Briefly promoted to a principality in 1398 by King Richard II, who titled himself "Prince of Chester", it was reduced to an earldom again in 1399 by King Henry IV. Whereas the Sovereign's eldest son is born Duke of Cornwall, he must be made or created Earl of Chester (and Prince of Wales; see the Prince Henry's Charter Case (1611) ). Prince Charles was created Earl of Chester on 26 July 1958, when he was also made Prince of Wales.
The independent palatinate jurisdiction of Chester survived until the time of King Henry VIII (1536), when the earldom was brought more directly under the control of the Crown. The palatinate courts of Great Sessions and Exchequer survived until the reforms of 1830.
