Salah al-Din Yusuf ibn Ayyub (صَلَاحُ الدِّينِ يُوسُفُ بنُ أَيُّوب; 1137-1193 CE; the founder of the Ayyubid dynasty; the Kurdish Muslim military commander who unified Egypt, Syria, and much of the Levant under one banner and recaptured Jerusalem from the Crusaders in 1187 CE) is one of the most studied military and political leaders in world history. His name *Salah al-Din* (righteousness of the faith) captured a genuine quality that even his Crusader enemies acknowledged: Richard the Lionheart sent his personal physician to treat Salah al-Din when he fell ill, and accounts from Crusader chronicles are rare instances of a medieval enemy being treated with genuine respect and even admiration. The Crusader Kingdom of Jerusalem, established in 1099 CE after the First Crusade's brutal sack of the city — in which 40,000-70,000 Muslims, Jews, and Eastern Christians were killed — had held the city for 88 years when Salah al-Din recaptured it. His treatment of the city's inhabitants — permitting ransom and safe conduct, enforcing his soldiers' discipline — stood in deliberate contrast to the Crusaders' 1099 massacre.

Early Life and Rise to Power

Salah al-Din was born in 1137 in Tikrit (present-day Iraq) to a Kurdish family in the service of Zengi (the Atabeg of Mosul). He was trained in the classical Islamic sciences before entering military service under his uncle Shirkuh, one of Nur al-Din’s (Zengi’s son) generals.

In 1169, Shirkuh conquered Egypt — then under the weakened Fatimid Caliphate — on behalf of Nur al-Din. When Shirkuh died two months later, the 31-year-old Salah al-Din took command as vizier to the last Fatimid caliph, al-‘Adid.

The Fatimid transition: When al-‘Adid died in 1171, Salah al-Din ended the Fatimid Caliphate — switching the khutba from the name of the Fatimid caliph to the Abbasid caliph in Baghdad. This transition is significant in the Ismaili narrative: the public Ismaili da’wa in Egypt ended, and the Imam al-Tayyib’s continuation of the Imamate moved to the underground Tayyibi tradition in Yemen.

After Nur al-Din’s death in 1174, Salah al-Din consolidated control over Syria and united the Muslim Near East.


The Battle of Hattin — 1187 CE

The turning point came at the Battle of Hattin (July 4, 1187) — one of history’s most decisive engagements. Salah al-Din lured the Crusader army into the arid landscape near Lake Tiberias (the Sea of Galilee), cutting off their access to water. Surrounded by fire and dehydration, the 20,000-strong Crusader army was destroyed. The Crusader king Guy of Lusignan was captured; Reynald of Chatillon — who had repeatedly violated truces — was personally executed by Salah al-Din.

The True Cross, the Crusaders’ most sacred relic, was captured.


The Recapture of Jerusalem — October 2, 1187

Jerusalem surrendered on 2 October 1187. Salah al-Din’s terms:

The contrast with 1099 was immediate and deliberate: the Islamic world had not forgotten how the Crusaders entered the city, and Salah al-Din’s measured response was understood as an expression of Islamic values of justice (not vengeance).
