The Nanticoke Lenni-Lenape Tribal Nation (headquartered in Bridgeton, New Jersey) and the Lenape Indian Tribe of Delaware (headquartered in Cheswold, Delaware) are in an intertribal union, "The Confederation of Sovereign Nanticoke-Lenape Tribes." The confederation is an affirmation of the shared history and common ancestry between our interrelated tribal communities, made up of Lenape and Nanticoke families, which have remained in the area of their ancient homeland.

For more than 10,000 years, our tribes called the area of the Delaware River and Bay down through to the Chesapeake Bay, "Home." Our three tribal communities are the modern Lenape and Nanticoke offspring of those 17th, 18th, and 19th Century Lenape Indian communities which history refers to by such names as the Indians of Cohansey Bridge, The Alloways, The Siconese, and The Sewapois... Unami and Unalachtigo families who remained from the Brotherton Reservation in New Jersey, also the Cheswold Indians of Delaware, and those Nanticoke Indians from the Chicone, Broad Creek and Indian River Reservations on the Delmarva Peninsula. Anthropologist and historians from the late 19th and early 20th century called us "Moors" and "Nanticokes." Over the past several centuries, our tribal communities and tribal families have been studied and documented by Brainerd, Fisher, Babcock, Speck, Gilbert, Weslager, Porter, Kraft, The Smithsonian Institute and many others. Our core families include those of documented descent from Lenape and Nanticoke treaty and land grant signers.

Since the early days of Swedish, Dutch and English settlement, almost a half a millennia ago, our Lenape and Nanticoke ancestors intermingled and intermarried in order to survive the swift changes brought by the European incursion into our ancient homeland. While many from our tribes were forced west and north, eventually settling in the mid-western United States and Ontario Canada, the families that remained gathered into interrelated tribal communities and continued our tradition as "keepers of the land."

For many years, our people had segregated American Indian churches, social events, and — in Delaware — separate Indian schools. From the mid 1800's through to the mid 1900's, it was primarily through several tribal congregations that we were able to preserve our culture and defend our people. Eventually, the tribal leadership moved to establish funded services and programming to benefit tribal citizens and to protect tribal sovereignty for future generations.
