The Second Constituent Charter to the peoples of Belarus (Belarusian: Другая Ўстаўная грамата да народаў Беларусі, Druhaja Ŭstaŭnaja hramata da narodaŭ Biełarusi) is a legal act adopted by the executive committee of the Council of the All-Belarusian Congress on March 9, 1918, in Minsk.
[1] Adopted on February 21, 1918, the First Constituent Charter proclaimed the executive committee of the Council of the All-Belarusian Congress a temporary people's power in Belarus.
However, on March 3, 1918, Soviet Russia concluded the Brest Peace Treaty, according to which it transferred most of the territory of Belarus to the German Empire.
The Council of the All-Belarusian Congress, supplemented by representatives of the national minorities of Belarus, temporarily took over the legislative power in the country.
The basic laws of the Belarusian People's Republic were later to be approved by the Constituent Assembly of Belarus, convened on the basis of universal and equal suffrage.
