Kanpur Conspiracy Case 1924:

• Narendra Nath Bhattacharya famously known as M.N. Roy founded  Mexican Communist Party and the Communist Party of India. In 1924 the communist thoughts were at peak in India and Indian youth were joining communist party in massive numbers.
  In the meantime, Some newly turned communists named M N Roy, Muzaffar Ahamed, S A Dange, Shaukat Usmani, Nalini Gupta, Singaravelu Chettiar, Ghulam Hussain were caught by the Government and were trailed for conspiring against the Government.
  The Charge on them was “to deprive the King Emperor of his sovereignty of British India, by complete separation of India from imperialistic Britain by a violent revolution.”
  This case made the communist leaders more famous and brought the communists in the lime light. The newspapers covered the matter exhaustively and this was for the first time the people of India could know the communist doctrine in details.
  This case was responsible for introduction of Communism to the Indian Public.
  M N Roy was charged in absentia and later he was arrested in 1931. Ghulam Hussain turned a British informer and was pardoned. Muzaffar Ahamed, S A Dange, Shaukat Usmani, Nalini Gupta, were arrested and sent to jail for 4 years.
