The Battle of Errozabal (Rencesvals) is the one of the most significant historical events of eighth century Vasconia and in all Western Europe. The present monograph examines Charlemagne’s campaign from the perspective of military history but also as part of a complex socio-political process that began after the Muslim conquest of the Iberian Peninsula in 711 and culminated with the creation of the Kingdom of Pamplona in 824. The battle had major (and largely underappreciated) consequences for the Carolingian Empire. It also enjoyed a remarkable legacy as the topic of one of the oldest European epic poems, La Chanson de Roland. The events that took place in the Pyrenean pass of Errozabal on 15 August 778 defined the development of the Carolingian world, and lie at the heart of the early medieval contribution to the later medieval period.

"The Basque perspective is largely unaddressed in studies of Charlemagne and the infamous battle at Rencesvals/Errozabal during which the great emperor’s rearguard suffered a catastrophic defeat. Xabier Irujo’s book not only addresses that lack but puts forward a series of compelling arguments as to why the Basque involvement has not received more in-depth study. As such, this book provides an interesting example of how reading absence in the archive can yield fruitful and transformative perspectives."

''Xabier Irujo has produced another in a string of fine studies examining the pious fictions and malevolent lies told about or perpetrated upon the Basques.''
