form of social revolution arising in response to the mounting contradictions. This revolutionary change is the vehicle for fundamental society-wide changes and ultimately leads to the emergence of new economic systems. As a term, orthodox Marxism represents the methods of historical materialism and of dialectical materialism and not the normative aspects inherent to classical Marxism, without implying dogmatic adherence to the results of Marx's investigations. Leninism Leninism is the body of political theory developed by and named after the Russian revolutionary and later Soviet premier Vladimir Lenin for the democratic organisation of a revolutionary vanguard party and the achievement of a dictatorship of the proletariat as political prelude to the establishment of socialism. Leninism comprises socialist political and economic theories developed from Marxism as well as Lenin's interpretations of Marxist theory for practical application to the socio-political conditions of the agrarian early 20th-century Russian Empire.

This new and better society is called socialist society. The teachings about this society are called 'socialism'. The most important consequence of a Leninist-style theory of imperialism is the strategic need for workers in the industrialized countries to bloc or ally with the oppressed nations contained within their respective countries' colonies abroad to overthrow capitalism. This is the source of the slogan, which shows the Leninist conception that not only the proletariat—as is traditional to Marxism—are the sole revolutionary force, but all oppressed people: "Workers and Oppressed Peoples of the World, Unite!" The other distinguishing characteristic of Leninism is how it approaches the question of organization. Lenin believed that the traditional model of the social democratic parties of the time, a loose, multi-tendency organization, was inadequate for overthrowing the Tsarist regime in Russia. He proposed a cadre of professional
