Historical Context and Chronology- March 1971

In early March 1971, Bangladesh (then East Pakistan) was gripped by crisis. After the Awami League’s landslide election victory in December 1970, West Pakistan’s government refused to hand over power. Mass protests and a non-cooperation movement followed. On 25 March 1971, the Pakistani Army launched Operation Searchlight – a massive crackdown in Dhaka and across East Pakistan.[1][2]. By late 25 March, Sheikh Mujibur Rahman (the Awami League leader) and many colleagues realized that negotiations had failed and that Pakistan planned martial law. That night, before his arrest by the Pakistani military, Sheikh Mujibur Rahman issued orders for resistance and declared Bangladesh’s independence. According to contemporary records, at about midnight (25–26 March) Sheikh Mujib “sent a message… proclaiming the independence of Bangladesh”[3]. Major international newspapers (e.g. Times of London March 27) reported a clandestine radio broadcast stating “the Sheik has declared the 75 million people of East Pakistan as citizens of the sovereign independent Bangla Desh.”[2]. These accounts confirm that by 26 March the declaration of independence had been made and was known via underground radio.

Declaration of Independence 1971 – Broadcasts and Texts

Sheikh Mujibur Rahman’s Message (26 March 1971): Sheikh Mujib’s final directives were sent out just before his arrest on 25 March. In one famous version (cited by historians and in Bangladesh’s official narrative), Mujib said:

“This may be my last message. From today Bangladesh is independent. I call upon the people of Bangladesh wherever you might be…and with whatever you have, to resist the army of occupation to the last. Your fight must go on until the last soldier of the Pakistan occupation army is expelled… Final victory is achieved.”[4].

This message was reportedly recorded on radio late on 25 March (or early 26th) and aimed at foreign media listening to Radio Pakistan Dacca[5][4]. It marked the formal declaration of independence by Bangabandhu. (Different versions of the text exist, but all convey that Bangladesh is independent from this day.)

Hannan’s Broadcast (26 March 1971): On the afternoon of 26 March, Awami League leaders in Chittagong publicly announced the declaration. Documents of the Liberation War (and later press) record that M.A. Hannan, General Secretary of Chittagong District Awami League, read Bangabandhu’s proclamation to a crowd:

“Today Bangladesh is a sovereign and independent country. On Thursday night [March 25, 1971]… West Pakistan armed forces attacked… Dhaka… Innocent and unarmed have been killed… The Bangalees are fighting the enemy with great courage for an independent Bangladesh. … May Allah aid us in our fight for freedom. Joy Bangla,” – read by M.A. Hannan on behalf of Bangabandhu[6].

This text (carried widely in newspapers) is identical to the declaration noted above. Records from the underground Swadhin Bangla Betar Kendra radio confirm that a special announcement was broadcast on 26 March, announcing “Shortly, M.A. Hannan… will read Bangabandhu Sheikh Mujibur Rahman’s declaration of independence on behalf of the nation. M.A. Hannan then read the proclamation.”[7]. In sum, Mujib’s declaration (from Dhaka via radio or telegram) was publicly proclaimed by AL leaders in Chittagong on 26 March.

Major Ziaur Rahman’s Broadcasts (27–28 March 1971): Major Ziaur Rahman (then an army officer in Chittagong) also made a famous proclamation, but its timing and context differed. On 27 March 1971 at 7:45 pm (Kalurghat radio), Zia announced on behalf of Sheikh Mujib:

“This is Swadhin Bangla Betar Kendra. I, Major Ziaur Rahman, at the directive of Bangabandhu Sheikh Mujibur Rahman, hereby declare that the independent People’s Republic of Bangladesh has been established… By the grace of Allah, victory will be ours. Joy Bangla.”[8][9].

This speech was explicitly “on behalf of Bangabandhu” and closely followed the text already given by Mujib. Historical research confirms that Zia was reading the same declaration prepared by others (Awami League leaders)[10][11]. In fact, detailed histories show Zia first broadcast Mujib’s declaration on 27 March and repeated it again on 28 March to “end confusion”[11][12]. (On 28 March, Zia did momentarily declare himself “Acting Head of State,” causing consternation, but he later retracted that and merely restated Mujib’s message[13][12].)

Importantly, every one of these announcements traces back to Mujibur Rahman’s original declaration. Even Western news coverage noted that Zia’s broadcast was “on behalf of Mujib” and that Mujib himself had declared independence earlier[8][2]. And as one timeline of the war states, Zia’s speech “was more to the credit of an ex-officio army official than… Mujib” – it was simply the same proclamation recited[14].

Official Endorsement and Legal Proclamation (April 1971)

The Provisional Government of Bangladesh (formed in exile at Mujibnagar) formally ratified Bangabandhu’s declaration on 10 April 1971. The April 10 Proclamation of Independence (drafted by legal experts) explicitly recognized Mujib’s role:

“Bangabandhu Sheikh Mujibur Rahman… made a declaration of independence at Dacca on 26 March 1971, and urged the people of Bangladesh to defend the honour and integrity of Bangladesh… We the elected representatives… do hereby… confirm the declaration of independence already made by Bangabandhu Sheikh Mujibur Rahman… and do hereby affirm… that this proclamation of independence shall be deemed to have come into effect from 26th day of March 1971.”[15].

