Final answer:
The Radical Reconstruction Act of 1867 aimed to enforce military control over former Confederate states to protect freed people, oversee fair elections, and guide states to write new constitutions and ratify the Fourteenth Amendment.
Step-by-step explanation:
The purpose of the Radical Reconstruction Act of 1867, also known as the First Reconstruction Act, was to enforce military control over former Confederate states that had not yet ratified the Fourteenth Amendment. This act divided these states into military districts and imposed martial law, overseen by Union generals and federal troops. Their roles included protecting freed people and ensuring the registration and voting processes were conducted fairly for freed men. The states were required to write new state constitutions and ratify the Fourteenth Amendment to be readmitted into the Union.
