Kayki Mustafa Bey

Kayki Mustafa Bey, also Kaykı Bey (قيقى بك), 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.^[2] 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 garrison fell, and Asafi was captured by the Safavid Kizilbas.^[3]

Asafi was kept in captivity in Qazvin and Isfahan, but was released in 1585, finally rejoining Osman Pasha.^[4]
