A democracy is a system of government in which power is vested in the people, typically through elected representatives, whereas a republic emphasizes the rule of law and the protection of individual rights. In a democracy, majority rule may dominate decision-making, while a republic safeguards minority rights against potential tyranny of the majority. Both systems promote political participation and civic engagement, but they differ in how they balance freedom and authority. A republic usually includes a constitution that establishes frameworks for governance and rights, ensuring that government powers are limited and accountable to citizens.
