(signed on 26 September 1618 in Sarab) By the treaty of Nasuh Pasha in 1612 Ottoman Empire had agreed to turn back Caucasus and Northwest Iran to Safavid Persia.
Safavid Empire on the other hand agreed to pay an annual tribute of 200 loads of silk as a part of reparations.
[1] However, Shah Abbas I the Great of Persia refused to pay the tribute.
The Ottoman commander in chief Grand Vizier Öküz Kara Mehmed Pasha tried to capture Yerevan (modern Armenia) which was recently abandoned by the treaty of Nasuh Pasha, but he lifted the siege after 44 days as no improvements were booked.
[3] This treaty proved that a stalemate between Ottoman Empire and Safavid Persia had been reached and neither side might gain substantial territories in the long run.
