A sovereign nation is a political entity that has the ultimate authority over its territory and is recognized as independent by other nations. This means it can create its own laws, govern its people, and manage its resources without external interference. Sovereign nations often have defined borders, a permanent population, and a government that exercises control over its affairs. Recognition by other countries and international organizations, such as the United Nations, is crucial for a nation to be considered sovereign. Sovereign nations can enter into treaties, engage in trade, and participate in global diplomacy, which helps maintain their independence and stability in the international community.
