context_page_description: The Principality of Sedan was an independent Protestant state centered on the Château de Sedan in the Ardennes. It was ruled by the Prince of 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.
context_section_description: The history of Sedan begins in 1424, when Eberhard II von der Mark (1364–1440) (son of Eberhard I von der Mark and grandson of Engelbert II of the Mark, ruler of the County of Mark) began construction of the Château de Sedan in the vicinity of the Benedictine Abbey of Mouzon.  Erard II von der Mark was the first ruler to style himself Lord of Sedan (Fr.: seigneur de Sedan).  In the following years, the town of Sedan grew up in the area between the Château de Sedan and the Meuse.
  In the wake of the Protestant Reformation, Henri Robert de la Marck and his wife Françoise de Bourbon-Vendôme were attracted to the Huguenot movement.  In 1560, they declared Sedan's independence from the Kingdom of France.  Particularly in the wake of the 1562 Massacre of Vassy, Sedan became one of the leading refuges for French speaking Protestants.  The Academy of Sedan, founded in 1579, became one of the chief Huguenot academies.
  With the death of Guillaume Robert de la Marck in 1588, the principality passed to his daughter, Charlotte de La Marck.  In 1591, she married Henri de La Tour d'Auvergne, who thereupon assumed her titles, becoming Prince of Sedan and Duke of Bouillon.  As such, the principality passed from the House of La Marck to the House of La Tour d'Auvergne.  Charlotte died childless in 1594, and the principality was ultimately inherited by Henri de La Tour d'Auvergne's son by his second marriage.
  Henri de La Tour d'Auvergne was accused of participating in the 1602 plot to assassinate Henry IV of France led by Charles de Gontaut, duc de Biron and the 1604 intrigues involving Henry IV's former mistress, Catherine Henriette de Balzac d'Entragues.  In 1604, Henry IV declared Henri de La Tour d'Auvergne's lands forfeit to the crown of France and led an expedition to Sedan in 1606.  He also participated in a 1613 noble revolt against the king.  Henri de La Tour d'Auvergne's son, Frédéric Maurice de La Tour d'Auvergne, shared his father's antipathy to royal power.  In 1630, he participated in a revolt led by Gaston, Duke of Orléans.
  Sedan finally lost its independence during the Thirty Years' War.  In spite of a victory over French royal forces at the Battle of La Marfée, held 6 July 1641, it soon became obvious that Sedan could no longer resist the forces of Louis XIII of France.  In 1642, Frédéric Maurice de La Tour d'Auvergne participated in the failed conspiracy led by Henri Coiffier de Ruzé, Marquis of Cinq-Mars; in the wake of Cinq-Mars' execution, Frédéric Maurice de La Tour d'Auvergne struck a deal with Louis XIII, who agreed to spare his life and give him a commission in the French army in Italy in exchange for the relinquishment of Sedan's sovereignty.  Sedan was thus annexed to the French crown in 1642.  Frédéric Maurice de La Tour d'Auvergne's younger brother, Henri de la Tour d'Auvergne, Vicomte de Turenne would go on to achieve fame as France's leading general.  In 1709, at the request of Lord Chancellor of France Henri François d'Aguesseau, the Parlement of Paris passed a decree reaffirming the French crown's sovereignty over Sedan.
