Review of National Convergence in the Achaemenid Empire Based on the Study of Relieves, Inscriptions and Architecture of Persepolis

Persepolis is from the relics of the Achaemenid era in southern Iran, where the elements of architecture, decorative, and written texts are studied from various angles. The purpose of this research is to identify and identify the elements of the element of collective identity as well as the symbols of the national integrity in the elements mentioned above. The motifs used in the construction of Persepolis, alongside the great structure, have been directly and implicitly indicative of the communist spirit or the convergence of the builder kings. The question that the present paper tries to answer is that, despite the fact that in the Achaemenid world of different nations, the Persian rulers have elements and components in Persepolis (including structures, motifs and Inscriptions), which made the nations a subsidiary part of the political sovereignty of the empire towards the establishment of a global state? It seems that the Achaemenids in the use and adaptation of the artistic and technical elements of the nations in the Persepolis, in addition to the aspect of aesthetics, have also considered their cultural-political dimension. All of these elements and artistic elements have, in a way, expressed the notion of collective identity in a whole and in the sense of the empire. In general, all elements were served in such a way that their visitor was considered in a perfect agreement with other nations and equal, and considered for himself and his nation a single identity. This issue was very influential in the coherence of the empire, and the Achaemenid kings also knew about it. The method of this research is based on library studies, walking surveys of relives and descriptive-historical analysis.
