Secession in India typically refers to state secession, which is the withdrawal of one or more states from the Republic of India. Some have argued for secession as a natural right of revolution. Some state movements seek secession from India itself and the formation of a new nation from one or more states. Their underlying root causes are invariably to be found in political, socio-economic, or religious domains; their nature and scope depending upon the nature of the grievances, motivations and demands of the people. In all, an estimated 30 armed insurgency movements are sweeping across India, reflecting an acute sense of alienation on the part of the people involved. Broadly, these can be divided into movements for political rights (e.g. Assam, Kashmir and Khalistan [Punjab]), movements for social and economic justice (e.g. Maoist [Naxalite] and north-eastern states), and religious grounds (e.g. Laddakh). These causes overlap at times.
Many separatist movements exist with thousands of members, however, with moderate local support and high voter participation in the democratic elections. The Khalistan movement in Punjab was active in the 1980s and the 1990s, but is now largely subdued within India. Insurgency has occurred in North-East India, in the states of Tripura, Meghalaya, Mizoram, Manipur, Assam and Nagaland.
India has introduced several Armed Forces Special Powers Acts (AFSPA) to subdue separatist movements in certain parts of the country. The law was first enforced in Manipur and later enforced in other insurgency-ridden north-eastern states. It was extended to most parts of Indian-administered Kashmir in 1990 after the outbreak of an armed insurgency in 1989. Each Act gives soldiers immunity in specified regions against prosecution unless the Indian government gives prior sanction for such prosecution. The government maintains that the AFSPA is necessary to restore order in regions like Kashmir and Manipur.
