The Russian Revolution of 1905, also known as the First Russian Revolution, was a revolution in the Russian Empire which began on 22 January 1905 and led to the establishment of a constitutional monarchy under the Russian Constitution of 1906, the country's first. The revolution was characterized by mass political and social unrest including worker strikes, peasant revolts, and military mutinies directed against Tsar Nicholas II and the autocracy, who were forced to establish the State Duma legislative assembly and grant certain rights, though both were later undermined.
In the years leading up to the revolution, impoverished peasants had become increasingly angered by repression from their landlords and the continuation of semi-feudal relations. Further discontent grew due to mounting Russian losses in the Russo-Japanese War, poor conditions for workers, and urban unemployment. On 22 January [O.S. 9 January] 1905, known as "Bloody Sunday," a peaceful procession of workers, led by Georgy Gapon, was fired on by guards outside the tsar's Winter Palace in Saint Petersburg. Widespread demonstrations and traditional strikes spread all over the empire and were brutally repressed by the tsar's troops. In June, sailors on the battleship Potemkin undertook a mutiny, and in October, a strike by railway workers turned into a general strike in Saint Petersburg and Moscow. The striking urban workers established councils, including the inaugural St. Petersburg Soviet of Workers' Deputies, in order to debate their course of action. The influence of revolutionary parties, in particular the Socialist Revolutionary Party and Russian Social Democratic Labour Party, quickly escalated. At the same time, the reactionary pro-monarchist Black Hundreds began attacks on intellectuals, revolutionaries, and the Jewish population.
