The 18th century saw a rapid succession of owners, including the notorious Scottish banker John Law, who purchased the estate in 1719. Nearly a century later, in 1803, Napoleon ordered his foreign minister Charles Maurice de Talleyrand to acquire the property as a place particularly appropriate for reception of foreign dignitaries, notably Ferdinand VII of Spain, his brother Infante Carlos, Count of Molina and his uncle Infante Antonio Pascual, who would spend six years in Napoleonic captivity at Valençay. The treaty providing for their release in 1813 took the estate's name. Talleyrand took Marie-Antoine Carême as his chef.
