Example: The ancient Athenian democracy was a direct (pure) democracy. This meant that all citizens would come together and vote directly on issues. However, "all citizens" only included white men who owned property.

Below is a painting of the hall in which citizens met and voted on issues in ancient Athens.

Example: France has a republican government in which representatives are elected to represent the population as a whole.

Below is a video that describes the system that France uses in order to elect representatives for their government.

Example: Canada has a Constitutional Monarchy in which the Queen of England is the head of state, but the Canadians have their own Parliament.

Below is a video in which the queen of England explains her connection to Canada's government and how her power is limited in this Constitutional Monarchy

Example: Saudi Arabia is one of the few countries in the world that still uses a monarchy. The throne, and the power that comes with it, are passed down between the generations.

Below is the Saudi Arabia royal family tree, evidence that power is handed down through heredity.

Example: North Korea's government is in this form. It is also a communist state, and the only country left in today's world that is officially known as a dictatorship. It is currently under the tight control of Kim Jong-un, the grandson of North Korea's original dictator, Kim Il-sung, and son of Kim Jong-il. North Korea is not considered a monarchy, however, because the dictator of North Korea has always limited the people's freedoms, and uses the military to stay in power. Their government is sometimes described as totalitarian, but is also a dictatorship.

Below is a video describing how the North Korean government functions, and how it is a dictatorship (although it considers itself the most pure democracy in the world)
