The Decembrist Revolt Erupted in Russia

Liberal officers marched 3,000 troops into a St. Petersburg square to defy a new tsar — and Russia's first modern revolution collapsed by nightfall.

On December 26, 1825 (December 14 on the Julian calendar then used in Russia), a group of reform-minded army officers led roughly 3,000 soldiers into Senate Square in St. Petersburg. Many had served in the wars against Napoleon and returned home admiring the constitutional governments they had seen in Western Europe.

The rebels refused to swear allegiance to Nicholas I, exploiting confusion over the succession after the death of Tsar Alexander I. Drawn largely from the secret Northern Society, they wanted to replace autocracy with a constitution and to abolish serfdom.

Disorganized and indecisive, the rebels stood exposed in the square while loyal forces gathered around them.

Nicholas eventually ordered artillery to fire into the crowd, scattering the uprising within a day and leaving dozens dead. Five leaders were later hanged and scores were exiled to Siberia. Though it failed, the revolt is remembered as the first open rupture between the Russian state and a reform movement within its own nobility.
