Kayqubad I
Seljuq sultan of Rûm Kayqubad I conquered Alaiye (Alanya) and formed a naval arsenal there. Alanya became the homeport of the Seljuk fleet in the Mediterranean Sea. Kayqubad I later formed a fleet in the Black Sea based in Sinope (Sinop), which, under the command of Amir Chupan, conquered parts of the Crimean peninsula and Sugdak on the Sea of Azov (1220–1237).
