The Principality of Sedan (French: Principauté de Sedan) was an independent Protestant state centered on the Château de Sedan (now the city of Sedan) in the Ardennes. It was ruled by the Prince of Sedan (prince de Sedan), who belonged to the noble La Marck and La Tour d'Auvergne families. The Princes of Sedan asserted and acquired recognition of their sovereignty gradually between the 1520s and 1580s by means of adopting the princely title, minting coin, legislating and signing treaties. In 1641, during the Thirty Years' War, the Prince submitted to France and his principality was occupied the following year. In 1651 the reduced principality was exchanged for other lands in France and was annexed to the crown.
