# Barak Valley

The Barak Valley is the southernmost region and administrative division of the Indian state of Assam. It is named after the Barak river. The Barak valley consists of three administrative districts of Assam namely - 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.

## Etymology

The name "Barak" has 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.
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.

## Districts

Barak valley Division comprises three districts, namely Cachar, Karimganj, and Hailakandi.

## History

The Barak river today splits into the northern Surma and the southern Kushiara between the towns of Badarpur in the east and Karimganj in the west. Inscriptions suggest that in the 10th century the region around Surma and Kushiara formed frontier settlements called Srihatta and Khanda Kamarupa established by Kamarupa kings in the 7th century. Till 1787, when Brahmaputra changed its course to meet the Meghna a hundred miles farther south, the land between Netrokona in the west and Sylhet in the east was inundated for half of each year forming haors which made the higher plains of the upper Surma-Kushiara basin not as easily accessible from the west as it was from the Cachar plains in the east.
The three districts of the Barak Valley have their own historical origins; nevertheless the region has been defined not from a natural growth from social, historical or cultural lives of the vernacular groups present in these regions, but they are the products of empire building, especially under the East India Company (EIC) and the British Raj. The pre-colonial kingdoms were not cartographically defined; they were rather defined according to heartlands, and the defence of the margins were not important, and it was communities living in different places owing loyalties to different royal lineages that implied territories. The EIC interests led to drastically differently defined cartographic territories—it was in the interest of the two contending parties, the Tripura and the Kachari kingdoms, to define a boundary east to west across the Dalasuri flowing south to north and settle whether Hailakandi was control of the Tripuri or the Kachari polity; whereas the EIC was more interested in defining a north–south border along the Dalasuri so it could be defended.

### Pre-colonial formations
#### Cachar

In the 16th century, the Tripura kingdom was in control of the Cachar plains, when in 1562 the Koch general Chilarai annexed the Cachar region to the Koch kingdom and it came to be administered from Khaspur (or Kochpur) by his half-brother Kamalnarayan. After the death of the Koch ruler Nara Narayan, the region became independent and was ruled by the descendants of Kamalnarayan and his group, and they became known as the Dehans (after Dewan). Between 1745 and 1755, the last Koch ruler's daughter married the king of the Kachari kingdom, and the rule of Khaspur passed into the hands of the Kachari rulers who adopted the title Lord of Hedamba.
The Kachari kings at Khaspur appointed Brahmins as rajpandits and rajgurus and provided land grants to Muslims from Sylhet for cultivation. Some people from Manipur and the Ahom kingdom too moved to the Cachar plains following disturbances in those lands. In 1835, Pemberton reported that the population of the Cachar plains was around 50,000 dominated by the Dimasa people, followed by Muslim immigrants from Sylhet and their descendants; a third group was Bengali and Assamese immigrants and their descendants and Naga, Kuki and Manipuris forming the smallest groups.

#### Hailakandi

Hailakandi, claimed by both the Tripura and Kachari kingdoms, was a market town on the banks of the Dalasuri river which connected the resource-rich southern hills with the markets in the north along the Barak river. In 1821-22 when Thomas Fischer surveyed the area, he found that Hailakandi was controlled by the Kacharis, though it was surrounded by villages of the Kuki Tanghum community that owed allegiance to the Tripura kingdom. In this region a past Tripura king received a princess from Manipur. It was uncertain which of the three kingdoms the communities paid their tributes to and it effectively formed a boundary zone, a concept that differed significantly from the idea of clearly defined borders between kingdoms.

#### Karimganj

East India Company had pushed into the region east of Sylhet town slowly after it won the right to collect land revenue under the Treaty of Allahabad in 1765. Among these, Karimganj became a sub-division of the eventual colonial Sylhet district which became a part of Assam in 1874. Following a referendum in 1947 Sylhet was attached to East Pakistan during partition of India in the same year, except for four thanas of the erstwhile Karimganj subdivision that was attached to the Cachar district of Assam, India.
Sylhet is farther to the west of Karimganj, also on the Surma. No state control existed in the Sylhet region till the establishment of Sarkar Sylhet when the Mughals established a Faujdar at Sylhet in 1612. In 1303, Shah Jalal had established rule around Sylhet; and during Ibn Battuta's visit in 1346, the region was inhabited by Khasi, Garo, Hindus, Muslims, and others. The Mughals began the practice of settling cultivators in the region around Sylhet, which picked up significantly only after 1719 and lasted till the beginning of East India Company rule in 1765. The expansion of Mughal domains in Sylhet was part of an ancient process of Gangetic territorialism that displaced or assimilated extant populations consisting of Munda, Khasi and other peoples. The Mughal administration granted land in Sarkar Sylhet to talukdars, called Chaudhuri, in smaller land parcels called taluks, as opposed to larger zamindars in the rest of Bengal. Sylhet was itself a borderland when the EIC acquired the Mughal Sarkar Sylhet in 1765.

