A Naxal or Naxalite is a member of the Communist Party of India (Maoist). The term Naxal derives from the name of the village Naxalbari in West Bengal, where the movement had its origin. Naxalites are considered far-left radical communists, supportive of Maoist political sentiment and ideology. Their origin can be traced to the split in 1967 of the Communist Party of India (Marxist), leading to the formation of the Communist Party of India (Marxist–Leninist). Initially the movement had its centre in West Bengal. In later years, it spread into less developed areas of rural southern and eastern India, such as Chhattisgarh, Odisha, Andhra Pradesh and Telangana through the activities of underground groups like the Communist Party of India (Maoist).
According to Maoist sympathisers, the Indian Constitution "ratified colonial policy and made the state custodian of tribal homelands", turning tribal populations into squatters on their own land and denied them their traditional rights to forest produce. These Naxalite conflicts began in the late 1960s with the prolonged failure of the Indian government to implement constitutional reforms to provide for limited tribal autonomy with respect to natural resources on their lands, e.g. pharmaceutical and mining, as well as pass 'land ceiling laws', limiting the land to be possessed by landlords and distribution of excess land to landless farmers and labourers. In Scheduled Tribes [ST] areas, disputes related to illegal alienation of ST land to non-tribal people, still common, gave rise to the Naxalite movement.
Between 2002 and 2006, over three thousand people had been killed in Naxalite-Government conflicts, and by 2009, the conflict had displaced 350,000 members of tribal groups from their ancestral lands.
In 2006 India's intelligence agency, the Research and Analysis Wing, estimated that 20,000 armed-cadre Naxalites were operating in addition to 50,000 regular cadres. Their growing influence prompted Indian Prime Minister Manmohan Singh to declare them to be the most serious internal threat to India's national security. Naxalites, and other anti-government militants, are often referred to as "ultras".
