32.3

Sultan Nasiruddin, eldest son of Emperor Altamsh, invaded Lakhnauti, whilst Ghiasuddin was engaged at Kamrup and Bang (East Bengal), and fought a battle with Sultan Ghiasuddin, on the latter's return, and killed the latter, and succeeded to the rule over Bengal in a semi-sovereign capacity, with the approval of his father, Emperor Altamsh. It is stated that Sultan Ghiasuddin extended and consolidated the Moslem sovereignty in Bengal, and extended his empire over Jajnagar (Orissa), Bang (East Bengal), Kamrud (or Kamrup, Western Assam), and Tirhut (see Tabaqat-i-Nasiri, Pers. text, p. 163.) Minhajus-Siraj, Author of Tabaqat-i-Nasiri who visited Lakhnauti shortly after in 641 A.H. and appreciated the material improvements effected by Ghiasuddin, pays him a high tribute (Pers. text, p. 161), a tribute which in 627 A.H. Emperor Altamsh had also paid to the memory of this good and great sovereign, by decreeing that Ghiasuddin should in his grave be styled as a Sultan. Amongst his public works, Tabaqat-i Nasiri mentions that he founded the Fort of Baskot (Basankot near Gaur), established mosques, and Public Halls, &c. introduced the Khutbah and the coin in his own name, and to some extent arrogating to himself the sovereign power, he ruled over this country. And when the throne of Delhi by the accession of Sultan Shamsu-d-din Altamsh received eclat in the year 622 A.H., the latter marched with his forces to Behar, and invaded Lakhnauti.
