In the context of the United States during the second half of the 19th century, analyze the extent to which the post-Civil War Reconstruction policies (1865-1877) transformed social, economic, and political structures in the South. You must evaluate various viewpoints and perspectives regarding the effectiveness of these policies as illustrated in the accompanying documents, which range from government reports, personal correspondence, and articles from contemporary newspapers.

In your analysis, address both the achievements and limitations of Reconstruction efforts, particularly in the areas of civil rights for African Americans, economic recovery, and the long-lasting impacts of these changes on Southern society. Use the documents provided, as well as your knowledge of the historical context, to support your arguments.
