The ideas and their propagation soon produced the desired result. There were efforts to bring changes in the caste system, position of women and the system of education. The reforms for which Rammohun Roy stood were eradication of the kulin system (marriage of young girls to higher subcaste Brahmins, often much older, resulting in the practice of polygamy), stopping the sale of young girls in marriage, abolition of cast system, introduction of widow remarriage and abolition of sati. Sati was a prevailing practice among the high caste Hindus where the widow had to die, at times forcibly, ,along with the dead husband on the latter's funeral pyre. Rammohun Roy considered this cruel practice to have no sanction in the shastras. He and his friends led an agitation, which finally resulted in Sati being banned by Legislative Council Act of 1928. Rammohun Roy also engaged the Christian missionaries in public debates over their attacks on oriental religions. He criticised the missionaries for presenting a caricatured version of Christianity and distorting its essence. His attack was from the standpoint of religious universalism. He established the Brahmo Samaj in 1828 to provide space for all those who believed in non sectarian religion. He did in 1833 in Bristol, England. The Brahmo Samaj became the nucleus of reform activities in Bengal and throughout India.
