The document summarizes key events of Reconstruction, including: 1) Radical Republicans imposed stricter rules on the South compared to President Johnson's more lenient plan, placing the South under military rule and requiring new governments be formed that allowed African American men to vote. 2) Radical Republicans clashed with President Johnson over his firing of Stanton, leading to Johnson becoming the first president to be impeached. 3) The 15th Amendment was passed, prohibiting states from denying men the right to vote based on race, allowing African American men to vote. This led to over 600 being elected to state legislatures.
