Assam ({{Indic Transl|as|asama|ɔ'xɔm|As-অসম-2.oga}} {{respell|ə|SoM|,_|a|SAM}}) is a state in northeastern India, south of the eastern Himalayas along the Brahmaputra and Barak River valleys. Assam covers an area of {{convert|78438|km2|mi2|abbr=on}}. It is the second largest state in northeastern India by area and the largest in terms of population, with more than 31 million inhabitants. The state is bordered by Bhutan and Arunachal Pradesh to the north; Nagaland and Manipur to the east; Meghalaya, Tripura, Mizoram and Bangladesh to the south; and West Bengal to the west via the Siliguri Corridor, a {{convert|22|km|mi|adj=mid|-wide}} strip of land that connects the state to the rest of India. Assamese and Bodo are two of the official languages for the entire state and Meitei (Manipuri) is recognised as an additional official language in three districts of Barak Valley and Hojai district.{{Cite news |last=Purkayastha |first=Biswa Kalyan |date=24 February 2024|title=Assam recognises Manipuri as associate official language in four districts|url=https://www.hindustantimes.com/india-news/assam-recognises-manipuri-as-associate-official-language-in-four-districts-101708770769105.html |work=Hindustan Times |access-date=17 May 2024}} in Hojai district and for the Barak valley region, alongside Bengali, which is also an official language in the Barak Valley.
The state has 35 districts with 5 divisions. Guwahati (containing the state capital Dispur) is the largest city in northeastern India. Assam is known for Assam tea and Assam silk. The state was the first site for oil drilling in Asia.{{cite web |url=https://www.financialexpress.com/opinion/here-is-indias-oil-story/1153719/ |title=Here is India's oil story |date=3 May 2018 |website=The Financial Express |access-date=21 July 2019 |archive-date=21 July 2019 |archive-url=https://web.archive.org/web/20190721050940/https://www.financialexpress.com/opinion/here-is-indias-oil-story/1153719/ |url-status=live }} Assam is home to the one-horned Indian rhinoceros, along with the wild water buffalo, pygmy hog, tiger and various species of Asiatic birds, and provides one of the last wild habitats for the Asian elephant. The Assamese economy is aided by wildlife tourism to Kaziranga National Park and Manas National Park, which are World Heritage Sites. Dibru-Saikhowa National Park is famed for its feral horses.{{Cite web |title=Dibru Saikhowa national park, Famous for wild horses, Tinsukia, Assam |url=http://www.assaminfo.com/tourist-places/5/dibru-saikhowa-national-park.htm |access-date=29 March 2025 |website=www.assaminfo.com}} Sal tree forests are found in the state which, as a result of abundant rainfall, look green all year round. Assam receives more rainfall than most parts of India; this rain feeds the Brahmaputra River, whose tributaries and oxbow lakes provide the region with a distinctive hydro-geomorphic environment.
Etymology
{{main|Etymology of Assam}}
The first dated mention of the region comes from Periplus of the Erythraean Sea (1st century) and Ptolemy's Geographia (2nd century), which calls the region Kirrhadia, apparently after the Kirata population.Besatia in the Schoff translation and also sometimes used by Ptolemy, they are a people similar to Kirradai and they lived in the region between "Assam and Sichuan" {{harv|Casson|1989|pp=241–243}}"The Periplus of the Erythraen Sea (last quarter of the first century A.D) and Ptolemy's Geography (middle of the second century A.D) appear to call the land including Assam Kirrhadia after its Kirata population." {{harvcol|Sircar|1990|pp=60–61}} In the classical period and up to the 12th century, the region east of the Karatoya river, largely congruent to present-day Assam, was called Kamarupa, and alternatively, Pragjyotisha."Prior to the thirteenth century the present region was called Kāmarūpa or, alternatively, Prāgjyotiṣapur", Lahiri, Nayanjot., Pre-Ahom Assam (Delhi 1991) p. 14 Though a western portion of Assam as a region continued to be called Kamrup, the Ahom kingdom that emerged in the east, and which came to dominate the entire Brahmaputra valley, was called Assam (e.g. Mughals used Asham); and the British province too was called Assam. Though the precise etymology of Assam is not clear, the name Assam is associated with the Ahom people, originally called Shyam (Shan)."Ahoms also gave Assam and its language their name (Ahom and the modern ɒχɒm 'Assam' come from an attested earlier form asam, acam, probably from a Burmese corruption of the word Shan/Shyam, cf. Siam: Kakati 1962; 1-4)." {{harv|Masica|1993|p=50}}

