The Order of Assassins were the deadliest special forces of the Medieval world. They were masters of disguise and stealth, wielding psychological warfare as their greatest weapon. Originating in 11th-century Persia, the Assassins, led by Hassan-i Sabbah, targeted prominent figures, including Sunni leaders, employing tactics like stabbing with stilettos and slashing with concealed weapons. The Assassins successfully assassinated key figures, instilling fear and dread across the Middle East.