### Colonial boundaries

EIC acquired Sarkar Sylhet, primarily the frontier town, bounded by regions that were not in their control—Mughal holdouts moved freely in the lowlands controlled by the highland rulers out of Company reach; Khasi chiefs held most of the land north of the Surma; the land north and east of Sylhet town belonged to the Jaintia kingdom; and Tripura kingdom held most of the southern highlands and the adjoining lowlands. The EIC, an erstwhile mercantile company, got into the revenue-farming and judiciary business with the diwani grant of 1765 and developed a keen interest in monopolising traditional trade routes and expanding settled farming for revenue. This was achieved by marking boundaries—company officers served the EIC interests in generating more revenue and confronting Ava militarily, but they also served their own private commercial interests.
According to David R. Syiemlieh, up to 1837 A.D. the plains of Cachar Valley were sparsely populated and were dominated by the Dimasa Cachari, a Tibeto Burmese tribe, under the rule of the Kachari Raja, who have established his kingdom's capital at Khaspur, Cachar plains. He had a good number of Bengali advisers (mostly Brahmins) around him and gave grants of land to some of them, but the population resembled that of the North Cachar Hills of today as evident from various historical chronicles and sources. Bengali settlers from neighbouring East Bengal poured into the Cachar plains after the British annexation of the region in 1832 A.D., turning it into a Bengali-majority region. Once, Barak Valley from (1832–1874) A.D. was a part of the Bengal Presidency under the British Empire. The British Annexation of Cachar transformed the demographic patterns of the valley overnight. There was a sudden phenomenal growth in population, while the plains of Cachar had about 50 thousands inhabitants in all in 1837 A.D. that is five years after its annexation, which eventually indicates that there was a large-scale immigration. The population rose to more than five lakhs a few years later. The population of Muslims in the colonial era Barak Valley decreased in the late 19th century largely because the fertile lands were occupied by earlier settlers of the region and later they immigrated to the present Hojai of Assam which was also a part of Kachari Kingdom up to 1832 AD. A population 85,522 of diverse backgrounds including hill tribes, in the 1851 Census, Muslims and Hindus, 30,708 and 30,573, respectively, mostly Bengalis, constituted 70% of the total population of Cachar Valley, followed by 10,723 Manipuris, 6,320 Kukis, 5,645 Naga and 2,213 Cacharis. Karimganj district, which have become a part of Cachar Valley plains after 1947, was a part of Sylhet before the Partition of Bengal (1947). The region of Karimganj was under the rule of Pratapgarh Kingdom from 1489-1700s.

### Inclusion of Karimganj

In 1947, when a plebiscite was held in Sylhet of then Assam Province with majority voting for incorporation with Pakistan. The Sylhet district was divided into two; the easternmost subdivision of Sylhet which is known as Karimganj joined with India, and now is a district of Assam, whereas the rest of Sylhet joined East Bengal. Geographically the region is surrounded by hills from all three sides except its western plain boundary with Bangladesh. Nihar Ranjan Roy, author of Bangalir Itihash, claims that "South Assam / Northeastern Bengal or Barak Valley is the extension of the Greater Surma/Meghna Valley of Bengal in every aspect from culture to geography".
Assam's Surma Valley (now partly in Bangladesh) had Muslim-majority population. On the eve of partition, hectic activities intensified by the Muslim League as well Congress with the former having an edge. A referendum had been proposed for Sylhet District. Abdul Matlib Mazumdar along with Basanta Kumar Das (then Home Minister of Assam) travelled throughout the valley organising the Congress and addressing meetings educating the masses about the outcome of partition on the basis of religion. On 20 February 1947 Moulvi Mazumdar inaugurated a convention – Assam Nationalist Muslim's Convention at Silchar. Thereafter another big meeting was held at Silchar on 8 June 1947. Both the meetings, which were attended by a large section of Muslims paid dividend. He was also among the few who were instrumental in retaining the Barak Valley region of Assam, especially Karimganj with India. Mazumdar was the leader of the delegation that pleaded before the Radcliffe Commission that ensured that a part of Sylhet (now in Bangladesh) join with India despite being Muslim-majority (present Karimganj district). In return of that, Moulvibazar the only Hindu-majority district of Sylhet Division was given to East Pakistan during partition.

