The primary aim of Reconstruction in post-Civil War America was to reintegrate the Southern states into the Union and to address the inequalities faced by freed slaves. Following the war's end in 1865, Reconstruction policies sought to rebuild the South's infrastructure and establish new political and social systems that recognized the rights of formerly enslaved individuals. Efforts included the establishment of the Freedmen’s Bureau, civil rights legislation, and amendments to the Constitution, particularly the 13th, 14th, and 15th Amendments. However, Reconstruction faced significant opposition, leading to its eventual collapse and the rise of Jim Crow laws that enforced racial segregation and disenfranchisement.
