The sudden death of Emperor Alexander I in December 1825 triggered a succession crisis. Alexander's heir-presumptive, Grand Duke Konstantin, had privately renounced the throne, leaving the unprepared Nicholas as heir. Much of the military had already sworn loyalty to Konstantin, creating confusion that liberal members of the Northern Society, a secret society seeking constitutional reform, sought to exploit.
On 26 December 1825, Northern Society members led roughly 3,000 troops into Senate Square in Saint Petersburg, aiming to block the loyalty-swearing ceremony for Nicholas I and force a regime change. The rebels were poorly coordinated due to internal indecision. After a standoff in which Nicholas's envoy Mikhail Miloradovich was assassinated, loyalist forces dispersed the rebels with heavy artillery fire.
Following the failed coup, five ringleaders were hanged and numerous participants were imprisoned or exiled to Siberia. The revolt prompted Nicholas I to intensify political repression and curtail liberal reform movements throughout his reign. The conspirators were collectively remembered as the Decembrists, and their uprising became a reference point for subsequent Russian revolutionary movements.
