The Ahom kingdom was established in 1228 when
Sukaphaa, a Tai prince, entered the
Brahmaputra valley having crossed the rugged
Patkai mountain range from
Möng Mao. Sukaphaa probably started his journey from his homeland with a small number, but he was supported and joined by other Tai chiefs and common followers along the way and entered Assam with approximately 9,000 persons. His destiny was
Upper Assam, earlier the domain of the
Kamarupa kingdom but which had since lapsed into deteriorating conditions, and his intention was not to conquer and raid but to permanently settle in fallow land and practice agriculture The Ahoms were primarily responsible for converting the undulating alluvial forest and marshy plains in upper Assam to flat rice fields able to hold plain water for rice cultivation via a network of embankments. The Tai
Shans had with them the basic political structures for state-building (Mung), surplus producing technologies such as sedentary wet-rice cultivation and hydrology, a patriarchal social organisation based on clans (), and a
literary form of
their language. Whereas the earlier state formations (
Kamarupa) borrowed political structures from
North India that led to Indo-Aryan domination, the Ahom state formation provided an alternate model built on
Southeast Asian political structures, and which provided the space for the development of a distinct political, social and cultural identity. Though Brahminical myth-making was a common feature that all ancient and medieval kingdoms—such as
Chutia and
Kachari kingdoms—in Assam utilised for legitimacy to various degrees, the Ahoms were able to use their alternate Lengdon-based legitimacy to establish their rule and effectively negotiate with the indigenous people. Nevertheless the later
Tungkhungia kings veered towards
Saktism and the persecution of the
shudra Mahantas and their laity that began during the reign of
Siva Singha led to the
Moamoria rebellion and ultimately to the eclipse of the kingdom.
Mong Dun Shun Kham (1228–1401) Sukaphaa (1228–1268) spent a couple of decades moving from
place to place establishing colonies and finally settled down in
Charaideo in 1253. He established the offices of the Dangarias— the
Burhagohain (
Chao-Phrungmung) and the
Borgohain (
Chao-Thaonmung). In the 1280s, these two offices were given independent regions of control; partly hereditary and partly elected, the king and the two counsellors held each other in check and balance. Sukaphaa had instructed that events during his rule be chronicled, a practice sustained by his successors; and there emerged the institution of
Buranji writing, a practice of historiography rare in India. In the late medieval era, the Ahom kingdom was known to be a
kaghazi raj (a kingdom with records) just as the
Mughal Empire was. At the time of their advent, the Ahoms came with advanced technologies of rice cultivation, and it was their belief that they were divinely ordained to turn fallow land to agriculture and also to absorb stateless and shifting agriculturists to their own ways. The shifting people were called
kha and many such
kha people were ceremonially adopted into different Ahom clans, a process called
Ahomisation. Sukaphaa befriended those among the Morans and Barahi who were amenable to join him and put to the sword those who opposed him, and in due course, many others were incorporated into Ahom clans. The Ahoms were acutely aware of their smaller numbers, and adroitly avoided confrontations with larger groups. The additions via Ahomisation enhanced the Ahom numbers significantly. This process of Ahomisation was particularly significant till the 16th century when under
Suhungmung, the kingdom made large territorial expansions at the cost of the
Chutiya and the
Kachari kingdoms. At this initial stage the kingdom was still not fully sovereign. Sukaphaa sent his word of allegiance and tributes to
Möng Mao, a practice that was continued by some of his successors till about the early 14th century when the power of Möng Mao faded to be replaced the power of
Möng Kawng, at which point the Ahoms stopped the tributes. The Ahoms began to call their domain
Mong Dun Sun Kham ("a country of golden gardens"). Though Sukaphaa had avoided the Namdang region mindful of the numerically small Ahom contingent, his son Suteuphaa made the Kacharis withdraw on their own via a stratagem and the Ahoms expanded into it; but no further expansions of the Ahom domain occurred for the next two hundred years. The Ahom kingdom, for most of its history, had been closed and population movement closely monitored—nevertheless, there were two significant contacts. One was a friendly encounter with
Chutia kingdom that turned into a conflict, and the other was a marriage alliance with the
Kamata kingdom. At the end of the 14th century, the nascent Ahom polity faced crises of succession, two regicides, and three quick interregnum periods when the kingdom was without a king.