According to a late text, Kalika Purana (c. 9th–10th century CE), the earliest ruler of Assam was Mahiranga Danav of the Danava dynasty, which was removed by Naraka of Mithila and established the Bhauma dynasty. The last of these rulers, also Naraka, was slain by Krishna. Naraka's son Bhagadatta became the king, who (it is mentioned in the Mahabharata) fought for the Kauravas in the battle of Kurukshetra with an army of kiratas, chinas and dwellers of the eastern coast. At the same time towards the east in central Assam, Asura kingdom was ruled by another line of kings.India History Association.

Davaka was later absorbed by Kamarupa, which grew into a large kingdom that spanned from Karatoya river to near present Sadiya and covered the entire Brahmaputra valley, North Bengal, parts of Bangladesh and, at times Purnea and parts of West Bengal.The eastern border of Kamarupa is given by the temple of the goddess Tamreshvari (Pūrvāte Kāmarūpasya devī Dikkaravasini in Kalika Purana) near present-day Sadiya. "...the temple of the goddess Tameshwari (Dikkaravasini) is now located at modern Sadiya about 100 miles to the northeast of Sibsagar" {{harv|Sircar|1990|pp=63–68}}. The kingdom was ruled by three dynasties who traced their lineage from a mleccha or Kirata Naraka; the Varmanas (c. 350–650 CE), the Mlechchha dynasty (c.655–900 CE) and the Kamarupa-Palas (c. 900–1100 CE), from their capitals in present-day Guwahati (Pragjyotishpura), Tezpur (Haruppeswara) and North Gauhati (Durjaya) respectively. All three dynasties claimed descent from Narakasura. In the reign of the Varman king, Bhaskaravarman (c. 600–650 CE), the Chinese traveller Xuanzang visited the region and recorded his travels. Later, after weakening and disintegration (after the Kamarupa-Palas), the Kamarupa tradition was extended to c. 1255 CE by the Lunar I (c. 1120–1185 CE) and Lunar II (c. 1155–1255 CE) dynasties.

The Medieval Assam history may have started with the advent of Ahoms in the early part of the 13th century and covers their entire rule of 600 years till 1826. The medieval history of Assam is especially known for its conflict with Muslim powers under Turko-Afghan and Mughals, finally resulting in Assamese victory, however, this military glory was shattered in the early 19th century when it failed to resist the Burmese invasions, which led to its annexation.{{harvcol|Baruah|1986|p=36}}
=Chutia kingdom=
Chutia, a Bodo-Kachari group by origin, held the regions on both the banks of Brahmaputra with its domain in the area eastwards from Vishwanath (north bank) and Buridihing (south bank), in Upper Assam and in the state of Arunachal Pradesh. It was annexed by the Ahoms in the year 1524. The rivalry between the Chutias and Ahoms for the supremacy of eastern Assam led to a series of conflicts between them from the early 16th century.
=Kachari kingdom=
{{Main|Kachari kingdom}}
The Dimasa, a Bodo-Kachari dynasty that ruled from the 13th century until 1854, controlled territories stretching from the Dikhow River to central and southern Assam, with their capital at Dimapur. By the early 17th century, with the expansion of the Ahom kingdom, the Chutia regions were annexed, and by around 1536, the Kacharis were confined to the areas of Cachar and North Cachar. At this point, they became more of an ally to the Ahoms than a rival force.

