Dadenggre Civil Sub-Division is one of the first 4 sub-divisions created in the state of Meghalaya. It came into existence on August 17, 1982. It is located at the extreme north-western part of Meghalaya and has its borders with Goalpara and Dhubri districts of Assam to the north and west respectively, with other parts of West Garo Hills to the south-east, South West Garo Hills, East Garo Hills and North Garo Hills. It is well connected by road to other parts of Garo Hills, and is approximately 54 kms from the district headquarters of West Garo Hills, Tura. To lend momentum to the developmental activities in this administrative unit, three community development blocks have been created, namely, Dadenggre, Selsella and Tikrikilla Development Blocks.

The physical surface of Dadenggre is made up of dissected hills, peneplain-like valleys and flood plains. The flood plains occupy the parts along the fringes of the sub-division bordering Assam. The atmospheric condition is of a humid sub-tropical character, and the average rainfall received ranges from 3200- 3800 mm, with the months of June and July registering the highest amount of rainfall. The soil is acidic, and the non-acidic fine-grained soil is found only along the narrow stretch along the banks of the river Brahmaprutra and its tributaries. The three notable rivers of the sub-division are Ringgi, Ditti and Jinjiram. Apart from these two rivers, there are numerous creeks, rivulets and streams across the Sub-Division.

Agriculture is the main occupation of the people of Dadenggre sub-division. The traditionally cultivated crops are winter potato, spring paddy, rapeseed and mustard, tobacco, winter paddy, soyabean, sweet potato, cotton, ginger, chillies, sesamum, wheat, gram, pulses, pea, cow pea, lentil, sugarcane, linseed, turmeric, areca nut, citrus fruits (Khasi Mandarin and Assam Lemon), finger millet, foxtail millet, pearl millet, jhum paddy, autumn paddy, jute, mesta, banana, tapioca, papaya, maize and pine apples. Due to the vagaries associated with cashew plants, farmers are now gradually shifting towards growing rubber which has proved to be comparatively more profitable.

The main inhabitants of the Sub Division, the Garos, are one of the three major tribes of the state of Meghalaya. The other tribes that inhabit parts of the Sub-Division are the Koch, Bodos, Rabhas and Hajongs.
