Beneath the destroyed minaret of Mosul, known as the "hunchback," rests the rubble of what used to be the great mosque of the city. The historical Grand al-Nuri Mosque was built eight centuries ago by Noureddine Zanki, a medieval Muslim leader who paved the way for Saladin, the founder of the Ayyubid dynasty, to confront the crusaders and take over Jerusalem after the decisive battle of Hattin in 1187 — by making Sunni Muslim orthodoxy prevail over Shiism.
Back then, the Muslims’ lands were annihilated by the crusaders, while their leadership was weak and divided between the Abbasid dynasty in Baghdad and the Fatimid rule in Cairo, alongside other small Islamic princedoms scattered from Persia to Mosul to Aleppo. The Shiite-Sunni rift during that period reached its peak, and Zanki played an important role in restoring Sunni power by defeating the Shiite Hamdanid dynasty that ruled from Mosul to Aleppo in today’s Iraq and Syria.
