History:

The name of the Low Dibang Valley district comes from the powerful Dibang River, which flows through the center of the district and finally into Brahmaputra. Prior to 1914, the area was part of the Rakinpur area. In 1919, the Central and Eastern parts were renamed Sadiya Frontier Tracts. The Lower Divan Valley area has been removed from the undivided Divan Valley area at Rowing's headquarters under the 1980 District Law Reorganization Amendment that came into effect on December 16, 2001. The area is known to cover the most dense green forests, with nearly 80% of its area designated as protected forests, reserves, or unclassified state forests. The Lower Dibang Valley region, headquartered in Roing is the smallest of the 15 provinces of Arunachal Pradesh.
