Dummer's War (1722–1725), also known as Lovewell's War, Father Rale's War, Greylock's War, the Three Years War, the 4th Indian War or the Wabanaki-New England War of 1722–1725, was a series of battles between British settlers of the three northernmost British colonies of North America of the time and the Wabanaki Confederacy (specifically Mi'kmaq, Maliseet, and Abenaki), who were allied with New France. The war took place variously in Nova Scotia, New Hampshire, and Massachusetts (which included present-day Maine and Vermont). The root cause of the conflict was tension over the ownership of these regions. The New Englanders were led primarily by Lt. Governor of Massachusetts William Dummer, Lt. Governor of Nova Scotia John Doucett and Captain John Lovewell. The Wabanaki Confederacy was led primarily by Father Sébastien Rale, Chief Gray Lock and Chief Paugus.
The treaty that ended the war marked a significant shift in European relations with the Mi'kmaq and Maliseet. For the first time a European power formally acknowledged that its dominion over Nova Scotia would have to be negotiated with the region's indigenous inhabitants.
The final major battle of the war - the Battle of Pequawket, or "Lovewell's Fight" - was fought between Captain Ranger John Lovewell, who led the New England troops, and Chief Paugus, who led the Abenaki. Both leaders were killed in the conflict. The battle marked the end of hostilities between the English and the western Wabanakis of Maine. This conflict was a turning point. So important was it to western Maine, New Hampshire and even Massachusetts colonists that the Fight was celebrated in song and story, and its importance was not eclipsed until the American Revolution. More than one hundred years later Henry Wadsworth Longfellow (poem, "The Battle of Lovells Pond"), Nathaniel Hawthorne (story, "Roger Malvin's Burial") and Henry David Thoreau (passage in the book A Week on the Concord and Merrimack Rivers) all wrote about Lovewell's Fight. Paugus Bay, the town Paugus Mill (now part of Albany, New Hampshire) and Mount Paugus in New Hampshire were named after Chief Paugus.
