Eldiguzids
The strengthening of the dynasty is connected with the period of Mohammad Jahan Pahlava.  After the death of Sultan Arslanshah in 1175, Jahan Pahlavan, who brought his 7-year-old son Togrul III to power, declared himself his ancestor and, like Shamsaddin Eldaniz, took de facto power. Atabey Jahan Pahlavan suppressed revolts against the central government and established friendly relations with the ruling dynasties in the neighborhood.  Since the period of Jahan Pahlava was a period of stability, cultural spheres developed in the lands under the rule of the Eldenizs.  During the reign of the mentioned Atabey, the capital of the Eldenizs was moved from Nakhchivan to Hamadan.
