Answer:
In 1867, following the American Civil War and the abolishment of slavery, the Republican-dominated U.S. Congress passed the First Reconstruction Act over the veto of President Andrew Johnson. The act divided the South into five military districts and outlined how new governments based on universal manhood suffrage were to be established.
With the adoption of the 15th Amendment in 1870, a politically mobilized African-American community joined with white allies in the Southern states to elect the Republican Party to power, which brought about radical changes across the South. By late 1870, all the former Confederate states had been readmitted to the Union, and most were controlled by the Republican Party thanks to the support of black voters.
In the same year, Hiram Rhodes Revels, a Republican from Natchez, Mississippi, became the first African-American to sit in the U.S. Congress, when he was elected to the U.S. Senate. Although black Republicans never obtained political office in proportion to their overwhelming electoral majority, Revels and a dozen other black men served in Congress during Reconstruction, more than 600 served in state legislatures and many more held local offices.
