BIOGRAPHICAL DOSSIER
Life and historical role
Life and political setting
Kilij Arslan was a son of the Seljuk ruler Suleiman ibn Qutalmish. Released after the death of Malik-Shah, he re-established the Anatolian Seljuk sultanate in 1092 and made Nicaea his principal centre. His early rule was shaped by rivalry with the Danishmendids and other Turkish powers before the arrival of the crusading armies altered the political balance of Anatolia.
Career during the Crusading era
He destroyed the poorly organised crusading forces at Civetot in 1096 but initially underestimated the size of the main army in the following year. Nicaea surrendered to Byzantium, and his attack at Dorylaeum failed after the arrival of crusader reinforcements. In 1101 he cooperated with other Turkish forces to defeat several new crusading columns in central Anatolia.