Assam (1401–1510) Sudangphaa Bamuni Konwar (), born and raised in a Brahmin household in
Habung, was identified as a descendant of a past king and installed on the throne by the
Burhagohain and
Borgohain to end the period of crisis. He established Brahmin officers, advisors and communities near the capital and the Brahmin influence, though negligible, was felt for the first time. A number of rebellions erupted purportedly against this influence but Sudangphaa was able to suppress them and solidify his rule. One of the rebels invited a military expedition from Mong Kwang (called Nara in the Buranjis, the successor state of Mong Mao to which the early Ahom kings used to send tribute) resulting in a clash in 1401—but Sudangphaa defeated the expedition and concluded the conflict with a treaty that fixed the boundary between the two polities at
Patkai. This event was significant since it moved the Ahom polity from implicit subordination to explicit sovereignty, and this was accompanied by the transition of the name of the polity from
Mong-Dun-Sun-Kham to "Assam", Sudangphaa established a new capital at Charagua, broke the clan allegiances that held the Ahom polity together earlier replacing it with political authority of the king, and introduced the tradition of the
singarigharutha ceremony, the state coronation of the Ahom kings that symbolised royal Ahom sovereignty, authority and legitimacy. Sudangphaa settled Habung brahmins close his capital, settled the sons of his adopted Brahmin family in frontier areas, dismantled the tribal allegiances that held the polity together earlier and brought the Ahom kingdom very close to a full-fledged state. The next hundred years saw the kingdom mostly suppressing rebellious Naga groups, but a conflict with the
Dimasa kingdom in 1490 saw the Ahoms, not strong enough to take them on frontally, suing for peace. The Ahom royalty continuously improved their relationship with the Brahmans which enabled them to gain goodwill with the Indo-Aryanized tribal groups and consolidate power.
Full state and expansion (1510–1609) The Ahom kingdom transitioned into a full state rather dramatically in a short period during the reign of
Suhungmung Dihingia Raja (). It began first with a consolidation of the militia in 1510, followed by an expansion into the region of Panbari at Habung (a Chutia dependency) in 1512 probably with the help of the descendants of the Habungia Brahmans settled during Sudangpha's time. A clash with the Hinduized
Chutia kingdom began in 1513, followed by its annexation in 1523 and the kingdom's nobility, commanders, professional classes, warriors and technologies were absorbed into the Ahom kingdom. In 1527, the
Baro-Bhuyans ruling in central Assam region of Rowta-Temoni were relocated to the north-bank of Upper-Assam and absorbed into the lower echelons of the growing state as scribes and warriors. It was this formation of the Ahom kingdom that met the aggression from Bengal under Turbak in 1532 and it was able to eliminate the aggressive leadership (with significant loss to itself) and pursue the retreating invaders to the
Karatoya river. In 1536, after the series of contacts with the
Kachari kingdom, the Ahom rule extended up to the
Kolong River in Nagaon; and by the end of Suhungmung's reign, the size of the kingdom had effectively doubled. These expansions created significant changes in the kingdom—the Assamese-speaking Hinduized subjects outnumbered the Ahoms themselves; and the absorption of the Chutia kingdom meant a wide range of artisan skills became available to it increasing the scope for division of labour. To provide legitimacy to the rule of the Ahom kings among the new subjects Suhungmung assumed the title
Swarganarayana (
Swargadeo), though nothing like the
Rajputisation process occurred with the Ahoms. The nature of the kings institutional relationship to the ministers changed with the creation of a new position, the
Borpatrogohain, named after a Chutia office; and the creation of the offices of
Sadiyakhowa Gohain (frontier region acquired from the Chutia kingdom) and the
Marangikhowa Gohain (territories acquired from the Kachari kingdom), The traditional nobles (
Chao) now aligned with the Brahmin literati and an expanded ruling class developed. And when the Ahoms under Ton Kham
Borgohain pursued the invaders and reached the
Karatoya river they began to see themselves as the rightful heir of the erstwhile
Kamarupa kingdom.
