The Decembrists were a group of Russian army officers who led a failed uprising against the autocratic rule of Tsar Nicholas I on December 14, 1825. They sought to establish a constitutional monarchy and promote civil liberties, inspired by the ideas of the French Revolution and European liberal movements. Their revolt took place in St. Petersburg and was quickly suppressed by loyalist forces. Following the uprising, many Decembrists were arrested, executed, or exiled to remote regions of Siberia. Their actions sparked a wave of political thought in Russia, influencing future generations of reformers and revolutionaries, and they are often seen as early advocates for change in Russian society.
