Europe was divided into states whose rulers were involved in petty territorial disputes. In 1070 Jerusalem, the Seljukian Turks were gaining power and saw it as a threat to Christendom. In 1070 Jerusalem was taken, and in 1071 Diogenes, the Greek emperor, was defeated and made captive at Mantzikert. Asia Minor and all of Syria became the prey of the Turks. Antioch succumbed in 1084, and by 1092 remained in the possession of the Christians.
