First Constituent Charter

The First Constituent Charter to the peoples of Belarus (Belarusian: Першая Ўстаўная грамата да народаў Беларусі, Pieršaja Ŭstaŭnaja hramata da narodaŭ Biełarusi) is a legal and political act issued by the Executive Committee of the Council of the All-Belarusian Congress on 21 February 1918 in Minsk (in the former Governor's House). She called on the Belarusian people to exercise their right to full self-determination, and national minorities — on national and personal autonomy.

The microfilmed original of the act is kept in the 325th fund of the National Archives of Belarus.
