The book begins with the conquests of Muhammad of Ghor (1149-1206), and ends abruptly in 1434.[2] Several earlier royal chroniclers had written texts describing the 13th-15th century history of the Delhi Sultanate. For example, Minhaj-i-Siraj covered the period up to 1259 in his Tabaqat-i Nasiri, Ziauddin Barani covered 1259-1356, and Shams-i Siraj Afif covered 1356-1388.
