Tenth Earl of Warwick
English nobleman. He was active in Edward I's campaigns in Scotland. A leading opponent of Piers Gaveston, he became (1310) one of the lords ordainers and procured Gaveston's banishment. He was largely responsible for Gaveston's death in 1312, although he did not participate in the actual execution.
Guy de Beauchamp, named after the mythical ancestor of the family, Guy the Saxon,whose father, William, was the 1st Earl.
Guy married Alice, widow of Thomas de Laybourne, by whom he had a son, Thomas, the 3rd Earl.
He fought at the Battle of Falkirk, 1298, and was present at the siege of Caerlaverock, 1300.
Guy was present at the death of Edward I, and opposed Edward II and Gaveston, later being involved in the latter's capture and execution. He was also one of the Ordainers, who curbed the power of the king.
He died in 1315, possibly poisoned by friends of Gaveston.
Guy de Beauchamp, his successor, 2nd Earl, so called in memory of his celebrated predecessor, the Saxon, Guy, Earl of Warwick. He acquired high military renown in the martial reign of Edward I, distinguishing himself at the battle of Falkirk, for which he was rewarded with extensive grants of lands in Scotland, at the siege of Caerlaverock, and upon different occasions beyond the sea. In the reign of Edward II he likewise played a very important part. In 1310 he was in the commission appointed by parliament to draw up regulations for "the well governing of the kingdom and of the king's household," in consequence of the corrupt influence exercised at that period by Piers Gaveston, in the affairs of the realm, through the unbounded partiality of the king; and in two years afterwards, when that unhappy favorite fell into the hands of his enemies upon the surrender of Scarborough Castle, his lordship violently seized upon his person, and after a summary trial, caused him to be beheaded at Blacklow Hill, near Warwick. The earl's hostility to Gaveston is said to have been much increased by learning that the favorite had nicknamed him "the Black Dog of Ardenne." For this unwarrantable proceeding his lordship, and all others concerned therein, received within two years the royal pardon, but he is supposed to have eventually perished by poison, administered in revenge by the partisans of Gaveston. The earl married Alice, relict of Thomas de Leybourne, daughter (by Alice de Bohun) of Ralph de Toeni, of Flamstead, co. Herts, and sister and heiress of Robert de Toeni.
