The Ismaili Assassins were an underground group of political killers who were ready to kill Christians and Muslims alike with complete disregard for their own lives. These devoted murderers were under the powerful control of a grand master who used assassination as part of a grand strategic vision that embraced Egypt, the Levant and Persia and even reached the court of the Mongol Khans in far away Qaraqorum. The Assassins often slayed their victims in public, cultivating their terrifying reputation. They assumed disguises and their weapon of choice was a dagger. The dagger was blessed by the grand master and killing with it was a holy and sanctified act poison or other methods of murder were forbidden to the followers of the sect.

Surviving a mission was considered a deep dishonor and mothers rejoiced when they heard that their Assassin sons had died having completed their deadly acts. Their formidable reputation spread far and wide. In 1253, the Mongol chiefs were so fearful of them that they massacred and enslaved the Assassins women and children in an attempt to liquidate the sect. The English monarch, Edward I, was nearly dispatched by their blades and Richard the Lionheart's reputation was sullied by his association with the Assassins murder of Conrad of Montferrat.
