Final answer:
The government implemented the Reconstruction Acts of 1867 to divide the South into five military districts and establish new state governments with suffrage for black men, leading to the ratification of the Fourteenth Amendment and their re-admittance to the Union.
Step-by-step explanation:
The government divided the South into five military districts and called for the creation of new state governments, with black men given the right to vote, by implementing the Reconstruction Acts of 1867. These acts were a series of legislation enacted by Congress that marked a significant transformation in the Reconstruction period following the Civil War. The Military Reconstruction Act imposed martial law and designated Union generals to oversee each district, ensuring the protection of freed people and overseeing the registration and voting process of African American men. New state constitutions were written, and once these states ratified the Fourteenth Amendment and abolished black codes, they could re-join the Union.
