Campbell Sr. also served as the Vice President of the Georgia Republican Party. As an elected official, “Campbell [Sr.] organized a black power structure in McIntosh County that protected freed people from white abuses, whether against their bodies or in labor negotiations,” and he was rumored to be protected by a 300-person militia. In fact, that power structure lasted for decades, as evidenced by the fact that the county had three black representatives from 1875 to 1907: Amos R. Rodgers (1878-9), Lectured Crawford (1886-7, 1890-1, 1900-1), and William H. Rogers (1902-7).
