(1764–71), in American colonial history, vigilance society dedicated to fighting exorbitant legal fees and the corruption of appointed officials in the frontier counties of North Carolina. Deep-seated economic and social differences had produced a distinct east-west sectionalism in North Carolina. The colonial government was dominated by the eastern areas, and even county governments were controlled by the royal governor through his power to appoint local officers. Back-country (western) people who suffered from excessive taxes, dishonest officials, and exorbitant fees also became bitter about multiple office holdings. They formed an association called the Regulators, which sought vainly to obtain reforms. They then refused to pay taxes or fees, punished public officials, and interfered with the courts. Finally, the Regulator insurrection was crushed by Governor William Tryon at the Battle of Alamance (May 16, 1771). Many frontiersmen fled to Tennessee, but the legacy of bitterness induced many Regulators to side with the loyalists (loyalist) during the American Revolution, in addition to continuing their own futile agitation for five more years.
