Dibrugarh district

Dibrugarh district (Pron:ˌdɪbru:ˈgor:) is a district in the state of Assam in India. The district headquarters are located within the city of Dibrugarh.

Etymology
Dibrugarh derived its name from Dibarumukh (as a renowned encampment of Ahoms during the Ahom-Chutia war). Either the name “Dibru” evolved from Dibaru river or from the Bodo-Kachari word “Dibru” which means a “blister” and “Garh” meaning "fort". The Bodo-Kacharis add the prefix “Di-” (which means “water”) wherever there is small stream, a river, or a large river in a town or city.

16th century
The region was part of the Chutia Kingdom until the Ahoms occupied it in the year 1523 AD. The Chutia army under the generals Kasitora, Alangi Chetia and Borpatra fought against the Ahoms at Dibrumukh, but were defeated. After the Ahoms captured Sadiya in 1524 AD, bringing an end to the Chutia kingdom, the Ahom king Suhungmung placed an official named Chaolung Shulung to control the region.

Since the defeat of the royalists troops at Amaratali of Dibru in 1787 A.D. in the reign of Gaurinath Singha, during the Moamoria rebellion this region came under the Moamarias who also formed there a dominant religious community. Dibrugarh became a separate district when it was split from Lakhimpur on 2 October 1971. On 1 October 1989 Tinsukia district was split from Dibrugarh.
