A BuzzFeed-style list pulls back the curtain on under-taught, dark chapters of American history—from J. Marion Sims’s brutal experiments on enslaved Black women and the evolving categories of whiteness, to the Bracero program and mass deportations, Reconstruction-era Black officeholders, convict leasing, Native boarding schools, the Tulsa massacre, Guatemala’s syphilis experiments, Jamestown cannibalism, and Chinese labor on the transcontinental railroad—showing how power, race, and exploitation have shaped the U.S. in ways history textbooks often omit.
