During the American Revolution, the Munsee- and Unami-speaking Lenni Lenape (also called Delaware) bands of the Ohio Country were deeply divided over which side, if any, to take in the conflict.
The Unami (People Down River) and Unalachtigo (People Who Live Near the Ocean) lived in the central and southern part of the homeland.
Unami Delaware was spoken in the area south of Munsee speakers in the Delaware River Valley and New Jersey, south of the Delaware Water Gap and the Raritan Valley.
