The Swadhin Bangla Biplobi Parishad (English: Independent Bangla Revolutionary Council) was an armed underground student political group secretly organized in 1961 by Serajul Alam Khan, a key founder of Bangladesh, that worked to wage an armed secessionist struggle against Pakistani rule and achieve the independence of East Pakistan as "Bangladesh".
The students of this league were recruited into the Mukti Bahini (Liberation Army), Sheikh Mujibur Rahman's armed guerrilla force and the military arm of his political party the Bangladesh Awami League trained by India's foreign intelligence organization the Research and Analysis Wing[2][3] to wage the liberation struggle.
The general strike, pogroms and the resulting war followed on the heels of the Agartala Conspiracy, at the time deemed a politically motivated accusation by the Pakistani state against Bengali leaders but confirmed in 2011 to be factually true by the Bangladeshi Parliament's Deputy Speaker and one of the Agartala conspirators Shawkat Ali.
[8] By the start of the war, other countries hostile to Pakistan seized upon the opportunity and gave material assistance to this student movement (that had by now morphed into an armed guerrilla revolt) to bring about Pakistan's disintegration, with a potentially friendly nation's independence being a favorable by-product.
[13] The central role of students in the armed secessionist rebellion aided by India[14][15] was the main reason why the Razakars killed Bengali students and intellectuals on Dhaka University grounds on 25 March at the start of Operation Searchlight and committed another massacre of Bengali intellectuals on 14 December, two days before Pakistan's defeat and surrender and Bangladesh's resulting independence.
