Raqqa (Arabic: ٱلرَّقَّة, romanized: ar-Raqqah, also al-Raḳḳa) is a city in Syria on the North bank of the Euphrates River, about 160 kilometres (99 miles) east of Aleppo. It is located 40 kilometres (25 miles) east of the Tabqa Dam, Syria's largest dam. The Hellenistic, Roman, and Byzantine city and bishopric Callinicum (formerly a Latin and now a Maronite Catholic titular see) was the capital of the Abbasid Caliphate between 796 and 809, under the reign of Harun al-Rashid. It was also the capital of the Islamic State from 2014 to 2017.
