I suspect many people think that Charles is still Duke of Cornwall - no, that is now William.
The Duchy was first created centuries ago, partly to give the heir to the throne a private income until he succeeded his father, (making it less likely that he would hasten his father's demise to get his hands on the treasury) and partly to give him something responsible to do and to cut his management teeth on, and get some experience of the problems of running a large estate and making it pay, before he was let loose on a whole kingdom.
