Kazi Nazrul Islam (Bengali: কককক ককককক ককককক, pronounced [kazi nozrul islam]) (24 May 1899 – 29 August 1976) was a Bengali poet, writer, musician, and revolutionary. He is the national poet of Bangladesh.[2] Popularly known as Nazrul, he produced a large body of poetry and music with themes that included religious devotion and spiritual rebellion against fascism and oppression.[3] Nazrul's activism for political and social justice earned him the title of "Rebel Poet" (Bengali: কককককককক ককক; Bidrohi Kobi).[4] His compositions form the avant-garde genre of Nazrul Sangeet (Music of Nazrul). Nazrul and his works are equally commemorated and celebrated in Bangladesh and India, particularly in India's Bengali-speaking states such as West Bengal, and Tripura.
