The uneasy embrace of slavery in colonial America produced an economic boom, rendered the founder’s debates over freedom from kings and despots questionable distortions of truth and logic, slavery enshrined rascism in the U.S. Constitution and made the Civil War inevitable. The War itself created an identity for the United States from which there was no escape, even though it seems from time to time that the Civil War blinks out in relevance. Writer Ta-Nehisi Coates says this narrative has to change. In a piece in this month’s Atlantic, Coates says more black Americans need to study the war and their role in it in order to understand their place in history. Coates is senior editor for The Atlantic, and author of “The Beautiful Struggle: A Father, Two Sons, and an Unlikely Road to Manhood.”
