When the war of attrition between both continued unabated, the Soviet Communists intervened. The warring leaders were invited to Russia for a discussion with the Communist Party of the Soviet Union (CPSU) in 1951. Events that followed were described Mohit Sen thus:Four leaders, two from each center, were brought to Moscow. They travelled in cognito as manual workers in a Soviet ship from Calcutta. They were Ajoy Ghosh and S.A. Dange from the 'Indian Path', and C. Rajeswara Rao and M. Basava Punnaiah, from the Chinese path. Stalin's view also was that India was not an independent country but ruled indirectly by British colonialists. He also agreed that the Communists could eventually advance only by heading an armed revolution. But this would not be of the Chinese type. He strongly advised that the armed struggle being conducted in Telangana should be ended. In 1951, Dange was elected to both the Central Committee and the Politburo. In 1952 Dange lost elections to the Indian Parliament from Bombay. In mid-1955, Jawaharlal Nehru, the then Indian Prime Minister visited USSR and received a tremendous welcome. This was followed by the maiden visit to India of the Soviet leaders, Nikolai Bulganin and Nikita Khrushchev in 1955. Jawaharlal Nehru, frankly put forward to the visiting Soviet leaders that the Communist Party of India was claiming to receive direction from the CPSU. To this Khrushchev's response was a reiteration of the official Soviet Party line, that with the abolition of the Comintern, there was no organisation for leading the Communist Parties in other countries. Khrushchev and Bulganin's visit paved way for forging of a strong relationship between the Government of India (and later Congress Party) and the USSR, independent of CPI. The party was again on the verge of split at its fourth congress held at Palakkad in 1956. Against the ultra-left line of Ranadive, Dange and P.C. Joshi were for reviving the 'popular front' and working with the ruling Indian National Congress. These differences within the Communist Party of India, up to Palakkad congress was an internal matter of the Party; the international communist movement at that time was united. Ranadive who was earlier shunned for his extremism made a comeback to the Party leadership at the Palakkad congress. After India's independence in 1947, the princely states were integrated into the Indian Union, and the Deccan States including Kolhapur were integrated into Bombay State, which was created from the former Bombay Presidency in 1950.
