The Ahom (Pron: , , , people of Assam) are the descendants of the ethnic Tai people that accompanied the Tai prince Sukaphaa into the Brahmaputra valley in 1228 and ruled the area for six centuries. Sukaphaa and his followers established the Ahom kingdom (1228–1826) and the Ahom dynasty ruled and expanded the kingdom until the British gained control of the region through the Treaty of Yandabo upon winning the First Anglo-Burmese War in 1826.
