Public DomainRabindranath Tagore
Rabindranath Tagore was a widely regarded Indian literary figure, popular poet, novelist, musician, and playwright who reshaped Bengali literature and music in the late 19th and early 20th centuries. His first poetry was written at age eight and by 16 he had published works under the pseudonym Bhanushingho (Sun Lion).

Tagore was famous for denouncing the British Raj and supporting Indian independence. He was knighted by the British Crown in 1915 but later returned this knighthood in protest of the Jallianwala Bagh massacre in 1919.
