Viscounty of Béarn

The Viscounty, later Principality of Béarn, was a medieval lordship in the far south of France, part of the Duchy of Gascony from the late ninth century. In 1347, the viscount declared Béarn an independent principality without feudal obligations. It later entered a personal union with the Kingdom of Navarre in 1479 and with France in 1589. In 1620, the prince formally incorporated Béarn as a province of France.