## Statehood demand

Most Bengali organisations of Barak Region have demanded a separate state for the people of Barak within the Bengali majority areas of Assam, particularly Bengali majority Barak valley, comprising the three districts Cachar, Hailakandi, Karimganj, as well as historical Dima Hasao of Undivided Cachar Valley and some parts of Hojai district to meet the criteria for creating a separate state for themselves by carving out from Assam's Assamese majority Brahmaputra valley post NRC. Silchar is the proposed capital of Barak state. Barak Valley is the most neglected part of Assam in terms of its infrastructure development, tourism sector, educational institutions, hospitals, IT industries, G.D.P, H.D.I etc. which is still lagging behind in comparison to the Assam's mainland Brahmaputra valley that has access to all of those facilities mentioned above. On 20 January 2023, Barak Democratic Front's Chief Convenor and former ACKHSA leader Pradip Dutta Roy said, "If Centre is planning to grant separate statehood to Kamtapur, then they should also fulfill the longstanding demand of separate Barak state by granting the region separate statehood". On 7 September 2023, Assam Chief Minister Himanta Biswa Sarma delivered a speech at a rally in Silchar and stated that "If the people of Barak Valley want separation, I will not oppose that demand. Rather the people of Barak Valley should reconsider an independent Barak state." The BDF subsequently conducted a press conference on 8 September 2023 and congratulated the Chief Minister for providing implicit support to the separation call. The southernmost region of Assam that is Barak Valley has an overwhelming Bengali majority population of about 80.8% as per 2011 census report. On 27 September 2023, members of Barak Democratic Front (BDF) held a press conference at the Kolkata Press Club shedding light on the long-standing grievances of Barak Valley residents while attempting to garner support for the creation of a new Purbachal state, separate from Assam. On 29 November 2023, the demand for separate Barak state have been raised before the office of Prime Minister and Home Minister and a memorandum was also submitted by the members of Barak Democratic Front in Parliament of India.
The indigenous Dimasa Cachari people of Northeast India have been demanding a separate state called Dimaraji or "Dimaland" for several decades. It would comprise the Dimasa-inhabited areas, namely North Cachar Hills, greater parts of Cachar district, Hailakandi district, significant parts of Hojai district and Karbi Anglong district in Assam together with part of Dimapur district in Nagaland.

## Festivals

Durga puja is one of the major festivals of Barak valley, as the region is home to a large population of Bengalis in Assam. Durga puja is celebrated with great fervour and enthusiasm in every part of the region be it rural or urban areas with great joy and happiness. Annually, on average 2,500 puja pandals have been organised by puja committees throughout the valley, with 300 durga puja pandals are being concentrated in Silchar alone. The festival marks the victory of good over evil.
Kali Puja is one of the most celebrated festivals in the valley after Durga Puja. Every year around 2000 Puja pandals are built in the region to mark the beginning of this festival and to seek the blessings of the goddess Kali for general happiness, health, wealth and peace through prayers
Busu Dima is an annual cultural festival celebrated by the Dimasa Kachari tribe of North Cachar Hills and Cachar of Barak valley. It is the biggest harvesting agricultural festival. It is celebrated after the completion of grain harvest in different villages of the valley and hills. The festival is usually organised in the month of January.
Baidima is a tradition festival of Indigenous Dimasa Cachari tribe of North Cachar Hills and Cachar. It is being celebrated in the month of January just after Busu Dima festival. The traditional dance continued for a week. On that day, along with dance they also sing songs. In haflong, locals organised cultural events, public meetings, rally and various programs related to this festival.
Charak puja (Pohela Boishakh) the Bengali new year, is one of the most important and major festivals of the valley celebrated by the ethnic Bengalis, irrespective of their religious affiliation and social status. This festival marks the beginning of Bengali new year and is being celebrated 15 April every year.

### Eid

Eid is also a major festival of the region as the Muslims constitute half of valley's population. Just like Durga puja, every year lakhs of Muslims celebrated eid with great joy and happiness throughout the valley specially in Muslim-majority Karimganj and Hailakandi district.

