Lenin played an important role in the Russian revolution. When Japan defeated Russia in 1905, it was a great insult to the people of Russia. It was due to the worst administration of the Tsars. The people started rebellions against the Tsars. Thousands of factory workers and peasants fought with weapons. At this juncture, Lenin, the leader of the Bolsheviks Labour Party guided the workers and peasant in revolution against the Tsars. The working class engaged in more and more agitations. The last Russian Tsar Nicholas II was unable to control the agitations and deserted the country. As a result, Mansheviks party gained the power of Russia. Lenin who was in exile came back to his countiy. He assured the people a good government. The people responded whole heartedly to this. He declared Russia a Socialist Republic in 1917. He became the President of Russia.
