King Charles III (Charles Philip Arthur George) is King of the United Kingdom and 14 other Commonwealth realms. He acceded to the throne on 8 September 2022 upon the death of his mother, Queen Elizabeth II. As Duke of Cornwall and Duke of Rothesay from 1952 to his accession, he was the oldest and the longest-serving heir apparent in British history, and the longest-serving Prince of Wales, having held the title from 26 July 1958 until his accession. At 73, Charles was also the oldest person ever to assume the British throne. The record was previously held by King William IV at age 64.
Charles was born in Buckingham Palace, the first child of his mother and Philip, Duke of Edinburgh; he was the first grandchild of King George VI and his consort, Queen Elizabeth. He was educated at Cheam and Gordonstoun schools, both of which his father attended as a child. He later spent a year at the Timbertop campus of Geelong Grammar School in Victoria, Australia. After earning a Bachelor of Arts degree from the University of Cambridge, Charles served in the Royal Air Force and Royal Navy from 1971 to 1976.
