The basis of national solidarity of the countries is rooted in a collection of material and divine elements which are known as the existential cause. Therefore, different nations and governments, in order to manifest themselves in the political facet as the independent units, need to improve, and even construct this vital element. Iran regarding its ancient history has passed through a long distance from this aspect, which has had ups and downs at times, as after the fall of Sassanid Dynasty, the existential cause of Iran waned for about nine hundred years. For a period of two hundred years, Iran was all obedient to the Great Islamic Caliphate in all aspects, and after the decomposition of Abbasid Caliphate,the Iranian states were ruled by the local independent rulers. After that, the fundamental element of the emergence of a new government in Iran and the Shiite sect becoming official, and its spread by Shah Ismael (1499-1524) led to the definition of the existential cause in Iran with reliance to the past ancient heritage and new content. The matter of the current study was to investigate the process of revival of Iran’s new existential cause in the form of ethnic symbolism oriented towards Shia, in this time section. The method of the current study is descriptive-analytical and the data collection instrument is the library-based study. The results of the study indicate that the Safavid, through strengthening elements such as the Persian language, the customs, and traditions, managed to establish the national solidarity.
