The document discusses the Commonwealth of Nations, a voluntary association of 53 member states comprised mostly of former British colonies. It began as the British Commonwealth of Nations in the early 20th century and was established in its current form in 1949. The Queen serves as head of the Commonwealth. While some members recognize the Queen as their head of state, most are republics. The Commonwealth aims to promote democracy, human rights, and economic cooperation among its diverse and geographically dispersed members.
