Duchy of Gascony

The Duchy of Gascony (also Vasconia; ; ) was a duchy in present southwestern France, roughly corresponding to the modern region of Gascony after 824. The Duchy of Gascony, then known as Wasconia, was originally a Frankish march formed to hold sway over the Basques (Vascones). However, the Duchy went through different periods, from its early years with its distinctively Basque element to the merger in personal union with the Duchy of Aquitaine to the later period as a dependency of the Plantagenet kings of England.
