Freed slaves in Mississippi voted overwhelmingly for Republicans in 1874, giving that party a 30,000 vote majority in what had previously been a Democrat stronghold. Democrats reacted with violence to suppress the black vote and black elected leaders. In 1875 the riots in Vicksburg resulted in the murder of some 300 blacks in the city and vicinity, and President Grant sent Federal troops to quell the violence. The statewide elections of 1875 resulted in exactly 25 Republican votes from predominantly black counties; the 30,000 vote majority had disappeared in the face of threats and violence.
The Federal Senate in 1876 commissioned a study of the election, and this is the report. It is full of first-hand accounts of what had occurred in Mississippi, including testimony of murders and assassinations.
