George Plantagenet, Duke of Clarence, an English nobleman who engages in several major conspiracies against his brother, King Edward IV, is executed for high treason in the Tower of London on February 18, 1478, allegedly by drowning in a butt of malmsey wine.
Plantagenet is born in Dublin Castle on October 21, 1449, the sixth child and third surviving son of Richard Plantagenet, 3rd Duke of York, and Cecily Neville, Duchess of York, and the brother of English kings Edward IV and Richard III. His father’s struggle to gain power precipitates the Wars of the Roses (1455–85) between the houses of York and Lancaster.
Soon after Edward IV becomes king in March 1461, Plantagenet is made Duke of Clarence, and in 1462 he is appointed Lord Lieutenant of Ireland. However, around 1468, he falls under the influence of Richard Neville, 16th Earl of Warwick, who is losing the control that he had formerly exercised over the King. In defiance of Edward IV, he marries Neville’s daughter Isabel in Église Notre-Dame de Calais in July 1469. Then, in March 1470, he and Neville secretly support an armed uprising in northern England. When Edward IV discovers their treachery, they flee to France but return in September.
After Edward IV goes into exile, Plantagenet and Neville put the ineffectual Lancastrian monarch Henry VI, deposed in 1461, back on the throne. But Plantagenet soon becomes disenchanted with Neville’s management of the government. When Edward IV returns from exile in March 1471, the brothers become reconciled, and Plantagenet, who fights in the battles that lead to Edward’s restoration, is created, by right of his wife, first Earl of Warwick on March 25, 1472, and first Earl of Salisbury in a new creation.
After his wife dies on December 22, 1476, Plantagenet seeks to wed Mary, Duchess of Burgundy. But when Edward IV objects to that match also, the embittered Plantagenet once more begins scheming against his brother. Edward IV becomes convinced that his brother is aiming at his throne. Plantagenet is thrown into prison, and in January 1478 the King unfolds the charges against his brother to Parliament. He had slandered the King, had received oaths of allegiance to himself and his heirs, and had prepared for a new rebellion. Both houses of Parliament pass the bill of attainder, he is “privately executed” at the Tower of London on February 18, 1478, by tradition in the Bowyer Tower, and soon after the event, a rumour spreads that he had been drowned in a butt of malmsey wine.
Two of Plantagenet’s children survive their father: Margaret Pole, Countess of Salisbury (1473–1541), and Edward Plantagenet, 17th Earl of Warwick (1475–99), who passes the greater part of his life in prison and is beheaded in November 1499.
Plantagenet is a principal character in two of William Shakespeare‘s history plays: Henry VI, Part 3 and The Tragedy of Richard the Third. Shakespeare portrays him as weak-willed and changeable.
