A more thorough explanation:

Definition: Aristodemocracy is a type of government that combines both democratic and aristocratic elements. In this form of government, power is shared between the nobility or the more powerful group and the rest of the people.

Example: The ancient Greek city-state of Athens is an example of an aristodemocracy. In Athens, the nobility or the aristocrats held significant power, but the common people also had a say in the government through the democratic institutions such as the Assembly and the Council of 500.

Explanation: In Athens, the aristocrats were the wealthy and influential citizens who held important positions in the government. However, the common people also had a voice in the government through the democratic institutions. This sharing of power between the aristocrats and the common people is an example of an aristodemocracy.
