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
As the Congress-led movement picked up its pace during the early 1930s, some former revolutionaries identified with the Gandhian political movement and became influential Congressmen (notably Surendra Mohan Ghose). Many Bengali Congressmen also maintained links with the Anushilan groups, and their revolutionary ideology and approach had not died away. In April 1930, Surya Sen and his associates raided the Chittagong Armoury. The Gandhi-led Salt March also saw the most active period of revolutionary terrorism in Bengal since World War I. In 1930 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 in Midnapore were assassinated, and dozens of other actions were carried out during the first half of the decade. Although by 1931 a record 92 violent incidents were recorded, including the murders of the British magistrates of Tippera and Midnapore, the terrorist movement in Bengal may be said to have ended in 1934.
