Gweriniaeth is the Welsh term for "republic," a form of government where the country is considered a "public matter." In a republic, the power rests with the people, who elect representatives to make decisions on their behalf. This system contrasts with monarchies, where a king or queen holds power. In a Gweriniaeth, the rule of law is essential, ensuring that all citizens are treated equally and have rights protected by a constitution. Examples of modern republics include the United States and France, where democratic principles guide governance and civic participation is encouraged.
