The Khorezm Mamun Academy and the Khorezm Regional Council of Spirituality and Enlightenment “Jaloladdin Manguberdi” Foundation jointly released a new book from the series “In Search of Traces of the Khorezmians ...”. The new edition is based on the Uzbek translation of the section of Abu Usman Minhojiddin ibn Sirojiddin about the history of the Anushtegin Khorezmshah dynasty in “Tabakati Nosiri”. It is noteworthy that the basic doctoral student of the Khorezm Mamun Academy Shokhrukhmirzo Ismailov took part in the translation of this work. “Tabakati Nosiri” is based on events that the author saw and witnessed, as well as on palace correspondence and historical documents. The historical work tells about the princes and princes of the Khorezmshah dynasty Anushtegin and their political activities. For this reason, in the Uzbek translation, the work is called “Princes from the Khorezmshah dynasty”. The historical significance of “Tabakati Nosiri” is that it critically assesses the history of the dynasty, which is practically not studied in the history of Khorezm today.
