year. The chronicle of Pseudo-Dionysius indicates that workmen were brought from all over Mesopotamia to work on the construction, hinting at the monumental scale of this project. According to al-Tabari, the plan of al-Rafiqah was basically the same as that of Baghdad: it was built with "the same gates, intervallum (fuṣūl), squares, and streets" as the recently-built Abbasid capital. In practice, there were some significant differences between the two: al-Rafiqah was somewhat smaller but more heavily fortified than Baghdad, and its shape was more elongated along a north-south axis instead of the famously round city of Baghdad. Construction continued at al-Rafiqah at least until 774-5, when al-Mahdi was again sent to check on its progress. At least at the beginning of the construction work on al-Rafiqah, the indigenous residents of Raqqa were hostile to the military settlement – they expected a rise in their own cost of living. The newcomers were soldiers from Khorasan, in contrast to the Christians and Arabs who lived in the old city. By 785, the old market of Raqqa had probably become physically too small to serve the needs of both it and al-Rafiqah. That year, Ali ibn Sulayman, the city's governor, moved the market from the old city of Raqqa to the agricultural land between the two cities. This probably marks the start of al-Muhtariqa, the industrial and commercial suburb located between the two (see below). (The old market, associated with the Umayyad caliph Hisham, had been just north of the old city, outside the Bāb al-Ruhā' – near the later industrial site of Tall Aswad.) Raqqa and al-Rāfiqah merged into one urban complex, together larger than the former Umayyad capital, Damascus. In 796, the caliph Harun al-Rashid chose Raqqa/al-Rafiqah as his imperial residence. For about 13 years, Raqqa was the capital of the Abbasid Caliphate, which stretched from Northern Africa to Central Asia, but the main administrative body remained in Baghdad. The palace area of Raqqa covered an area of about north of the twin cities. One of the founding fathers of the Hanafi school of law, Muḥammad ash-Shaibānī, was chief qadi (judge) in Raqqa. The splendour of the court in Raqqa is documented in several poems, collected by Abu al-Faraj al-Isfahāni in his "Book of Songs" (Kitāb al-Aghāni). Only the small, restored so-called Eastern Palace at the fringes of the palace district gives an impression of Abbasid architecture. Some of the palace