Maturing state (1609–1682) The Ahom kingdom became more broad-based and took many features of its mature form under
Pratap Singha (), primarily to meet the sustained attacks from the Mughals. The
Paik system was reorganized in 1609 under the professional
khel system, replacing the kinship-based system; and paiks could be permanently alienated to non-royal institutions via royal grants. Under the same king, the offices of the
Borphukan (viceroy of territories acquired from the Koches and the Mughals), and the
Borbarua (the "secretary" of the royal government) were established to increase the number of
Patra Mantris to five, along with other smaller offices. the Ahom kings adopting a Hindu name in addition to their Ahom names, and patronising Hindu establishments began with Pratap Singha, though formal initiation of the Ahom kings into Hinduism did not occur till 1648. The Assamese language entered the Ahoms court for the first time and briefly coexisted and eventually replaced the Ahom language. No more major restructuring of the state structure was attempted until the end of the kingdom.
Koch relations After the division of the Koch kingdom between two branches of the Koch dynasty in 1581, the Ahoms allied with their immediate western neighbor, the
Koch Hajo branch, from 1603 to prop them as a buffer against the Mughals who had extended their rule to
Bengal by 1576. The collapse of the Koch Hajo power in 1614 resulted in the Mughals coming to power up to the Barnadi River. The Mughals attempted further ingress to the east in 1616 with the
Battle of Samdhara which marked the beginning of the
Ahom–Mughal conflicts which lasted the till 1682 in the
Battle of Itakhuli, when the Ahoms were able to push the Mughals back to the west of the
Manas River permanently.
Mughal relations In 1657, owing to the 'War of succession' among the sons of
Shah Jahan. Ahom king
Jayadhwaj Singha extended his authority, occupied
Kamrup, preventing the other rebellious Koch king Pran Narayan from securing his footing. He speedily extended his authority over whole of western Assam. He brought under his domain the whole Brahmaputra Valley, from Sadiya in the east and
Sherpur on the south. Thus, the Ahom state attained the greatest territorial zenith. In 1662,
Aurangzeb to bring the lost tracts and to punish the rebels elements in that quarter, launched an invasion under his chief lieutenant
Mir Jumla II, in this invasion the Ahoms could not resist up well, and the Mughals occupied the capital, Garhgaon. Unable to keep it, and in at the end of the
Battle of Saraighat, the Ahoms not only fended off a major Mughal invasion but extended their boundaries west, up to the
Manas River. The western border was fixed at
Manas river after the
Battle of Itakhuli, which remained the same till the annexation by the British. Following the
Battle of Saraighat, the kingdom fell straight under ten years of political disorder. During this period the nobles exercised immense power, and seven kings were put on the throne and deposed. In the meantime,
Kamrup went back in the hands of Mughals for a few years.
Tungkhungia regime (1682–1826) Gadadhar Singha () established the 'Tungkhungia rule' in Assam, which continued to remain in power till the end of the kingdom. In 1682, the Mughals were defeated in the
Battle of Itakhul, and Manas river was fixed as the western boundary. Gadadhar Singha came in conflict with the Vaisnava
Satras who began commencing immense power and influence over the state and people, and started a wide–spread persecution of the Vaisnavites. riding litter The rule of
Tungkhungia Ahom kings was marked by achievements in the Arts and engineering constructions, the Tungkhungia regime witnessed a relative time of peace and stability till the
Moamoria rebellion, also festering internal conflicts that tore the kingdom asunder. According to Guha (1986) Ahom Assam continued to flourish till 1770. The Tungkhungia regime witnessed a relative time of peace till first half of the 18th century, where the population increased, trade expanded, Coinage and monetization made headway. New arts and crafts, new crops and even new style of dress were introduced.
