New Cassel was one of the first free African American communities on Long Island. It was founded by a group of formerly enslaved African American farmers in the mid 1700s. About the time of the close of the American Revolutionary War, Hessian settlers, mostly from Hesse-Cassel in the Holy Roman Empire and who chose not to return Europe, and settled throughout the area, as well; this gave rise to New Cassel's name, which was chosen in honor of the part of Hesse from which most had come.
