A nation is a large group of people who share a common identity, often defined by shared culture, language, history, and values. Nations typically have defined geographical boundaries and a governing body that creates and enforces laws. Examples of nations include France, Japan, and Brazil. Nations can be made up of various ethnic groups and may contain multiple languages and traditions. They often engage in international relations, trade, and diplomacy with other nations. The concept of a nation is central to discussions about nationalism, sovereignty, and citizenship.
