The Ahom (Pron: ) or Tai Ahom (; ) are an ethnic group primarily found in the Indian states of Assam and Arunachal Pradesh. They are the admixed descendants of Tai peoples who migrated into the Brahmaputra Valley and of indigenous populations incorporated into their society over the course of history, through a process called Ahomisation. Traditional accounts place the arrival of the Tai group led by Sukaphaa in 1228 and date the foundation of the Ahom kingdom to the same year. Recent scholarship has, however, questioned this chronology, arguing that the available Tai and Chinese sources may instead indicate that the Ahom polity was established in the 14th century. Over the following centuries, the kingdom expanded across much of the Brahmaputra Valley in present-day Assam and endured until the signing of the Treaty of Yandabo in 1826.
The modern Ahom people and their culture are a syncretism of Tai and local Tibeto-Burman speakers. A 2024 genome-wide study found substantial admixture of modern Ahoms with local Tibeto-Burman and other South Asian populations, and concluded that they had substantially lost the genetic ancestry associated with their ancestral Southeast Asian homeland. The mixture of immigrants and local peoples who underwent Ahomisation came to be known as "Ahom". Many local ethnic groups that came in contact with the Tai settlers, including the Borahis, were completely subsumed into the Ahom community. Members of other communities were accepted as Ahoms based on their allegiance to the Ahom Kingdom or the usefulness of their talents. A 2004 genetic study has found that in the "tribal" and "caste" continuum, the Ahom people occupy an ambiguous position in the middle,"The process of assimilation of some of the tribes in the caste hierarchy is probably reflected in the broad constellation of populations in the multidimensional plot (Fig. 3); on the one end it is the constellation of populations subscribing to the caste system, while the other end of the plot is the constellation of tribal groups. In between lie groups like the Rajbanshi, Chutiya, and Ahom, which were supposed to have undergone the process discussed above." along with the Koch-Rajbanshis and Chutias."The Chutia, Ahom, and Rajbanshis constitute a separate and compact cluster positioned in the center of MDS plot."
Even though the already admixed group"The Ahom kingdom's establishment, traditionally dated at 1228, was done by a group migrating from the southeast, large numbers of whom were male army members, who would have taken local non-Tai speaking wives." , Ahom, made up a relatively small portion of the kingdom's population; they maintained their Ahom language and practised their traditional religion until the 17th century, when the Ahom court as well as the commoners adopted the Assamese language.
Currently, they represent the largest Tai group in India. Ahom people are found mostly in Upper Assam division in the districts of Golaghat, Jorhat, Sivasagar, Charaideo, Dibrugarh, Tinsukia (south of Brahmaputra River); and in Lakhimpur, Sonitpur, Biswanath, and Dhemaji (north) as well as some areas of Nagaon in Guwahati.
Etymology The name Ahom is an exonym; the people referred to themselves as Tai. Banikanta Kakati notes that the Tai migrants who entered the Brahmaputra valley came to be called Asam, Āsām and Ācām by the indigenous population, and derives the modern Assamese ethnonym Ahom through the development Āsām → Asam → Aham → Ahom. Kakati further relates the element -sām to Sham/Shan or Syam, an old external designation for Tai peoples.
History
Origins The Tai speaking people came into prominence first in the Guangxi region, in China, from where they moved to mainland Southeast Asia in the middle of the 11th century after a long and fierce battle with the Northern Han Chinese. The Tai Ahoms are traced to either Mong Mao of South China (present-day Dehong, Yunnan of China)"At present [Mong Mao] is known as Ruili in Chinese maps... The Mong Mao area is still predominantly Tai, who are called Dai (in Pin Yin), and they, together with the Singhpho, or Jingpho, form a dominant group, hence the whole zone is named as Dehong Dai-Jingpho Autonomous Prefecture in Yunnan." or to the Hukawng Valley in Myanmar.
