60-Second Review

Express review

A condensed, point-by-point summary of the module, for reviewing right before a test or exam.

  1. Origins: Jerusalem, Byzantium, and the Path to Crusade. Papal, feudal, and Byzantine pressures converged after the Seljuk victory at Manzikert in 1071 to set the stage for crusade.
  2. The Council of Clermont and the People's Crusade (1095-1096). Urban II's Clermont sermon in November 1095 launched an unexpectedly massive movement, and Peter the Hermit's popular crusade was destroyed before the noble armies even set out.
  3. The First Crusade and the Conquest of Jerusalem (1096-1099). Five noble-led armies converged on Constantinople, took Antioch after a grueling siege, and stormed Jerusalem on 15 July 1099.
  4. The Crusader States and the Military Orders. Four Latin states in the East relied on Italian sea power and on the new military orders — Templars, Hospitallers, Teutonic Knights — for their defense.
  5. The Second Crusade, Bernard of Clairvaux, and the Rise of Saladin. The failed Second Crusade (1147-1149) gave way to Muslim unification under Zengi, Nur al-Din, and finally Saladin.
  6. The Battle of Hattin (1187) and the Third Crusade. Saladin's crushing victory at Hattin in 1187 cost Jerusalem, provoking the Third Crusade led by Richard I, Philip II, and Frederick Barbarossa.
  7. The Fourth Crusade and the Long Thirteenth Century: From Constantinople to the Fall of Acre. The Fourth Crusade's 1204 sack of Constantinople, Frederick II's diplomatic recovery of Jerusalem, and Louis IX's failed expeditions preceded the loss of Acre in 1291.
  8. Crusading Beyond the Holy Land: Iberia, the Baltic, Languedoc, and the Movement's Legacy. Popes extended crusading indulgences to the Iberian Reconquista, the Baltic Northern Crusades, and the Albigensian Crusade, leaving an economic, cultural, and historiographical legacy still debated today.

This module continues after "Vikings and Al-Andalus" in the syllabus. If you haven't reviewed it yet, it may help set the context.
