Overview

Duché de Gascogne; Latin Ducatus Vasconiae; from the Vascones (Basques). Capital: Bordeaux. Languages: Gascon, Basque, Latin. Originated as a Frankish march (from 602) to control the Basques south of the Garonne; culturally and linguistically distinct. In 1058 it was united with the Duchy of Aquitaine under William VIII, and its history thereafter merged with Aquitaine/Guyenne — to the Angevin/English crown with Eleanor, and finally to France in 1453. (Early Vasconia may overlap Part 3; here the emphasis is the Basque duchy and its 1058 union.)
