Extreme government-changing activity in the Russian Empire began with the Decembrist Revolt of 1825, and although serfdom was removed in 1861, its removal was achieved on terms unfavorable to the peasants (poor agricultural workers) and served to encourage changers (revolutionaries). A parliament (legislative assembly)—the State Duma—was created in 1906 after the Russian Revolution of 1905, but the Tsar protested people trying to move from absolute to constitutional monarchy. Rebellion continued and was aggravated during World War I by failure and food shortages in popular cities.
