Explanation: The Communist Party of India (CPI) was formed in 1920 in Tashkent (now, the capital of Uzbekistan) by M.N. Roy, Abani Mukherji and others after the second Congress of Commintern.

M.N. Roy was also the first to be elected to the leadership of Commintern.

In 1924, many communists—S.A. Dange, Muzaffar Ahmed, Shaukat Usmani, Nalini Gupta—were jailed in the Kanpur Bolshevik Conspiracy Case.
