Anti-Muslim polemic migrated from Spanish Mozarabs to northern Europe as a weapon

Evidence

The Mozarabs, like their Eastern Christian counterparts, deployed the image of Muslim heresy as a defensive weapon. By portraying Islam as a deviant and debauched version of Christian Truth, they sought to defend their place in the dâr al-Islâm. Reconquista and jihad changed the confessional map of Spain, and Mozarab polemics grew more daring and more outspoken. Petrus Alfonsi brought this Mozarabic tradition north across the Pyrenees. Peter of Cluny adapted the Mozarabic defensive strategy to the spiritual needs of twelfth-century northern Europe: showing little interest in refuting Muslim doctrine or in defending Christian doctrine, he reasserted the primacy of Christian scripture over the Koran and affirmed that Muhammad was a false prophet. — John V. Tolan, Saracens, 877

Categorization

• XREF: Directly grounds the genealogical lineage the reader maps via Anidjar/Aziz/Razack: gives a concrete transmission chain for the heresy-trope — Mozarabs to Petrus Alfonsi to Peter of Cluny.
• SEED: The movement of a polemical template north across the Pyrenees as libraries/power shifted is a clean case study of how Islamophobic discourse migrates geographically with its clerical carriers.
