Blood Politics Shaped Divergent Elites
- Sixteenth-century Iberia and Morocco both developed hereditary purity discourses but in different institutions: limpieza de sangre statutes in Spain and claims to prophetic descent in Morocco.
- These parallel genealogical logics produced distinct political elites and justify exclusion or rulership based on perceived bloodlines.
Horse Dung Sparks A Conversion Story
- Sidi Ridwan's father converted after seeing a horse defecate in a church and priests selling the dung as a relic.
- The Genoese merchant then moved to Fez, married a Castilian refugee, and his son Sidi Ridwan became a renowned 16th-century Fessi saint and hadith scholar.
Teresa's Hemorrhage Became Her Relic
- Teresa of Avila was the granddaughter of a man accused of Judaizing and died from a prolonged vaginal hemorrhage that continued after death.
- Her postmortem bleeding became treated as miraculous relic material, sold on cloths and venerated despite associations of menstrual blood with impurity.
