Alfonso VII of León and Castile
The taking of Jaén was perceived as being fundamental to let Kingdom of Castile expand into the Baetic Depression. The difficulty in this conquest were the notable which had been built by the Almohad Caliphate. They had been instrumental in repulsing an attack on the city by Alfonso VII of León and Castile from 1151 to 1152, and another attack by the Almohads in 1162.
