Known previously as the Munsee of the Thames, their land base is the 1,054 hectares (2,600 acres) Munsee-Delaware Nation 1 reserve, with the unincorporated community of Muncey, west from the Oneida Nation of the Thames, as their main community.

John Graves Simcoe, the lieutenant governor, encouraged the Munsee to settle there although Chippewa were already established there.

[citation needed] The Munsee-Delaware First Nation had a registered population of 524 in April 2004, of whom 163 lived on the reserve.

Munsee-Delaware Nation's Chief and Council are elected officials who serve a two (2) year term of office.

Chief and Council are directly accountable to the band membership for the success of the Nation and the conduct of its affairs and for carrying out the community's mission and vision.
