French explorer Pierre Le Moyne d'Iberville led an exploration party up the Mississippi River in 1698. The explorers saw a red pole marking the boundary between the Houma and Bayagoula tribal hunting grounds. The French name le bâton rouge ("the red stick") is the translation of a native term rendered as Istrouma, possibly a corruption of the Choctaw iti humma ("red pole"); André-Joseph Pénicaut, a carpenter traveling with d'Iberville, published the first full-length account of the expedition in 1723. According to Pénicaut:
European settlement of Baton Rouge began in 1721 when French colonists established a military and trading post. Since then, Baton Rouge has been governed by France, Britain, Spain, Louisiana, the Republic of West Florida, the United States, the Confederate States, and the United States again. In 1755, when French-speaking settlers of Acadia in Canada's Maritime provinces were expelled by British forces, many took up residence in rural Louisiana. Popularly known as Cajuns, the descendants of the Acadians maintained a separate culture. During the first half of the 19th century, Baton Rouge grew steadily as the result of steamboat trade and transportation.
