Final answer:
Federal actions during Reconstruction included the creation of military districts which were established by the 1867 Military Reconstruction Act to reintegrate Southern states and protect the rights of freedmen.
Step-by-step explanation:
During the period of Reconstruction, the federal government implemented several measures to reintegrate the former Confederate states into the Union. Among the federal actions, the creation of military districts in Southern states was a significant step. This was accomplished through the passage of the 1867 Military Reconstruction Act, which divided the Southern states that had yet to ratify the Fourteenth Amendment into five military districts.
This act, along with the subsequent supplementary acts, known as the Reconstruction Acts, imposed martial law and were aimed at protecting the rights of freedmen. Military overseers spearheaded the process for drafting new state constitutions and ensuring the ratification of the Fourteenth Amendment before these states could rejoin the Union.
