[352] Georgia complied, and on February 24, 1871, its senators were seated in Congress, with all the former Confederate states represented, the Union was completely restored under Grant.[353][ab] Under Grant, for the first time in American history, Black-American males served in the United States Congress, all from the Southern states.[355]
In 1870, to enforce Reconstruction, Congress and Grant created the Justice Department that allowed the Attorney General and the new Solicitor General to prosecute the Klan.[356] Congress and Grant passed a series of three Enforcement Acts, designed to protect blacks and Reconstruction governments.[357][ac] Using the powers of the Enforcement Acts, Grant crushed the Ku Klux Klan.[359] By October, Grant suspended habeas corpus in part of South Carolina and sent federal troops to help marshals, who initiated prosecutions.[360] Grant's Attorney General, Amos T. Akerman, who replaced Hoar, was zealous to destroy the Klan.[361] Akerman and South Carolina's U.S. marshal arrested over 470 Klan members, while hundreds of Klansmen, including the wealthy leaders, fled the state.[362][ad] By 1872 the Klan's power had collapsed, and African Americans voted in record numbers in elections in the South.
