1971 War Between Pakistan and Bangladesh Explained

The 1971 War between Pakistan and Bangladesh was one of the most defining moments in South Asian history. It not only led to the creation of a new nation, Bangladesh, but also reshaped the geopolitics of the region. This war was short but brutal, lasting only 13 days, yet its impact continues to influence Pakistan–Bangladesh relations even in 2025.

In this post, we’ll explain the 1971 war, its causes, events, consequences, and legacy—helping you understand why it was more than just a battle, but a struggle for identity and independence.

Background: East vs. West Pakistan

After the Partition of India in 1947, Pakistan was created with two wings:

• West Pakistan (modern-day Pakistan)
• East Pakistan (modern-day Bangladesh)

Although united under the idea of Islam, the two wings were separated by over 1,600 kilometers of Indian territory and had deep cultural, linguistic, and economic differences.

Causes of the 1971 War

1. Language Dispute – Bengalis demanded Bengali be recognized as a state language, but West Pakistan pushed for Urdu.
2. Economic Inequality – East Pakistan contributed the majority of export revenue (like jute), yet received far less investment.
3. Political Marginalization – Despite having more population, East Pakistan had less political power.
4. 1970 General Elections – Sheikh Mujibur Rahman’s Awami League won a majority, but West Pakistan’s military and political elite refused to hand over power.

Key Events of the 1971 War

• March 7, 1971 – Sheikh Mujibur Rahman gave his historic speech demanding autonomy.
• March 25, 1971 (Operation Searchlight) – Pakistan Army launched a brutal crackdown in Dhaka, targeting students, activists, and civilians.

• India’s Involvement – After months of tensions, India officially joined the war on December 3, 1971, supporting Bangladesh’s Mukti Bahini fighters.
