Ottoman-Safavid relations after 1639 have been dismissed as marginal and assumed not to have produced sufficient documentation to facilitate a study, wherefore the subject matter has lacked even an introduction providing basic facts, let alone a comprehensive treatment.This book establishes for the first time the mission exchanges, correspondence, negotiations, and borderland encounters by drawing on scattered and hitherto-untapped archival documents, chronicle entries, and travelogues by the Ottomans, Safavids, and Europeans.Working up the information unearthed thereby, it reconstructs the groundwork of these dealings, highlights trends, and contextualizes the facts. The book refutes the assumption that the mid-seventeenth-century interstate scene of the Middle East was eventless, and documents how the parties in question intensively bargained, displayed goodwill, made demands, delivered threats, presented displays of might, asked for privileges as well as concessions, and brought in third parties to their relations, all within an unequal relationship in strength, hierarchy, order of precedence, ranks, and protocol.
