After an expedition along the Mississippi, French explorer Robert Cavelier de La Salle (1643–1687) captured the river mouth in 1682. The aim was to build a fortified harbor before France’s English and Spanish rivals. In honor of the French crown, the areas crossed were called “La Louisiane.” The fictional representation shows La Salle in a central position reading a proclamation. He is surrounded by a group of people, including French soldiers, some civilians, a priest, and warriors and chiefs of the American Indian tribes. In the background is a river and a dwelling.
