Born into a Bengali Muslim Kazi family hailing from Burdwan district in Bengal Presidency (now in West Bengal, India),[2] Nazrul Islam received religious education and as a young man worked as a muezzin at a local mosque. He learned about poetry, drama, and literature while working with the rural theatrical group Leṭor Dôl, Leṭo being a folk song genre of West Bengal[13] usually performed by the people from Muslim community of the region. He joined the British Indian Army in 1917 and was posted in Karachi. Nazrul Islam established himself as a journalist in Calcutta after the war ended. He criticized the British Raj and called for revolution through his famous poetic works, such as "Bidrohī" ('The Rebel') and "Bhangar Gan" ('The Song of Destruction'),[14] as well as in his publication Dhūmketu ('The Comet'). His nationalist activism in Indian independence movement led to his frequent imprisonment by the colonial British authorities. While in prison, Nazrul Islam wrote the "Rajbôndīr Jôbanbôndī" ('Deposition of a Political Prisoner').[15] His writings greatly inspired Bengalis of East Pakistan during the Bangladesh Liberation War.
