Treaty of Amasya

Timeline

1. 1554Erzurum · Ottoman EmpireAfter Suleiman's eastern campaign took Nakhchivan and elsewhere in 1554, both sides were exhausted by prolonged war. Tahmasp I refused a decisive battle; the shah's envoy Farrokhzad Beg brought valuable gifts to the Ottoman camp and proposed peace. Suleiman agreed to negotiate and planned to winter at Amasya to await further diplomatic contacts.
2. 1555Amasya · Ottoman EmpireOn May 29, 1555, both sides formally signed the treaty at Amasya. It demarcated the Ottoman–Safavid border: the Ottomans received Iraq, Baghdad, and access to the Persian Gulf, while the Safavids retained Azerbaijan, Tabriz, and the eastern Caucasus; Armenia and Georgia were divided equally. The Safavids pledged to stop cursing the first three Sunni caliphs and some Companions in prayer, while the Ottomans guaranteed Iranian pilgrims passage to Mecca, Medina, and Shi'i holy sites in Iraq.
3. 1555–1576Caucasus–Zagros border zone · Zagros MountainsBuffer zones were established after the treaty at Erzurum, Sharazor, Van, and elsewhere; Kars was declared neutral and its fortresses demolished. The treaty gave both empires roughly twenty years of relative peace: the Ottomans could redirect resources toward Europe and the Mediterranean, while the Safavids turned to internal consolidation and countering threats such as the Uzbeks. Georgia and the Kurdish regions were permanently divided, becoming a structural legacy of subsequent rivalry between the two empires.
