A totalitarian government, also called an autocracy, is defined by an extremely centralized government in which one person, or one group, wields complete and unchallenged control over the rest of the state. Totalitarian governments are increasingly uncommon around the world, but certainly far from nonexistent.

The Italian state under Mussolini was a prominent examples of Fascism. In a fascist government, liberal democracy is rejected as being too weak, and a system of totalitarian control over the media and the population is instituted. Fascist philosophy believes that the technological advancements of the early twentieth century rendered the distinction between civilian and military combatant obsolete. In a fascist state, the civilian population is mobilized as part of the war effort and is under complete control of the government. Violent nationalism is an important part of fascist ideology.

A system of government ruled by religious leaders and where law is established according to religious codes is called a theocracy. 

The United Nations is an international body designed to prevent warfare and represent the collective interests of all the nations of humanity, at least in theory. It was formed after the end of World War Two, in 1945. The League of Nations (the first attempt at such an international organization) was formed in 1918, at the end of World War One, but suffered from a lack of American participation and subsequent ineffectiveness.

Apartheid was a social policy of racial segregation in South Africa from 1948 until the early 1990s. It was enforced by the government, which reduced the economic and political rights of black people in the country.

Communism is an economic system where all property and the means of production are owned by the state. One of the driving forces of capitalism, ownership of private property, is completely eliminated in favor of (in theory) fairly distributing all property and economic goods.

A theocracy is a system of government ruled by a priest, or other religious figure, who claims to interpret the word of god when establishing laws and rules in the country. In a theocracy, the government is essentially a conduit for religious belief.

Despotism is another word for Autocracy. A Despot is an autocratic ruler, or a tyrant: someone who rules with absolute authority and who cannot be questioned or removed from power by legal means.

The economic and political system of feudalism arose after the fall of the Roman Empire. In the political and military vacuum created by Rome’s fall from power, there was a large number of people and groups contending for power. It was a time of brutal violence and great instability. To try to create stability, various rulers began to offer portions of land, or “fiefdoms,” to lesser rules, who could then have serfs work the land to provide food and income. The system of feudalism was effective because it promoted stability in a very violent time and offered protection in exchange for loyalty and subservience.

The Supremacy Clause of the United States Constitution states that the Constitution should be considered as the supreme law of the land, and that everyone must respect the rules and laws contained within. This might seem obvious and unnecessary to us now, but it is important to remember that when the Constitution was written there was no guarantee as to how it would be received or whether the people would unquestionably follow it.
