Which of the following was part of President Johnson's Reconstruction Plan?

President Johnson's Reconstruction Plan aimed to restore the Southern states to the Union quickly after the Civil War, with a focus on leniency and rapid reintegration. One of the key components of his plan was that rejoining the Union indeed required writing a new state constitution. This stipulation was intended to facilitate the transition and ensure that states could create governments that adhered to the new post-war reality, including the abolition of slavery and other changes prompted by the war's outcome.

The requirement for new state constitutions reflected an understanding that the political landscape had fundamentally shifted, and it was crucial for Southern states to redefine their governance in a manner consistent with the Union's expectations for the post-Reconstruction era. This process allowed states some level of autonomy in shaping their laws and regulations while ensuring that they acknowledged the new constitutional order established by the Thirteenth Amendment, which abolished slavery.

Other options reflect aspects of Reconstruction but do not align with Johnson's approach in the same way. Immediate enfranchisement of all freed slaves was not a part of his plan; rather, it was a more radical Republican goal. Establishing a military government in the South was characteristic of the Radical Reconstruction that followed Johnson's presidency, rather than his initial approach, which sought to minimize federal intervention
