Political reconstruction led to a power struggle between Congress and the President over readmitting southern states to the union and granting citizenship and voting rights to African Americans. The 14th and 15th Amendments aimed to define citizenship and prohibit racial discrimination in voting. Economically, the South was devastated by the war and faced problems rebuilding industry, infrastructure, and agriculture without slave labor. Socially, the Freedman's Bureau and civil rights acts aimed to help former slaves through education, healthcare, and equal protection under the law, though racial tensions remained high.
