Introduction

Pakistan came into existence on 14 August 1947 as a homeland for the Muslims of the subcontinent. It consisted of two geographically separate wings: East Pakistan and West Pakistan, divided by approximately 1,600 kilometres of Indian territory. Although both wings were part of one country, they differed in language, culture and social traditions.

From the early years of independence, disagreements developed over political representation, administrative authority, recruitment into the armed forces and the distribution of economic resources. Many people in East Pakistan believed that the central government, dominated largely by political and military leaders from West Pakistan, did not adequately represent their interests. These grievances gradually increased mistrust between the two wings and strengthened demands for provincial autonomy.

Major Reasons for Tension Between East and West Pakistan

1. Unfairness in Administration and Lack of Political Representation

Although East Pakistan had a larger population than West Pakistan, its population majority was not consistently reflected in political power and decision-making. The central government and important administrative institutions remained heavily influenced by leaders from West Pakistan.

The dissolution of the Constituent Assembly in 1954 and the introduction of the One Unit scheme in 1955 further contributed to political dissatisfaction in East Pakistan. The One Unit scheme combined the provinces of West Pakistan into one administrative unit, helping maintain parity between the two wings despite their different populations.

Many Bengalis believed that important national policies were formulated without adequate consideration of East Pakistan’s needs. The concentration of authority in the central government limited the provinces’ ability to manage their own affairs.

Impact: These political and administrative inequalities created resentment in East Pakistan and increased demands for democratic representation, provincial autonomy and a fairer distribution of political power.

2. Lack of Representation in the Armed Forces

After independence, Bengalis were significantly underrepresented in Pakistan’s armed forces, particularly in the army and senior military positions. Recruitment patterns inherited from British colonial rule favoured certain communities of West Pakistan, especially Punjabis. As a result, the military leadership and command structure remained heavily concentrated in the western wing.

East Pakistan also felt vulnerable because the main military establishments and much of the country’s defence infrastructure were located in West Pakistan. During the 1965 war with India, East Pakistan was left with limited military protection, increasing concerns about its security.

The lack of representation in the armed forces meant that East Pakistan had limited influence in one of the country’s most powerful institutions.

Impact: Underrepresentation in the military increased feelings of insecurity and political exclusion among Bengalis. It strengthened demands for a fair share in military recruitment, senior appointments and national defence decision-making.

3. Unequal Economic Distribution

Economic inequality was one of the major causes of tension between East and West Pakistan. East Pakistan produced valuable export commodities, particularly raw jute, which earned substantial foreign exchange for the country. However, many people in East Pakistan believed that the region did not receive a fair share of the resources generated by its economic activities.

A large proportion of public investment, industrial development and infrastructure spending went to West Pakistan. Industrialists and businesses in the western wing benefited from government policies, while East Pakistan remained comparatively less developed in several important sectors.

The income gap between the two wings also widened during the 1960s. According to a contemporary analysis published in 1971, average per capita income in West Pakistan was approximately 32% higher than in East Pakistan in 1959–60; by 1969–70, the difference had increased to approximately 61%.

East Pakistan’s grievances included:

Unequal development expenditure: East Pakistan’s share of central development spending was considered inadequate in relation to its population and economic contribution. Limited industrial investment: West Pakistan received a greater share of industrial investment and benefited from the expansion of major industries. Unequal access to economic opportunities: Many Bengalis believed that employment, investment and business opportunities favoured influential groups in West Pakistan. Income disparity: The widening difference in per capita income increased the perception that economic development was benefiting the western wing disproportionately.

Impact: Economic inequality increased resentment towards the central government. It strengthened the belief that East Pakistan’s resources were being used without an equivalent return in development and public welfare. Economic grievances consequently became an important part of the demand for provincial autonomy.

4. The Language Issue and Cultural Differences

Language and cultural identity also contributed to tensions between the two wings. After independence, the central government sought to establish Urdu as the sole national language, although Bengali was spoken by the majority of Pakistan’s population.

Many Bengalis demanded that Bengali should also receive national-language status. They viewed the recognition of their language as essential for protecting their cultural identity and ensuring equal treatment in education, administration and public life.

On 21 February 1952, police opened fire on students protesting for the recognition of Bengali in Dhaka. Several people were killed, and the incident became a defining event in the Bengali Language Movement. Bengali was eventually recognised as one of Pakistan’s state languages under the 1956 Constitution.

Impact: The language controversy deepened mistrust between East and West Pakistan. It strengthened Bengali cultural and political consciousness and contributed to the wider demand for equal rights and provincial autonomy.

5. Political Disagreements and the Demand for Provincial Autonomy

The concentration of power in the central government created continuing disagreements between East and West Pakistan. Many Bengalis believed that the central authorities did not adequately respect their electoral strength or allow them sufficient control over provincial affairs.

In 1966, Sheikh Mujibur Rahman presented the Six-Point Programme, which demanded extensive provincial autonomy, including greater control over taxation, foreign exchange earnings and economic affairs. The programme gained considerable support in East Pakistan because it addressed political and economic grievances.

The issue became more serious after the general elections of December 1970. The Awami League won 160 of East Pakistan’s 162 general National Assembly seats and secured an overall majority in the Assembly. However, disagreements over constitution-making and the transfer of power prevented a peaceful political settlement.

Impact: The failure to reach an agreement deepened the political divide and weakened the possibility of maintaining a united Pakistan through a mutually accepted constitutional arrangement.

Reasons at a Glance

Conclusion

Tensions between East and West Pakistan developed over many years because of political, administrative, military, economic and cultural differences. East Pakistan’s larger population was not consistently reflected in political power, Bengalis were underrepresented in the armed forces, and economic development remained uneven between the two wings. The language controversy further increased mistrust and strengthened Bengali political identity.

These grievances encouraged demands for provincial autonomy and greater democratic representation. The failure to resolve them, particularly after the 1970 general elections, contributed to the crisis of 1971 and the separation of East Pakistan, which became Bangladesh.
