In the United States, black genocide is the notion that the mistreatment of African Americans by both the United States government and white Americans, both in the past and the present, amounts to genocide. The decades of lynchings and long-term racial discrimination were first formally described as genocide by a now-defunct organization, the Civil Rights Congress, in a petition which it submitted to the United Nations in 1951. In the 1960s, Malcolm X accused the US government of engaging in a genocide against black people, citing long-term injustice, cruelty, and violence against blacks by whites.
