the predominant thought in historical texts during seljuq period in iran: ash'ari theology and practical wisdom

aggregation of ash'ari theology and pre-islamic practical wisdom of iranians is one of the characteristics of historiography during seljuq period. indeed, the iranshahri’s political thought had been revived and regarded as a practical model for seljuq sultans in siyar al-muluk (statesmanship manners of kings) and historical texts. the beginning of the nezam al-mulk’s ministry was also the extremity of the ash'ari theology in iran and influenced most of the historical writings. this article is going to answer these questions: why and how two thoughts of ash'ari and iranian practical wisdom appeared in the historiography of this period. do the presence and aggregation of two thoughts foreshadow a balance and counterpoise? or it was a metamorphosis or the domination of one over another?  the present survey will demonstrate that historical view of the historians during seljuq period is marked by some collaborative views of these two thoughts. in some cases, the historians of the seljuq period caused an evolution in pre-islamic thought of iranians and brought an islamic sense to it. in some other cases, regardless of the ash'ari’s views, they used the iranian practical wisdom to clarify the status of independent kingdoms.
