Kilij Arslan I

Kilij Arslan was the son of Suleiman Shah, founder of the Anatolian Seljuk state. After his father's death he was held in Isfahan, and after Malik-Shah's death in 1092 he returned to Nicaea and became sultan. In 1096 he destroyed the first crusading bands, the so-called People's Crusade, near Nicaea.

In 1097 the main army of the First Crusade took Nicaea and defeated Kilij Arslan at Dorylaeum, and he moved his capital to Konya. But in 1101 he routed one new crusading army after another in Anatolia. In 1107 he drowned in the Khabur river during a battle against the Great Seljuks.
