The Bengali Renaissance refers to a social reform movement during the nineteenth and early twentieth centuries in the Bengal region of India during the period of British rule dominated by English educated Bengali Hindus. The Bengal Renaissance can be said to have started with Raja Ram Mohan Roy (1772–1833) and ended with Rabindranath Tagore (1861–1941), although many stalwarts thereafter continued to embody particular aspects of the unique intellectual and creative output of the region. Nineteenth century Bengal was a unique blend of religious and social reformers, scholars, literary giants, journalists, patriotic orators, and scientists, all merging to form the image of a renaissance, and marked the transition from the 'medieval' to the 'modern'.
