A queen is a female monarch who typically rules a kingdom or territory. She may inherit her position through birthright or be appointed through marriage to a king. Queens often have significant political power, although their roles can vary widely depending on the country's laws and traditions. In many cultures, queens are also seen as symbols of grace and leadership. They may engage in charitable work and represent their nation at official events. Famous historical queens include Queen Elizabeth I of England and Cleopatra of Egypt, both known for their influence and legacy.
