minister of King Henry VII of England and author of a political allegory, The Tree of Commonwealth (1509).

In 1506 Dudley was “president of the king's council,” a small body of lawyers and fiscal administrators that helped reestablish the payment of feudal dues and of fines for lawbreaking. Charges that he defrauded the king—he amassed a fortune—and was otherwise guilty of corruption were not proved. In April 1509, just after the death of Henry VII, Dudley and Sir Richard Empson, another leader in the council, were arrested. Both were convicted of treason and were executed, largely because of Henry VIII's desire for popularity.

Dudley wrote The Tree of Commonwealth (ed. D.M. Brodie, 1948) while in the Tower. It is informed with the irony and wit of a great advocate. In the work Dudley insists on punctual performance of duties by all ranks of society, inveighs against administrative abuses sanctioned by law, and urges moderation in the use of royal powers.

Dudley was the father of John Dudley, duke of Northumberland (Northumberland, John Dudley, duke of, earl of Warwick, Viscount Lisle, Baron Lisle), who virtually ruled England from 1549 to 1553, during the minority of Edward VI, and who was executed for seeking to prevent the succession of Mary I. He was the grandfather of Robert Dudley, earl of Leicester (Leicester, Robert Dudley, earl of, Baron Denbigh), a favourite of Elizabeth I.
