The
Almohades had successfully integrated the
Emirates of the
Iberian Peninsula together with those in
North Africa into a somewhat unstable political entity. The Almohad governors of
Balansiya, Zayd Abu Abd Allah Muhammad and
Zayd Abu Zayd were able to act with complete autonomy, including giving titles of kingship. They never exercised this right by coined money or renouncing their fealty to the Almohad Caliphate or to its emperor. After the Almohad defeat at the
Battle of Las Navas de Tolosa, the empire disintegrated and fractured in smaller kingdoms called
taifas. The most important of these were the
Nasrid Kingdom of Granada or Emirate of Granada, the
Hafsid Taifa of Tunisia, the Banu Zian
Taifa of Algeria, and
Marinid controlled
Morocco. In 1224,
James I of Aragon called on his nobles from
Aragon and
Catalonia to initiate the conquest of
Muslim controlled Balansiya, entering the area through
Teruel.
Zayd Abu Zayd promptly asked the Aragonese monarch for a truce which he accepted in return for one fifth of the income from Balansiya and
Mursiyya. During the summer of 1225, James I attempted to take the castle at
Peñíscola by laying siege to it. That siege was ultimately unsuccessful as the Aragonese nobles abandoned it. By 1228, an indigenous Valencian-Muslim rebellion led by
Ibn Hud, gained enough support to take the city of
Madina Mursiyya and to dominate the regions of
Orihuela,
Dénia,
Gandia,
Xàtiva, and
Al-Yazirat Suquar. The rebellion further laid siege to Balensiya itself, albeit unsuccessfully due to the menace of a relief force from the
Kingdom of Castile. Ibn Hud retired to Madina Mursiyya without taking Balensiya. The pact between the
Christian king and Abū Zayd caused many Muslims to switch their allegiance in favour of
Zayyan ibn Mardanish, the grandson of Abu al-Hajjaj, thinking that Abū Zayd had betrayed them and abandoned
Islam. Abū Zayd fled Valencia and headed north while Zayyan triumphantly entered the city in the winter of 1229 without proclaiming himself king. From Madina Mursiyya, the anti-Almohad rebel, Ibn Hud, laid siege to Valencia, putting pressure on Zayyan, who abandoned the city.
James I of Aragon, who had recently conquered
Majorca in 1229, decided to try once again to conquer the
Taifa of Valencia. == Campaign for Valencia ==
