The Bengali Renaissance refers to a socio-cultural and religious reform movement during the nineteenth and early twentieth century in undivided India's Bengal province, though the impact of it spread in the whole of India. The Bengal Renaissance is said to have begun with Raja Ram Mohan Roy (1775–1833) and continued until the death of Rabindranath Tagore in 1941.The Renaissance was a revival of the positives of India's past and appreciation of the impact of the Modern West, as it had emerged since the Fifteenth-century European Renaissance. Thus, the Bengal Renaissance blended together the teachings of the Upanishad in order to create public opinion against Hindu superstitions including Sati, infanticide, polygamy, child marriage, caste-division, inter-caste hatred, Dowry, untouchability etc. and the efforts of the Christian Missionaries and the British Colonial Government who introduced Western varieties of education, politics and law to administer all those who indulged in superstitions and caste-based Hindu medievalism.
During this period, Bengal witnessed an intellectual awakening questioning the prevalent orthodoxies concerning the social status of women, marriage, the caste system, superstitious beliefs and religion. One of the earliest social movements that emerged during this time was the Young Bengal movement, that espoused rationalism and atheism as the common denominators of civil conduct among upper caste educated Hindus.
The parallel socio-religious movement, Brahmo Samaj, developed during this time and counted many of the leaders of the Bengal Renaissance among its followers. In the earlier years the Brahmo Samaj, like the rest of society, could not however, conceptualize, in that feudal-colonial era, a free India as it was influenced by the European Enlightenment (and its bearers in India, the British Raj) although it traced its intellectual roots to the Upanishads. Their version of Hinduism, or rather Universal Religion, although devoid of practices like sati and polygamy that had crept into the social aspects of Hindu life, was ultimately a rigid impersonal monotheistic faith, which actually was quite distinct from the pluralistic and multifaceted nature of the way the Hindu religion was practiced. Leader Keshub Chunder Sen was devotee of Brahma, Krishna, Buddha and Christ. It has been argued by some scholars that the Brahmo Samaj movement, in spite of its universality, never gained the support of the masses and remained restricted to the elite, although Hindu society has accepted most of the social reform programmes of the Brahmo Samaj. It must also be acknowledged that many of the later Brahmos were also among the leaders of the freedom movement.
The renaissance period after the Indian Rebellion of 1857 saw a magnificent outburst of Bengali literature. While Ram Mohan Roy and Iswar Chandra Vidyasagar were the pioneers, others like Bankim Chandra Chatterjee widened it and built upon it. The first significant nationalist detour to the Bengal Renaissance was given by the brilliant writings of Bankim Chandra Chatterjee. Later writers of the period who introduced broad discussion of social problems and more colloquial forms of Bengali into mainstream literature included the great Saratchandra Chatterjee.
The Tagore family, including Rabindranath Tagore, were leaders of this period and had a particular interest in educational reform. Their contribution to the Bengal Renaissance was multi-faceted. Indeed, Tagore's 1901 Bengalinovella, Nastanirh was written as a critique of men who professed to follow the ideals of the Renaissance, but failed to do so within their own families. In many ways Rabindranath Tagore's writings (especially poems and songs) can be seen as imbued with the spirit of the Upanishads. His works repeatedly allude to Upanishadic ideas regarding soul, liberation, transmigration and—perhaps most essentially—about a spirit that imbues all creation not unlike the Upanishadic 'Brahman'. Tagore's English translation of a set of poems titled the Gitanjali won him the Nobel Prize for Literature in 1913. He was the first Asian to win this award. That was the only example at the time but the contribution of the Tagore family was enormous.
Upendranath Brahmachari was a noted Indian scientist and a leading medical practitioner of his time. He synthesized Urea Stibamine (carbostibamide) in 1922 and determined that it was an effective substitute for the other antimony-containing compounds in the treatment of Kala-azar (Visceral leishmaniasis) which is caused by a protozoon, Leishmania donovani. Brahmachari was a nominee for the Nobel Prize in 1929 in the category of physiology and medicine. He was president of the 23rd session of the Indian Science Congress in Indore (1936) as well as the president of the Indian Chemical Society, Calcutta (1936).
The conquest of Bengal by the English was not only a political revolution, but ushered in a greater revolution in thoughts and ideas, in religion and society... From the stories of gods and goddesses, kings and queens, princes and princesses, we have learnt to descend to the humble walks of life, to sympathise with the common citizen or even common peasant … Every revolution is attended with vigour, and the present one is no exception to the rule. Nowhere in the annals of Bengali literature are so many and so bright names found crowded together in the limited space of one century as those of Ram Mohan Roy, Akshay Kumar Datta, Ishwar Chandra Vidyasagar, Michael Madhusudan Dutt, Sharat Chandra Chatterji, Bankim Chandra Chatterjee and Dina Bandhu Mitra. Within the three quarters of the present century, prose, blank verse, historical fiction and drama have been introduced for the first time in the Bengali literature...
