Saint Petersburg Soviet in the context of "Russian Revolution of 1905"

Lev Davidovich Trotsky (né Bronstein; 7 November [O.S. 26 October] 1879 – 21 August 1940), better known as Leon Trotsky, was a Russian revolutionary, Soviet politician and political theorist. He was a key figure in the 1905 Revolution, October Revolution of 1917, Russian Civil War, and the establishment of the Soviet Union, from which he was exiled in 1929 before his assassination in 1940. Trotsky and Vladimir Lenin were widely considered the two most prominent figures in the Soviet state from 1917 until Lenin's death in 1924. Ideologically a Marxist and a Leninist, Trotsky's ideas inspired a school of Marxism known as Trotskyism.

Trotsky joined the Russian Social Democratic Labour Party in 1898, being arrested and exiled to Siberia for his activities. In 1902 he escaped to London, where he met Lenin. Trotsky initially sided with the Mensheviks against Lenin's Bolsheviks in the party's 1903 schism, but declared himself non-factional in 1904. During the 1905 Revolution, Trotsky was elected chairman of the Saint Petersburg Soviet. He was again exiled to Siberia, but escaped in 1907 and lived abroad. After the February Revolution of 1917, Trotsky joined the Bolsheviks and was elected chairman of the Petrograd Soviet. He helped to lead the October Revolution, and as the People's Commissar for Foreign Affairs negotiated the Treaty of Brest-Litovsk, by which Russia withdrew from World War I. He served as People's Commissar for Military Affairs from 1918 to 1925, during which he built the Red Army and led it to victory in the civil war. In 1922 Lenin formed a bloc with Trotsky against the growing Soviet bureaucracy and proposed that he should become a deputy premier, but Trotsky declined. Beginning in 1923, Trotsky led the party's Left Opposition faction, which supported greater levels of industrialisation, voluntary collectivisation and party democratisation in a shared framework with the New Economic Policy.

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 Labor Party, quickly escalated. At the same time, the reactionary pro-monarchist Black Hundreds began attacks on intellectuals, revolutionaries, and the Jewish population.
