Here’s what we know about the British royal family’s line of succession. King Charles Born: November 14, 1948 What you need to know: First in the line of succession, Charles was Britain’s longest-serving monarch-in-waiting. He has been the heir apparent since the age of 3. As chairman of The Prince’s Trust and the Royal Shakespeare Company, and chairman or patron of more than 400 charities, the Prince of Wales is the first royal heir to earn a university degree. More Key Relatives: Diana, Princess of Wales, to whom he was married from 1981 to 1996. Together they had two children: Princes William and Harry. Diana died in 1997 after a car accident in Paris, along with his friend Dodi Fayed and driver Henri Paul. In 2005, the Prince of Wales married Camilla, Duchess of Cornwall. Prince William, Duke of Cambridge Born: June 21, 1982 What you need to know: Prince William, next in line to the throne after his father Charles, has achieved the highest educational degree – Masmer of Arta – of any member of the royal family. He served in the military from 2006 to 2013, participating in more than 150 helicopter search and rescue operations. More key relatives: Catherine, Duchess of Cambridge, whom he married in 2011. The couple have three children together: Prince George, 9; Princess Charlotte, 7; and Prince Louis, 4. The family live at Adelaide Cottage, a four-bedroom property in the grounds of Windsor Castle, Berkshire, about 25 miles from London. The Cambridges’ London residence, Kensington Palace, will remain the family’s primary residence, however, a royal source told CNN in August. Prince George of Cambridge Born: July 22, 2013 What to know: When Prince George arrived, he became third in line to inherit the throne. If he becomes king after the reigns of his grandfather Prince Charles and father Prince William, George will be the 43rd monarch since William the Conqueror. For now, though, he’s continuing his education: George currently attends Lambrook School near Windsor alongside his younger sister, Charlotte, and younger brother, Louis. See more here.
