The founder of ‘Brahmo Samaj of India’ was Keshav Chandra Sen.
Devendra Nath stripped the title of ‘Acharya’ from Keshav Chandra in 1865.
Hence Keshav Chandra Sen came out from original Brahmo Samaj and group under the influence of Devendra Nath Tagore called themselves as ‘Adi Brahmo Samaj.’
The group under the leadership of Keshav Chandra Sen called themselves as ‘Bhartiya Brahmo Samaj’ or ‘Neo Brahmo Samaj.’
Again in 1878, ‘ Navin Brahmo Samaj’ was further divided when Keshav Chandra Sen got his 13 year-old daughter married with the king of Kooch, Bihar.
To oppose his action, Anand Mohan Bose and Shivnath Shastri formed ‘Sadharan Brahmo Samaj.’
