During the Bangladesh Liberation War, he was declared as the Vice President of Bangladesh by the Provisional Government. He served as the Acting President in the absence of Sheikh Mujibur Rahman.^[1]

Syed Nazrul Islam was born in 1925, into a Bengali Muslim family of Syeds in the village of Bir Dampara, Jashodal Union in Kishoreganj (then Mymensingh District) of the Bengal Presidency.^[2] He obtained degrees in history and law from the University of Dhaka and was an active student political leader in the Muslim League.

He entered the civil service of Pakistan in 1949 but resigned in 1951 to work as a professor of history at the Anandmohan College in Mymensingh, where he also practised law.^[3]

Nazrul Islam's political career began when he joined the Awami Muslim League and participated in the Language Movement in 1952, for which he was arrested by Pakistani police. He would rise to various provincial and central party leadership positions, becoming a close confidante of the party's leader Sheikh Mujib. He was jailed during the Six Point Demand movement.^[4] He was elected to the National Assembly of Pakistan in 1970, where he served briefly as deputy leader of the majority. Following the arrest of Mujib on 25 March 1971 by Pakistani forces, Syed escaped to Mujibnagar with other party leaders and proclaimed the independence of Bangladesh.^[5] Mujib was elected president of Bangladesh but Syed would serve as acting president, with Tajuddin Ahmed as prime minister. Syed played a key role in leading the nationalist cause, co-ordinating the Mukti Bahini guerrilla force and winning support from India and other nations.^[3]

After the independence of Bangladesh, Syed was appointed minister of industries, the deputy leader in parliament and a member of the constitution committee. When Mujib banned other political parties and assumed sweeping powers as president in 1975, Syed was appointed vice-chairman of the BAKSAL, the renamed Awami League.^[3]
