In the Indian Independence movement In 1941, Kumaramangalam was arrested along with
P. Ramamurthi, C. S. Subramaniam and R. Umanath for distributing seditious pamphlets in what came to be known as the Madras Conspiracy Case. Kumaramangalam was later released. During the
Second World War Kumaramangalam served as the editor of the communist magazine, ''People's War
, which on the conclusion of hostilities he renamed as People's Age''.
Post-independence politics In the days following India's independence Madras Presidency was gripped by a peasant rebellion, which compelled the provincial government to launch a crackdown on communists. Kumaramangalam was arrested along with other communist leaders and released after the rebellion had subsided. Kumaramangalam favoured friendly relations with the
Soviet Union and established the Indo-Soviet Cultural Society. He was the driving force behind
Indira Gandhi's decision in 1973, to appoint
Ajit Nath Ray as the
Chief Justice of India superseding three senior judges of the
Supreme Court of India -
J. M. Shelat, A.N Grover and
K. S. Hegde. == Personal life ==
