The Analytic Study Effective Factors on the Political and Military Relationship of Iraqi Seljuk and Eldiguzids (541-590 A.H/1146-1194 A.G).

Eldiguzids (541-622 A.H /1146-1225 A.G) was one of the local Atabegs governments in Seljuk period which played an important role in political changes of Iraqi Seljuk in its late decades. This local government was an obedient of Iraqi Seljuk had some narrow relationship with Iraqi Seljuk (541-556 A.H /1146-1160 A.G). This government managed to give sultanate to the prince who was under its supervision in 556 A.H/ 1160 A.G. This period continued until collapse of Iraqi Seljuk in 590 A.H/ 1194 while Eldiguzids governed as Atabegs Sultan and their relationship with central government became more important and gradually increased. The present study with its historical method tends to identify the effective factors behind such a relationship. The findings show that the factors such as protection of Eldiguzids from Seljuk, Abbasids Caliphate, the interventionist and expansionist strategy of Khwarazmian, invasions Georgian to Aran and Azerbaijan and the increasing greeds of Eldiguzids and their attempts to seize the Seljuk monarchy led to the formation of relations between Iraqi Seljuk and Eldiguzids. These factors, in accordance with their nature and the general atmosphere of the relationship between Iraqi Seljuk and Eldiguzids in two periods have caused changes in these relations from the stage of friendship to enmity.
