After the British took control of the region, the name Assam was extended to the province that was then much larger than the Ahom kingdom. It then included, Garo Hills and Lushai Hills (Mizoram). Since that time, the boundaries of Assam have been repeatedly redrawn, though the name Assam remained. Today, the political boundary of Assam contains roughly the historical Ahom Kingdom and its protectorates, the Kachari kingdom, Koch Hajo and a part of the Jaintia Kingdom.
