The concept of piracy in nineteenth-century American abolitionist rhetoric

American abolitionists used the concept of piracy as a rhetorical and tactical device to attack the institution of slavery during the antebellum period. Activists branded slaveholders as ‘pirates’ in order to delegitimize the validity of slave owners' title in stolen people and recognize enslaved peoples' rightful self-ownership. The pirate label further conveyed that slaveholders' violence against slaves was illegal and that enslaved people could lawfully use lethal force to resist those who held them captive, assaulted them, or kidnapped them. Thus, abolitionists characterized slave owners as pirates not only to stigmatize slaveholding but also to shape legal perspectives on slavery by reversing presumptions about property rights and about slavery-related violence.