In other words, the first legal document of independent Bangladesh (April 1971) treats 26 March 1971 as the effective date of independence and attributes the proclamation to Sheikh Mujibur Rahman[15]. This official act settled the date in law and endorses the account that Mujib’s message (issued late 25th/early 26th) was the true declaration.

Controversies and Alternate Claims

Despite this record, major controversies have persisted in Bangladesh’s historiography and politics. In later years, some political factions (notably those aligned with Ziaur Rahman) have claimed that Zia, not Mujib, was the “real proclaimer” of independence[16][10]. These claims focus on Zia’s radio announcements on March 27–28 and suggest they constituted the founding proclamation. However, most historians and contemporaneous sources refute that interpretation. They note that Zia’s role was explicitly in support of Bangabandhu’s leadership: his broadcasts used Mujib’s name and read a declaration drafted by Mujib’s circle[8][11]. In fact, Awami League analyses stress that Zia’s speeches merely repeated Mujib’s words and were not independent proclamations[10][11].

Indeed, modern research on the Kalurghat radio records shows that M.A. Hannan’s 26 March broadcast (under Mujib’s authority) predated Zia’s speech, and that Zia’s initial announcement on 27 March simply relayed the already-issued declaration[7][11]. Zia himself never claimed credit for making an original declaration during his lifetime. His 1972 writings even portray Mujib’s 7 March speech as the signal for independence struggle[17]. (Zia’s later supporters, after 1975, promoted a rival narrative – for example, revising textbooks – but these innovations were politically driven and not supported by wartime evidence.)

Thus, while political debate has framed this as a dichotomy (“Mujib vs Zia proclaimed independence”), the historical record indicates a single lineage of proclamation: Sheikh Mujibur Rahman’s leadership and speeches were the source[15][2], with Zia’s role limited to broadcasting that same declaration for the liberation fighters.

Evidence from Primary Sources

Radio Transcripts & Witnesses: Archives of Swadhin Bangla Betar Kendra (the rebel radio) record sessions on 26–28 March 1971 where Mujib’s message was played and announced[7][11]. These show Awami League leaders and later Major Zia reading the declaration.
News Reports: Immediately after the events, foreign press picked up the declaration. For instance, The Times (London, 27 Mar 1971) reported that a secret radio said “Sheik Mujibur Rahman declared independence for East Pakistan”[2]. The Los Angeles Times (27 Mar) similarly headlined “Sheik Mujibur Rahman declared independence… East Pakistan civil war”[2]. These articles make no mention of Zia, confirming the global perception that Mujib’s move was key.
Government Documents: The April 1971 Proclamation (cited above) is a primary legal document ratifying the independence on Mujib’s authority[15]. Bangladesh’s Constitution and official histories have maintained 26 March as Independence Day since 1972.
Interviews and Memoirs: In later years, veterans like Brigadier A.K. Khandker noted that Mujib avoided broadcasting so as not to provide treason evidence[18], but they agree he sent a final message. Scholars like Muntassir Mamoon and Sarmila Bose (and works like Tajuddin’s papers) all credit Mujib’s 26 March role and place Zia’s speech in that context.

Historians’ Analysis

Contemporary historians largely concur that Sheikh Mujibur Rahman is the sole true “proclaimer of independence,” with March 26 as the de facto declaration date. As one reviewer puts it, “Bangabandhu (Mujib) in his late-night 25–26 March statements formally declared independence” and other attempts (by Bhashani, Zia, etc.) “did not go down in the annals of Bangladesh’s independence history”[19]. While acknowledging that Ziaur Rahman’s broadcasts boosted morale, analysts emphasize that those talks were “simply reading out a drafted statement” prepared for Mujib[20][11].

No credible historian argues that Bangladesh became independent on any date other than 26 March 1971. The post-war interim government and the 1972 Constitution explicitly set 26 March as the symbolic birth of the nation[15][21]. Modern research (including declassified archives and oral histories) has found no evidence of any earlier or alternative declaration date. The narrative that “Zia proclaimed independence on 27th” is generally viewed as a later political construction rather than historical fact.

Conclusion

In sum, the established historical account is that on 26 March 1971 Bangladesh’s independence was formally proclaimed by Sheikh Mujibur Rahman (the undisputed leader of the Bengali nation) through radio and direct messages to his people[2][4]. His declaration – delivered just before he was arrested – is enshrined in the legal Proclamation of April 1971 as the founding act of independence[15]. Major Ziaur Rahman’s role was to relay that declaration on 27–28 March and to rally the resistance; his broadcasts explicitly cited Mujib as the author of the declaration[8][11]. Although politics has generated disputes (with some later claims crediting Zia), primary sources and scholarly analysis make clear that Bangabandhu Sheikh Mujibur Rahman’s 26 March announcement is the factual basis of Bangladesh’s Independence Day, and this is the version upheld by historical evidence[6][15].

Sources: Historical timelines, government archives, newspapers of 1971, and scholarly histories[2][8][6][15] provide a consistent picture of the events and help settle the disputes. Each viewpoint has been examined against primary documents and neutral accounts to arrive at the above conclusions.
