Dissatisfaction and anger due to government opposition to their demands led the PCJSS to organise the Shanti Bahini (Peace forces) as military force to launch an armed struggle to win autonomy and secure the rights of the people of the Hill Tracts. Many insurgents are believed to have trained, equipped and sheltered in the neighbouring Indian state of Tripura. During the insurgency, the PCJSS strongly opposed the government-driven settlement of Bengalis in the Hill Tracts as a ploy to marginalise the tribes in their home region. The PCJSS also rejected the Chittagong Hill Tracts Development Board and other government plans for local councils. After an insurgency that lasted for almost two decades, the PCJSS entered into peace talks with the government after the restoration of democracy in 1991. However, little progress was made with the government of prime minister Begum Khaleda Zia, the widow of Ziaur Rahman and her Bangladesh Nationalist Party. Fresh rounds of talks began in 1996 with the newly elected prime minister Sheikh Hasina Wajed of the Awami League, the daughter of Sheikh Mujib. The peace accord was finalised and formally signed on 2 December 1997. The peace accord provided for greater autonomy, the return of land to displaced tribals and special status for the ethnic groups and tribes. The accord also created a central ministry of tribal affairs and an elected regional council that would be empowered to govern the Hill Tracts and oversee local tribal councils. The accord also granted official recognition of the ethnic groups and tribes.
