What did president Grant help pass to prevent southerners from using fear to shut African Americans of the political process?

President Grant helped pass the Enforcement Acts in 1870 and 1871 also known as the Ku Klux Klan Acts. These acts granted the federal government significant power to intervene in the South to protect African Americans from the violence and intimidation by the Ku Klux Klan and other white supremacist groups. The acts allowed the president to suspend the writ of habeas corpus and use federal troops to combat the Klan and other such groups. They also allowed for the prosecution of those responsible for the violence and the punishment of those who denied African Americans their civil rights. In addition the acts allowed the federal government to register African American voters and authorized the use of federal marshals to protect African American voting rights.

The Enforcement Acts were a major step towards protecting African Americans from the terror and intimidation of white supremacists in the South. They were seen as a major victory for African Americans and helped to restore their rights and freedoms.
