Leninism -
the political and economic theories of Lenin which provided the guiding doctrine of the Soviet Union; the modification of Marxism by Lenin stressed that imperialism is the highest form of capitalism (which shifts the struggle from developed to underdeveloped countries)
Leninism is a political theory and practice of the dictatorship of the proletariat, led by a revolutionary vanguard party. Developed by and named after Russian revolutionary and politician Vladimir Lenin, Leninism comprises political and socialist economic theories, developed from Marxism, and Lenin's interpretations of Marxist theory within the agrarian Russian Empire of the early 20th century. Leninism reversed Marx’s order of economics over politics, allowing for a political revolution led by a vanguard party of professional revolutionaries rather than a spontaneous uprising of the working class as predicted by Karl Marx.
