1911 Encyclopædia Britannica/Abor Hills
ABOR HILLS, a tract of country on the north-east frontier of India, occupied by an independent tribe called the Abors. It lies north of Lakhimpur district, in the province of eastern Bengal and Assam, and is bounded on the east by the Mishmi Hills and on the west, by the Miri Hills, the villages of the tribe extending to the Dibong river. The term Abor is an Assamese word, signifying “barbarous” or “independent,” and is applied in a general sense by the Assamese to many frontier tribes; but in its restricted sense it is specially given to the above tract. The Abors, together with the cognate tribes of Miris, Daphlas and Akas, are supposed to be descended from a Tibetan stock. They are a quarrelsome and sulky race, violently divided in their political relations. In former times they committed frequent raids upon the plains of Assam, and have been the object of more than one retaliatory expedition by the British government. In 1893–94 occurred the first Bor Abor expedition. Some military police sepoys were murdered in British territory, and a force of 600 troops was sent, who traversed the Abor country, and destroyed the villages concerned in the murder and all other villages that opposed the expedition. A second expedition became necessary later on, two small patrols having been treacherously murdered; and a force of 100 British troops traversed the border of the Abor country and punished the tribes, while a blockade was continued against them from 1894 to 1900.
