. Abū Sa'īd in particular was confronted by the belligerency of nascent Castile under the rule of Peter of Castile, also known to history as either Don Pedro the Cruel, or Don Pedro the Just. According to historical accounts, Abū Sa'īd wished to surrender to Don Pedro, but the conditions he offered were unclear. What is clear is that Don Pedro welcomed his coming to Seville. It is recorded that he greatly desired Abū Sa'īd's wealth. When Abū Sa'īd met with Don Pedro, the King had Abū Sa'īd's servants killed and may have personally stabbed Sa'īd to death himself. When Sa'īd's corpse was searched, the spinel was found and added to Don Pedro's possessions. In 1366, Don Pedro's illegitimate brother, Henry of Trastámara, led a revolt against Don Pedro. Lacking the power to put down the revolt unaided, Don Pedro made an alliance with the Black Prince, the son of