{{Main|Sukaphaa}}
The Ahoms, a Tai group, ruled Upper Assam for almost 600 years.Banikanta Kakati, Assamese:Its formation and development In the year 1228 the Tai-Ahoms came to the Brahmaputra Valley under the leadership of Sukapha along with 9,000 men from Mong Mao, a Tai state, situated in South-Western Yunnan of China, and established his kingdom in Upper Assam. In 1253, he founded the capital city in a hillock and named it Charaideo. At the time of his advent, the area was inhabited by Morans and Borahis, to the north, to the north-east was the Chutia kingdom and to the south was the Kachari kingdom and to the west on the plains were the Baro-Bhuyans.
For more than two and a half centuries, Sukapha and his descendants, while primarily focused on administering the kingdom, upheld their dominance in the valley through their military prowess.{{Harvcol|Baruah|1986|pp=220–224}}

The reign of Suhungmung marked the first massive expansion of Ahom kingdom. Besides sending a punitive expeditions against the Nagas, they fought numerous battles with the Bhuyans, Chutias, Kacharis, Turko-Afghans, and the Naras. In 1522–23 the Chutia kingdom was annexed and the captured tract was placed under the administration of Sadiya-Khowa-Gohain. After securing the eastern tract, Suhungmung than expanded his kingdom westwards through conquest and extended it till Marangi to the west of the Dhansiri river. When the Kacharis tried to regain the lost territory they were defeated and their capital Dimapur was sacked. Over the remaining part of the Kachari kingdom, a new king Detsung was placed as a tributary, but Detsung proved disloyal and revolted against the Ahoms. He was subsequently executed. A new dependent king was set up on the Kachari throne with the name of Nirbhaynarayan. Since then the Kachari kings were regarded as 'thapita sanchita' meaning - established and maintained by the Ahom rulers.
Suhungmung's reign also witnessed the first Muslim-invasions of the kingdom. After a series of battle, the invaders were roundly defeated and were chased up to Karatoya River. The Sultan of Bengal, terrified by the approaching army of Suhungmung, made peace by offering his two daughters and five paraganas, along with other articles as dowry to the king. The rising Koch king Biswa Singha also offered his submission, and the Ahom general Ton-Kham granted him all the territories that were received as dowry from the Sultan of Bengal on the condition of annual tribute.{{Harvcol|Baruah|1986|pp=224–234}}
The successors of Suhungmung, Suklenmung and Sukhaamphaa, sent many expeditions against the Bhuyans and Nagas. But were significant with the wars with the Koch. During the reign of Sukhaamphaa, the Ahoms lost to a Koch army led by Chilarai and the Ahoms had to accept Koch supremacy and had to give up the tracts of north of Brahmaputra. However, the lost tract was soon recovered with further military expeditions.{{Harvcol|Gogoi|2017|pp=1–17}}

