Historiography in every era is the complete mirror of that era. One of the brightest eras in Iran history is Safavid era. In this era, Iran history was involved with the greatest changes in different political and cultural arenas. In this era, Safavids with making official of Shia religion, not just took the advantage of ideology for political domination, but they also changed Iran’s ideological and religious face. Historiography was affected a lot by this great event and it even became the complete mirror of it’s era. In fact, the main objective of this research which is prepared by analytical and descriptive method and based on library resources is to answer this important question: What was the effects of changes in religious views in Safavid era on public historiography? Primary investigations show that although Safavid public historiography is the continuation of Teimuri historiography in the method and style, but religous changes also affected this era’s public historiography. Public history beside Safavid political and cultural constitutions, established Shia culture in this era.
