During Grant's second term, the North retreated from Reconstruction, while southern conservative whites called "Redeemers" formed armed groups, the Red Shirts and the White League, who openly used violence, intimidation, voter fraud, and racist appeals to overturn Republican rule. Northern apathy toward blacks, the depressed economy and Grant's scandals made it politically difficult for the Grant administration to maintain support for Reconstruction. Power shifted when the House was taken over by the Democrats in the election of 1874. Grant ended the Brooks–Baxter War, bringing Reconstruction in Arkansas to a peaceful conclusion. He sent troops to New Orleans in the wake of the Colfax massacre and disputes over the election of Governor William Pitt Kellogg. Grant recalled Sheridan and most of the federal troops from Louisiana.
