In page Reconquista:

"

The Caliphate of Córdoba was gaining power, and began to attack Leon. King Ordoño allied with Navarre against Abd-al-Rahman, but they were defeated in Valdejunquera in 920. For the next 80 years, the Kingdom of León suffered civil wars, Moorish attack, internal intrigues and assassinations, and the partial independence of Galicia and Castile, thus delaying the reconquest and weakening the Christian forces. It was not until the following century that the Christians started to see their conquests as part of a long-term effort to restore the unity of the Visigothic kingdom.[citation needed]
