During the presidential election of 1868, the Klu Klux Klan under the leadership of Forrest, and other terrorist groups, had used brutal violence and intimidation against blacks and Republican voters. The Republicans had nominated Union war hero Ulysses S. Grant for the Presidency at their convention held in October. Klansmen took their orders from their former Confederate officers. In Kansas, there were over 2,000 murders committed to suppress blacks and Republicans from voting. In Georgia, Republicans and blacks received threats and beatings at a higher rate. In Louisiana, 1000 blacks were killed to suppress Republican voting. The violent tactics used by the Klan backfired as Grant, whose slogan was "Let us have peace," won the election and Republicans gained a majority in Congress. Grant, however, did lose Kansas, Georgia, and Louisiana where the violence and intimidation against blacks was most prominent. Many in the north, including President Grant, backed the passage of the Fifteenth Amendment that gave voting rights to Americans of African descent and former slaves. Congress and Grant passed the Enforcement Acts from 1870 to 1871, to protect registration, voting, officeholding, or jury Service of African Americans. Under these laws enforced by Grant and the newly formed Department of Justice, there were over 5,000 indictments and 1,000 convictions of Klan members across the South.
