Qui es va casar amb Sancha de Navarre?

Sancha de Navarre ou Sancie (c. 1144-1150 - 1176) est une infante de Navarre, devenue par mariage vicomtesse de Béarn puis dame de Molina.

Pedro Manrique de Lara (died January 1202), commonly called Pedro de Molina or Peter of Lara, was a Castilian nobleman and military leader of the House of Lara. Although he spent most of his career in the service of Alfonso VIII of Castile, he also served briefly Ferdinand II of León (1185–86) and was Viscount of Narbonne by hereditary right after 1192. He was one of the most powerful Castilian magnates of his time, and defended the Kingdom of Toledo and the Extremadura against the Almohads. He also fought the Reconquista in Cuenca, and was a "second founder" of the monasteries of Huerta and Arandilla.

Pedro was married three times. By his first marriage, to a Navarrese princess, he forged a connection with the lineage of the folk hero El Cid, and scholars have suggested that Lara patronage lies behind the epic Poema de mio Cid. Pedro's second wife was a relative of Henry II of England. Pedro's trans-Pyrenean connexions explain his adoption of seals for authenticating documents; he is the first Spanish aristocrat from whom an examples survives. He also adopted the style "by the grace of God" to indicate his independence in ruling the lordship of Molina, which he inherited from his father.
