In a well-written paragraph, explain how the governments of two different countries are similar and different. Use at least two of the following terms in your response: autocracy, oligarchy, democracy, unitary, federation, confederation, parliamentary.

In Germany, the power is with the people (=it's a democracy) which are represented by the members of the parliament: it's a representative democracy. It's also a federation of 16 states. 

Iran, on the other hand is a theocracy: a country ruled by the members of the clergy. It can also be named an oligarchy: the power is with a few members of the society.
