Decembrist Revolt Against Nicholas I

Date: December 26, 1825 • Location: Moscow, Russia

Imperial Russian Army officers led about 3,000 soldiers in protest against Nicholas I's assumption of the throne after his elder brother Konstantin removed himself from the line of succession.

The Imperial Russian Army was the army of the Russian Empire, active from 1721 until the Russian Revolution of 1917. It was organized into a standing army and a state militia. The standing army consisted of regular troops and two forces that served on separate regulations: the Cossack troops and the Muslim troops.
