In 1912 in Forsyth County, Georgia two separate attacks on white women resulted in black men being accused and the black population chased out of the county.

One white woman accused a black man of raping her and the other woman was found fatally beaten and raped. Numerous of blacks were arrested and many physically beaten by white mobs. A black preacher was harshly beaten for suggesting that the encounter between the white women and black men might have been consensual.

Five blacks were charged in the second crime, and one was lynched by a mob of thousands at the county jail; two youths (aged 16 and 17) in the case were convicted of rape and murder by an all-white jury and sentenced to death by hanging. Thousands of whites attended the hangings. In the early stages of the unrest, the Sheriff received reinforcements of 25 Georgia National Guard troops, but they could not control the mob.

During 1910, more than one thousand blacks lived in Forsyth County and there were more than 10,000 whites. After the black men had been put on trial and executed for the beatings and rapes of the two white women, bands of white men, known as Night Riders, threatened and intimidated black families in the county. The Night Riders forced the black families out in an early racial expulsion. Most of the blacks lost their land and other property when they fled. Whites took over their abandoned property. Within the next four months, an estimated 98% of the blacks living in the county were gone.
