evidence: The Constitution (Scheduled Tribes) (Part C States) Order, 1951 included "any Kuki tribe", "any Lushai tribe" and "any Naga tribe" (as umbrella terms among the scheduled tribes in Assam, Manipur, and Tripura. Among the "any Kuki" classification, it listed 39 subtribes/clans.[55][56][57] The 1951 census recorded the Kuki population of Manipur as 69,855, that in Assam as 18,200,[f] and that in Tripura as 3,428.[32] The 21 Kuki tribes of Manipur (as per the nomenclature used in the British colonial times) gathered together in 1948 to form an organisation called Kuki Company. They also contributed to the construction of Kuki Inn in Imphal, to serve as the office for the organisation. Soon afterwards, frictions developed over the use of the Thadou language for the business of the organisation.[g] As a result, almost all the tribes other than Thadou Kukis left the Kuki Company, and formed a separate Khulmi National Union.[58] In 1950s, ten Old Kuki tribes changed their affiliation to 'Naga', induced to do so by the Tangkhuls.[h] Seven New Kuki tribes eventually adopted the Zomi identity in the 1990s.[60]
