The Russian Revolution of 1905 was a massive wave of political and social upheaval that engulfed much of the Russian Empire. Some of them are anti-government, while others are directionless. These include terrorism, worker strikes, peasant riots and military mutinies. It led to the establishment of a limited constitutional monarchy, the State Duma of the Russian Empire, a multiparty system, and the Russian Constitution of 1906.
The Russian Revolution is the collective name for a series of revolutions in Russia in 1917 that destroyed the tsarist autocracy and led to the creation of the Soviet Union. The Tsar was deposed in the first February Revolution of 1917 (March in the Gregorian calendar; Russia was using the old Julian calendar at the time) and replaced by a Provisional Government. During the Second October Revolution, the Provisional Government was overthrown and replaced by a Bolshevik (Communist) government.
The February Revolution (March 1917) was a revolution centered in Petrograd (now St. Petersburg). Amid the chaos, members of the Reichstag, or Duma, took control of the country and formed the Russian Provisional Government. The army leadership decided they had no way to quell the revolution, and Russia’s last tsar, Tsar Nicholas II, abdicated.
Soviets (workers’ councils), led by a more radical socialist faction, initially allowed a provisional government to govern, but insisted on the privilege of influencing the government and controlling various militias. The February Revolution took place against the backdrop of severe military setbacks during World War I, which left much of the army in mutiny.
