A modern-day vintage poster of the Harlem Hellfighters of WW1 by S. C. James

The Hellfighters, the most celebrated African-American regiment in World War I, confronted racism even as they trained for war, helped bring jazz to France, then battled Germany longer than almost any other American doughboys. (Their nickname’s origin is unclear: it was possibly coined by enemy soldiers, the American press, or both.) Like their predecessors in the Civil War and successors in the wars that followed, these African-American troops fought a war for a country that refused them basic rights – and their bravery stood as a rebuke to racism, a moral claim to first-class citizenship.
