The Kanpur Bolshevik conspiracy case in 1924 was a controversial trial initiated by the British government against early communist leaders in India. The main individuals accused and subsequently jailed in this case were Muzaffar Ahmad, S. A. Dange, Shaukat Usmani, and Nalini Gupta. These individuals were pioneers of the communist movement in India and were charged with conspiracy to wage war against the King-Emperor.
– The case targeted prominent early communists in India.
– The objective was to suppress the burgeoning communist movement.
Several other individuals were named in the FIR but were not arrested or tried, including M.N. Roy. The case brought national attention to the communist movement and its leaders, despite being seen by many as a politically motivated trial intended to curb anti-colonial activities linked to socialist or communist ideas.
