Tracing the history of the Ottoman and Safavid empires back to the Middle Period of Islamic history, this article focuses on their origins in the chieftaincies and the hybrid cultural formations of the Anatolian regions. While considering the inter/intracivilizational historical context of their respective rise to power, it is argued that the structural makeup of the empires differed primarily in their disparate forms of Sufi-knightly cultures, identified here as knightly-heroic (Ottoman) and millenarian-populist (Safavid), which is essentially tied to two distinctive (...) types of tribal political organizations: frontierchieftaincy (Ottoman) and sectarian-chieftaincy (Safavid). Although the original Ottoman and Safavid chieftaincies, based on the militant Ghazi and Qizilbash orders, dissolved once the roaming bands of warriors were replaced by more settled military formations in the course of long-term state-building processes, the influence of their Sufi-knightly cultural heritages is still manifest in modern Iranian and Turkish societies.
