 On 11 December 1102 Peter was in Estella on the border with Castile, perhaps seeking the aid of Alfonso VI after a particularly disastrous autumn for the Christians of eastern Spain.In 1104 Peter granted a "fuero" to all the "infanzones" of his realm, retaining his right to require three-day field service.Peter's first marriage, to Agnes of Aquitaine (betrothed 1081), was arranged by his father and performed in the capital of Jaca in January 1086.
