Regulator Movement in mid-eighteenth-century North Carolina was a rebellion initiated by residents of the colony's inland region, or backcountry, who believed that royal government officials were charging them excessive fees, falsifying records, and engaging in other mistreatments. The movement's name refers to the desire of these citizens to regulate their own affairs. An unfair system of taxation prevailed under which less productive land, such as that in the western and Mountain regions, was taxed at the same rate as the more fertile, level soil of the Coastal Plain. These and other hardships contributed to the Regulators' feelings of sectional discrimination and deep distrust of authorities rooted in eastern North Carolina. Led by men such as Rednap Howell, James Hunter, and Herman Husband—considered the movement's chief spokesman—the Regulators organized a resistance to these abuses, first through protest and ultimately through violence.
