Enslaved people resisted their condition in a range of different ways. Oftentimes those ways were small and personal. There were also times when that resistance took on larger, more dramatic forms, like with slave uprisings and rebellions. Today, we'll learn about the Stono Rebellion, which was an uprising led by enslaved people in South Carolina in 1784. We'll also talk about ways that enslaved people resisted in general and methods like enforced illiteracy used by those who sought to keep people in bondage.Clint's book, How the Word is Passed is available now! https://bookshop.org/a/3859/9780316492935Sources and ReferencesIra Berlin, Many Thousands Gone: The First Two Centuries of Slavery in North America (Cambridge: The Belknap Press of Harvard University Press, 1998.Winthrop Jordan, White Over Black: American Attitudes Toward the Negro, 1550-1812 (Chapel Hill: University of North Carolina Press, 1968, reprinted in 2012)Peter Wood, Black Majority: Negroes in Colonial South Carolina from 1670 through the Stono Rebellion (New York: W.W.
