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.
Ayyavazhi
Arul Nool, the first Ayyavazhi work in print was released in 1927, followed by the Akilam in 1933, almost a century after it had been written down. As a result, Ayyavazhi abandoned active oral traditions in favor of literary scriptures. Ayyavazhi headquarter reports that Ayyavazhi spread more rapidly after Indian Independence (1940s) and still more rapidly through the 1990s. Many Ayyavazhi-based social welfare organisations were established in the late 20th century. Several alternative versions of Akilam, including some controversial versions, were released during the same period. The Anbukkodimakkal Thirucchabai, a democratic bureau, was established by the religious headquarters in the early 1990s to organize and govern the religion. Organisational conferences are held in various cities in South India including Mumbai, Chennai and Thiruvananthapuram.
