Although imperium along the southern coast of Asia Minor had been assigned to various propraetors beginning in 104 BC, it was only annexed to the Roman Republic as a province in 64 BC by Pompey as a consequence of his victory in the Third Mithridatic War.
Further subtractions and additions to its territory were made until AD 72, after which its boundaries were unchanged until Diocletian divided the province into three parts: Cilicia Prima, under a consularis; Cilicia Secunda, under a praeses; and Isauria, also under a praeses.
Although passing into Byzantine control following the division of the Empire into Western and Eastern parts, these later provinces were lost in the seventh century as a result of the Muslim conquest of the Levant.
