Jellal-ed-deen took a more active part in the politics of his neighbours than his predecessors had done. He formed an alliance with the Atabeg Mozaffer-ed-deen (_Causing the Religion to be victorious_), the governor of Azerbeijan, against the governor of Irak, who was their common enemy. He even visited the Atabeg at his residence, where he was received with the utmost magnificence, and each day the Atabeg sent 1,000 dinars for the expenses of his table. The two princes sent to the khalif for aid; their request was granted; and they marched against, defeated, and slew the governor of Irak, and appointed another in his place. After an absence of eighteen months Jellal-ed-deen returned to Alamoot, having in the mean time, by his prudent conduct, greatly augmented the fame of his orthodoxy. He now ventured to aspire to a connexion with one of the ancient princely houses of the country, and asked in marriage the daughter of Ky Kaoos, the prince of Ghilan. The latter having expressed his readiness to give his consent, provided that of the khalif could be obtained, envoys were despatched to Bagdad, who speedily returned with the approbation of Nassir-ladin-Illah, and the princess of Ghilan was sent to Alamoot. The mention of Ghilan and of Ky Kaoos presents an opportunity, which we are not willing to let pass, of diversifying our narrative by an excursion into the regions of Persian geography and romance, which may cast a gleam of the sunshine of poetry over the concluding portion of our history of the dark and secret deeds of the Ismaïlites.
