Communism developed in Russia due to several factors. Peasants were dissatisfied with their poverty and small land holdings after emancipation from serfdom. Workers faced difficult conditions in factories with low pay and strikes being illegal. Tsar Nicholas II's autocratic rule was weak and unpopular as Russia fell behind other countries. Russia's losses and defeats in World War I further weakened the Tsar's position and support of the army. These conditions led to the Communist revolution in 1917 under the ideas of Karl Marx which established government control over resources and equality.
