CPI was heavily involved in resistance to British colonisation, the fight against the caste system and for land reform.[11] Between 1921 and 1933, many Communist leaders were arrested and imprisoned. In 1934, the British colonial administration banned the Communist Party and its affiliated trade union and peasant organisations, making membership a criminal offence.[12] The Communist Party continued its activities clandestinely, despite the repression. Between 1946 and 1951, it structured the peasant revolt in Telangana and organised guerrilla warfare against the feudal lords.[12] CPI was the main opposition party in India during the 1950s to 1960s.[13]
