Pursuant to the death of Sultan Alaeddin Keykubad, his son, Giyaseddin Keyhusrev II ascended the throne among the competitions of the commanders and beys. This ruler who had a weak character had been under the domination and influence of the commander Sa'deddin Kopek. Due to his role in the enthronement of the sultan, his cunning mind and his orientation of the ruler with a strange character in accordance with his desires, Sa'deddin Kopek got rid of great statesmen that he considered as rivals to him. Therefore, he left the Seljuk State without any leader. Sa'deddin Kopek had the desire to annihilate all his rivals among the staff officials that could oppose to him and then to ascend the throne of the Seljuk State. However, when his tricks and intrigues were revealed, he was immediately executed (1239). Celaleddim Karatay had played the leading role in the annihilation of Sa'deddin Kopek. Upon the domination of statesmen like Celaleddin Karatay, the situation of the state had improved to a certain degree, but they could not eradicate all the political and administrative weaknesses. The rebellion of Babai Ilyas who was a Turkmen sheikh could only be suppressed with great difficulties and this rebellion showed that the Anatolian Seljuks State was on the verge of decline.
