1. Background — The Road to 1971
Political Tensions (1947–1970)
After the partition of British India in 1947, East Pakistan and West Pakistan were created. From the very beginning, East Pakistan (majority Bengali-speaking) felt discriminated against by West Pakistan:
- Language: Urdu was declared the only official language of Pakistan, ignoring the Bengali majority
- The Language Movement (1952): Students protested; police fired on protesters on 21 February 1952 (see GK-005)
- Six-Point Demand (1966): Sheikh Mujibur Rahman presented the Six-Point Programme, demanding autonomy for East Pakistan
- Agartala Conspiracy Case (1969): Sheikh Mujibur Rahman and 34 others were tried for alleged conspiracy to divide Pakistan; mass protests led to the case being dropped
- 1969 Student Movement: Massive uprising led to the fall of Ayub Khan; Yahya Khan became President
The 1970 Elections
In the 1970 general elections, Sheikh Mujibur Rahman’s Awami League won a landslide:
- Awami League: 167 seats (East Pakistan)
- Pakistan People’s Party (Zulfikar Ali Bhutto): 88 seats (West Pakistan)
Despite this clear mandate, the West Pakistani establishment refused to transfer power. This sparked the mass movement that led to the Liberation War.
2. March 1971 — The War Begins
The Crisis Deepens (1–24 March)
On 1 March 1971, President Yahya Khan postponed the National Assembly session indefinitely — the trigger for mass unrest. On 7 March 1971, Sheikh Mujibur Rahman delivered his historic speech (see GK-005), calling for non-cooperation and effectively launching the independence movement. Between 7 March and 25 March, the de facto governance of East Pakistan was in Sheikh Mujibur Rahman’s hands.
Operation Searchlight (25–26 March 1971)
On the night of 25 March 1971, the Pakistani army launched Operation Searchlight — a systematic military crackdown on East Pakistan:
- The army targeted Dhaka University, the Dhaka Radio Station (Betar), and the homes of Awami League leaders
- Thousands of civilians, students, and intellectuals were killed
- Sheikh Mujibur Rahman was arrested at his home and flown to West Pakistan (then imprisoned in Mianwali Jail)
- The killings triggered a mass exodus of refugees to India
The Proclamation of Independence (26 March 1971)
Before his arrest, Sheikh Mujibur Rahman issued the Proclamation of Independence of Bangladesh. He declared East Pakistan an independent nation. The formal announcement was made by the Awami League leadership from the Gonobhaban (the Presidential residence) before Sheikh Mujibur Rahman was taken away.
3. The Mujibnagar Government (April 1971)
On 10 April 1971, the Mujibnagar Government was established as the provisional government of Bangladesh at a border town in Meherpur district (Baidayanathtola):
Key Appointments:
- President: Sheikh Mujibur Rahman (imprisoned in Pakistan; represented symbolically)
- Vice President: Syed Nazrul Islam
- Prime Minister: Tajuddin Ahmad
- Commander-in-Chief: General M. A. G. Osmani
- Foreign Minister: Khondaker Mostaq Ahmad
On 17 April 1971, the Constitution of Bangladesh was adopted by the Mujibnagar Government, formally establishing the state.
The Cabinet: Tajuddin Ahmad’s cabinet included key ministers who organized the war effort, diplomacy, and civil administration from exile in India.
4. The Mukti Bahini — Freedom Fighters
The Bangladesh Forces, popularly known as the Mukti Bahini (Freedom Fighters), were the armed resistance forces.
Formation and Structure
The Mukti Bahini was formed from:
- Bengali members of the Pakistan army who defected to Bangladesh’s side
- Civilian volunteers and guerrilla fighters
- Members of the East Pakistan Rifles (EPR) who mutinied
Key Commanders and Units
General M. A. G. Osmani (1918–2020): The Commander-in-Chief of the Bangladesh Forces. A veteran of the British Indian Army, he organized the Mukti Bahini into an effective guerrilla force. He was known as “Tiger of the Liberation War” and is a national hero.
Ziaur Rahman (1936–1981): Commander of Z-Force (also called the “Z” Force or “Zia Force”), one of the most effective Mukti Bahini units. Zia later became President of Bangladesh (1977–1981). He was instrumental in several key battles along the Meghna River corridor.
