What term refers to the principle of "the people rule"?

The principle of "the people rule" is best represented by the term democracy. In a democracy, the authority and governance are derived from the consent of the governed, meaning that power is vested in the people. This is typically exercised directly by the populace or through elected representatives who act on behalf of the citizens.

In contrast, the other terms refer to different systems of governance where the people do not have the same level of power. A republic, while it involves elected representatives, can exist within a broader democratic framework, but it emphasizes the rule of law and rights of individuals. Autocracy signifies a system where a single individual holds ultimate power, limiting the role and influence of the people. An oligarchy indicates governance by a small group of individuals, which also restricts the participation of the general populace in decision-making. Hence, democracy stands out as the term that embodies the concept that the authority of governance originates from the people.
