Medieval Western Europe
A timeline of Western Europe from 800 to 1450 CE — from Charlemagne's coronation through feudalism, the Crusades, the Black Death, and the dawn of the Renaissance.
Coronation of Charlemagne
Pope Leo III crowns Charlemagne Emperor of the Romans on Christmas Day, reviving the concept of a Western empire and binding secular and papal authority.
Viking, Magyar, and Muslim Raids
Waves of invasion devastate Western Europe, destroying centralized authority and accelerating the development of feudalism and castle-building.
Founding of Cluny Abbey
The Benedictine monastery at Cluny is founded, launching a monastic reform movement that will reshape the medieval Church.
Norman Conquest of England

Investiture Controversy
A bitter power struggle between popes and emperors over Church appointments defines the boundary between religious and secular authority.
Pope Urban II Calls the First Crusade
At the Council of Clermont, Urban II calls Christians to recapture Jerusalem — launching nearly two centuries of religious warfare.
Crusaders Capture Jerusalem
The First Crusade succeeds against expectations. Jerusalem falls after a five-week siege, and four Crusader states are established.
Gothic Architecture Emerges
The Abbey of Saint-Denis near Paris pioneers the Gothic style — pointed arches, ribbed vaults, and flying buttresses that will define European architecture.
Saladin Recaptures Jerusalem
Saladin defeats the Crusaders at Hattin and retakes Jerusalem, treating its Christian inhabitants with notable restraint.
Fourth Crusade Sacks Constantinople
Western Crusaders sack the Christian city of Constantinople — one of history's great betrayals, permanently weakening Byzantium.
Magna Carta
English barons force King John to sign the Magna Carta, establishing the principle that even the king is subject to law.
The Black Death
Bubonic plague devastates Europe, killing a third to half of the population and permanently transforming European society, economy, and culture.
