consolidation of the Belarusian national liberation movement after the October Revolution in Russia. The council that was selected at the congress formed the Rada of the Belarusian Democratic Republic and on 25 March 1918 declared the independence of Belarus as the Belarusian Democratic Republic.
