And in Alabama, the editorial board of the Montgomery Advertiser published a public apology for its previous coverage of lynching on Thursday—the same day the National Memorial for Peace and Justice opened in downtown Montgomery as a monument to victims of white supremacy in the United States.

In the editorial, the board wrote, “We take responsibility for our proliferation of a false narrative regarding the treatment of African-Americans in those disgraceful days. … We propagated a world view rooted in racism and the sickening myth of racial superiority. … We must never be as wrong as this again.”

The Montgomery Advertiser was among many white-owned newspapers across the United States that failed to investigate—and at times even celebrated—the white mob violence that killed thousands of African Americans throughout U.S. history. Instead, it was black journalists, mostly notably Ida B. Wells, who exposed the horrors of lynching to the world.
