Raja Ram Mohan Roy established the Brahma Samaj on 20 August, 1829. This Samaj tried to prevent the influence of Christian religion in India. It opposed untouchability, child marriage, polygamy, intoxication, idol worship and Sati pratha. It was in favour of widow marriage. Brahmo Samaj got the law passed against Sati pratha and this custom was declared illegal. Besides it, Brahmo Samaj was in favour of widow marriage. It believed in the principles of Karma, and opposed idol worship, casteism and animal sacrifice.
