The Lenni Lenape were a Native American people of the Northeastern Woodlands whose ancestors were part of a migration into the Americas widely believed to date back 15,000 years. As their population grew, they lived in bands and tribes across a vast homeland along the waterways of eastern Pennsylvania, New Jersey, western Long Island, New York Bay, and south along the Delaware River and Bay. Before Europeans arrived, they may have numbered as many as 10,000 to 12,000 and divided into three major groups, the Munsee, the Unalachtigo, and the Unami, each speaking a different dialect of the Algonquian language. They believed in a Great Spirit who created the world and all living things, and in a creation story in which grandfather sky, the waters, a Great Turtle, and a red cedar led to the first Lenni Lenape man and woman; Lenape means original people and the earth is called Turtle Island. Their daily life included fishing, farming, hunting, and gathering wild berries, fruits, and nuts, with family members sharing work as women planted, sewed, cooked, and cared for children, men fished, hunted, and protected the family, and elders knitted nets, made pottery, and prepared animal skins. They were described as hospitable people who welcomed strangers, and tribes from around the east coast and as far as the Ohio Region gathered for ceremonies, marriages, and competitive games. Iron Hill jasper, especially red jasper colored by iron, was quarried by tribes from many miles away for tools such as arrowheads and knives. Wood, feathers, deer parts, hides, bones, antlers, teeth, brains, fats, and other materials were used to make arrows, tools, clothing, ceremonial items, and household necessities, reflecting a belief that nothing from an animal should be wasted. Tobacco was sacred in ceremonies and offerings to the Creator, and when a calumet filled with tobacco was shared in important tribal discussions, the smoke carried prayers upward and those who shared the pipe became brothers. As European settlement spread through Delaware and towns were established, open land and wild animals diminished, and by 1760 most Delaware tribes had moved to western Pennsylvania and Ohio. In the 1860s, most Lenape remaining in the eastern United States were sent to Indian Territory in present-day Oklahoma under the Indian Removal Act of 1830, and most Lenape now reside there, with some communities in Wisconsin, Ontario, and their ancestral homeland in New Jersey.
