The primary focus of the Reconstruction era in the United States following the Civil War was to rebuild the South and integrate formerly enslaved people into society as equal citizens. This period, lasting from 1865 to 1877, aimed to address the political, social, and economic challenges resulting from the war. Legislation was passed, including the 13th, 14th, and 15th Amendments, which collectively abolished slavery and granted citizenship and voting rights to African Americans. However, Reconstruction faced significant challenges, including resistance from white supremacist groups and the emergence of discriminatory laws known as Jim Crow laws, which sought to undermine these advancements.
