What helped Rutherford B. Hayes become president and the South get home rule?

Rutherford B. Hayes became president largely due to the Compromise of 1877, which resolved the disputed 1876 election. In exchange for conceding the presidency to Hayes, Republicans agreed to withdraw federal troops from the South, effectively ending Reconstruction. This withdrawal allowed Southern Democrats to regain control over state governments, resulting in the return of "home rule" and the implementation of Jim Crow laws that disenfranchised African Americans and solidified white supremacy in the region.
