The Ahom Kingdom (/ˈɑːhɑːm, ˈɑːhəm/; Assamese: আহোম ৰাজ্য) (1228–1826) was a kingdom in the Brahmaputra valley in Assam, India that maintained its sovereignty for nearly 600 years and successfully resisted Mughal expansion in North-East India. Established by Sukaphaa, a Tai prince from Mong Mao, it began as a Mong in the upper reaches of the Brahmaputra river based on wet rice cultivation. It expanded suddenly under Suhungmung in the 16th century and became multi-ethnic in character, casting a profound effect on the political and social life in the entire Brahmaputra valley. The kingdom became weaker with the rise of the Moamoria rebellion, and subsequently fell to a succession of Burmese invasions.
