History
In 1682, La Salle recorded the presence of a village of Quinipissa peoples in the vicinity of modern-day Hahnville. In the 1700s, German immigrants to the French colony of Louisiana began settling along the Mississippi upriver from New Orleans in what became known as the German Coast. In the early 1800s, following the sale of Louisiana, the United States established the St. Charles Courthouse in the area and a small community grew up around it. In February 1872, Thomas Sharpe began laying out a village near the courthouse, which he called Flaggville after district judge Othelle J. Flagg. Around the same time, former governor Michael Hahn, who had a sugar plantation upriver from Flaggville, began dividing his land to found Hahnville. Gradually "Hahnville" became the commonly accepted name for the larger area.
