 As late as 22 March 1122 Alfonso was still referring to Pedro as "regis altor" (royal protector).It was around this time, in 1121 or 1122, that Pedro made a final peace with his old enemy, Arias Pérez, by marrying to him his own daughter Ildaria.By 1121 Pedro's second son, Fernando, was already a count, because of his influence at the court of Theresa, Countess of Portugal.
