D.) Southern states rejoined the Union
The reconstruction era also allowed African Americans to gain education in the South, however, i dont think there were a lot of African Americans being able to achieve and keep equal rights. The Freed slaves also still was given prejudice, and it will be a wonder if they even go jobs in the South. The southern economy also grew slowly, as most of their lands were destroyed, and they had to rebuild.
hope this helps
The 13th Amendment abolished slavery.
The 14th Amendment guaranteed African Americans citizenship rights and promised that the federal government would enforce “equal protection of the laws.”
The 15th Amendment stated that no one could be denied the right to vote based on “race, color or previous condition of servitude.”