## Social issues
### Bengali Language Movement in Barak Valley

Over 80 per cent of Assam's Barak Valley are Bengali people and speak Bengali language. On 24 October, a bill was passed by Assam's late Chief Minister Mr. Bimala Prasad Chaliha in the Assam Legislative Assembly making Assamese as the only sole official language of the state. On 5 February 1961, the Cachar Gana Sangram Parishad was formed to protest against the imposition of Assamese in the Bengali-speaking Barak Valley. Rathindranath Sen was chief person of the organisation. People soon started protesting in Silchar, Karimganj and Hailakandi. On 24 April, the Parishad flagged off a fortnight-long Padayatra in the Barak Valley to raise awareness among the masses, which ended after 200 miles reaching to Silchar on 2 May. On 18 May, the Assam police arrested three prominent leaders of the movement, namely Nalinikanta Das, Rathindranath Sen and Bidhubhushan Chowdhury, the editor of weekly Yugashakti. On 19 May, the dawn to dusk hartal started. Picketing started in the sub-divisional towns of Silchar, Karimganj and Hailakandi. A Bedford truck carrying nine arrested activists from Katigorah was fired and the truck driver and the policemen escorting the arrested fled the spot. Soon after that the paramilitary forces, guarding the railway station, started beating the protesters with rifle butts and batons without any provocation from them. They fired 17 rounds into the crowd. Twelve persons received bullet wounds and were carried to hospitals. Nine of them died that day. Two more persons died later. One person, Krishna Kanta Biswas survived for another 24 hours with a bullet wound in chest. Ullaskar Dutta send nine bouquets for nine martyrs. On 20 May, the people of Silchar took out a procession with the bodies of the martyrs in protest of the killings. After the incident and more protests, the Assam government had to withdraw the circular and Bengali was ultimately given official status in the Barak region by Assam government. Soon after that a circular of Section 5 of Assam Language Act XVIII, 1961, was enacted to safeguards the use of Bengali language in the Cachar district. It says, "Without prejudice to the provisions contained in Section 3, the Bengali language shall be used for administrative and other official purposes up to and including district level."

### Language controversy

On 18 October 2021, a state government hoarding which was written in Assamese language has been found smeared with black ink in Barak valley's administrative capital Silchar's Petrol Pump area. It was found that two Bengali organisations namely: Barak Democratic Yuba Front and All Bengali Students Youth Organisation have been involved in that activity and have accused that the government of Assam has been trying to impose their Assamese language on us (referring to Bengali-majority Barak Valley) through Assamese hoarding as a starting and have said that "We strictly stands against it (i.e imposition)". The smearing of the government hoarding has led to condemnation from people and various regional organisations of the Brahmaputra Valley, where Assamese organisations such as All Assam Students Union and Asom Jatiyatabadi Yuba Chatra Parishad have severely reacted, deeply saddened and protested against it. In retaliation, several Bengali hoardings in Assamese-dominated Brahmaputra Valley have also meet the same fate. The political 'language wars' and strife between the ethnic Assamese and Bengalis have led to several 'martyrs' on both sides of the administrative divisions. On 19 May 1961, 11 Bengali Protestors at Silchar railway station were killed for protesting against forceful imposition of Assamese language in Barak Valley region. Similarly, during Assam Movement of (1979–1985) or popularly known as the Assam Agitation which aims at detaining and deporting Illegal Bangladeshi immigrants from the state saw as many as 855 Assamese people gave up their lives to protect the Linguistic, ethnic and cultural identity of Assam.

