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
The void arising from the precipitous decline of the Mughal Empire from the early decades of the 18th century allowed emerging powers to grow in the Indian subcontinent. These included the Sikh Confederacy, the Maratha Confederacy, "Nizamiyat", the local nawabs of Oudh and Bengal and other smaller powers. Each was a strong regional power influenced by its religious and ethnic identity. However, the East India Company ultimately emerged as the predominant power. Amongst the results of the social, economic and political changes instituted in the country throughout the greater part of the 18th century was the growth of the Indian middle class. Although from different backgrounds and different parts of India, this middle class and its varied political leaderships contributed to a growing "Indian identity". The realisation and refinement of this concept of national identity fed a rising tide of nationalism in India in the last decades of the 1800s.
