Vladimir Lenin rose to power in Russia when he and his associate Leon Trotsky overthrew the nation's provisional government during the October Revolution. The provisional government had been in place since Tsar Nicholas II was removed from power during the February Revolution earlier that year. Many Russians were ready to embrace Lenin's radical ideas because they were poor and tired as a result of the first world war.
Lenin first became acquainted with the radical ideas that formed Leninism during his time at college. After college, he traveled through Europe, established ties with Karl Marx and tried to convince people that World War I should be a worldwide revolution for the proletariat or working class.
Lenin was only in power for seven years. During that time, he legalized homosexuality and abortion and lead the Bolshevik party to domination. Eventually, he realized that he could not realistically run a completely socialist country so he created the New Economic Policy, a policy that allowed more private enterprise.
Lenin was committed to the ideals of equality and social justice, but he was also a ruthless leader who was willing to crush the opposition. After his death, he was succeeded by Stalin, a man who he opposed.
