The immediate impact of the Byzantine defeat seems to have been negligible; losses were heavy but not unbearable, and the level of devastation of the region seems not to have been excessive. In material terms, there is therefore little to distinguish the defeat at Kopidnadon from the "typical" Arab raid.[4][7] It marks, however, a recommencement of large-scale border warfare after the relative lull since 782,[8] which continued unabated until Harun's death in 809 and the subsequent Abbasid civil war.[9]
