During the first half of the 20th century, the Indian Independence Movement began to reach its peak and took a violent turn in Bengal. On the eighth of December 1930, three revolutionaries, Benoy, Badal and Dinesh, stormed the building and fatally shot the Inspector General of Prisons, N.S. Simpson. The three committed suicide and the square was renamed B.B.D. Bagh in their honor after Indian independence. In 1947, the political establishments were officially handed over to the government of India and the government of the newly formed state of West Bengal. Over the next few decades, Kolkata (formerly called Calcutta) would go through rapid economic decline, but B.B.D. Bagh would remain the heart of East India.
