Founded in 1828 by Raja Ram Mohan Roy in Calcutta, the Brahmo Samaj is a religious movement. At its centre is the belief that there is one God, who is omni-present and omniscient. It initially evolved in India where it differed from existing practice as it did not believe in idol-worship or the caste system. The Brahmo religion is now practised in many parts of the world.
The Brahmo Samaj has played a significant role in the renaissance of India, and the roots of much of the modern thinking in India can be traced back to the Brahmo movement. Rabindranath Tagore, the Nobel Laureate, was one of the luminaries of the Brahmo Samaj.
