The King's Secret (Secret du Roi or Secret du Roy in French) refers to the secret diplomatic channels used by King Louis XV of France during his reign.[1] For a period of over twenty years, Louis XV split his diplomacy into official and secret channels, the latter designed to advance Louis XV's personal interests at times at odds with official French policy.
The King's Secret was officially dissolved upon the king's death in 1774; however, in practice, it outlived its creator, and some of its agents were involved in bringing France (and its allies) into the American War of Independence.
