The Augusta Riot was a collective rebellion of Black citizens in Augusta, Georgia, and the largest urban uprising in the Deep South during the Civil Rights era. Fueled by long-simmering grievances about racial injustice, it was sparked by White officials’ stonewalling in the face of Black citizens’ demand for answers about the beating death of Black teenager Charles Oatman. At its height on the evening of May 11, 1970, 2,000 to 3,000 people participated, ransacking and set fire to White- and Chinese-American-owned businesses, damaging $1 million of property over a 130-block area. White police officers violently suppressed the riot, with the endorsement of Georgia governor Lester Maddox, shoot-to-kill orders from their captain, and reinforcements by the National Guard and State Patrol. Despite the suppression, the riot fundamentally shook the status quo, galvanizing a new wave of activism that opened economic and political doors for Augusta’s Black citizens.
