Salahuddin and the Reconquest of Jerusalem (1187 CE)

A Fractured Muslim World

When the Crusaders captured Jerusalem in 1099 CE — slaughtering its Muslim and Jewish inhabitants in a massacre that shocked the medieval world — the Muslim political landscape was deeply fragmented. The Abbasid Caliphate was a shadow of itself, controlled by Seljuk sultans. The Fatimid Caliphate in Egypt pursued its own interests. Dozens of local dynasties and city-states competed, allied, and betrayed each other. The idea of unified Muslim resistance to the Crusader states seemed impossible.

Into this world was born Yusuf ibn Ayyub — known to history as Salahuddin al-Ayyubi (Saladin), born in Tikrit in 1137 CE to a Kurdish family. He was raised in the court of Nur ad-Din Zengi, the Syrian ruler who first gave serious direction to the idea of jihad against the Crusaders. Salahuddin initially served under his uncle Shirkuh in the military campaigns to establish Zengid control over Egypt, and when Shirkuh died, Salahuddin emerged as vizier of Egypt — then as its sultan, founder of the Ayyubid dynasty.

Unifying the Muslim World

Before Jerusalem could be reconquered, the Muslim world had to be reunified — politically and spiritually. Salahuddin understood this. Through a combination of diplomacy, military pressure, and genuine religious conviction, he spent years consolidating control over Egypt, Syria, Mesopotamia, and the Hejaz. He ended the Fatimid Caliphate and restored Sunni governance to Egypt. He brought Muslim rulers across the region under a unified command — not by crushing them all, but by persuasion, marriage alliances, and the compelling logic of the jihad project.

Salahuddin was simultaneously a political calculator and a man of sincere faith. He studied hadith with scholars, wore simple clothes, gave away his treasury in charity, and surrounded himself with scholars of religion. His biographer Baha ad-Din ibn Shaddad records that he could rarely hold back tears when the Quran was recited. His jihad was not merely political conquest — it was understood as an act of devotion.

The Battle of Hattin (1187 CE)

The decisive engagement before Jerusalem's reconquest was the Battle of Hattin, fought on July 4, 1187, near the shores of the Sea of Galilee. Salahuddin had baited the Crusader Kingdom of Jerusalem into committing its entire military force — approximately 15,000 men including the best knights of the Crusader states — by launching a feint against Tiberias.

The Crusader leadership, against the counsel of wiser voices, marched through the waterless hills in July heat to relieve Tiberias. Salahuddin's forces harassed them constantly, denying them access to water. By the time the Crusaders reached the twin-peaked hill called the Horns of Hattin, they were desperate with thirst. Salahuddin's army surrounded them, set fire to the dry grass, and attacked simultaneously from all sides. The Crusader army was destroyed. King Guy of Lusignan was captured. The True Cross — the Crusaders' most sacred relic — was taken.

The Reconquest of Jerusalem (October 2, 1187 CE)

After Hattin, the Crusader cities fell in rapid succession. Jerusalem surrendered after a brief siege on the twenty-seventh of Rajab 583 AH — October 2, 1187 CE — the anniversary of the Prophet's Night Journey and Ascension (PBUH). The coincidence was not lost on Muslim historians, who saw in it a divine endorsement of the reconquest.

The contrast with the Crusader conquest of 1099 was deliberate and stark. When the Crusaders had taken Jerusalem, they massacred the population. When Salahuddin took it back, he forbade all killing of civilians. Every resident who paid ransom was allowed to leave freely. Salahuddin personally paid the ransom for many who could not afford it, and his brother al-Adil paid it for a thousand more. The Eastern Christians were allowed to remain and keep their churches. The Jewish community was permitted to return to the city from which the Crusaders had expelled them.

The Man Who Conquered Jerusalem

Salahuddin's treatment of the conquered city set a standard against which all subsequent conquerors have been measured. His biographers record that he wept when he entered Masjid al-Aqsa and saw the minbar (pulpit) that Nur ad-Din had commissioned years earlier for this very occasion — built in anticipation of the reconquest, stored in Aleppo, and brought to Jerusalem the moment the city was retaken.

He died in 1193 CE, having given away so much in charity that he left no money for his funeral expenses. His legacy is inseparable from the values he embodied: the integration of military excellence and sincere faith, of strategic genius and personal humility, of justice even toward enemies. For Muslims, he represents what Islamic civilization can produce when scholarship, governance, and devotion are united in a single purpose.
