A republic is a form of government in which the country is considered a "public matter" and not the private concern or property of the rulers. In a republic, the country is considered a "res publica", which means "public affair" or "public thing". This form of government is based on the idea that power is vested in the people, who exercise their power through elected representatives.
Some examples of republics include the United States, France, Germany, India, and Brazil. These countries have elected representatives, a separation of powers, and a commitment to upholding the rule of law and individual rights.
