The Basque Countries during the High Middle Ages. Armando Besga Marroquín.

The history of the Basque Countries from the invasion of the barbarians in the year 409 to the death of the King of Pamplona, Sancho III the Elder, is very difficult to do due to the lack of sources and the problems that most news about archaeological finds usually present. ; in many cases it is also impossible. This book contains the studies carried out over two decades (from 1993 to 2012) in which the author considered that there was a sufficient basis to make a contribution or solve a problem.
