The period of barbarian invasion was subject to controversy because several legends took birth there (like at Mimizan that at the battle where St. Galatoire perished under the assault of invaders). However, it was unquestionably after the Roman era the invasion of sand forming modern dunes saw the closure of bays and then the ruin of little ports. Among the people that we meet between the 5th and 10th centuries are the Gascons. In 602 the name Vasconia appeared for the first time, to describe the countryside situated between Garonne and the Pyrenees. The Carolingian influence transformed Vasconia into Gascogne. Next the country was to face the Norman invasions.
