From 1977, indigenous Jumma groups organized under the PCJSS and its armed wing the Shanti Bahini waged an insurgency against the Bangladeshi government over autonomy and land rights, following government settlement of hundreds of thousands of Bengali migrants into the region between 1979 and 1985.[1] Casualty and displacement figures vary widely, including reports of over 6,000 combatant deaths, 3,500-25,000 civilian deaths, and around 30,000 total documented deaths.[2] A 1989 District Council Act created limited local government structures, which the PCJSS considered insufficient.[3] On 2 December 1997, the government and the PCJSS signed the Chittagong Hill Tracts Peace Accord, establishing a CHT Regional Council with substantial devolved powers, described as the highest level of autonomy possible short of independence.[4] More recently, around 2021-2022, a distinct armed group, the Kuki-Chin National Front, emerged among different ethnic communities in Bandarban demanding a separate state, with Bangladeshi security operations against it ongoing since October 2022.[5]
