Kayki Mustafa Bey

Kayki Mustafa Bey, also Kaykı Bey, was an Ottoman army officer who played a role in the Ottoman–Safavid War (1578–1590).
From 1579, Kayki Mustafa Bey together with Asafi attempted to protect the recently conquered Shirvan against the counter-attacks of the Safavids. Osman Pasha ordered them to reinforce the fortifications of Qabala castle. In 1581, the Qabala castle was captured following a Safavid ruse, in which they used fall letters and Korans to suggest the war had ended. The Ottoman garisson fell, and Asafi was captured by the Safavid Kizilbas.
Asafi was kept in captivity in Qazvin and Isfahan, but was released in 1585, finaling rejoining Osman Pasha.
