Hundred packed a theater in Watertown on Saturday to celebrate an event that took place 250 years before. The town was the site of the signing of the United States’ first treaty with a foreign nation — the Treaty of Watertown. Descendants of the signers of the document from the Mi’kmaq and Maliseet tribes emphasized that the agreement that was forged as a wartime alliance also created friendships and provided rights and protections for the signers that are still important in 2026. The City of Watertown joined with the Historical Society of Watertown, and members of Maliseet, Mi’kmaq tribes, as well as representatives of the Massachusett Tribe, whose territory includes Watertown, to plan a grand celebration of the 250th anniversary of the Treaty of Watertown on Saturday, July 18, 2026 at the Mosesian Center for the Arts. Around 50 members of the Mi’kmaq and Maliseet tribes came down from Maine, and parts of Canada for the Treaty celebration.
