Treaty of Constantinople (1590)

[4] With the empire beleaguered on numerous fronts and its domestic control plagued by civil wars and court intrigues, the new Safavid king Abbas I, who had been placed on the throne in 1588, opted for unconditional peace, which led to the treaty.

At the time the war commenced, the Safavid Empire was in a chaotic state under its weak ruler, Mohammad Khodabanda.

In the resulting fighting, the Ottomans had managed to take most of the Safavid provinces of Azerbaijan (including the former capital Tabriz), Georgia (Kartli, Kakheti, eastern Samtskhe-Meskheti), Karabagh, Erivan, Shirvan and Khuzestan,[1] despite Mohammad Khodabanda's initially successful counterattack.

[3][5] When Abbas I succeeded to the throne in 1588, the Safavid realm was still plagued by domestic issues, and thus the Ottomans managed to push further, taking Baghdad during that year and Ganja shortly after.

Abbas I would use the time and resources which resulted from the peace on the main front with the Ottomans, to successfully deal with the other issues (including the Uzbeks and other revolts), while waiting for a suitable moment to regain his possessions.
