Page "Peter I of Aragon and Navarre" Paragraph 2

The Crónica de San Juan de la Peña, a rather late source for Peter's reign, states that Peter was 35 years of age when he died, which places his birth in 1068 or 1069.

As a child Peter was placed in the line of succession to the County of Urgell by the first testament of his uncle Count Ermengol IV, after Ermengol's own son and brothers.

He was not destined to inherit it.

In 1085, two years after his father had conquered Graus ( 28 April 1083 ), Peter was entrusted with Sobrarbe and Ribagorza as a subkingdom with its capital at Graus, which he thenceforth ruled more or less independently with the title of king ( Latin rex ).

On 28 October 1087 Peter joined his father in Pamplona in Navarre, where the two monarchs confirmed the rights of the bishops in the city.

He pursued the Reconquista with vigour in the southeast of the realm.

In 1087 he conquered Estada, in 1088 Montearagón, and on 24 June 1089 Monzón.

These conquests opened up the valley of the Cinca, which he proceeded to conquer as far as Almenar, taken in 1093.
