The Cellular Jail, also known as 'Kālā Pānī', was a British colonial prison in the Andaman and Nicobar Islands. The prison was used by the colonial government of India for the purpose of exiling criminals and political prisoners. Many notable independence activists, including Sardar Singh Artillery, Diwan Singh Kalepani, Yogendra Shukla, Batukeshwar Dutt, Shadan Chandra Chatterjee, Sohan Singh, Vinayak Savarkar, Hare Krishna Konar, Shiv Verma, Allama Fazl-e-Haq Khairabadi, and Sudhanshu Dasgupta were imprisoned here during the struggle for India's independence. Today, the complex serves as a national memorial monument.

Hare Krishna Konar was an Indian Marxist revolutionary, political theorist, charismatic peasant leader and politician. Konar was a founding member of the Communist Party of India (Marxist), the figurehead behind India's first land reform, and the chief architect of the West Bengal land distribution. Between the 1960s and 1970s, he became one of the principal leaders of the Communist movements in India. In 1932, due to his involvement in the Begut Robbery Case of the Jugantar Party, Konar was deported to the Cellular Jail of the Andaman for 6 years at the age of 18, there he took part in the first hunger strike and in 1935 he founded the Communist Consolidation and led the historical second hunger strike.
