The Safavid Buffer: Co-Sectarian Rivalry in Early Modern Ottoman Diplomacy with Sunni Asia

Abstract This paper offers a new perspective on Ottoman-Safavid-Mughal relations in the early modern period by exploring the broader historical context of Swedish envoy Claes Rålamb’s report of the advice offered by the Ottoman chief mufti (the highest-ranking legal authority) to the court in 1657. Rålamb reported that the chief mufti had advised that the Ottoman court reject a Mughal offer to form a Sunni alliance against Iran and instead urged the court to protect the Shiʿi Safavids. By examining early modern inter-imperial Sunni relations in general and diplomatic exchange among these Muslim states between 1648 and 1656 in particular, this article challenges the prevailing narrative of sectarian differences driving political conflicts. I show that in the period following the Ottoman-Safavid peace treaty of 1639, the Ottomans regarded the Safavid state as a buffer polity that helped to secure their legitimacy against potential Sunni rivals in Central Asia and India. The article explores how a shared religious identity fueled rather than discouraged competition for legitimacy and supremacy among Sunni rulers in an increasingly interconnected early modern world, leading the Ottomans to align with their sectarian rivals.