According to the traditional chronology, Sukaphaa, a Tai prince from Mong Mao, entered Assam in 1228 with a group of followers intending to establish a permanent settlement.“Sukapha and his band of Ahom migrants entered Upper Assam in 1228 with a view to permanently settling there.” They are traditionally believed to have brought techniques of wet-rice cultivation, a system of writing and record-keeping, and traditions of state formation. Recent scholarship has, however, questioned this chronology, proposing that the Ahom polity may instead have been founded in the mid-14th century. Linguistic research has likewise suggested that the Ahom script developed only between the late 14th century and the 16th century."Although tradition suggests that the Ahom brought their script with them when they crossed the Patkai Mountains into Assam in the 13th century from Mong Mao, located on the frontier of what is now Myanmar and China (Phukan 2006); it is unknown how old the script actually is. The oldest surviving Ahom text, the Snake Pillar inscription, only dates back to the time of King Siuw Hum Miung who reigned during 1497-1539 (Hosken and Morey 2012). However, the resemblance between the Ahom script and one of the extant Shan scripts known as lik hto ngouk, or “bean-sprout letters”, points to a common origin (Cushing 1888; Ferlus 1988; Diller 1992; Wichasin 1986). A recent paper by Daniels (2012) refers to a manuscript published in Yang, Bartholemew and Wang (2000). This has been identified as a Chinese manuscript dated 1407 that includes Tai language very similar in form and structure to the Tai Ahom script, suggesting that a script like Tai Ahom was in use in the Mong Mao kingdom by the end of the 14th century at the latest.""There is a general consensus that the proto-Shan script that developed into the modern Shan and Ahom scripts was adapted from the Burmese script sometime between the late 14th and the 16th century. Ferlus (1988) and Diller (1992) also argue that lack of orthographic contrasts between original voiced and voiceless consonants suggests that the adaptation took place later than the first half of the 13th century. In addition, Pain (2017) adds the use of digraph ui, to represent /ɯ/ in Shan and Ahom as further evidence for the Old Burmese origin. Furthermore, Daniel’s (2012) analysis of the 1407 manuscript discussed above postulates that the adaptation occurred in the 14th century. The shapes of 14 letters attested in the text as well as the use of diacritical -y-, -r-, and -w- points to an Old Burmese origin." Scholars have further argued from pre-Ahom inscriptional and Buranji evidence that settled agriculture, wet-rice cultivation and embankment-based water management had important antecedents in Assam before the Ahom entry"Incidentally, in pre-Ahom Assam the whole economic set-up was contingent on wet-rice cultivation...So, wet-rice cultivation with an irrigation technology dependent on the construction of alis was a common feature of the pre-Ahom rural landscape.""That agriculture was the mainstay of the society can be inferred from epigraphic evidence. Dhanya (rice or paddy) was the staple crop. Cultivation of rice was mostly done following the wet rice cultivation technique. Inscriptions record the existence of surplus agricultural production, one of the essential pre-requisite for an urban economy. Inscriptions throw light on the productive capacity of the granted lands, as well as the names of various categories of land." and that groups like Kacharis already practised wet-rice cultivation when the Ahoms settled in Assam."Maringkhowa Bahbariya Barchetia Gohain was asked to confiscate the rice fields of the Kacharis. From this and other evidence, it is clear that rice cultivation was practised in the Lauhitya valley much before the Tai-Ahoms settled there. This was reported to the Tai-Ahoms by the Barahi chief. The Kacharis had devised a way to build embankments to divert water into channals, thereby creating areas where paddy cultivation was possible. Such a system allowed for more than subsistence-level agriculture. The production of rice-beer was an established Kachari tradition when the Tai-Ahoms occupied their riverine fields. In contrast to the Kacharis, the Morans and the Barahis were mostly gatherers and petty traders.""From the beginning, the Tai-Ahom and Kachari relationship was determined by the struggle for control of the fertile riverine Dikhoumukh. The Kachari culture was a rice culture. Through their knowledge and practice of wet-rice cultivation, the Kacharis distinguished themselves from the 'wild' hunter-gatherers and nonrice cultivators." The migrant group eventually settled in the region south of the Brahmaputra River and to the east of the Dikhow River, and established the Ahom kingdom, which over the following centuries, expanded across much of the Brahmaputra Valley until 1826. The Ahom still live in this region as of 1996.
Initial formation in Assam The followers of Sukaphaa moved about for nearly thirty years and mixed with the local population. He moved from place to place, searching for a seat. He made peace with the Borahi and Moran ethnic groups, and he and his mostly male followers married into them, creating an admixed population identified as Ahoms and initiating the process of Ahomisation. The Borahis, a Tibeto-Burman people, were completely subsumed into the Ahom fold, though the Moran maintained their independent ethnicity. Sukaphaa established his capital at Charaideo near present-day Sivasagar.
Ahomisation
The Ahoms believed that they were divinely ordained to cultivate fallow land with their techniques of wet-rice cultivation, and to bring stateless peoples into their civilisation. They were also conscious of their numerical minority. As the Ahom migrated to Assam, members of the army took wives from non-Tai-speaking populations which they encountered. As a result, the Ahom polity initially absorbed Naga, Borahi and Moran, and later large sections of the Chutia and the Dimasa-Kachari peoples. This process of Ahomisation went on until the mid-16th century, when the Ahom society itself came under direct Hindu influence. The Buranjis record the ceremonial adoption of indigenous peoples into Ahom clans."Thus the illustrious Ahom family of Miri Sandikai was founded by one Miri (Mising), the adopted son of a Burhagohain. (Purani Asam Buranji) King Gadadhar Sinha (1681-1696) accepted two Naga princesses as his consorts. (Tungkhungiya Buranji) The new converts, if possessed of efficiency, were even recruited to important administrative posts. Thus the second Barphukan, the governor of Lower Assam, was the son of a Naga of Banferra clan. (Purani Asam Buranji) Queen Phuleswari, who took the regalia to her hand during the reign of king Siva Singha (1714-1744), appointed a Bhutanese youth as her page. Kancheng, the first Barpatra Gohain was born and brought up in a Naga family. (Purani Asam Buranji)" Since the Ahoms married outside their own clans and since their own traditional religion resembled the religious practices of the indigenous peoples, the assimilation under Ahomisation had little impediment.
