At birth, as the son of the Duchess and Duke of Edinburgh, he was given the title His Highness the Duke of Edinburgh. After his mother's accession to the throne, he became Duke of Cornwall and Duke of Rothesay.
On July 26, 1958, the Queen, by decree, added to the titles of her eldest son the titles of Earl of Chester and Prince of Wales. There is an incident associated with the latter. On July 1, 1969, as the 21-year-old Charles was giving a speech at Caernarfon Castle in Wales during a ceremony to accept the title, a group of youths threw eggs at the Queen's carriage and a bomb exploded. The person responsible for the explosion was John Bernard Jenkis, a Welsh nationalist and member of the British Army. He was arrested later that year. Jenkis died on December 17, 2020.
