The French explored the lower Mississippi River in the late 17th century. Initial French-Natchez encounters were mixed. In 1682 René-Robert Cavelier, Sieur de La Salle led an expedition down the Mississippi River. The Natchez received the party well, but when the French returned upriver, they were met by a hostile force of about 1,500 Natchez warriors and hurried away. At the time of the next French visit in the 1690s, the Natchez were welcoming and friendly. When Iberville visited the Natchez in 1700, he was given a three-day-long peace ceremony, which involved the smoking of a ceremonial pipe and a feast.
