No empire or a regional power has helped mold the socio-political and religious landscape of a country as the Ottoman Empire and its heir (the Republic of Turkey) have helped shape modern Lebanon, yet no contemporary study has examined Lebanon-Turkey relations back to Ottoman rule of Lebanon. As such, the understanding of this historic and contemporaneous relationship is deficient. This text fills this gap, examining patterns and shifts in Lebanon-Turkey relations within the context of regional and international politics from Ottoman rule to Turkey's AKP-led governments. This comprehensive account of Lebanon-Turkey relations-grounded in layers of cultural, political, demographic, economic, and sectarian complexities and changes across centuries-analyzes the developments and dynamics that have helped shape modern Lebanon and its confessional system and politics. It underscores the misconceptions and lessons learned from this long-term relationship, locating Lebanon-Turkey relations along a historical continuum.
