Kayqubad I of Shirvan

Kayqubad I was the 31st Shirvanshah, a son of Farrukhzad II, whose long reign was spent under Chobanid overlordship. When the Chobanid ruler Malek Ashraf demanded a daughter of the Shirvanshah in marriage, Kayqubad's son and co-ruler Kavus refused.

After Malek Ashraf invaded in winter 1347, the pair took shelter in Shirvan's strong castles. Kayqubad disappears from the sources soon afterwards and probably died between 1348 and 1356. The Keygubad Mosque is held to have been built on his order.
