The October Revolution in Russia in 1917 signified the collapse of Tsarist Russia and the establishment of a regime by the Bolsheviks and the leader of the Communist Party, Lenin. The main reason, among others, was the dissatisfaction of peasants and workers due to large class differences. The dissatisfaction of workers and peasants was preceded by several wars that Russia led and lost all, but the war with Turkey. Peasants barely survived in unreformed economic agricultural conditions. Workers fought for bigger rights in factories, for shortening working hours, but primacy was in waging wars, rather than dealing with economic issues and dissatisfaction of workers and peasants. Also, Emperor Nicholas spent more time dealing with his own family than on state issues. All this led to the general dissatisfaction of the people and the October Revolution.
