The conquest of Toledo by Alfonso VI (r. 1065–1109) in 1085 opened a period of transformation and restructure in the traditional patterns that had organised the former taifa. While some scholars state that, in the early years of the Christian conquest, the traditional features of the Muslim civilisation endured, it is the aim of this article to discuss to what extent it is possible to admit a real continuity in everyday practices, taking as a prism the experience of the Mozarab community of the city. Our hypothesis is that, under the apparent continuities, a process of transformation began, through which new feudal relations managed to infiltrate the previous forms of organisation of land, taxes and religion in order to undermine their basis and make them conform to northern patterns, applying policies of segregation and cooptation.
