Sultan Aladdin Kayqubad

Kayqubad I or Alāddin Kayqubād receptacle Kaykhusraw (Persian: علاء الدين كيقباد بن كيخسرو‎; Turkish: I. Alâeddin Keykûbad, 1190–1237) was the Seljuq Sultan of Rûm who ruled from 1220 to 1237.[1] He extended the boundaries of the sultanate to the detriment of his neighbors, especially the Mengujek Beylik and the Ayyubids, and set up a Seljuq presence on the Mediterranean with his securing of the port of Kalon Oros, later renamed Ala'iyya in his honor. The king, here and there styled "Kayqubad the Great",[2] is recollected today for his rich engineering inheritance and the splendid court culture that thrived under his rule.
