Charles, Prince of Wales (Charles Philip Arthur George; born 14 November 1948) is the eldest child and heir apparent of Queen Elizabeth II. Known alternatively in Cornwall as Duke of Cornwall and in Scotland as Duke of Rothesay, he is the longest-serving heir apparent in British history, having held the position since 1952. He is also the oldest person to be next in line to the throne since Sophia of Hanover (the heir presumptive to Queen Anne), who died in 1714 at the age of 83. 

Charles was born at Buckingham Palace as the first grandchild of King George VI and Queen Elizabeth. He was educated at Cheam and Gordonstoun Schools, which his father, Prince Philip, Duke of Edinburgh, had attended as a child, as well as the Timbertop campus of Geelong Grammar School in Victoria, Australia. After earning a bachelor of arts degree from Trinity College, Cambridge, Charles served in the Royal Navy from 1971 to 1976. 

In 1981, he married Lady Diana Spencer and they had two sons: Prince William (born 1982), later to become Duke of Cambridge, and Prince Harry (born 1984). In 1996, the couple divorced, following well-publicised extramarital affairs. Diana died in a car crash in Paris the following year. In 2005, Charles married Camilla Parker Bowles.
