Early Islamic period In the 7th century Cilicia was invaded by the Muslim Arabs. The area was for some time an embattled no-man's land. The Arabs succeeded in conquering the area in the early 8th century. Under the Abbasid Caliphate, Cilicia was resettled and transformed into a fortified frontier zone (thughur). Tarsus, re-built in 787/788, quickly became the largest settlement in the region and the Arabs' most important base in their raids across the Taurus Mountains into Byzantine-held Anatolia.
