BRAHMA SAMAJ, a religious association in India which owes its origin to (Raja) Ram Mohan Roy, who began teaching and writing in Calcutta soon after 1800.
Impressed with the perversions and corruptions of popular Hinduism, Ram Mohan Roy investigated the Hindu Shastras, the Koran and the Bible, repudiated the polytheistic worship of the Shastras as false, and inculcated the reformed principles of monotheism as found in the ancient Upanishads of the Vedas.
Ram Mohan Roy soon after left India for England, and took up his residence in Bristol, where he died in 1835.
Debendra Nath Tagore sought refuge from the difficulty by becoming an ascetic. The "Brahma Samaj of India," as Chunder Sen's party styled itself, made considerable progress extensively and intensively until 1878, when a number of the most prominent adherents, led by Anand Mohan Bose, took umbrage at Chunder Sen's despotic rule and at his disregard of the society's regulations concerning child marriage.
