History

The first European settlers in this area were French colonists, whose culture still influences the small city and who imported enslaved people from Africa. A Louisiana Creole population developed, featuring people of color as well as white colonists of largely French descent.

The county was organized by European Americans, who named it after John Hancock, who was a Founding Father of the United States. While more Protestant Americans migrated into this area after Indian Removal in the 1830s, there are still many Catholic families, some dating to both African and French ancestors of the colonial era. Roman Catholic schools still draw area students.

The 1966 movie This Property is Condemned starring Natalie Wood and Robert Redford was filmed in Bay St. Louis, which was called “Dodson” in the movie, with some additional shooting in Biloxi, Mississippi, and New Orleans, Louisiana.
