Episode notes
Limpieza De Sangre Reshaped Early Modern Iberia
- Sixteenth-century Iberia institutionalized sangre limpia statutes excluding descendants of converts from professions and religious life.
- These limpieza de sangre laws aligned with Inquisition practices and reshaped social, legal, and genealogical hierarchies.
Prophetic Descent Built Moroccan Power Structures
- Morocco's elite claims relied on prophetic descent (shurafa) rather than formal inquisitorial law, producing a different genealogy-based power.
- The Saadi dynasty rose by asserting sharifian legitimacy to address Iberian occupation and corruption.
Horse Dung That Sparked A Saint's Conversion
- Sidi Ridwan's conversion began when a horse defecated in a Genoa church and locals sold the dung as a relic.
- The Genoese merchant followed the horse, saw the fraud, became disillusioned, converted to Islam, and later rose as a Fessi saint teaching hadith.
