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.
Dalit Buddhist movement
Achhutanand was born in an untouchable family, joined the Arya Samaj "suddhi" reform movement, worked there for about eight years (1905-1912), felt untouchability was being practiced in Arya Samaj in subtle ways, left it and launched Bharitiya Achhut Mahasabha as a socio-political movement. Achhutanand began spreading his ideas by publishing the Adi-Hindu magazine, and called Dalits to a return to Adi-Dharma as the original religion of Indians. Achhutanand formulated his philosophy on the basis of a shared cultural and ethnic identity, presenting it to an audience beyond the Dalits and including tribal societies as well. He opposed the non-cooperation movement of Mahatma Gandhi, his fasts and Indian National Congress, stating that the Brahmins were "as foreign to India as were the British", according to Anand Teltumbde.
