The fifth but third surviving son of Richard Duke of York, Prince George was the younger brother of King Edward IV. According to the Oxford Dictionary of National Biography, "In 1468 he approved an ordinance that would have made his household the largest and most expensive known for any medieval nobleman. There were to be 399 staff, 188 in the riding household, and the annual cost was £4500. This was considerably grander even than Edward IV's lavish endowment, so much more generous than that of earlier kings towards their brothers". In 1478 Clarence was tried for treason, covicted, and executed by drowning in a butt of malmsey wine.
