“ Early in the 17th century the raja Bali Narayan invoked the aid of the Ahoms of Upper Assam against the Mussulman invaders; after his defeat and death in 1637 the Ahoms dominated the whole district, and the Darrang rajas sank into petty feudatories. About 1785 they took advantage of the decay of the Ahom kingdom to try and re-establish their independence, but they were defeated by a British expedition in 1792, and in 1826 Darrang, with the rest of Assam, passed under British control. ”

“ In Mangaldai, on the other hand, most of the good rice land was settled about 1880–1890 when the subdivision had a population of 146 to the square mile, as against 42 for Tezpur; the soil is not favourable for tea, and the population is stationary or receding. In 1901 the population of the whole district was 337,313, showing an increase of 10% in the decade. The principal grain-crop is rice. ”
