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.
Emperor vs Aurobindo Ghosh and others
Among the famous accused were Aurobindo Ghosh, his brother Barin Ghosh as well as 37 other Bengali nationalists of the "Anushilan Samiti". Most of the accused were arrested from Barin Ghosh's Garden house in 36 Murarirupukur Road, in the Manicktolla suburb of Calcutta. They were held in the Presidency Jail in Alipore before the trial, where Narendranath Goswami, approver and crown-witness, was shot dead by two fellow accused Kanailal Dutta and Satyendranath Bose within the jail premises. Goswami's murder led to collapse of the case against Aurobindo. However, his brother Barin and a number of others were convicted of the charges and faced varying jail terms from life-imprisonment to shorter jail terms.
