The Monarchy of the United Kingdom has a long history dating back to the early medieval period. The current monarch is Queen Elizabeth II, who ascended to the throne in 1952. The monarchy's role in the UK is largely ceremonial, with the monarch serving as the head of state and representing the country both domestically and internationally. The monarchy has evolved over time, with key moments including the Magna Carta in 1215 limiting the powers of the monarch, the Glorious Revolution of 1688 establishing a constitutional monarchy, and various reforms in the 20th century to modernize and streamline the institution. The royal family continues to play a significant role in UK culture and society, with members undertaking official duties and charitable work.
