"The Commonwealth of Nations" is a phrase that refers to a group of 54 countries, mostly former British colonies or territories, that share cultural, historical, and political ties. It was formerly called the British Commonwealth, and other synonyms include the Commonwealth, the Commonwealth Realms, and the British Commonwealth of Nations. Some people also use the term "the Commonwealth Countries" or simply "the Commonwealth." The organization aims to promote cooperation, democracy, and human rights among its members. It also serves as a platform for trade, education, and development initiatives. The Queen of England is the symbolic head of the Commonwealth, but the organization's operations are overseen by a secretary-general and a number of committees and agencies.
