**Oligarchies and monarchies had a ruling class that presided over the people while democracies relied entirely on the people.**
This statement reflects the fundamental differences in governance structures between oligarchies, monarchies, and democracies. In oligarchies and monarchies, power is held by a small group or a singular ruler, while in democracies, the power is derived from the people and their voting rights.
