Why did racial violence increase after 1870?

Racial violence increased after 1870 primarily due to the post-Civil War era's social and political turmoil in the United States. The withdrawal of federal troops from the South and the end of Reconstruction led to the rise of white supremacist groups like the Ku Klux Klan, who sought to restore white dominance through violence and intimidation. Additionally, economic competition and social tensions between races fueled conflicts, particularly as African Americans began asserting their rights and seeking greater social and economic opportunities. This period was marked by a backlash against the advances made by Black Americans during Reconstruction, leading to widespread racial violence and systemic oppression.
