This interdisciplinary volume examines the longstanding and complex relations between Poland and Turkey from the 18th century to the present, exploring their cultural, diplomatic, political and economic dimensions. Drawing on extensive archival research across Europe and the Middle East, it presents a polyphonic narrative that highlights both shared interests and moments of divergence between the two states. The book analyses key themes such as public and cultural diplomacy, transcultural identities, stateless diplomacy, economic cooperation and contemporary foreign policy. It traces how these relations evolved despite periods of geopolitical instability and asymmetries of power, offering new insights into Eastern European and Middle Eastern entanglements. By reassessing Polish–Turkish ties through a longue durée lens, the book contributes to current debates on EU–Turkey relations and the relevance of historical models of cooperation in shaping contemporary international engagements. Rich in empirical material and combining historical, political and cultural analysis, the volume is essential reading for scholars and postgraduate students in international relations, Ottoman and East European history, political science and cultural diplomacy. Its fresh approach and innovative framework make it equally accessible to a broader audience, including policymakers, librarians and non-specialist readers interested in global history and regional connectivity.
