Ciudades y poder político en al-Andalus. Una hipótesis sobre el origen de las revueltas urbanas en Murcia en el siglo XIII
Throughout the 13th century a succession of urban revolts took place in al-Andalus, which caused the withdrawal of the Almohad Empire and the establishment of the third taifas, initially led by Muhammad b. Yūsuf b. Hūd al-Mutawakkil. The inability of this emir to hold together this newly-built state, and the continuous insurrections inside and utside of Murcia have led historians to investigate the nature of political power during this period. This article examines each one of these proposals and, on the basis of an analysis of some socio-economic aspects relating to Murcia (being a representative city of al-Andalus and capital of the hūdi movement during the first half of the thirteenth century), proposes a hypothesis on the nature of its power.
¿Fue la crisis política del Occidente musulmán del siglo XIII debida a un cambio climático? Una aproximación histórica al fin del Periodo Cálido Medieval
A succession of revolts during the 13th century led to the end and disappearance of the Almohad Empire and its replacement by regional powers in al-Andalus, the Maghreb and Maghreb al-Aqsa. Historiography has presented the emergence and conflict between these powers as a social, political, cultural and religious phenomenon which explains the Empire’s annihilation or marginalisation. The aim of this study was to contextualise these events from an environmental perspective so that the disintegration of the Almohad Caliphate, the rise of these powers and the consolidation of Hispanic Christian kingdoms can be understood from the perspective of global climate change and a possible agricultural crisis.
La expansión de la ciudad de Granada en época almohade: Ensayo de reconstrucción de su configuración
The city of Granada had increased in various points in particular all along the banks of the river Darro. We should not consider it as a simple growth of the population but much as a like a policy of the current political power, or at least as an orientation by the rulers. 
As much as the written sources as the the archeological surveys enable us to apreciate the stages of this urban growth, wich had started with the Almohade reign and had climaxed during the Nazari period. At that time we asist to the transformation of an agricultural area of the site to a new urban fabric of the city, as it had been maintained a rural life style inside the walled city
