1068 or 1070 to 28 September 1104. King of Aragon and Navarre 1094-1104 . Purported father-in-law of the Cid's daughter.
Son of Sancho Ramirez and Isabel de Urgel. He extended the territory of Aragon through reconquest of adjacent Muslim territories, He won Huesca in 1095 after defeating Emir Mustain of Zaragoza at Alcoraz. He fought the Cid at the battle of Bairen in 1097. Failing to take Zaragoza, he laid siege to Tamarite in 1104. During his reign he reduced the privileges of the infanzones.
His first marriage was to Ines of Aquitaine in 1086. The son from this marriage was Pedro of Aragon, who was either betrothed to married briefly to the Cid's daughter, Maria. However the son would predecease his father in 1104. Maria's marriage to another man, Prince Ramiro of Navarre is historically documented. Pedro was succeeded by his brother, who became Alfonso I of Aragon.
And King Don Pedro of Aragon, and the Count Don Ramon Berenguer of Barcelona, helped Abenalfange, and they were enemies to the Cid because he defended Zulema.
And King Pedro of Aragon came out against him, but my Cid took the Castle of Monzon in his sight; and then he went to Tamarit: and one day as he rode out hunting from thence with twelve of his knights, he fell in with a hundred and fifty of the King of Aragon's people, and he fought with them and put them to flight, and took seven knights prisoners, whom he let go freely.
But King Abenalfange being sorely grieved hereat, sent to King Pedro of Aragon, and besought him to come and help him against the Campeador.
And the King of Aragon gathered together a great host in his anger, and he and the King of Denia came against my Cid, and they halted that night upon the banks of the Ebro; and King Don Pedro sent letters to the Cid, bidding him leave the castle which he was then edifying.
Then was there a brave battle, and many were slain; but my Cid won the day, and King Abenalfange fled, and King Don Pedro was taken prisoner, and many of his Counts and knights with him.
He of Navarre hight Don Ramiro, and he was the son of King Don Sancho, him who was slain at Rueda; and he married with Dona Elvira, the elder: and the Infante of Aragon who married Dona Sol, the younger, hight Don Sancho, and was the son of King Don Pedro.
This King Don Pedro was he whom the Cid Ruydiez conquered and made prisoner, as the history hath related; but calling to mind the great courtesy which the Cid had shown in releasing him from prison, and how he had ordered all his own to be restored unto him, and moreover the great worth and the great goodness of the Cid, and the great feats which he had performed, he held it good that his son should match with his daughter, to the end that the race of so good a man might be preserved in Aragon.
