Starting from the 6th century A.H., and especially starting from the Mongol era onward, along with the flourishing of historiography, historical shahnameh-composition also became a point of interest, and shahnamehs appeared with the aim of recording historical events. In the composition of these shahnamehs, Ferdowsi’s Shahnameh was like a model for the shahnameh-writers, and due to this the spirit of the ruler had a direct or an indirect affect on the historical compositions. This is despite the fact that the Mongol myths and epics had come in to the compositions of this era, which was dependent on the subject of these shahnamehs, which was the Mongol people and the rulers, which had rose from there. Examination of the content of these versified histories can assist in shedding light on some new dimensions of the Iranian literary history, as well as the historical changes taking place in the given work. Among these, some of the poetic works that are still remaining in the manuscript form have more new materials. The Chengizid Shahnameh and the Shahanshahnameh are the two important examples of such shahnamehs, which have been composed about the history of the Mongols. The given article introduces, breaks-down, and analysis these two works in order to show the level of the shahnamehs-composition during the period discussed.
