The Chronological Process of Substituting Military Governments of the Levant from Tutush I till Saladin

Since the formation of Seljuks in the Levant, this region was subject to unrest, which continued the chaotic trend of the post-Hamdanid. What took place in the Levant in the Seljuk period was a series of replacing the governments by the soldiers of the same dynasty one after the other from 478 till 570 A. H. This research aimed to answer this question: What was the process of substituting governments in this period? To this goal, the reasons for the rise and fall of the Levant's governments and the records of substitute dynasties had to be analyzed. By using the quantitative historical method, the procedure of these substitutions was mapped. According to this study, the chronological process of substituting the governments had increased over time. The former disturbs were managed to be settled and the short-term rulers -inheritances of Arab tribes- to be altered by long dynasties, such as the Zengid and Ayyubid dynasties.
