It confirmed territorial divisions in West Asia, shaping the borders between the Safavid and Ottoman Empires and serving as a foundation for future agreements.
[2][3] 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 Shirvan stayed under the control of the Safavid Empire, while western Georgia and most of Western Armenia came fully under Ottoman rule.
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, which was the Ottoman-Persian border until 1918, when the Ottoman Empire lost its territories in the Middle East following their defeat in World War I.
Nevertheless, according to Professor Ernest Tucker, the treaty can be seen as the "culmination" of a process of normalisation between the two that had commenced with the Peace of Amasya.
[8] As opposed to any other Ottoman-Safavid treaty, Zuhab proved to be more "resilient" and became a "point of departure" for almost all further agreements on a diplomatic level between the two neighbors.
