Serajul Alam Khan

Nizam Mohammad Serajul Alam Khan (6 January 1941 – 9 June 2023), commonly known as Serajul Alam Khan (Bengali: সিরাজুল আলম খান), also called as Dada, Dadabhai and by his initials SAK, was a Bangladeshi politician, political analyst, philosopher and writer who spearheaded the Bangladesh liberation movement under the leadership of Sheikh Mujibur Rahman but also became one of the controlling forces of political polarization in post-independence Bangladesh.

Serajul Alam Khan joined politics in the 1950s–60s as a student and quickly rose to the helm of Chhatra League, the student wing of the Bengali nationalist Awami League in Pakistan. He, along with others, founded the Swadhin Bangla Biplobi Parishad (which came to be known as 'Nucleus'), a secret organization whose existence is not directly documented but strongly supported by popular hearsay and conventional history. The organization played a significant role in the Bangladesh Liberation War.^[1] He along with Tofael Ahmed, Sheikh Fazlul Haque Moni and Abdur Razzaq formed and commanded the Mujib Bahini (a.k.a. Bangladesh Liberation Force).^[2]
