Koca Sinan Pasha
He became agha of Janissaries in 25 February 1582 but dismissed his position with the effect of Koca Sinan Pasha. In 1582 he appointed as fourth visier by Grand Visier Siyavus Pasha and joined Ottoman forces during Safewid wars where he soon became second commander (serdar) of the war. He made Tebriz his military base and captured Ganja. He attended peaceful negotiations with Shah Abbas I and turned Istanbul with Safewid embassy. The Treaty of Ferhad Pasha of 1590 ending the Ottoman–Safavid War (1578–1590) (also called the "Treaty of Constantinople") was named after him.
