It was founded during the Hellenistic period by Macedonian general and self proclaimed king Seleucus I Nicator (), founder of the Seleucid Empire. He named it after an ancient Macedonian capital. The Greek name (Édessa) means "tower in the water". It later became capital of the Kingdom of Osroene, and continued as capital of the Roman province of Osroene. In Lat

Circesium ( ', ), known in Arabic as al-Qarqisiya''', was a Roman fortress city near the junction of the Euphrates and Khabur rivers, located at the empire's eastern frontier with the Sasanian Empire. Procopius calls it the "farthest fortress" (φρούριον ἔσχατον) of the Romans. It was later conquered by the Muslim Arabs in the 7th century and was often a point of contention between various Muslim states due to its strategic location between Syria and Iraq. The modern town of al-Busayra corresponds with the site of Circesium.
