Brahmo Samaj of India and Adi Brahmo Samaj

• Keshab Chandra Sen and his followers founded the Brahmo Samaj of India in 1866, while Debendranath Tagore’s Samaj came to be known as the Adi Brahmo Samaj.
• The split was caused because Debendranath did not like some of Sen’s ideas which he found too radical, such as cosmopolitanisation of the Samaj’s meetings by inclusion of teachings from all religions and his strong views against the caste system, even open support to inter-caste marriages.
