The moment in context
The single most consequential change on the map in this period was also one of the quietest, when Fatimid Egypt passed into Saladin’s hands in 1171 and its long separation from Sunni Syria came to an end. Saladin had been sent to Egypt as Nur al-Din’s subordinate, but by ending the Shia Fatimid caliphate and restoring Sunni allegiance he made himself the country’s ruler, and when Nur al-Din died in 1174 he spent years taking Syria from other Muslims. He engineered his legitimacy as carefully as any conquest, marrying into the Zengid family, winning the Baghdad caliph’s recognition and presenting the whole project as preparation for recovering Jerusalem. By 1186 one power controlled both Egypt and Syria, and the crusader coast lay inside its grip.
