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.

The Decembrist revolt was a failed coup d'état led by liberal military and political dissidents against the Russian Empire. It took place in Saint Petersburg on 26 December [O.S. 14 December] 1825, following the death of Emperor Alexander I.

Nicholas I was Emperor of Russia, King of Congress Poland, and Grand Duke of Finland from 1825 to 1855. He was the third son of Paul I and younger brother of his predecessor, Alexander I. Nicholas's thirty-year reign began with the failed Decembrist revolt. He is mainly remembered as a reactionary whose controversial reign was marked by geographical expansion, centralisation of administrative policies, and repression of dissent both in Russia and among its neighbors. Nicholas had a happy marriage that produced a large family, with all of their seven children surviving childhood.

Konstantin Pavlovich was a grand duke of Russia and the second son of Emperor Paul I and Sophie Dorothea of Württemberg. He was the heir-presumptive for most of his elder brother Alexander I's reign, but had secretly renounced his claim to the throne in 1823. For 25 days after the death of Alexander I, from 19 November (O.S.)/1 December 1825 to 14 December (O.S.)/26 December 1825 he was known as His Imperial Majesty Konstantin I Emperor and Sovereign of Russia, although he never reigned and never acceded to the throne. His younger brother Nicholas became tsar in 1825. The succession controversy became the pretext of the Decembrist revolt.
