The rebel activity continued in many Naga inhabited areas both in India and Burma. Cease-fires were announced and negotiations continued, but this did little to stop the violence. In March 1975, a direct presidential rule was imposed by the then Prime Minister Indira Gandhi on the state. In November 1975, some leaders of largest rebellion groups agreed to lay down their arms and accept the Indian constitution, a small group did not agree and continued their insurgent activity. The Nagaland Baptist Church Council played an important role by initiating peace efforts in the 1960s. This took concrete and positive shape during its Convention in early 1964. It formed the Nagaland Peace Council in 1972. However, these efforts have not completely ended the inter-factional violence. In 2012, the state's leaders approached Indian central government to seek a political means for a sense of lasting peace within the state.
