It was in the reign of Alfonso VI that Rodrigo, or Ruy, Díaz of Vivar (near Burgos), better known as “the Cid,” performed the achievements which have made him a famous character in literature. Until recently he was represented as a fanatically ardent, Christian crusader, ever drawing his sword against the infidel or in defence of any just and noble cause, and performing superhuman prodigies of valor. The true Cid was very far from answering to that description, and was also so typical of his age that his real career has historic value apart from literature. In the civil wars following the death of Ferdinand I, Díaz was a partisan of Sancho II of Castile, and contributed greatly to that monarch’s success,--a victory which was spoiled by the assassination of his patron. Díaz then recognized Alfonso VI, and was sent by the latter to collect the tribute due from the king of Seville. On his return he was accused of having appropriated for himself certain of the funds which he was bringing to the king, and was banished from Castile; possibly Alfonso VI may still have felt resentment over Díaz’s part in the victories of Sancho. Followed by only a few warriors Díaz wandered over Spain, seeking wealth and honors in return for military aid. Finally he took service with the Moslem king of Saragossa, and won fame in all the peninsula as a result of his victories not only against Moslem enemies but more than once against Christian kings; in fine, religion seems not to have entered into his program to any appreciable extent; indeed, the name Cid was applied by his Moslem soldiers, meaning “lord,” or “master.” In 1086 the Moslem king of Valencia, the same one who had been placed on the throne by Alfonso VI, got into difficulties with his subjects, and sought the aid of Saragossa. The Cid was sent with an army of mingled Christians and Moslems to restore the authority of the Valencian monarch. This he did, but under a contract which ignored his Saragossan master and enabled the Cid to become the virtual ruler of Valencia. In 1092 on the death of the king of Valencia the Cid converted his _de facto_ into a _de jure_ rule, reigning until his death in 1099. As monarch of Valencia he was selfish and cruel, like others of his time, sustaining his power by virtue of his army of Christians and Moslems against foes of whatever faith, even against Castile. He espoused one of his daughters to Ramón Berenguer III of Barcelona, and another to a prince of the royal family of Navarre. After his death his state fell before the advance of the Almoravides.
