Those who settled in this area developed into the Lenni Lenape Native Americans. About the year 1000, an agricultural society developed, and small villages dotted what was to become New Jersey. The Lenape began a westward retreat in the face of European settlement and disease beginning in the late seventeenth century, beginning in Monmouth County by the mid-eighteenth century. Although the Lenape presently live in Ontario and Oklahoma, their legacy survives in such names as Mohingson, Luppatatong and Matawan Creeks and Raritan Bay.
The earliest known attempt at European settlement was in 1650 when the south side of Raritan Bay was purchased from the Lenni Lenape by the New Netherland Colony.
