archaeologists found coins struck in his name in Raqqa, dated to 1058, buried under a collapsed wall in the city's congregational mosque. Remains of a workshop under the same wall may also indicate that restoration work was started on the mosque around the same time. However, it appears that this work was stopped soon after it started. A possible reason is Mani's sudden death in 1062, which left the Numayrids without an effective ruler and dealt a huge blow to their overall political power. Second blossoming Raqqa experienced a second blossoming, based on agriculture and industrial production, during the Zangid and Ayyubid dynasties during the 12th and the first half of the 13th century. The blue-glazed Raqqa ware dates from this time. The still-visible Bāb Baghdād (Baghdad Gate) and the Qasr al-Banāt (Castle of the Ladies) are notable buildings of the period.

Between 1800 and 1803, the province was governed by the famous Milli Timur Paşa of the Kurdish Milli tribe. From the 1820s, Raqqa was a place of wintering for the semi-nomadic Arab 'Afadla tribal confederation and was little more than its extensive archeological remains.
