History
The plains, foothills, and lower hills of the district were part of the Chutia kingdom, while the higher hills were inhabited by the Mishmis. Chidu-Chimri Fort, a hill fort/settlement, and Barnagar, the capital of the Chutia period, are some of the important historical sites of the district. After the Ahom defeat of Chutias, the Mishmis were permitted to settle in the plains, and a border was drawn near the present-day Arunachal Pradesh-Assam state borders. The Sadiya Serpent Pillar, which was originally constructed by the Chutias at the gate of their capital city on the banks of the Dikrong River, marked this border.
In June 1980, the Dibang Valley district was created from part of the Lohit district.[3] On 16 December 2001, the Dibang Valley district was bifurcated into Dibang Valley district and Lower Dibang Valley district.[3]
