Abbas I of Persia
The Ottoman–Safavid War of 1603–1618 consisted of two wars between Safavid Persia under Abbas I of Persia and the Ottoman Empire under Sultans Mehmed III, Ahmed I, and Mustafa I. The first war began in 1603 and ended with a Safavid victory in 1612, when Persia regained and reestablished its suzerainty over the Caucasus and Western Iran, which had been lost at the Treaty of Constantinople in 1590. The second war began in 1615 and ended in 1618 with minor territorial adjustments.
