Ahom Kingdom

The Ahom kingdom, or Kingdom of Assam, was a late medieval kingdom in the Brahmaputra Valley that existed for 598 years from 1228 until 1826 and came to incorporate large parts of modern Assam. Established by Sukaphaa, a Tai prince from Möng Mao, it began as a small Mueang in the upper reaches of the Brahmaputra based on wet rice agriculture. The kingdom expanded under Suhungmung in the 16th century, and became multi-ethnic in character, accelerating a process of social change, ethnogenesis, and inter-ethnic interactions under the ruling Ahom dynasty. During the 17th century, the kingdom defeated multiple attempts by the Mughal Empire to expand into Northeast India. Central authority collapsed following the Moamoria rebellion in the late 18th century. Internal conflicts between dynastic claimants led to Burmese intervention, and the kingdom faced multiple Burmese invasions after 1817. British intervention led to the First Anglo-Burmese War, and the control of the kingdom passed into the hands of the East India Company through the Treaty of Yandabo in 1826.
