The Third International Süleymaniye Symposium explored the Köprülü Era (1656-1710) in Ottoman history, emphasizing new sources and approaches. Scholars from Turkey, Europe, and the U.S. convened to examine the Köprülü grand viziers’ careers and times. In the current special focus section, Yasir Yılmaz, Halef Cevrioğlu, Elizabeth Lobenwein, Georg B. Michels, and Christopher Whitehead offer innovative perspectives, drawing on brand new archival material. We advocate for a comparative approach to the Ottoman grand vizierate, highlight the significance of Habsburg archives in Ottomanist scholarship, debunk new short-term and long-term historical dimensions in the making of the family, and ask new questions about how we should interpret the Köprülü expansionism.
