Republics differ from monarchies in several ways:

1. Governance: In a monarchy, power is held by a single individual, usually a king or queen, who inherits the position based on their family lineage. In contrast, a republic is a form of government in which power is held by the people or their elected representatives.

2. Leadership: In a monarchy, the leader is usually a hereditary monarch who holds absolute or limited powers. Their authority is often derived from divine right or inherited status. In a republic, leadership is based on the will of the people, and elected officials are chosen to represent their interests.

3. Decision-making: Monarchies tend to have centralized decision-making, where the monarch has the final say on matters of governance. In a republic, decision-making is more decentralized, with power distributed among multiple branches of government and elected representatives.

4. Term limits: Monarchs in a hereditary monarchy typically have no term limits, as their position is often for life or until they abdicate. In a republic, elected officials generally have term limits, ensuring a regular turnover of leadership and preventing the concentration of power in one person or group.

5. Accountability: Monarchs are not directly accountable to the people, as their power is often seen as derived from divine right or tradition. In a republic, elected officials are accountable to the citizens, as they can be voted out of office if they fail to fulfill their responsibilities or meet the expectations of the people.

These are general differences, and the specific characteristics of republics and monarchies can vary depending on the country and its political system.
