Rashid al-Din Sinan
Medieval Nizari Ismaili missionary in Syria. He reorganized the Nizari community in Syria and played a prominent role in the regional politics of his time, entering into shifting alliances with Salah al-Din (Saladin), the Crusaders, and others to safeguard the independence of his community. Sinan was the original “Old Man of the Mountain” of the Crusaders, who made the Nizari Ismailis famous in medieval Europe as the Assassins together with a number of tales regarding their secret practices. An outstanding organizer and statesman, Sinan led the Syrian Nizaris for some three decades, to the peak of their power, until his death.
