The Muslim conquest, between 711 and 716, don’t mean the final of the Christianism. In this mountainous, steep and craggy landscapes had resistors through to the 9th century, then the zone was depopulated, hence the scant remains related to the Muslim and lack of continuity of Cabeza la Vaca with other previous settlement. After the Christian reconquest in the first half of the twelfth century by the Kingdom of Lion and the order of Santiago, around 1230, some huts and cabins, perhaps related to unknown and razed town from the visigothic epoch and survivors of the Muslim domain, were gradually attracting settlers from the North, until the end of century the location was renamed as Cabeza de la Vaca de León, so it started out the modern history of the town. The language of lion spread through Extremadura, however the castilian imposed in the 14th century. The proximity of another Spanish kingdom, Portugal, along with civil wars within Castilla y Leon and terrible plagues led to instability through to the 15th century, when Cabeza de la Vaca consolidated firmly.
