Raja Rammohun Roy (22 May 1774 – 27 September 1833) was one of the founders of the Brahmo Sabha, the precursor of the Brahmo Samaj, a social-religious reform movement in the Indian subcontinent. He was given the title of Raja by Akbar II, the Mughal emperor.
His influence was apparent in the fields of politics, public administration, education and religion. He was known for his efforts to abolish the practices of sati and child marriage. Raja Rammohun Roy is considered to be the “Father of the Bengal Renaissance” by many historians.
