a French politician of the 17th century. For a time, he was secretary of the King's Chamber, and he also director of the Gazette de France. In 1677, he was named ambassador at the Ottoman Court. Louis XIV communicated to the Turks that he would never fight on the side of the Austrian Emperor Leopold I, and he instead massed troops at the eastern frontier of France. These reassurances encouraged the Turks not to renew the 20-year 1664 Vasvár truce with Austria and to move to the offensive. Guilleragues died of apoplexy in Constantinople.
