States People Centers Other Rukn al-Dīn al-Hasan ibn Muhammad Khurshāh (or Khwarshāh) (ركن الدين الحسن بن محمد خورشاه) (1230–1256) was the son of 'Alā' ad-Dīn Muḥammad III and the 27th Isma'ili Imam.
Persian historian Ata-Malik Juvayni denigrates the Nizari line of Imamate, claiming that they are not true Alids but instead descended from a daii.
However, at one place he writes (p. 663), "And today, the leader (Ruknuddin Khurshah) of the heretics (the misnomer used for the Ismailis) of Alamut traces his descent from this son (of Nizar)."
[3] However, as winter approached, Hulagu took these gestures to be a means of delaying his seizure of the castles and on 8 November 1256 the Mongol troops quickly encircled the Maymundiz fortress and residence of the Imam.
[5] The recorded attitude of Hulegu toward the surrendered Imam appears ambiguous; at times he treated the Khurshah with great deference and viewed him with "attention and kindness", even presenting him munificent gifts.
En route back to his homeland, Rukn al-Din was put to death in 1256[7] near Toungat (تنغات; reading uncertain, possibly referring to the Tannu-Ola mountains).
