POLITICAL IDEOLOGIES Socialism is an economic system characterized by social ownership of the means of production and co-operative management of the economy. "Social ownership" may refer to cooperative enterprises, common ownership, state ownership, or citizen ownership of equity.

Communism is a revolutionary socialist movement to create a classless, moneyless and stateless social order structured upon common ownership of the means of production, as well as a social, political and economic ideology that aims at the establishment of this social order. This movement, in its Marxist–Leninist interpretations, significantly influenced the history of the 20th century, which saw intense rivalry between the "socialist world" (socialist states ruled by communist parties) and the "western world" (countries with capitalist economies).

Capitalism is an economic system based on the private ownership of the means of production, with the goal of making a profit. Central elements of capitalism include capital accumulation, competitive markets, and a price system.

Anarchism is often defined as a political philosophy which holds the state to be undesirable, unnecessary, or harmful. However, others argue that while anti-statism is central, it is inadequate to define anarchism. Therefore, they argue instead that anarchism entails opposing authority or hierarchical organization in the conduct of human relations, including, but not limited to, the state system.

Fascism is a form of radical authoritarian nationalism that came to prominence in mid-20th century Europe. Fascists seek to unify their nation through a totalitarian state that promotes the mass mobilization of the national community, relying on a vanguard party to initiate a revolution to organize the nation on fascist principles. Hostile to democracy, liberalism, socialism, and communism, fascist movements share certain common features, including the veneration of the state, a devotion to a strong leader, and an emphasis on ultra nationalism, ethnocentrism, and militarism. Fascism views political violence, war, and imperialism as a means to achieve national rejuvenation

Nazism (German: Nationalsozialismus) is the ideology of the Nazi Party in Germany and related movements elsewhere. It is a variety of fascism that incorporates biological racism and antisemitism. Nazism developed from the influences of pan-Germanism, the far-right racist Völkisch German nationalist movement and the anti- communist Freikorps paramilitary culture which fought against the communists in post-World War I Germany. It was designed to draw workers away from communism and into völkisch nationalism.
