The Siege and conquest of Jerez de la Frontera took place on 9 October 1264 (other sources cite 3 October 1266) by the Christian troops of Alfonso X of Castile.
The city had been conquered a few years earlier after the Siege of Jerez (1261) from the Andalusian King Ibn Abit, but retaken by the Muslims during the Mudéjar revolt of 1264–1266.[1]
This event is part of the Reconquista, a historical process that took place in Spain between 722 and 1492, during which the Christian Kingdoms of the Iberian Peninsula sought control of the territory that remained under Muslim rule.
