The Tibeto-Burman Chin peoples entered the Chin Hills sometime in the first millennium AD, as part of the wider migration of Tibeto-Burman peoples into the area. The first confirmed political entity in the region was the Shan city state of Kale (Kalay), founded by the Shan after the fall of Pagan Kingdom in 1287. The entire Chin Hills came under the authority of Myanmar kingdoms between 1555 and 1559 when King Bayinnaung of Taungoo Dynasty conquered all of Upper Burma and its surrounding regions stretching from the eastern and northern Shan states to the western Chin Hills and Manipur. The British acquired the Chin Hills after the Third Anglo-Burmese War of 1885. The ensuing Chin resistance to the British was suppressed only by 1890. American missionaries began arriving in the 1890s and by the middle of 20th century, most of the Chin people had converted in to Christianity.

The British first conquered Myanmar in 1824, established rule in 1886, and remained in power until Burma’s independence in 1948. The 1886 Chin Hills Regulation Act stated that the British would govern the Chins separately from the rest of Burma, which allowed for traditional Chin chiefs to remain in power. Burma’s independence from Britain in 1948 coincided with the Chin people adopting a democratic government rather than continuing its traditional rule of chiefs. Chin National Day is celebrated on February 20, the day that marks the transition from traditional to democratic rule in Chin State.