Soon after the death of Nara Narayan his kingdom, got divided between the sons of Nara Narayan and Chilarai as Koch Hajo and Koch Bihar. In 1609, Laxmi Narayan king of Cooch Behar accepted the vassalage of Mughals, and the Koch Hajo king Raghudev and later his son Parikshit sought assistance from Ahoms. In 1612, the Mughals attacked Koch Hajo and his territory up to Barnadi River were annexed in the Mughal domain. This brought the Mughals with direct contact with Ahoms. Meanwhile, Parikshit was trying to renew his friendship with Ahoms, but got captured, and died on his way to his kingdom. Later Balinarayan, a brother of Parikshit who had taken refugee under the Ahoms was made the king of Darrang in 1615 by the Ahom king Pratap Singha. From 1616, onwards many battles were fought the Mughal without any tangible result, with the first Battle of Samdhara till after the last battle where the treaty was concluded in 1639 which fixed the Asurar ali on the south bank and the Barnadi on the north bank of the Brahmaputra as the boundary between the two.
Pratap Singha had also enacted the Paik system and created a number of army and civil administration posts such as the Borbarua and Borphukan.
Jayadhwaj Singha taking the advantage of War of succession between the sons of Shah Jahan, occupied the imperial territories up to Dhaka. Aurangzeb after becoming the emperor, appointed Mir Jumla II, to recover the lost territory. After fail negotiations. In November 1661, Mir Jumla proceeded with a huge army and fleet to invade Ahom kingdom. Here the Ahoms, lost at several places, and then captured the Ahom capital Garhgaon. During the rainy season Mir Jumla and his army suffered immeasurable hardship due to the climatic condition of the valley in addition the guerrilla fighting resorted against the invaders. And at last no noticeable gain, negotiation started and in January 1663, Treaty of Ghilajharighat was concluded. According to the treaty, the Ahoms had to acknowledging Mughal supremacy, ceded the territory west of the Bharali on the north bank and the Kalang on the south bank along with a huge amount of war indemnity and handing over the sons of the Gohains as hostage and two Ahom princesses to the Mughal harem.File:Garh Garhchuck.jpg a 17th-century mud fort ruins]]Soon after the departure of Mir Jumla, Jayadhwaj Singha died and the new king Chakradhwaj Singha began preparations to overthrow Mughal supremacy and to recover the lost territory. After numerous battles, finally after the Battle of Saraighat the Mughals were forced to retreat.
The period after 1671 was very unstable due to the rivalry among the nobles, who wanted to arrest their own political power and influence by placing their own choice of prince in the throne. In 1679, Laluksola Borphukan, in hopes of becoming king with the help of Mughals, surrendered Guwahati without any battle. But after the accession of Gadadhar Singha, fought the final Battle of Itakhuli where the Mughals were badly defeated. And the since then the border was fixed at Manah on the north bank and the Nagarbera hill on the south bank of the Brahmaputra till its annexation by the East India Company in 1826."In the Battle of Itakhuli in September 1682, the Ahom forces chased the defeated Mughals nearly one hundred kilometers back to the Manas river.

Rudra Singha succeeded Gadadhar Singha, his reign is notable because of his military achievements and his socio-culture contributions. He had both subjugated the Kachari and Jaintia kingdoms, and had captured their kings and forced to accept Ahom suzerainty and agreed them to pay annual tribute. Other than that, several expeditions were sent against the Miris, the Daflas, the Naga Mishmis and the Nagas of Namsung, Dayang and the Rengma Nagas during late 17th century and early 18th century. Rudra Singha had made extensive preparations for his invasion of Bengal but remained unfulfilled due to his sudden death in 1714.
After Rudra Singha, the Ahoms achieved no notable military achievement. During this period from, Siva Singha to Rajeswar Singha, the kingdom witnessed peace and prosperity and was significant for constructive activities and other development. In the field of religion also, Ekasarana Dharma spread all over the kingdom and started to influence all aspects of people's life. The religious heads of Vaisnavite monastery exalted great influence with royal patronage and established numerous Satras and most of the people became their disciples. So got the Ahom court greatly came under the influence of Sakta Brahman priests and astrologers. The religious policies concluded by Phuleshwari and the persecutions of unfavored Satras, embroiled the situation more along with the pressure of Paik system in the 18th century.{{Harvcol|Gogoi|2017|pp=20–26}}
This finally resulted in the Moamoria rebellion (1769–1805), which greatly weakened the Ahom kingdom where the country was greatly depopulated and unorganised. The political rivalry between the nobles made a pathway for a devastating set of invasions by the Burmese, weakening it more and finally leading to its annexation.