M. A. Hannan: A celebrated Sector Commander who led guerrilla operations in the Chittagong region. He was known for bold attacks on Pakistani positions.
Kazi Mohammad Esa: A sector commander known for organizing the guerrilla campaign in the northern districts.
The 11 Sectors
The Mukti Bahini organized the liberation struggle into 11 sectors, each commanded by a sector commander. Inter-sector coordination was managed by General Osmani from the Combined Headquarters in Calcutta (India).
Guerrilla Tactics
Mukti Bahini fighters used guerrilla warfare effectively:
- Ambushes on Pakistani army convoys
- Sabotage of railways, bridges, and communication lines
- Intelligence gathering
- Riverine operations using small boats
5. Key Battles and Events of the War
The Battle of Gazipur (March 1971)
One of the first major engagements where Mukti Bahini fighters ambushed Pakistani troops.
The Battle of Belonia (April 1971)
A significant victory for the Mukti Bahini in the Chittagong Hill Tracts region, where local forces repelled a Pakistani attack.
The Battle of Boyra (November 1971)
In November 1971, Mukti Bahini forces crossed into East Pakistan in force, beginning the final phase of the war. The Battle of Boyra near the border town of Boyra saw Mukti Bahini fighters defeat Pakistani forces and capture significant territory.
The Jessore Battle (March–April 1971)
The Battle of Jessore was a major defensive engagement where Mukti Bahini and supporting Indian forces defended against Pakistani advances.
The Bogra Battle
Mukti Bahini forces in the Bogra region conducted effective guerrilla operations, disrupting Pakistani supply lines.
6. India’s Role and the Indo-Bangladesh Victory
India’s Military Intervention
As the war progressed, India provided increasing support to Bangladesh:
- ** Sanctuary and training:** India provided refuge and military training to Mukti Bahini fighters
- Humanitarian aid: India provided food, shelter, and medical care to millions of refugees
- Logistical support: India shared intelligence and provided a staging ground for operations
On 28 November 1971, India formally entered the war, launching a full-scale military operation alongside the Mukti Bahini. The Indian Army’s Eastern Command led by General Jagjit Singh Arora coordinated the joint operations.
The Final Offensive (December 1971)
In the first two weeks of December 1971, the joint Bangladeshi-Indian forces advanced rapidly:
- Eastern Command advanced from the west and north
- Mukti Bahini forces advanced from multiple sectors
- The Pakistani army was encircled in Dhaka
The Surrender — 16 December 1971
On 16 December 1971, Pakistan’s Eastern Command formally surrendered to the joint forces:
- General A. A. K. Niazi (Pakistan’s Eastern Commander) signed the Instrument of Surrender
- General M. A. G. Osmani (Bangladesh) and General Jagjit Singh Arora (India) accepted the surrender
- The surrender ceremony was held at the Ramna Race Course (now Suhrawardy Udyan) in Dhaka
This was exactly 9 months and 20 days after the declaration of independence on 26 March 1971.
7. International Dimension
Soviet Union and the UN
The Soviet Union supported Bangladesh and India during the war. It vetoed a US-proposed ceasefire resolution in the UN Security Council in December 1971, arguing that Pakistan’s actions were an internal matter. This was a critical diplomatic victory for Bangladesh.
United States
The Nixon administration in the US supported Pakistan, which created lasting resentment in Bangladesh. The US considered Pakistan a Cold War ally. However, after Bangladesh’s independence, the US recognized the new nation and established diplomatic relations.

The Intellectuals’ Killing (14 December 1971)
On the night of 14 December 1971, just two days before the surrender, the Pakistani army and their collaborators systematically killed leading Bangladeshi intellectuals — professors, writers, journalists, doctors, and artists. This is known as the Ekushey Khoon (Massacre of 1971). Among those killed were:
- Satyendra Prasad Mazumdar (economist)
- M. A. Gafur (artist)

This event is commemorated on 14 December as Martyred Intellectuals Day (শহীদ বুদ্ধিজীবী দিবস).
The War of Independence in Global Context
Bangladesh’s Liberation War was one of the most significant decolonization struggles of the 20th century. It demonstrated that a small, determined population could defeat a larger professional army — even with outside support — through guerrilla warfare and political mobilization.
