Seljuk Ardabil: From a Frontier City to a Center of Sufism and Urban Trade, with Emphasis on Its Peak Flourishing and the Groundwork for the Safavid Rise

<jats:p>This study examines the city of Ardabil during the Seljuk period (1038–1194 CE) as a historical turning point in the trajectory of urban transformations from the advent of Islam to the rise of the Safavids. Focusing on the question of “how Ardabil was transformed from a frontier city into a religious-commercial center,” the study demonstrates that the Seljuks, through the policies of Niẓām al-Mulk, a bureaucratic-religious administrative structure, organized urban planning—including the congregational mosque, bazaar, madrasas, dams—a market-oriented economy based on silk, textiles, and metalwork, the organization of guilds and the office of the muḥtasib, and support for Sufism through Sufi lodges and endowments, elevated Ardabil into a multifunctional urban center. These transformations paved the way for the emergence of Shaykh Ṣafī al-Dīn Ardabilī and the Safavid family. The Seljuks created a bridge between early Islam, characterized by Sunni-Abbasid structures, and the Safavid state, marked by Shiʿi-national state formation. Ardabil’s legacy in Shiʿi state-building included local-national identity, the endowment-based structure, militarized Sufism, the Turkic language, and a model of urban planning. Drawing on historical, geographical, and endowment sources, this study presents Seljuk Ardabil as a successful model of a secondary city in shaping major historical transformations.</jats:p>
