 Also known as the Lënape,(the name of their tribe in their own language), the Delaware people were divided into three dialectal divisions, which later became the basis for the three Clans of the Lënape. These divisions were the Monsi (Munsee) or Wolf, the Unami or Turtle, and the Unilactigo or Turkey. The proper names for the clans as they now exist are Tùkwsit (Wolf Clan), Pùkuwànko (Turtle Clan), and Pële (Turkey Clan). The Delaware Nation is the Pùkuwànko (Turtle Clan).

The Delaware Nation was the first Indian nation to enter into a treaty with the newly formed government of the United States, in 1778. The people of the Delaware Nation originally lived on the eastern seaboard when the Europeans first arrived, in the area that is now the mid atlantic states of  Conneticut, New Jersey, Delaware, New York, Pennsylvania, and Maryland.

There are also true Lenape communities in New Jersey, Oklahoma, and Kansas, which are not federally recognized. A large group of Lenape also exist  in Canada, the Munsee-Delaware Nation.
