the Dikho river; the Ahoms today are found concentrated in this region. Sukaphaa, the leader of the Tai group and his 9,000 followers established the Ahom kingdom (1228–1826 CE), which controlled much of the Bramhaputra valley until 1826. Initial formation in Assam In the initial phase, the band of 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 in 1253 and began the task of state formation. Ahomisation The Ahoms believed that they were divinely ordained to bring fallow land under the plow with their techniques of wet-rice cultivation, and to adopt stateless shifting cultivators into their fold. They were also conscious of their numerical minority. 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 the direct Hindu influence. That many indigenous peoples were ceremonially adopted into Ahom clans are recorded in the chronicles. Since the Ahoms married liberally outside their own exogamous clans and since their own traditional religion resembled the religious practices of the indigenous peoples the assimilation under Ahomisation had little impediment. Localisation and Loss In the 16th and 17th centuries, the small Ahom community expanded their rule dramatically toward the west and they successfully saw off challenges from Mughal and other invaders, gaining them recognition in world history. The rapid expansion resulted in the Ahom people becoming a small minority in their own kingdom, of which they kept control. Eventually, the Ahom court, as well as the Ahom peasants took to Ekasarana dharma, Shaktism and Saivism over the traditional Ahom religion; and adopted Assamese over the Ahom language for secular purposes. The modern Ahom people and their culture are a syncretism of the original Tai and their culture and local Tibeto-Burman peoples and their cultures they absorbed in Assam. The everyday usage of Ahom language ceased completely by
