Mind-Benders of Jewish History
The Ramban was alive when the Mongols destroyed Baghdad
In 1258 the Mongol army under Hulagu Khan sacked Baghdad and ended the Abbasid Caliphate — one of the great turning points of medieval history. The Ramban was then a sage of about 64 in Catalonia; less than a decade later, he would make his own journey to settle in the Land of Israel.
