Piers Gaveston, 1st Earl of Cornwall
Piers Gaveston, 1st Earl of Cornwall (c. 1284 – 19 June 1312) was an English nobleman of Gascon origin, and the favourite of King Edward II of England.
At a young age he made a good impression on King Edward I "Longshanks", and was assigned to the household of the King's son, Edward of Caernarfon. The prince's partiality for Gaveston was so extravagant that Edward I sent the favourite into exile, but he was recalled a few months later, after the King's death led to the prince's accession as Edward II. Edward bestowed the Earldom of Cornwall on Gaveston, and arranged for him to marry his niece Margaret de Clare, sister of the powerful Earl of Gloucester.
