Anbar (town) — Wikipedia

Anbar (Arabic: الأنبار, romanized: al-Anbār, Syriac: ܐܢܒܐܪ, romanized: Anbar) was an ancient and medieval town in central Iraq. It played a role in the Roman–Persian Wars of the 3rd–4th centuries, and briefly became the capital of the Abbasid Caliphate before the founding of Baghdad in 762. It remained a moderately prosperous town through the 10th century, but quickly declined thereafter. As a local administrative centre, it survived until the 14th century, but was later abandoned. Its ruins are near modern Fallujah. The city gives its name to the Al-Anbar Governorate.
