Louisiana's history began with Native American tribes, such as the Caddo and Choctaw, who inhabited the region for thousands of years. In 1682, René-Robert Cavelier, Sieur de La Salle claimed the territory for France, leading to the establishment of New Orleans in 1718. The area changed hands multiple times, becoming a Spanish colony in 1763 before returning to France in 1800. In 1803, the United States acquired Louisiana through the Louisiana Purchase, significantly expanding its territory. The state played a crucial role in the Civil War, with New Orleans being a key strategic port. Today, Louisiana is known for its rich cultural heritage, including Cajun and Creole traditions.
