Three bishops of the name of Frontin succeeded him: Juan (1173–1194); Garcia, who was present at the battle of Las Navas de Tolosa (1212), and Garcia II, the counsellor of James the Conqueror ("el Conquistador"). In a species of national council held at Tarazona, the marriage of James to Leonor of Castile was declared null on account of the relationship existing between them. The Franciscans, Mercedarians, Dominicans, and Trinitarians, and the Cistercian and Poor Clare nuns were established in the diocese at this time.
