Alamut Castle
It was assumed that with the initial siege of the Alamut Castle in 1256 the Nizari Ismaili presence in the area would have been completely obliterated. Though the damage was extensive, Nizari forces were able to recapture the Castle in 1275, under the leadership of a son of Imam Rukn al-Din Khurshah, and a descent of the Khwarezmshahs, suggesting that the Mongol invasion did not completely wipe out the Nizari forces in that area. However, under the direction of the son of Hulagu Khan, Mongol forces recapture Alamut in 1282, marking the end of Nizari Ismaili rule in this region.
