El Cid
In the Battle of Cabra (1079), El Cid rallied his troops and turned the battle into a rout of Emir Abdullah of Granada and his ally García Ordóñez. This unauthorized expedition into Granada, however, greatly angered Alfonso and May 8, 1080 was the last time El Cid confirmed a document in King Alfonso's court. This is the generally accepted reason for the exile of El Cid, although several others are plausible and indeed may have been contributing factors to the exile: jealous nobles turning Alfonso against El Cid through court intrigue, Alfonso's own personal animosity towards El Cid, as well as a possible misappropriation of some of the tribute from Seville by El Cid.
