Penobscot in the context of Penobscot River

The Wabanaki Confederacy (Wabenaki, Wobanaki, translated to 'People of the Dawn' or 'Easterner'; also: Wabanakia, 'Dawnland') is a North American First Nations and Native American confederation of five principal Eastern Algonquian nations: the Abenaki, Mi'kmaq, Wolastoqiyik, Passamaquoddy (Peskotomahkati) and Penobscot.

There were more tribes, along with many bands, that were once part of the Confederation. Native tribes such as the Nanrantsouak, Alemousiski, Pennacook, Sokoki, and Canibas, through massacres, tribal consolidation, and ethnic label shifting were absorbed into the five larger national identities.

Dummer's War (1722–1725) (also known as Father Rale's War, the Three Years War, the Wabanaki-New England War, or the Fourth Anglo-Abenaki War) was a series of battles between the New England Colonies and the Wabanaki Confederacy (specifically the Mi'kmaq, Maliseet, Penobscot, and Abenaki), who were allied with New France. The eastern theater of the war was located primarily along the border between New England and Acadia in Maine, as well as in Nova Scotia; the western theater was located in northern Massachusetts and Vermont in the frontier areas between Canada (New France) and New England.

The root cause of the conflict on the Maine frontier concerned the border between Acadia and New England, which New France defined as the Kennebec River in southern Maine. Mainland Nova Scotia came under British control after the Siege of Port Royal in 1710 and the Treaty of Utrecht in 1713 (not including Cape Breton Island), but present-day New Brunswick and Maine remained contested between New England and New France. New France established Catholic missions among the four largest Native villages in the region: one on the Kennebec River (Norridgewock), one farther north on the Penobscot River (Penobscot Indian Island Reservation), one on the Saint John River (Meductic Indian Village / Fort Meductic), and one at Shubenacadie, Nova Scotia (Saint Anne's Mission). Similarly, New France established three forts along the border of New Brunswick during Father Le Loutre's War to protect it from a British attack from Nova Scotia.
