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
The growth of the Indian middle class during the 18th century, amidst competition among regional powers and the ascendancy of the British East India Company, led to a growing sense of "Indian" identity. The refinement of this perspective fed a rising tide of nationalism in India in the last decades of the 1800s. Its speed was abetted by the creation of the Indian National Congress in India in 1885 by A.O. Hume. The Congress developed into a major platform for the demands of political liberalisation, increased autonomy and social reform. However, the nationalist movement became particularly strong, radical and violent in Bengal and, later, in Punjab. Notable, if smaller, movements also appeared in Maharashtra, Madras and other areas in the South. The movement in Maharshtra, especially Bombay and Poona preceded most revolutionary movements in the country. This movement, further, had the ideological, and by some suggestion covert but active, support of Bal Gangadhar Tilak. 1876 saw the foundation of The Indian Association in Calcutta under the leadership of Surendranath Banerjea. This organisation successfully drew into its folds students and the urban middle–class, for which it served as a mouthpiece. The Association became the mouthpiece of an informal constituency of students and middle-class gentlemen. It sponsored the Indian National Conference in 1883 and 1885, which later merged with the Indian National Congress. Calcutta was at the time the most prominent centre for organised politics, and some of the same students who attended the political meetings began at the time to organise "secret societies" which cultivated a cultural of physical strength and nationalist feelings.
