2. The City That Suffered One of the Medieval Era’s Worst Calamities
The city of Aleppo in northwestern Syria is located right on a precarious geologic fault line that separates the tectonic Arabian Plate from the African Plate. That accident of geology is, to put it mildly, unfortunate for the city and its people. The friction between the two plates makes Aleppo and the region surrounding it particularly susceptible to devastating seismic events. One of the worst occurred during the Crusades on October 11, 1138, when one of history’s deadliest earthquakes shook northern Syria.
Aleppo was a bustling and vibrant city during the medieval era. In the mid-twelfth century, however, the region was ravaged by war as the recently formed Crusader states, such as the nearby Principality of Antioch, vied with the neighboring Muslim states. Aleppo, then part of the Zengid Sultanate, was at the forefront of the anti-Crusader resistance, protected by strong walls and a powerful citadel. Then came the 1138 earthquake, which killed hundreds of thousands in Aleppo, its environs, and the surrounding region.
