The Decembrist revolt or the Decembrist uprising (Восстание декабристов) took place in Imperial Russia on December 14 (December 26 New Style), 1825. Russian army officers led about 3,000 soldiers in a protest against Nicholas I's assumption of the throne after his elder brother Constantine removed himself from the line of succession. Because these events occurred in December, the rebels were called the Decembrists (Dekabristy, Russian: Декабристы). This uprising took place in the Senate Square in St. Petersburg. In 1825, to mark the centenary of the event, it was renamed as Decembrist Square (Ploshchad' Dekabristov, Russian: Площадь Декабристов). The revolt was personally suppressed by Nicholas I of Russia.
