A political regime is a set of political structures that make up a state. A political regime may also be known as a form of government, a state system, or a political system. The term political regime may also sometimes refer to a specific ruler or set of rulers within a political system.

There are many different types of political regime in the modern world, and many more have existed historically. These range from the directly-democratic political regime of Anarchism to totalitarian regimes such as Military Dictatorships or Fascism.

The political regime that Americans are most familiar with is Representative Democracy. This is a political regime in which representatives are directly elected by the citizenry, and these representatives then make political decisions for the populace, with the assumption that their decisions will reflect the general will of the Republic. This can be compared to a Direct Democracy, in which the citizenry directly votes on all issues of importance.

The Republic is probably the most common form of political regime in the world, although it takes many different forms. Republics are often denoted in the official name of the state, and often include a modifier to convey some sort of philosophical ideal the political regime holds. For example, Guyana is known as a Cooperative Republic, Vietnam is known as a Socialist Republic, Sri Lanka is known as a Democratic Socialist Republic, China is known as a People’s Republic, and North Korea is known as a Democratic People’s Republic. A number of Republics try to show the fact that they are actually made up of smaller, semi-autonomous parts. The United States of America, for example, says very clearly that its political regime is that of a group of united state entities. Both Nigeria and Germany also convey this idea, by calling themselves Federal Republics.

Some political regimes are leftovers from a bygone age. Luxembourg, for example, is officially known as a grand duchy, dating back to a time when it was a part of the Netherlands as a Dutch dominion.

A unique political regime was created as the British Empire began to let go of its holdings in the world, wherein newly formed democracies labeled themselves as Commonwealths. Although completely independent from the United Kingdom, these Commonwealths nonetheless retained the sovereign of England as an honorary head of state, and kept close contact with the United Kingdom.

There are a number of types of political regime that exist more in theory than anywhere in the world. The strict Meritocracy, for example, where leaders are chosen based on their ability to lead, not necessarily through election by a populace, but by some form of standardized testing. Or a Corporatocracy, a popular political regime in science fiction, in which corporations rule their own sovereign states.

Other types of political regime are rare in the modern world, but still exist in pockets. Theocracies, for example, such as the government of Tibet in exile, or of Vatican City, where a religious figure is also granted secular power of the government.

Generally, for a political regime to survive, it needs to either have a strong mandate from its people, or a strong military might to suppress dissent from its populace. Political regimes that for whatever reason don’t fulfill the populace, such as the Communist political regimes of many Eastern Bloc countries, eventually give way to new political regimes. In the end, it’s impossible to say if any one political regime is better or worse than another, and the rainbow of political regimes seems to be constantly shifting and evolving.
