Democracy

A system where the people have the power to vote for a president. Usually this system has a constitution which the people vote on what should go in it.

Communism

Communism takes many shapes and forms. You have Leninism, Maoism, Marxism, Stalinism, and anarcho-communism. This ideology can go many ways depending on how you run it.

Fascism

Fascism is a far-right, authoritarian political ideology that prioritizes the nation, or race, above the individual. It rejects liberalism, democracy, and socialism, seeking to unite society through strict social hierarchy, militarism, and often, a powerful, dictatorial leader. Usually having this type a government is a terrible idea because people always find a way to revolt if the system is too brutal.

Parliamentary Government

It's basically when a kingdom can't choose between Monarchy and democracy, so they mix the two together. Basically the king or queen are just figure heads of the country. The only real power they get is veto power, but that's about it. The ones who have the most amount of power are the parliament and the Prime Minister of the country, along with the people of the country.

Imperialism

Imperialism is the state policy, practice, or advocacy of extending a nation's power and dominion. This is typically achieved through direct territorial acquisition or by exerting indirect control over the political, economic, and cultural life of other regions. Usually the military has the most power and the king/queen or emperor/empress either approve of the expansion request or deny the expansion request. It's basically fascism with a different name.

Tribalism

Basically a tribal ruling system. Chiefs can be either male or female, and usually leadership is either inherited or fought for via challenge and whoever wins becomes the leader of the tribe.