Rudra Singha alias Sukhrungphaa (), under whom the Kingdom attained its zenith. He subdued the kingdoms of
Dimasa and
Jaintia. He had made extensive preparations to extend the boundary west–towards, attempted to make a confederacy of
Hindu kings of eastern India against
Mughals. But he died right before he could execute his plans in 1714. Rudra Singha had re–instated the Vaisnava Satras, he himself had taken initiation of the Auniati Gosain (
the most influential Brahmana Sattradhikar) but later in his life he got inclined towards
Shaktism, considering it to be more suitable for a monarch, he invited a famous Sakta Brahmana from Bengal–Krishnaram Bhattacharya alias Pravatiya Gosain. From his death bed he expressed his will that, all his five sons to be kings in an executive manner and advised them to take initiation of Parvatiya Gosain riding elephant with attendants
Siva Singha alias Sutanphaa (), he dropped his father's plan to invade Benagal. He took the initiation of Parvatiya Gosain and established him 'Nilachal mountain' with extensive land grants and paiks. Siva Singha was very much under the influence of Brahmanas and astrologers, 1722 it was predicted by the astrologers that his reign would soon come to a end owing to the evil influence of
Chatra–bhanga–yoga. Therefore, he transferred the royal umbrella and throne to his wife
Phuleshwari who was given the title of 'Bar–Raja' on the advice of Pravatiya Gosain. Phuleswari melded too much with the religious affairs, she had caused the insult of the Shudra–Mahantas.
Pramatta Singha alias Sunenphaa (), nothing of importance is recorded during his reign. He had erected the
Rang Ghar with masonry and built the Sukreswar and
Rudreswar temples in North–Guwahati. During his reign,
Kirti Chandra Borbarua gained much of his political influence. In 1744, he received an ambassador from the king of
Twipra. He died in 1751.
Rajeswar Singha alias Supremphaa (), he was put on the throne by
Kirti Chandra Borbarua by setting aside the claims of seniority of his elder brother
Barjana Gohain. Rajeswar Singha had erected the most number of temples among the Ahom Kings, he was an orthodox Hindu and took initiation of Nati–Gosian (a relative of Pravatiya Gosain). In 1765, he sent
an expedition to Manipur whose king
Jay Singha made an appeal to the Ahom king to recover his country from the
Burmese occupation. The first expeditionary force had to be routed off, which was sent through 'Naga Hills', in 1767 another force was despatched through the old
Raha route. The second expedition was successful and achieved its objective in recovering Manipur.
Kirti Chandra Borbarua who was the most influential noble in the Ahom court, had caused the burning of
Buranjis. Rajeswar Singha's reign marked the end of Ahom supremacy and glory, the signs were decay was already visible during his reign. He was succeeded by his younger brother
Lakshmi Singha alias Sunyeophaa ().
Downfall The Ahom kingdom by the mid-18th century was indeed an over-burdened hierarchical structure, supported by a weak institutional base and meagre economic surplus. The
Paik system which in the 17th century had helped the kingdom to repulse the repeated Mughal invasions, had become extremely outdated. The later phase of the rule was also marked by increasing social conflicts, leading to the
Moamoria rebellion were able to capture and maintain power at the capital Rangpur for some years but were finally removed with the help of the British under Captain Welsh. The following repression led to a large depopulation due to emigration as well as execution, but the conflicts were never resolved. A much-weakened kingdom fell to repeated Burmese attacks and finally after the
Treaty of Yandabo in 1826, the control of the kingdom passed into British hands. ==Ahom economic system==
