What did the government do to reduce the violence against African Americans after the civil war?

"What did the U.S. government do to 'reduce' violence against Black Americans after the Civil War?"

Answer: NOTHING. The full story has yet to be told. So let's do it.

This was the period after the Civil War, called "Reconstruction." Read W.E.B. DuBois' masterpiece - BLACK RECONSTRUCTION.

ALSO read prof. Eric Foner (Columbia University) - Reconstruction: America's Unfinished Revolution, 1863-1877, Harper and Row.

AND, from 1951, the petition of Black Americans, and allies, to the United Nations: WE CHARGE GENOCIDE.

AND then read Gail Williams O'Brien's The Color of the Law: Race, Violence, and Justice in the Post-World War II South. John Hope Franklin Series in African American History and Culture. Univ of North Carolina Press, 1999.

Then read about the so-called "SUN-DOWN TOWNS" in the U.S. North - including the East, Midwest, and West.
