Insurgency in Northeast India

The Insurgency in Northeast India is ongoing armed conflicts in a number of India's northeastern states between several militants groups with various political ideologies, including separatism, communism and Christian nationalism, and the Indian government.

Northeast India consists of eight states: the seven sister states of Assam, Meghalaya, Tripura, Arunachal Pradesh, Mizoram, Manipur, and Nagaland, and the brother state Sikkim included later. These states are connected to the rest of India by the Siliguri Corridor, a strip of land as narrow as 14.29 miles (23.00 km) wide. Tensions have existed between insurgents in the seven sister states and the central government as well as amongst their native indigenous people and migrants from other parts of India and illegal immigrants for many decades now.

Since the middle of 2010s, insurgency in the region has seen rapid decline, with a 80% reduction in violence and an 89% drop in civilian deaths in 2022 compared to 2014. Manipur has witnessed a rise in insurgent activities ever since ethnic violence broke out in the state on 3 May 2023 between the Meitei people and the Kuki people. This has led to a new era in Manipur's insurgency where militant groups witnessed a resurgence in membership.

The 2014 Indian general election had an 80% voter turnout in all northeastern states, the highest among all states of India according to Indian government. Indian authorities claim that this shows the faith of the northeastern people in Indian democracy. Indian Chief of Defence Staff Gen Anil Chauhan then Eastern Army Commander had stated that as of 2020, the area of violence in the entire North-East has shrunk primarily to an area which is the tri-junction between Assam, Arunachal Pradesh and north Nagaland.
