Political history of Sri Aurobindo
Anushilan Samiti was founded as an attempt to organize Bengali youth through a program of physical fitness and spiritual training for a nationalist program. By 1902, Calcutta had three societies working under the umbrella of Anushilan Samity, a society earlier founded by a Calcutta barrister by the name of Pramatha Mitra. These included Mitra's own group, another led by a Bengali lady by the name of Sarala Devi, and a third one led by Aurobindo Ghosh. The Anushilan Samiti had Aurobindo and Deshabandhu Chittaranjan Das as the vice-presidents, Suren Tagore the treasurer. Jatindra Nath Banerjee (Niralamba Swami), Bagha Jatin, Bhupendra Nath Datta (Swami Vivekananda's brother), Barindra Ghosh were among other initial leaders.
By 1905, the work of Aurobindo and his brother Barin Ghosh allowed Anushilan Samity to spread through Bengal.
History of the Anushilan Samiti
As Congress-led movement picked up pace in the early thirties, some former revolutionaries identified with Gandhian political movement and became influential Congressmen, notably among them Surendra Mohan Ghose. Many Bengal Congressmen also maintained links with the Anushilan groups. Anushilan's revolutionary ideology and approach had not, in the meantime, died away. In April 1930, Surya Sen and his associates raided the Chittagong Armoury. The Gandhi-led Civil Disobedience Movement also saw the most active period of revolutionary terrorism in Bengal after first world war. During 1930 alone eleven British officials were killed, notably during the Writer’s Building raid of December 1930 BY Benoy Basu, Dinesh Gupta and Badal Gupta. Three successive District Magistrates of Midnapore were assassinated and dozens of other successful actions were carried out during the first half of the decade. But this was a last flare-up before the fire was extinguished. The terrorist movement in Bengal may be said to have ended in 1934.
