Naxalbari uprising

Main article: Naxalite

At this point the party stood at crossroads. There were radical sections of the party who were wary of the increasing parliamentary focus of the party leadership, especially after the electoral victories in West Bengal and Kerala. Developments in China also affected the situation inside the party. In West Bengal two separate internal dissident tendencies emerged, which both could be identified as supporting the Chinese line.^[12] In 1967 a peasant uprising broke out in Naxalbari, in northern West Bengal. The insurgency was led by hardline district-level CPI(M) leaders Charu Majumdar and Kanu Sanyal. The hardliners within CPI(M) saw the Naxalbari uprising as the spark that would ignite the Indian revolution. The Communist Party of China hailed the Naxalbari movement, causing an abrupt break in CPI(M)-CPC relations.^[13] The Naxalbari movement was violently repressed by the West Bengal government, of which CPI(M) was a major partner. Within the party, the hardliners rallied around an All India Coordination Committee of Communist Revolutionaries. Following the 1968 Burdwan plenum of CPI(M) (held on April 5–12, 1968), the AICCCR separated themselves from CPI(M). This split divided the party throughout the country. But notably in West Bengal, which was the centre of the violent radicalist stream, no prominent leading figure left the party. The party and theNaxalites (as the rebels were called) were soon to get into a bloody feud.

In Andhra Pradesh another revolt was taking place. There the pro-Naxalbari dissidents had not established any presence. But in the party organisation there were many veterans from the Telangana armed struggle, who rallied against the central party leadership. In Andhra Pradesh the radicals had a strong base even amongst the state-level leadership. The main leader of the radical tendency wasT. Nagi Reddy, a member of the state legislative assembly. On June 15, 1968 the leaders of the radical tendency published a press statement outlining the critique of the development of CPI(M). It was signed by T. Nagi Reddy, D.V. Rao, Kolla Venkaiah and Chandra Pulla Reddy.^[14] In total around 50% of the party cadres in Andhra Pradesh left the party to form the Andhra Pradesh Coordination Committee of Communist Revolutionaries, under the leadership of T. Nagi Reddy.^[15]
