The title of Earl of Northumberland has been created several times in the Peerage of England and of Great Britain, succeeding the title Earl of Northumbria. Its most famous holders are the House of Percy, who were the most powerful noble family in Northern England for much of the Middle Ages. The heirs of the Percys, via a female line, were ultimately made Duke of Northumberland in 1766, and continue to hold the earldom as a subsidiary title.
