A Naxal or Naxalites is a member of any of the Communist guerrilla groups in India, mostly associated with 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 and Andhra Pradesh through the activities of underground groups like the Communist Party of India (Maoist).
