Ramiro II of Aragon

Ramiro II of Aragon 'the Monk' (ca. 1075- August 16, 1154, Huesca), king of Aragon 1134-1137). In 1134, when his brother Alfonso I of Aragon 'the Battler' died heirless, Ramiro was bishop of Barbastro-Roda. He temporarily gave up his monastic vows in order to secure the succession to the crown. Although Ramiro had to put up with the loss of Navarre, which had formed part of his late brother's dominions but in 1134 became independent under García Ramírez, he fought off two other claimants to the throne, one Pedro de Atarés, an illegitimate connection of the royal line, and Alfonso VII of Castile. The reign of Ramiro the Monk, as he is known, only lasted three years - just enough for him to put down his nobles' rebellion, marry Agnes of Poitiers, produce a heiress, Petronila, betrothe her (aged two) to Ramon Berenguer IV of Catalonia, abdicate in her favour and return to monastic life.
