The "Queen of Great Britain" refers to the reigning monarch of the United Kingdom, which includes England, Scotland, Wales, and Northern Ireland. The role of the queen is largely ceremonial, representing the nation at official events and performing duties such as the State Opening of Parliament. The current queen, Queen Elizabeth II, ascended to the throne in 1952 and was the longest-reigning monarch in British history. The monarchy is a constitutional institution, meaning the queen's powers are limited by law and Parliament. The royal family, including members like Prince Charles and Prince William, plays a significant role in British culture and public life, often engaging in charitable work and community events.
