The Duke of Cornwall. The Dukedom of Cornwall was the first dukedom created in the peerage of England. The dukedom is the last in the United Kingdom still associated with an actual duchy: the Duchy of Cornwall. The Prince of Wales became the 24th Duke of Cornwall on The Queen's accession to the throne, in 1952. When he was 21 in 1969, he became entitled to the full income of the Duchy and took over its management. The Duke of Cornwall is not, therefore, dependent on any public funding.
The Duchy of Cornwall is one of the largest and oldest landed estates in Britain. It was created in 1337 by Edward III for his son, Prince Edward (The Black Prince). A charter ruled that each future Duke of Cornwall would be the eldest surviving son of the monarch - and the Heir to The Throne of the United Kingdom.
