C. ARISTOTLE believed that the best government was a mixture of oligarchy and democracy.
A combination of oligarchy and democracy under law is known as constitutional government.
Oligarcy is a government by the few. This is a power structure where the power rests on a small number of people. They might be distinguished by royalty, weath, family ties, religious or military control.
Democracy is a government by the many. Where all the people of the state or polity are involved in decision making. The people will vote their representatives to a parliament or similar assembly to speak in their behalf.
