Edessa

Edessa (; Ancient Greek: Ἔδεσσα, romanized: Édessa) was an ancient city (polis) in Upper Mesopotamia, in what is now Urfa or Şanlıurfa, Turkey. It was founded during the Hellenistic period by Macedonian general and self proclaimed king Seleucus I Nicator (r. 305–281 BC), founder of the Seleucid Empire. He named it after an ancient Macedonian capital. The Greek name Ἔδεσσα (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 Late Antiquity, it became a prominent center of Christian learning and seat of the Catechetical School of Edessa. During the Crusades, it was the capital of the County of Edessa. The city was situated on the banks of the Daysan River (Ancient Greek: Σκίρτος; Latin: Scirtus; Turkish: Kara Koyun), a tributary of the Khabur, and was defended by Şanlıurfa Castle, the high central citadel. Ancient Edessa is the predecessor of modern Urfa (Turkish: Şanlıurfa; Kurdish: Riha; Arabic: الرُّهَا, romanized: ar-Ruhā; Armenian: Ուռհա, romanized: Urha), in Şanlıurfa Province, Turkey. Modern names of the city are likely derived from Urhay or Orhay (Classical Syriac: ܐܘܪܗܝ, romanized: ʾŪrhāy / ʾŌrhāy), the site's Syriac name before the re-foundation of the settlement by Seleucus I Nicator. After the defeat of the Seleucids in the Seleucid–Parthian Wars, Edessa became capital of
