Dud´ley, Sir Edmund, born 1462, executed 1510, noted in English history as an instrument of Henry VII in the arbitrary acts of extortion by the revival of obsolete statutes and other unjust measures practised during the latter years of his reign. On the accession of Henry VIII he was arrested for high treason, and perished on the scaffold with his associate Sir Richard Empson.
Dudley, Lord Guildford, son of John, Duke of Northumberland, was married in 1553 to Lady Jane Grey, whose claim to the throne the duke intended to assert on the death of Edward VI. On the failure of the plot Lord Guildford was condemned to death, but the sentence was not carried into effect till the insurrection of Wyatt induced Mary to order his immediate execution (1554).
Dudley, John, Duke of Northumberland, son of Sir Edmund Dudley, minister of Henry VII, was born in 1502, beheaded 1553. He was left by Henry VIII one of the executors named in his will, as a kind of joint-regent during the minority of Edward VI. Under that prince he manifested the most insatiable ambition, and obtained vast accessions of honours, power, and emoluments. The illness of the king, over whom he had gained complete ascendency, aroused his fears, and he endeavoured to strengthen his interest by marrying his son Lord Guildford Dudley to Lady Jane Grey, descended from the younger sister of Henry VIII, and persuaded Edward to settle the crown on his kinswoman by will, to the exclusion of his two sisters, the Princesses Mary and Elizabeth. The attempt to place Lady Jane Grey on the throne failed, and many of the conspirators were executed.
