List of countries by system of government

This is a list of the countries by system of government.

The list is color-coded according to the type of government, for example: yellow represents a Republic with an executive head of state, and pink is a constitutional monarchy with a ceremonial head of state. The color-coding also appears on the following map, representing the same government categories. The legend of what the different colors represent are found at the end of the article.

Note that Afghanistan, Iran, Pakistan, the Gambia and Mauritania are Islamic Republics.
