In 1951, the Communist Party of India (CPI) which had been waging an armed struggle during 1948–51, gave up the attempt to wrest power through force and joined the political mainstream. At the 1951 congress of the party, "People's Democracy" was replaced by "National Democracy" as the main slogan of the party and the decision was made to contest the elections. One of the armed movements supported by the CPI was the Telangana Rebellion in the princely state of Hyderabad. Though the rebellion was crushed by 1951, the communists retained widespread support in the neighboring Andhra region. This was due to their policy of linguistic nationalism (the demand for a separate state of Telugu speaking people) and their support base amongst the Kamma caste which was opposed to the Reddy supported Congress. Till then, all the previous elections had been conducted on a limited franchise based on property ownership qualifications. The election of 1951 was the first one to be based on a universal franchise. The Communists had the support of most of the first time voters – landless peasants and agricultural labourers. They also had a strong presence in the agrarian district of Tanjore in Tamil Nadu where they were supported by the Dravidar Kazhagam.
