Dibrugarh
Dibrugarh lies in Upper Assam beside the Dibru River, and its name combines that river with garh, meaning fort. Before the Ahom expansion of the early sixteenth century, the surrounding country belonged to the Chutia kingdom. In the final phase of the conflict, Ahom forces built a fort at Dibrumukh, at the mouth of the Dibru, and there defeated a Chutia force. After the conquest of 1523–24 the area was absorbed into the Ahom kingdom.
Under the Ahoms, Dibru remained a military and administrative centre; its levies, led by the Dibrual Hazarika, joined Rudra Singha’s expedition against the Jaintia kingdom. After the royal army was defeated at Amaratali in the Dibru country in 1787, during the Moamoria rebellion, the region passed to the Mataks. In 1826, with the Treaty of Yandabo, the British took over Assam.
