English colonial slavery was racial and hereditary while earlier Indigenous slavery was transitory

Evidence

While there were opportunities for some Native people, who were considered potentially redeemable and assimilable, to be converted to Christianity in regions like New England and the Great Lakes, the rules were different for African captives in the South. Even if they embraced Christianity, they would retain their unfree status, due to new English laws crafted to disallow an escape hatch from slavery by way of Christian conversion. Unlike older forms of Indigenous American slavery in the Southeast that involved the capture of people from different tribes whose status was often transitory, English captivity had become both racial and heritable. — Nikole Hannah-Jones et al., The 1619 Project, 475

Categorization

• DEFINE: Distinguishes ‘racial and heritable’ English slavery from ‘transitory’ Indigenous slavery — a precise definitional contrast central to the reframing argument.
• XREF: The Christian-conversion escape hatch closed by law parallels the class/status signaling in the Immodesty article’s sumptuary laws — identity markers locked by statute.
