Rashid al-Din Sinan

Rashid al-Din Sinan became the leader of the Nizari Ismaili community in Syria, based at the fortress of Masyaf. He consolidated control over a network of fortresses and expanded the sect's influence during the Crusader period.

Rashid al-Din Sinan ordered the assassination of Raymond III of Tripoli, a Crusader count. This act demonstrated the Nizaris' ability to target high-ranking Crusader leaders and influenced the political dynamics of the Crusader states.

Rashid al-Din Sinan met with Saladin, the Ayyubid sultan, after Saladin's failed siege of Masyaf. The meeting resulted in a truce, with Saladin ceasing his campaigns against the Nizaris and allowing them to maintain their fortresses in exchange for non-aggression.

Rashid al-Din Sinan's agents assassinated Conrad of Montferrat, the King of Jerusalem, in Tyre. This act removed a key Crusader leader and was likely carried out in coordination with Saladin, influencing the outcome of the Third Crusade.

Rashid al-Din Sinan died at Masyaf, having led the Syrian Nizaris for over 30 years. He was succeeded by a new leader. His legacy includes the effective use of assassination as a political tool and the survival of the Nizari state in Syria.
