Raja Ram Mohan Roy founded the Brahmo Samaj on 28th August 1828 to revive Indian civilization and culture in India, to stop the spread of Christianity in India and to redeem Indian society from social evils. The Brahmo Samaj is chiefly based on the Vedas and Upanishads. 

Following are the main principles of the Brahmo Samaj:

1. God is one, creator of the universe, protector of his creation, infinite and formless 

2. God should be worshipped without spiritiual traditions of a community. 

3. Deliverance from birth and death each attained by atoning for the sinful deeds and the renunciation of evil tendencies, 

4. The soul is undecayed and immortal and is responsible to God. 

5. Prayers are necessary for the elevation of soul

6. All are equal in the eyes of God and He listens to everyone’s prayers 

7. Brahmo Samaj believes in the theory of deed and reward 

8. It believes in finding out the truth. Brahmo Samaj opposes the tradition of sati system, child marriage, polygamy, untouchability and such evils as drinking and use of other intoxicants.
