With the Kingmaker’s machinations, George’s brother Edward IV was deposed and forced to flee England in 1470. The once-deposed Lancastrian King Henry VI was restored to the throne. However, George began to mistrust his father-in-law, the Kingmaker, and switched his support back to his brother. Edward IV returned to England in 1471, defeated the Lancastrians in a battle in which the Kingmaker was killed, and was restored to the throne. To ensure that the twice-deposed Henry VI would trouble him no more, he had him murdered after he had already executed Henry’s son and sole heir. Edward pardoned his younger brother George and restored him to royal favor.
George could not keep his nose clean, however. In 1478, he once again betrayed his elder brother and was caught in a plot against the king. Finally fed up with his wayward sibling, Edward IV ordered George arrested and jailed in the Tower of London, and had him put on trial for treason. The king personally conducted the prosecution of his brother before Parliament. He secured a conviction and Bill of Attainder against George, who was condemned to death. On February 18th, 1478, karma finally caught up with George Plantagenet, 1st Duke of Clarence. He was executed by being dunked into a butt, or big barrel, of Malmsey wine, and forcibly held under its surface until he was drowned.
