This was the second great historical work of al-Baladhuri, of which he is said to have written forty parts when he died. Of this work the eleventh book has been published by Wilhelm Ahlwardt (Greifswald, 1883), and another part is known in manuscript (see Journal of the German Oriental Society [Zeitschrift der Deutschen Morgenländischen Gesellschaft], vol. xxxviii, pp. 382-406).
The modern publication history of the 'Ansab' is a complicated one; several teams of editors have worked on separate, rival editions. The only complete edition is the new Damascus one (Dar al-Yaqazah, 1996-), published in 25 volumes.
