Associators were members of 17th- and 18th-century volunteer military associations in the British American thirteen colonies and British Colony of Canada. These were more commonly known as Maryland Protestant, Pennsylvania, and American Patriot and British Loyalist colonial militias. But unlike militias, the associator military volunteers were exempt from regular mandatory military service. Other names used to describe associators were "Associations", "Associated", "Refugees", "Volunteers", and "Partisans".
