Treaty of Zuhab


The Treaty of Zuhab, also called Treaty of Qasr-e Shirin, was an accord signed between the Safavid Empire and the Ottoman Empire on May 17, 1639. The accord ended the Ottoman-Safavid War of 1623–1639 and was the last conflict in almost 150 years of intermittent wars between the two states over territorial disputes. It can roughly be seen as a confirmation of the previous Peace of Amasya from 1555.
The treaty confirmed the dividing of territories in West Asia priorly held by the Safavids, such as the permanent parting of the Caucasus between the two powers, in which East Armenia, eastern Georgia, Dagestan, and Azerbaijan stayed under the control of the Safavid Empire, while western Georgia and most of Western Armenia came fully under Ottoman rule. It also included all of Mesopotamia being irreversibly ceded to the Ottomans, as well as Safavid-controlled eastern Samtskhe, making Samtskhe in its entirety an Ottoman possession.
Nevertheless, border disputes between Persia and the Ottoman Empire did not end. Between 1555 and 1918, Persia and the Ottomans signed no less than 18 treaties that would re-address their disputed borders. The exact demarcation according to this treaty would permanently begin during the 19th century, essentially laying out the rough outline for the frontier between modern day Iran and the states of Turkey and Iraq Nevertheless, according to Professor Ernest Tucker, the Zuhab treaty can be seen as the "culmination" of a process of normalisation between the two that had commenced with the Peace of Amasya. As opposed to any other Ottoman-Safavid treaty, the Zuhab treaty proved to be more "resilient", and it became a "point of departure" for almost all further agreements on a diplomatic level between the two neighbors.
