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.
Anushilan Samiti
Anushilan's campaign continued. In 1911 Dhaka Anushilan shot dead Sub-inspector Raj Kumar and Inspector Man Mohan Ghosh, two Bengali police officers investigating unrests linked to the group, in Mymensingh and Barisal. This was followed by the assassination of CID head constable Shrish Chandra Dey in Calcutta. In February 1911 Jugantar bombed a car in Calcutta, mistaking an Englishman for police officer Godfrey Denham. Rash Behari Bose (described as "the most dangerous revolutionary in India") extended the group's reach into north India, where he found work in the Indian Forest Institute in Dehra Dun. Bose forged links forming with radical nationalists in Punjab and the United Provinces, including those later connected to Har Dayal. During the 1912 transfer of the imperial capital to New Delhi, Viceroy Charles Hardinge's "howdah" was bombed; his "mahout" was killed, and Lady Hardinge was injured.
