Treaty of Kerden

The treaty was signed in Kerden (a location^[4] near Qazvin, Iran). The representatives were Hasan Ali Haji (Afsharid side) and Mustafa Nazif (Ottoman side).^[5]

2. The Ottomans agreed to stop opposing the Afsharid dynasty as the rulers of Iran.^[6]
3. The Ottomans also agreed to allow the Iranian hajis (pilgrims) to Mecca (then under Ottoman control).

Both sides now saw that neither could win a decisive victory, and that continuation of the war would only drain their strength. Nadir Shah hoped to use his victory at Baghavard to secure a favourable settlement, finally abandoning his claims on behalf of the Ja'fari sect, and instead concentrating on the demand that all of Iraq, including Baghdad, Basra and the Shi'i holy places of Najaf and Karbala, be turned over to him along with the Kurdish area of Van. A series of letters and exchanges of ambassadors followed, and eventually an agreement was hammered out on 4 September 1746, by which the Qasr-i-Shirin treaty boundaries were restored without change, with provisions made for the exchange of prisoners, as well as the exchange of ambassadors once every three years. Nadir Shah thereby abandoned all his former demands and the Ottomans accepted peace in accordance with the earlier agreements.
