The feeble hand of a woman was the cause of his downfall. The beautiful and sprightly Leonora de Guzman, who had so enthralled the king with her charms that he was more faithful to her than to his wife, hated the favorite Gonzalo Martinez, and succeeded in making the king believe that he spoke ill of him. Alfonso desiring to learn the real truth of the matter sent a command to Gonzalo to present himself before him in Madrid; he, however, disobeyed the royal command. To be able to defy the anger of the king, he stirred up the knights of the Order of Alcantara and the citizens of the towns assigned to his government, to rebel against his sovereign, entered into traitorous negotiations with the king of Portugal and with the enemy of the Christians, the king of Granada. Alfonso was forced to lead his nobles against him, and besiege him in Valencia de Alcantara. In mad defiance, Gonzalo directed arrows and missiles to be aimed at the king, which mortally wounded a man in the vicinity of Alfonso. But some of the knights of the Order of Alcantara forsook their Grand Master, and surrendered the stronghold to the king. There remained nothing for Gonzalo except to yield. He was condemned to death as a traitor, and was burnt at the stake (1336), and thus ended the man who had sworn to annihilate the Jews. The Castilian congregations thereupon celebrated a new festival of deliverance, in the same month in which the evil plans of Haman against the Jews had recoiled on his own head. Alfonso again received the Jews into his favor, and raised Moses Abudiel to a high position at his court. From this time till the day of his death, Alfonso XI acted justly towards his Jewish subjects.
