may 17, 1638 - Treaty of Qasr-e Shirin
Description:
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.
