Answer:
The most important change made by Reconstruction state governments was the establishment of civil rights legislation that made it illegal for institutions to discriminate on the basis of race. Additionally, Reconstruction state governments initiated public education systems in the South, which provided education and opportunities for African Americans who had previously been denied access to education under slavery and Jim Crow laws. The Reconstruction Acts of 1867 also divided the South into five military districts and outlined how new governments, based on manhood suffrage without regard to race, were to be established.
