3.1.1

The text as well as the Akbarnamah and the Iqbalnamah-i-Jahangiri state that Bengal was bounded on the south by the sea, on the north by hills (that is, those south of Nepaul, Sikkim, and Bhutan), on the east by hills (that is, those of Chittagong and Arakan), on the west by the Subah of Behar. During the reigns, however, of the Independent Musalman Kings (such as Ilyas Shah, and Alauddin Husain Shah in 1502 and his son and successor Nasrat Shah), the Musalman Kingdom of Bengal was more extensive than its geographical limits, and included northern portions of Orissa or Jajnagar, Kuch Behar, Kamrup or Western Assam with portions of Eastern Assam, and the whole of Upper Behar (a Governor to represent the Bengal Musalman King being posted at Hajipur opposite to Patna), and the eastern portions of South Behar including Sarkars Monghyr and Behar — (See J.A.S. No. 3, 1873, pp. 221-222). The whole of Orissa was conquered, and annexed to the Bengal Musalman Kingdom in the reign of Sulaiman Kararani, the last but one independent Musalman Afghan King in Bengal. When Bakhtiyar Khilji conquered Bengal, he ruled (ostensibly as Viceroy of the Musalman Emperor of Delhi, Kutbuddin Aibak) over portions of Dinajepur, Maldah, Rangpur, Nadiah, Birbhum, and Bardwan comprising what was then called Diyar-i-Lakhnauti, and also he held Behar (Tabaqat-i-Nasiri, p. 156).
