Henry and Margaret were decisively defeated at Towton (1461), and Edward was crowned. Warwick was now the most powerful man in England, and the Nevilles received extensive royal favors; but Edward resented the earl's domination. In the midst of negotiations by Warwick to marry Edward to Bona of Savoy, the sister-in-law of Louis XI of France, the king announced (1464) that he had secretly married Elizabeth Woodville. Edward now favored a Burgundian alliance against France, the Woodvilles received favor, and Warwick was gradually pushed into the background.
He formed an alliance with the king's brother George, duke of Clarence, to whom he married his daughter, against Edward's orders. Together they rose against Edward in 1469, defeated the king's forces, and placed Edward in captivity. By the end of the year, however, Edward had regained control, and in 1470, after another abortive rising, Warwick and Clarence fled to France. There Louis XI persuaded them to make up their differences with Margaret of Anjou, and in Sept., 1470, Warwick invaded England as a Lancastrian, defeated Edward (who fled abroad), and restored Henry VI. Within six months Edward secured Burgundian aid, landed in England, and was joined by Clarence. Edward and Warwick met in battle at Barnet; the earl was defeated and was slain in flight.
Although an able diplomat and a man of great energy, Warwick owed much of his greatness to his birth and marriage. By the marriage of his daughter to Clarence and the marriage after his death of another daughter to the duke of Gloucester, later Richard III, all of Warwick's property went to the royal house.
