Life under the Rohans is not a long calm river. Indeed the religious wars between Protestants and Catholics are over. The Edict of Nantes which put an end to the conflict was signed in 1598 by Henry IV. It authorizes religious freedom and still allows the great feudal lords to raise armies and hold a stronghold. It does not take less for the Protestants to resume the fighting that will be called “the Huguenot wars” from 1621 to 1628. Clashes are frequent and spread rapidly throughout the southwest. The Duke and Duchess are devout Protestants. The Park and its inhabitants quickly became an active center of the revolt against King Louis XIII.
The son of Catherine and René, Henri de Rohan took the lead of the Protestant armies with the support of his brother Benjamin and his mother to go and fight the king’s armies led by Richelieu. He knows the Vendée well, having been its bishop. Cornered in La Rochelle in 1627 where it was waiting for help from the English, Henri’s Protestant army was besieged and had to surrender in 1628, after eating horses, rats, dogs, cats and… to finish boiled horse saddles ! Richelieu, to avoid a new rebellion, decides to dismantle all the castles of the Protestant leaders. This is how the Château du Parc Soubise was destroyed and then sold. Henri de Rohan is chased out of court by Catherine de Medici. A misfortune never arriving alone, the daughter of Henri de Rohan, Marguerite, falls in love with a noble Catholic and from an equally old but less prestigious family, Charles-Auguste de Chabot. She marries him out of love, to the despair of her parents but with the agreement of Louis XIV, who was only too happy to see the last offspring of this illustrious Protestant family enter the bosom of the Catholic Church!
