Barak Valley
India
Barak Valley (Bengali pronunciation: [bɔɾak upɔt̪ːɔka]) is the southernmost region and administrative division of the Indian state of Assam. It is named after the Barak River, whose watershed roughly forms its northern border. The Barak valley consists of three administrative districts of Assam: Cachar, Karimganj, and Hailakandi. The main and largest city is Silchar, which seats the headquarter of Cachar district and also serves as administrative divisional office of Barak valley division. The valley is bordered by Mizoram and Tripura to the south, Bangladesh and Meghalaya to the west and Manipur to the east respectively. Once North Cachar Hills was a part of Cachar district which became a subdivision in 1951 and eventually a separate district. On 1 July 1983, Karimganj district was curved out from the eponymous subdivision of Cachar district. In 1989, the subdivision of Hailakandi was upgraded into Hailakandi district. As this Bengali speaking region is situated in the northeastern corner of the greater Bengal, was once identified as "Ishan Bongo"(Northeastern Bengal) in local folklore. The name "Barak" is derived from the Dimasa words 'Bra' and 'Kro'. Bra means bifurcation and Kro upper means portion/stream. The river Barak is bifurcated near Haritikar in the Karimganj district in to Surma River and Kushiyara River, respectively. The upstream of this bifurcated river was called "Brakro" by the Barman Kacharis of Cachar plains. Another origin of the name is that Veraka finds it's mention on the Harikela Coins. Which is identifiable to 'Barak' valley. Barak valley excluding Karimganj was once part of the Kachari kingdom. Some have suggested the word "Kachar" in Bengali language means a stretch of land at the foot of a mountain and Cachar might have been the name given by Bengalis of Sylhet to the land surrounded by mountains from all the sides. Others have pointed out that the name "Kachari" is widely prevalent in the Brahmaputra Valley and that the Dimasa people were known as "Kachari" even before they came to rule the Cachar plains, suggesting that it was the Dimasa people that gave the name Cachar to the plains.
