The purpose was to enforce white supremacy and intimidate blacks through racial terrorism. According to Ida B. Wells of Tuskegee University
The popular image of an angry white mob stringing a black man up to a tree is only half the story. Lynching, an act of terror meant to spread fear among blacks, served the broad social purpose of maintaining white supremacy in the economic, social and political spheres.
Lynching is a form of psychological terrorism. Richard Wright wrote:
his book Black Boy: "The things that influenced my conduct as a Negro did not have to happen to me directly; I needed but to hear of them to feel their full effects in the deepest layers of my consciousness. Indeed, the white brutality that I had not seen was a more effective control of my behavior than that which I knew."
