European feudalism othered internal Jews, Gypsies, and regional minorities.

Evidence

Differences between Christians and heathens overlaid earlier lines of distinction that ran between the Roman Empire and its peripheries: the Pax Romana and the world outside. Regional differences in language, food, costume, and customs were significant. In the hierarchy of estates, “others” were primarily those who did not fit in - Jews, Gypsies, travelers, regional minorities such as the Marranos in southern Spain, heathens and nonbelievers. — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 185

Categorization

• XREF: The specific internal-European others list (Jews, Gypsies, Marranos) parallels claims about the Frankfurt-era and Bloodlands treatments of Romani and Jewish persecution as Europe’s internal others.
• ADDENDUM: Reinforces the ‘hierarchy/structure’ theme of the Omi-Winant racial formation material already in the vault by locating non-fit as the estate-era criterion.
• corroborated: 2 independent passages support this claim — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 185
