Anushilan Samiti
By 1902, Calcutta had three secret societies working toward the violent overthrow of British rule in India. One was founded by Calcutta student Satish Chandra Basu with the patronage of Calcutta barrister Pramatha Mitra, another was led by Bengali woman Sarala Devi and the third was founded by Aurobindo Ghosh. Ghosh was one of the strongest proponents of militant Indian nationalism at the time. By 1905 the work of Aurobindo and his brother, Barin, enabled Anushilan Samity to spread throughout Bengal. Nationalist writings and publications by Aurobindo and Barin, including "Bande Mataram" and "Jugantar", had a widespread influence on Bengal youth. The 1905 partition of Bengal stimulated radical nationalist sentiments in Bengal's Bhadralok community, helping Anushilan acquire a support base of educated, politically-conscious and disaffected members of local youth societies. Its program emphasized physical training, training its recruits with daggers and "lathis" (bamboo staffs used as weapons). The Dhaka branch of Anushilan was led by Pulin Behari Das, and branches spread throughout East Bengal and Assam. More than 500 branches were opened in eastern Bengal and Assam, linked by "close and detailed organization" to Pulin's headquarters at Dhaka. It absorbed smaller groups in the province, soon overshadowing its parent organisation in Calcutta. Branches of Dhaka Anushilan emerged in Jessore, Khulna, Faridpur, Rajnagar, Rajendrapur, Mohanpur, Barvali and Bakarganj. Estimates of Dhaka Anushilan Samiti's reach indicate a membership of 15,000 to 20,000. Within two years, Dhaka Anushilan devolved its aims from the Swadeshi to that of political terrorism.
History of Bengal
Bengal played a major role in the Indian independence movement (including the Pakistan movement), in which revolutionary groups such as Anushilan Samiti and Jugantar were dominant. Bengalis also played a notable role in the Indian independence movement. Many of the early proponents of independence, and subsequent leaders in movement were Bengalis. Among the Hindu independence leaders from Bengal were Chittaranjan Das, Surendranath Banerjee, Netaji Subhas Chandra Bose, Prafulla Chaki, Bagha Jatin, Khudiram Bose, Surya Sen, Binoy–Badal–Dinesh, Sarojini Naidu, Aurobindo Ghosh, Rashbehari Bose and many more. Some of these leaders, such as Netaji, did not subscribe to the view that non-violent civil disobedience was the only way to achieve Indian Independence, and allied with Japan to fight against the British. During the Second World War Netaji escaped to Germany from house arrest in India and there he founded the Indian Legion an army to fight against the British Government, but the turning of the war compelled him to come to South-East Asia and there he became the co-founder and leader of the Indian National Army (distinct from the army of British India) that challenged British forces in several parts of India. He was also the head of state of a parallel regime named 'The Provisional Government of Free India' or Arzi Hukumat-e-Azad Hind, that was recognised and supported by the Axis powers. Bengal was also the fostering ground for several prominent revolutionary organisations, the most notable of which was Anushilan Samiti. A large number of Bengalis died in the independence struggle and many were exiled in Cellular Jail, the much dreaded prison located in Andaman.
