In 1768, a long-standing colonial dispute was resolved when the boundary line between Nova Scotia and the Massachusetts Bay Colony (which then included the District of Maine) was officially established.
This survey, conducted by royal commissioners, defined the St. Croix River as the border, ending decades of ambiguity and conflict over territory, timber rights, and fishing grounds. The settlement paved the way for increased settlement in eastern Maine and clarified jurisdiction ahead of the American Revolution.