### Immigration of Bengali refugees in Cachar Valley

In 1947 during Partition of Bengal period, it has been found that from 15 August 1947 to April 1950, the Bengali Hindu refugees population in Cachar increased to 200,000 and but after Liaquat–Nehru Pact it came down to 93,177 in 1951. According to 1961 census, the number of East Bengali refugees living in Cachar alone is found to be 156,307 which is way higher than the previous census. No new Hindu immigration happened in the post 1971 period in Barak valley. Bengali Hindus who landed up in Barak valley from Bangladesh in the post 1971 census have moved out of the region before the 1991 census. The number of Hindu immigrants from Bangladesh in Barak Valley has varied estimates. According to the Assam government, 1.3–1.5 lakh such people residing in the Barak Valley are eligible for citizenship if the Citizenship Amendment Act of 2019 becomes a law. There were reverse im-migration vice-versa trends as well. The Muslim percentage of the Cachar Valley have decreased from 42.48% to 38.49% during (1941–1951) period. On the eve of Partition of Bengal and Sylhet Referendum, most of Bengali Muslim employees hailing from Barak Valley opted for Pakistan's Sylhet and migrated there as refugees. Similarly, Bengali Hindu employees hailing from Sylhet opted for Cachar Valley and majority of them settled in the Cachar plains thereafter. Also during partition, most of the Sylhet-origin Muslim businessmen living in Cachar and Karimganj have exchanged their business, houses and residences with Hindu businessmen of Sylhet migrating to Cachar and Karimganj.
In March 2020, Wasbir Hussain, the editor in chief of North East Live and member of clause 6 committee while defining who is an Assamese have stated that the original inhabitants of Barak valley are a part of greater Assamese society and he further said that illegal immigrants and migrants are of different bracket. Regarding Indigenousity, Those Bengali-speaking Hindus/Muslims of Barak Valley (comprising districts of Cachar, Hailakandi and Karimganj) who bears surnames like Choudhury, Mazumdar/Mazumder, Laskar/Lashkar, Barlaskar, Barobhuiya, Mazarbhuiya, Talukdar and Hazari and other regular titles mostly brought and given by Kachari kings are Native. The Barak Valley region is often described as a division filled with Bangladeshis. It lost its "Bangladeshi tag" after the final NRC draft results were published on 31 July 2018. Mr. Paul, a resident of Cachar district, said that the latest NRC draft had put an end to the controversy regarding the citizenship of the residents of the Valley. He further said: "It was often claimed that they are all or the majority of people of the valley are from Bangladesh. NRC draft results have shown that nearly 90% of Barak residents are Indian citizens. The Barak Valley had a population of about 37 lakh, as per last 2011 Census. NRC draft have dropped four lakh of the 37 lakh residents, majority of whom are Bengali people. As per NRC results, about 8% of the residents of Cachar, 11.82% of Karimganj and 14.2% of Hailakandi didn't feature their names on the latest final draft list. As a whole, about 11% residents of Barak could not make their name appears on the list. The Assam Indigenous People Protection Committee has protested the exclusion of indigenous people in the final NRC list, which was published on 31 August 2019 in Assam's Barak Valley region. According to the Committee, nearly 1.5 lakh people belong to the Dimasa, Koch Rajbongshi, Meiteis, Manipuri-Muslim (Pangals), Bishnupriya Manipuri, Cachari-speaking Muslim, tea tribes, Naga people (particularly Rongmei), Kuki, Khasi, Gorkha, Hmar, Das Pattni, Nath Jogi and Namasudra Bangali communities were left out of the final NRC list. The Committee further stated that, "All the Indigenous people of Barak Valley support the government stand of Implementing Clause 6 of the Assam Accord". One of the early attempts to define the native people of Assam is found in the 1951 Census of Assam. It's clearly stated that "An Indigenous person of Assam means a person belonging to the State of Assam and speaking the Assamese language or any tribal languages- (Dimasa, Rabha, Koch Rajbongshi, Bodo, Mishing, Karbi etc.) of Assam, or in the case of Cachar Valley, the language of the region (Bangla)".

### Barak-Mizoram dispute

Mizoram used to be a district of Assam as Lushai hills before being carved out as a separate union territory and later, becoming another separate state in 1987 by States Reorganisation Act, 1956. Because of the history, the district's borders did not really matter for local Mizos for a long time. Mizoram shares a border with the districts Cachar, Hailakandi and Karimganj which comes under Barak valley region of Assam.
Over time, the two states started having different perceptions about where the demarcation should be. While Mizoram wants it to be along an Inner Line Permit notified in 1875 to protect indigenous tribals from outside influence, which Mizos feel is part of their historical homeland, Barak valley region of Assam wants it to be demarcated according to district boundaries drawn up much later. Conflicting territorial claims have persisted for long between Assam's Barak and Mizoram, which share a 164.6 km inter-state border. There were several clashes between the local people of the Mizoram and Barak regarding land disputes in the border areas on regular basis. The root of the dispute is a 1,318 km$^2$ ( 509 square miles) area of hills and forests that Mizoram claims as its own. This is on the basis of an 1875 British law. But Assam insists this area is part of theirs as its "constitutional boundary". On 17 November 2022, Mizoram Home Minister have apologised for the clashes that have occurred in Barak-Mizoram border in which six police personnel and one civilian were killed in Lailapur.