Problems with the imported Han Chinese labourers from China and hostility from native Assamese resulted in the migration of forced labourers from central and eastern parts of India. After initial trial and error with planting the Chinese and the Assamese-Chinese hybrid varieties, the planters later accepted the local Camellia assamica as the most suitable variety for Assam. By the 1850s, the industry started seeing some profits. The industry saw initial growth, when in 1861, investors were allowed to own land in Assam and it saw substantial progress with the invention of new technologies and machinery for preparing processed tea during the 1870s.
Despite the commercial success, tea labourers continued to be exploited, working and living under poor conditions. Fearful of greater government interference, the tea growers formed the Indian Tea Association in 1888 to lobby to retain the status quo. The organisation was successful in this, but even after India's independence, conditions of the labourers have improved very little.{{Citation |last1=MacFarlane |first1=Alan |last2=MacFarlane |first2=Iris |title=Green Gold, The Empire of Tea, Ch. 6–11 |publisher=Random House, London |year=2003}}
In the later part of the 18th century, religious tensions and atrocities by the nobles led to the Moamoria rebellion (1769–1805), resulting in tremendous casualties of lives and property. The rebellion was suppressed but the kingdom was severely weakened by the civil war. Political rivalry between Prime Minister Purnananda Burhagohain and Badan Chandra Borphukan, the Ahom Viceroy of Western Assam, led to an invitation to the Burmese by the latter,Gait E.A.

The arrangement lasted until 1838 and thereafter the British gradually annexed the entire region. Thereafter the court language and medium of instruction in educational institutions of Assam was made Bengali, instead of Assamese. Starting from 1836 until 1873, this imposition of a foreign tongue created greater unemployment among the People of Assam and Assamese literature naturally suffered in its growth.{{Cite book |title=North-East India, Problem Prospect and Politics |last=Barpujari |first=H.K. |publisher=Spectrum Publishers. |year=1998 |location=Guwahati |page=41}}{{Cite book |title=Social History of Assam |last=Bose |first=M.L. |publisher=Ashok Kumar Mittal Concept Publishing Company |year=1989 |location=New Delhi |page=91}}

Initially, Assam was made a part of the Bengal Presidency, then in 1906 it was made a part of Eastern Bengal and Assam province, and in 1912 it was reconstituted into a chief commissioners' province. In 1913, a legislative council and, in 1937, the Assam Legislative Assembly, were formed in Shillong, the erstwhile capital of the region. The British tea planters imported labour from central India adding to the demographic canvas.
The Assam territory was first separated from Bengal in 1874 as the 'North-East Frontier' non-regulation province, also known as the Assam Chief-Commissionership. It was incorporated into the new province of Eastern Bengal and Assam in 1905 after the partition of Bengal (1905–1911) and re-established in 1912 as Assam Province.William Cooke Taylor, A Popular History of British India. p. 505
After a few initially unsuccessful attempts to gain independence for Assam during the 1850s, anti-colonial Assamese joined and actively supported the Indian National Congress against the British from the early 20th century, with Gopinath Bordoloi emerging as the preeminent nationalist leader in the Assam Congress.{{citation needed|date=June 2020}} Bordoloi's major political rival in this time was Sir Saidullah, who was representing the Muslim League, and had the backing of the influential Muslim cleric Maulana Bhasani.{{cite web |url=http://www.satp.org/satporgtp/publication/faultlines/volume13/Article2.htm |title=The Secessionist Insurgency and the Freedom of Minds |last1=Nath |first1=Sunil |year=2001 |website=www.satp.org |publisher=Institute for Conflict Management|access-date= 24 January 2014|archive-url= https://web.archive.org/web/20180417020155/http://www.satp.org/satporgtp/publication/faultlines/volume13/Article2.htm|archive-date= 17 April 2018|url-status=live }}

At the turn of the 20th century, British India consisted of eight provinces that were administered either by a governor or a lieutenant-governor. Assam Province was one among the major eight provinces of British India. The table below shows the major original provinces during British India covering the Assam Province under the Administrative Office of the Chief Commissioner.
With the partition of India in 1947, Assam became a constituent state of India. The Sylhet District of Assam (excluding the Karimganj subdivision) was given up to East Pakistan, which later became Bangladesh.
