the reign of Henry IV.;
and was for a short time at the head of the government, leading an
unsuccessful expedition into France in 1412. When Henry V., however,
became king in 1413 no serious dissensions took place between the
brothers, and as a member of the royal council Clarence took part in the
preparations for the French war. He was with the English king at
Harfleur, but not at Agincourt, and shared in the expedition of 1417
into Normandy, during which he led the assault on Caen, and
distinguished himself as a soldier in other similar undertakings. When
Henry V. returned to England in 1421, the duke remained in France as his
lieutenant, and was killed at Beauge whilst rashly attacking the French
and their Scottish allies on the 22nd of March 1421. He left no
legitimate issue, and the title again became extinct.

GEORGE, duke of Clarence (1449-1478), younger son of Richard, duke of
York, by his wife Cicely, daughter of Ralph Neville, 1st earl of
Westmorland, was born in Dublin on the 21st of October 1449. Soon after
his elder brother became king as Edward IV. in March 1461, he was
created duke of Clarence, and his youth was no bar to his appointment as
lord-lieutenant of Ireland in the following year. Having been mentioned

earl of Warwick, and in July 1469 was married at Calais to the earl's
elder daughter Isabella. With his father-in-law he then acted in a
disloyal manner towards the king. Both supported the rebels in the north
of England, and when their treachery was discovered Clarence was
deprived of his office as lord-lieutenant and fled to France. Returning
to England with Warwick in September 1470, he witnessed the restoration
of Henry VI., when the crown was settled upon himself in case the male
line of Henry's family became extinct. The good understanding, however,
between Warwick and his son-in-law was not lasting, and Clarence was
soon secretly reconciled with Edward. The public reconciliation between
the brothers took place when the king was besieging Warwick in Coventry,
and Clarence then fought for the Yorkists at Barnet and Tewkesbury.
After Warwick's death in April 1471 Clarence appears to have seized the
whole of the vast estates of the earl, and in March 1472 was created by
right of his wife earl of Warwick and Salisbury. He was consequently
