During the first Iron Age (7th to 5th c. BC), small tribes who can be considered as proto-Celts, settled in the area. The presence of a civilization called the Boïens installed in the Buch countryside and who moved down to Born country have also been recorded. However, these small tribes were not deeply implanted in the Lande. When the Romans invaded the Aquitaine, they discovered tribes quite distinct from these Celtic tribes, more like the Iberians, organized in ethnic groups known under the name of the Novempopulania.
