In the meantime, the Reangs formed a militant organization on the style of United Liberation Front of Assam (ULFA), in the name of United Liberation Front of Barak Valley (ULFBV), to get their demands fulfilled. This organization was formed in the year 2001 and its area of operation was the districts of Hailakandi and Karimganj of Assam. They had started looting, kidnapping of businessmen for ransom. The aims and objectives of the ULFBV were to protect the Reang community and safeguard the interest of the community against the atrocities of the Mizos and the Muslims.
The organization also demanded a separate Zila Parishad for the tribal community in the Barak Valley. The Reangs demanded the restoration of land to the tribal people.
Among their various demands was also demand for payment of ex-gratia to their activists who lost their lives. Their demand included general amnesty and peace negotiation process to be done at the ministry level in presence of Central home ministry representative.
The ULFBV declared unilateral cease-fire with effect from 7th June 2008, with a view to solve their problems through negotiations with the government. Their cadres surrendered on 30th September 2008 at a function held at Guwahati and deposited large number of arms and ammunition at the time of joining the main stream.
It may be mentioned here that ever since the Reangs, the minority community in Mizoram raised their voice for an autonomous council for themselves under the Sixth Schedule of the Constitution of India and re-entry of deleted names in the electoral rolls, they were subjected to unbearable oppressions by the MSA and MZP. The predicament of the Reangs began long ago when Mizos compelled them to get converted to Christianity. Although a number of them succumbed to such pressure, it did not improve their status. About sixty percent of them had been converted and forced to accept Mizo names and language as medium of education. Their culture practices were obstructed and they found their identity being threatened by the Mizos. About twenty thousand Reangs were alleged to have deprived of their rights to franchise through deleting their names from the voters list of Mizoram.
