Lynchings and White supremacist terrorism against African Americans in pre-Civil Rights Movement America typically involved local law enforcement, making them difficult to fully investigate. The Equal Justice Initiative (EJI) illuminates the statistics and stories behind lynching with Lynching in America: Confronting the Legacy of Racial Terror in America, a new interactive website launched yesterday (June 13).

The racial justice organization says in its announcement that Lynching in America builds on its report of the same name, which investigated more than 4,075 lynchings in 12 southern states between 1877 and 1950. EJI partnered with Google—which previously donated $1 million to support EJI’s forthcoming From Enslavement to Mass Incarceration museum and memorial to lynching victims—to interpret the report’s data via a user-friendly site. The tech company granted $11.5 million to racial justice groups earlier this year, and said in an emailed press release that it would gift an additional $1 million to EJI after the launch of Lynching in America.

Lynching in America features include a color-coded map cataloging lynchings by state and county, including non-Southern states like Illinois and Ohio. The map links to brief videos documenting some of those lynchings.

The website also includes audio testimonies from living descendants of known lynching victims, plus “Uprooted,” a short documentary detailing Luz Myles, Phoebe Dedman and Shirah Dedman’s journey to Shreveport, Louisiana, to learn more about their grandfather Thomas Miles Sr.’s 1912 lynching. EJI additionally adapted the original report with a new lesson plan for high school teachers.
