evidence: It is a fact, from 15th century Kabaw Valley was in the possession of Manipur till 1834 except for some periodical occupation by Burmese now and then, which the Manipuri King destroyed by war and established the legitimate right and at the same time right by conquest. James Johnstone has stated that Manipur held a considerable territory east of the Chindwin River in subjection, at other times only the Kabaw Valley, a strip of land, inhabited not by Burmese, but by Shans, and lying between Manipur proper and the Chindwin. For the greater part of 18th century, the Kabaw Valley unquestionably belonged to Manipur, and it was never in any sense a Burmese province, a feudatory of great Shan kingdom of Pong. [Gangmumei Kabui 1983:81] [...] Bhyagachandra (1762-99) made a marathon struggle to drive away the Burmese and recover the kingdom of Manipur. In 1813, Marjit Singh became king of Manipur; his popularity plummeted for accepting Burmese suzerainty and ceding Kabaw Valley to Burma. He also promised to renounce all the claims over the Kabaw Valley. [Gangmumei Kabui 1988:25; Sanajaoba 1993:43] Thus, Kabaw valley was in the possession of Burma from 1813 to 1825, for twelve years.
