The Viscountcy Castillon was situated in south-western France. At its centre was the town of
Castillon-sur-Dordogne (now Castillon-la-Bataille). The purpose of the viscountcy, which has existed since the 10th century, was in the defence of the crossing over the river
Dordogne.
The family of viscounts lost their power because of a rebellion of Baron
Guyenne against
Simon de Montfort. At the end of the 13th century, Castillon passed to
Jean I de Grailly, whose descendants ruled in Castillon - apart from a small altercation between England and France - until the 16th century.
The successor to the
House of Grailly from the middle of the 16th century was the
House La Tourd'Auvergne (Turenne). A descendant, André Leberthon, lost his feudal rights over Castillon during the
French Revolution and sold Castillon in 1795.
