Ismaili History 646 - Imam in Mongol's camp
Ruknuddin Khurshah is reported to have married a Mongolian woman at the encampment of Halagu in Hamdan. He remained with Halagu for about 3 months and 23 days after the fall of Maimundiz. In the beginning of March, 1257, Halagu sent an embassy to the Abbasid caliph Mustasim, asking for submission. It seems probable that Ruknuddin must have conceived the forthcoming terrible onslaught of the Mongols against the Abbasids, and therefore, he intended to quit the company of Halagu before the operations. Since Lamasar and Girdkuh had not been surrendered, therefore, Ruknuddin was continued to be treated with honour. Ruknuddin sought permission from Halagu to see Mongke in Karakorum. He must have been taken to their operations against the Abbasids, had he not quitted the company of Halagu at Hamdan, and it would have led the enemies of the Ismailis to cultivate another story that the operations against Baghdad had been launched on the directions of the Ismaili Imam. Ruknuddin however succeeded to leave Hamdan for Karakorum.
