The impact of İranian culture on the formation of Shia

The emergence of a sect and the formation of its creeds can be explained by many factors. One of them is the role played by the cultural environment, in which the sect emerged and evolved. To understand Shia truly, It?s important to know the role of ancient Iranian culture on the formation and the improvement of Shia. So, the impact of Iranian culture on the formation of Shia constitutes our research.We researched how Iranian culture affected Shia on the period of its formation by using some classical sources of the History of Islam, the History of Sects and some books about History of Iranian and its culture written by authors of Ahl al-Sunnah and Shia. We examined on Mitraism, Zoroastrianism, Manicheism, Mazdakism from Iranian religions before Islam by giving informations about their beliefs and practices, and discoursed how some principles of these religions passed on Shia. We researched on occurring of Imamate, Mahdism, Raj?a, Bada, Hulul-Tanasukh, Taqiyyah which are basic beliefs and principles of Shia, and the impact of Iranian culture in this period. To observe the signs of Iranian culture in Shia, we followed the religious and cultural lives of Shiites in cities of Iran. (etc. Shiraz, Yazd, Isfahan, Ray, Qum, Tehran, Tabriz)We concluded that Iranian culture affected some basic beliefs and principles of Shia during its formation in this research. At the same time, we observed that the influence of Iranian culture on Shia was not only limited in the period of its formation, but also has continued to affect Shiite beliefs and practices until now. We understand that it is necessary to research the relation between Iranian culture and Shia, not only for basic Shia?s beliefs and principles, but also on account of other Shia?s beliefs and practices well-rounded by new researches showing how Shia has been affected from ancient religions and cultures of Iran.
