Anushilan Samiti
Anushilan Samiti (Ōnūshīlōn sōmītī, "lit": body-building society) was a Bengali Indian organisation that existed in the first quarter of the twentieth century, and propounded revolutionary violence as the means for ending British rule in India. The organisation arose from a conglomeration of local youth groups and gyms ("Akhara") in Bengal in 1902. It had two prominent, if somewhat independent, arms in East and West Bengal identified as Dhaka Anushilan Samiti centred in Dhaka (modern day Bangladesh), and the Jugantar group (centred at Calcutta) respectively.
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.
