Reconstruction era began after the Civil War in America. The main goal was to improve politics, economic, social, and the inequities of slavery. Reconstruction policies fail because of corruption, violence, and democrats. Freed slaves often encountered racial violence and hatred. Southern Whites prevented them from voting, which threatened their political rights. KKK (Ku Klux Klan) terrorize Blacks through lynching and attempted to steal rights based on colour.
The removal of Union troops from the South led to the collapse of reconstruction, which allowed Democrats to take over the South.
It was in the 1930s and to some extent the 1940s that the US Government started to take a much larger role in the US economy, primarily through Roosevelt's New Deal programs.
