Subsequently, Aragonese troops took multiple Murcian towns and defeated a reinforcement column sent by the Emirate of Granada.

In the first half of the thirteenth century, Castile and Aragon conquered multiple Muslim states in southern Spain.

[5] After this conquest, the Taifa of Murcia became a semi-independent vassal of Castile, ruled by the Baha al-Dawla of Banu Hud.

In late July or August 1264, the Muslim population ("Mudéjars") of Lower Andalusia started a rebellion against Castile, beginning in Jerez and spreading to other towns.

[8] The rebellion was partly caused by Castile's oppressive forcible relocation policy against the Muslims, as well as by instigation from Muhammad I of Granada.

[7] Muhammad I sent troops to help Murcia led by his Banu Ashqilula ally, Abdallah ibn Ali.

[11] Initially the task to suppress the revolt passed to Alfonso's brother Manuel and Grand Master Paio Peres Correia of the Order of Santiago.

[12] Concerned that Castile was fighting on three fronts, Alfonso X asked his wife, Queen Violant to request help from her father, James I of Aragon.

[13] Pope Clement IV allowed James to collect tithe from his dominions for up to three years to fund the crusade.

In turn, the Muslims of Villena, Elda, Petrer, Orihuela surrendered to him, with terms that they were allowed to keep their lands and worship freely.

James offered to ask Alfonso to restore the Murcians' legal rights from before the rebellion: self-government under Castilian suzerainty, freedom of worship, and preservation of lands and properties.

[16] On 23 June, the city formally renewed its allegiance to Castile's king Alfonso X, and requested his pardon for the rebellion.

[19] Alfonso stayed in Murcia between February 1271 and fall 1272, supervising the colonization of the region and establishing a new administration by Christians.
