Gaveston, Piers (pērz găvˈəstən) [key], d. 1312, favorite of Edward II of England. Son of a Gascon knight at the court of Edward I, he was a boyhood playmate of the future Edward II and acquired great influence over him. Edward I exiled him (1307), but he returned on his friend's accession later in the year. He was made earl of Cornwall and married the new king's niece. When Edward was absent in France (1308), Gaveston was regent. His greed and arrogance and the king's reliance on his counsel aroused strong hostility among the barons, who forced (1308) Edward to banish him. He was made lieutenant of Ireland, but he returned to England the following year. In 1311 the lords ordainers, who temporarily controlled the government, exiled Gaveston again. When he returned within the same year, the barons rose in rebellion. He was captured and executed.
