Jerusalem: The Biography

* A dispute over the Fatimid succession gave rise to a murderous breakaway sect of Ismaili Shiites led by Hassan al-Sabbah. He and his Nizaris fled to Persia, where he seized the mountain fortress of Alamut and later they gained fortresses in Lebanon. He made up for his small numbers by launching a spectacular campaign of terrorism against his Sunni enemies. His team of killers, who terrorized the Middle East for over a century, were supposedly under the influence of hashish, and came to be called the Hashishim, or Assassins. The Muslims, though, called them Batini, seekers after secret esoteric knowledge.
