94–1917), was unable to prevent the events of the Russian Revolution of 1905, triggered by the unsuccessful Russo-Japanese War and the demonstration incident known as Bloody Sunday. The uprising was put down, but the government was forced to concede major reforms, including granting the freedoms of speech and assembly, the legalization of political parties, and the creation of an elected legislative body, the State Duma of the Russian Empire. Migration to Siberia increased rapidly in the early 20th century, particularly during the Stolypin agrarian reform. Between 1906 and 1914 more than four million settlers arrived in that region.
In 1914 Russia entered World War I in response to Austria-Hungary's declaration of war on Russia's ally Serbia, and fought across multiple fronts while isolated from its Triple Entente allies. In 1916 the Brusilov Offensive of the Russian Army almost completely destroyed the military of Austria-Hungary. However, the already-existing public distrust of the regime was deepened by the rising costs of war, high casualties, and rumors of corruption and treason. All this formed the climate for the Russian Revolution of 1917, carried out in two major acts.
The February Revolution forced Nicholas II to abdicate; he and his family were imprisoned and later executed during the Russian Civil War. The monarchy was replaced by a shaky coalition of political parties that declared itself the Provisional Government. An alternative socialist establishment existed alongside, the Petrograd Soviet, wielding power through the democratically elected councils of workers and peasants, called Soviets. The rule of the new authorities only aggravated the crisis in the country, instead of resolving it. Eventually, the October Revolution, led by Bolshevik leader Vladimir Lenin, overthrew the Provisional Government and created the world’s first socialist state.
