See it on the Bible & Christianity map →What it is
Byzantine Emperor Alexios I asked the pope for soldiers against the Seljuk Turks. Urban II's sermon at Clermont in November 1095 turned this into an armed pilgrimage. A disorganized 'People's Crusade' under Peter the Hermit was destroyed in 1096, after crusading mobs massacred Jews in Rhineland cities. The main armies took Nicaea (1097), Antioch (1098) and finally Jerusalem, killing much of its Muslim and Jewish population. Four crusader states followed, including the Kingdom of Jerusalem.
Why it matters
Its unlikely success set the pattern for two centuries of crusading and fixed the idea of holy war in the West. Its massacres scarred Jewish and Muslim memory.
Sources and history
Eyewitness accounts survive, including the Gesta Francorum and Raymond of Aguilers, plus Anna Komnene's Alexiad and Arab chronicles. Hebrew chronicles record the 1096 Rhineland massacres.
Questions and debates
How many died in Jerusalem is uncertain. Ibn al-Athir's figure of 70,000 is considered exaggerated; modern estimates run from about 3,000 to over 10,000. Estimates vary.

▸The Crusades began with First Crusade takes JerusalemHistorical record
The connection
The First Crusade was the first and most successful crusade. Its capture of Jerusalem in 1099 seemed to prove the idea worked, and the crusader states it founded needed defending, prompting the Second Crusade after Edessa fell in 1144.
When and where
Called at Clermont in 1095; armies set out in 1096 and reached Jerusalem in 1099.
Historical evidence
Numbering the crusades is modern, but medieval writers already saw 1095–1099 as the start of a movement.
Questions and debates
Historians debate whether it succeeded through faith and determination or luck: Muslim rulers in Syria were divided, and the Fatimids and Seljuks were rivals.
▸First Crusade takes Jerusalem answered a plea for help from Constantinople, the 'New Rome'Historical record
The connection
Byzantine Emperor Alexios I Komnenos asked Pope Urban II for Western soldiers to fight the Seljuk Turks. The crusade armies gathered at Constantinople in 1096–1097, swore to return former Byzantine lands, then crossed into Asia Minor. Mistrust grew when crusaders kept Antioch for themselves.
When and where
Council of Piacenza, March 1095, received Alexios's envoys; armies at Constantinople 1096–1097; dispute over Antioch, 1098.
Historical evidence
Anna Komnene's Alexiad, crusader chronicles and the record of the Piacenza council all mention Alexios's appeal.
Questions and debates
Alexios wanted mercenaries, not a mass movement; how far Urban reshaped or exaggerated his request is debated.
