Born Charles Philip Arthur George on 14 November 1948, His Majesty King Charles III is the eldest son of the late Queen Elizabeth II and Prince Philip, the Duke of Edinburgh. He became heir apparent at the age of three, when Elizabeth acceded to the throne in 1952. As heir apparent, Charles adopted, as tradition dictated by the Charter of King Edward III, the titles Duke of Cornwall and, in Scottish peerage, Duke of Rothesay, Earl of Carrick, Baron Renfrew, Lord of the Isles, and Prince and Great Steward of Scotland. As a nine-year-old, he was given two further titles: Prince of Wales and Earl of Chester. Charles acceded to the throne on 8 September 2022.
