Saladin Begins Siege of Jerusalem
Ayyubid sultan Saladin positioned his army before Jerusalem’s walls on September 20, 1187, beginning a two-week siege that ended Crusader control of the city.
Summary
In the wake of Saladin's decisive victory at the Battle of Hattin earlier that summer, which shattered the main Crusader field army and opened much of the Kingdom of Jerusalem to conquest, the Ayyubid sultan turned his attention to the holy city itself. Jerusalem's defenders, led by Balian of Ibelin, faced severe shortages of trained soldiers amid a flood of refugees. On September 20, Saladin's forces arrived outside the walls and established siege positions. The defenders repelled initial assaults while negotiating terms. After roughly two weeks of bombardment and mining operations that breached sections of the fortifications, Balian surrendered the city on October 2 under conditions that allowed many inhabitants safe passage and ransom for others.
Context
By the late twelfth century the Kingdom of Jerusalem had been weakened by internal rivalries and the loss of key leaders. Saladin, who had consolidated power in Egypt and Syria under the Ayyubid dynasty, sought to reclaim Muslim holy sites and reverse the gains of the First Crusade. His victory at the Battle of Hattin on July 4, 1187, destroyed the kingdom’s main field army and left most of its strongholds vulnerable.
What Happened
After capturing Acre, Jaffa, Ascalon and other towns in the weeks following Hattin, Saladin moved against Jerusalem itself. The city’s defenders, commanded by Balian of Ibelin after he was released from an earlier oath, numbered fewer than a hundred trained knights despite an influx of refugees. Saladin’s forces established positions near the Tower of David and Damascus Gate on September 20, employing archers, siege engines and mining operations that created a breach in the northern wall by September 29.
Aftermath
Balian negotiated terms that allowed the majority of inhabitants to depart after paying ransom, with Saladin’s brother al-Adil and others freeing thousands more from the city treasury. The handover on October 2 was orderly; Muslim holy sites were restored and most Christian residents were permitted to leave with their goods under escort.
Legacy
The loss of Jerusalem prompted Pope Gregory VIII to call the Third Crusade, drawing Richard I of England, Philip II of France and Frederick Barbarossa to the Levant. Saladin’s comparatively restrained conduct enhanced his standing among both Muslim and Christian chroniclers, while the city’s administration shifted toward greater tolerance for Orthodox and Eastern Christian pilgrims.
Why It Matters
The fall of Jerusalem to Saladin ended nearly nine decades of Crusader control over the city and triggered the launch of the Third Crusade involving major European monarchs. It shifted the balance of power in the Levant, demonstrated Saladin's military and diplomatic skill, and solidified his reputation across Muslim and Christian worlds while prompting lasting changes in pilgrimage access and holy site administration.
