Decembrist revolt

The Decembrist revolt (Russian: Восстание декабристов, romanized: Vosstaniye dekabristov, lit. 'Uprising of the Decembrists') 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. Alexander's brother and heir-presumptive Grand Duke Konstantin Pavlovich privately renounced his claim to the throne two years prior to Alexander's sudden death on 1 December [O.S. 19 November] 1825. The next in the line of succession therefore was younger brother Nicholas, who would ascend the throne as Emperor Nicholas I. Neither the Russian government nor the general public were initially aware of Konstantin's renunciation, and as a result, parts of the military took a premature oath of loyalty to Konstantin. A general swearing of loyalty to the true emperor Nicholas was scheduled for 26 December [O.S. 14 December] 1825 in Senate Square, Saint Petersburg. In the midst of this confusing transition into Nicholas' reign, the Northern Society, a secret society of liberal revolutionaries, nobles, and military officials, organized a conspiracy to replace the Russian Empire's autocratic regime with a constitutional monarchy. To seize control of the government and implement a regime change, it sought to convince the military that Nicholas was usurping the throne from Konstantin. On 26 December, Northern Society members led a force of approximately 3,000 troops into Senate Square to prevent the loyalty-swearing ceremony and to rally additional soldiers and officers to their cause. This group of rebels, although disorganized due to indecision and dissension among its leaders, confronted troops loyal to Nicholas outside the Senate building in the presence of a large civilian crowd. A standoff ensued, during which Nicholas' envoy, Mikhail Miloradovich, was assassinated. The loyalists eventually opened fire with heavy artillery, scattering the rebels....
