After the French and Indian War ended in 1763, Bayou Manchac (originally known as Rivière d'Iberville or the Iberville River) became an international border between the British (West Florida) and Spanish (Isle of Orleans) colonial territories. This bayou (which now forms the southern border of the City of St. George) runs from the Mississippi River on the west to the Amite River on the east.
Native Americans, specifically the Choctaw, were known to have lived in southeast Louisiana when Europeans first arrived. In 1764, after encroachment by European settlers, the Alabama-Coushatta and Pakana Muscogee Indians migrated into Louisiana, just north of Bayou Manchac.
