Oligarchy:
1. Government system ruled and controlled by a small group of privileged people.
2. Citizens have a very limited role.
3. No individual freedoms are given.
4. Unlimited Government- Rulers can do anything they want.
Democracy:
1. Everyone in power is elected by the people.
2. Citizens have a very active role and participation in the government.
3. Individual freedoms are given.
4. Limited Government- People who make the laws also have to follow the law.
I hope this helps! :)
