In 1154, the Aquitaine Duchy entered into the Kingdom of England by the marriage of Alinéor (Eleanor) of Aquitaine with Henri II Plantagenêt, and remained so up to 1453. Born was part of the diocese of Bordeaux. The large Albret family played on the rivalry between the King of France and the King-Duke. They came from the heart of the Landais countryside and carried the modest title of "senhor" of Labrit up to 1312, then through purchases, marriages, and inheritances went on to settle in Marensin and Born and then Bazadais. In writings the name of another family who would go on to mark history also appears: Foix-Béarn.
