Founded in 1822, the Maine Historical Society is the third oldest state historical society in the United States. he Maine Historical Society preserves the heritage and history of Maine: the stories of Maine people, the traditions of Maine communities, and the record of Maine's place in a changing world. Because an understanding of the past is vital to a healthy and progressive society, we collect, care for, and exhibit historical treasures; facilitate research into family, local, state, and national history; provide education programs that make history meaningful, accessible and enjoyable; and empower others to preserve and interpret the history of their communities and our state.
