Major Religions of Medieval Europe: Christianity Dominant, Minorities Persistent

Medieval Europe's religious landscape was overwhelmingly Christian — but not monolithic. Minority faiths persisted under varying degrees of tolerance and persecution.

Christianity: The Hegemonic Faith

Catholicism (Latin West)

• Universal jurisdiction: Pope (Bishop of Rome) — spiritual + temporal authority
• Sacramental system: 7 sacraments mediating grace
• Latin liturgy, canon law, monastic orders (Benedictine, Cistercian, Franciscan, Dominican)
• Institutional reach: Parishes, bishoprics, universities, hospitals, courts

Eastern Orthodoxy (Byzantine/Slavic East)

• 1054 Schism formalized split — filioque, papal primacy, liturgy
• Autocephalous churches: Constantinople, Alexandria, Antioch, Jerusalem, Russia, Serbia, Bulgaria
• Greek/Church Slavonic liturgy, married clergy (parish), icons, mysticism

Pre-Reformation Dissent

• Waldensians (12th c., Lyon) — apostolic poverty, vernacular scripture
• Cathars/Albigensians (12th–13th c., Languedoc) — dualist, crushed by Crusade
• Lollards (14th c., England) — Wycliffe-inspired, vernacular Bible
• Hussites (15th c., Bohemia) — Hus-inspired, chalice for laity, survived as Utraquists

Judaism: The Enduring Minority

• Demographics: ~0.5–1% of population; concentrated in cities (Rhineland, Paris, Rome, Toledo, Kraków)
• Legal status: Servi camerae regis (serfs of the royal chamber) — protection + exploitation
• Persecution vectors: Crusade massacres (1096, 1147, 1190), blood libel (Norwich 1144), host desecration accusations, expulsions (England 1290, France 1306/1394, Spain 1492, Portugal 1497)
• Intellectual life: Rashi, Tosafists, Maimonides (Sephardic), Halakhic innovation

Islam: The Retreating Presence

• Al-Andalus (711–1492): Córdoba Caliphate → Taifas → Granada — cultural zenith (philosophy, medicine, architecture)
• Sicily (827–1091): Emirate → Norman conquest — Arabic administration persisted
• Balkans (14th–15th c.): Ottoman expansion → Islamization (Bosnia, Albania, Kosovo)
• Mudejars/Moriscos: Muslims under Christian rule → forced conversion (1502 Castile) → expulsion (1609)

Paganism: The Fading Substrate

• Baltic: Lithuanian Romuva — last European pagan state (official conversion 1387)
• Nordic: Iceland official conversion 1000; folk practice persisted
• Slavic: Wendish Crusades (1147) — forced conversion east of Elbe
• Survival: Folk customs, calendar rites, syncretic saints' cults

Interreligious Dynamics

• Convivencia (Iberia): Uneasy coexistence — cultural exchange + legal hierarchy
• Disputationes: Forced theological debates (Paris 1240, Barcelona 1263)
• Conversos/New Christians: Jewish/Muslim converts — Inquisition scrutiny (purity of blood)

Medieval Europe was a Christian theater with persistent minority acts — sometimes tolerated, often persecuted, never equal. The Reformation (1517) would fracture the Christian monopoly itself.
