♦ India–Bangladesh Relations ♦

India and Bangladesh share one of the most important bilateral partnerships in South Asia, rooted in shared history, geography, culture, and economic interdependence. Their relationship is unique because it was shaped not only by political diplomacy but also by emotional, cultural, and historical connections. The foundation of modern ties was laid during the Bangladesh Liberation War in 1971, when India played a decisive role in helping Bangladesh achieve independence. Since then, cooperation has expanded across trade, connectivity, defence, energy, and regional stability.

The importance of this partnership goes beyond the two countries. It influences regional security, connectivity to Southeast Asia, and geopolitical competition in the Bay of Bengal region. With a long land border, shared rivers, and deep people-to-people links, both countries depend on each other for economic growth and security.

Historical Background and Foundation of Modern Relations

The roots of the relationship go back centuries when present-day Bangladesh was part of the Bengal region under British rule. During the colonial period, Bengal was one of the most important administrative, cultural, and economic centers of British India. People on both sides shared language, traditions, and economic activities, which created a strong social foundation that continues today.

After the partition of India in 1947, East Bengal became East Pakistan, even though it was separated from West Pakistan by around 1,600 km of Indian territory. This geographical separation led to political and economic neglect. Dissatisfaction grew among the people of East Pakistan, eventually leading to a liberation movement.

The most important turning point came during the 1971 Liberation War. Pakistan launched Operation Searchlight in March 1971 to suppress the independence movement, resulting in widespread violence. Around 10 million refugees fled to India, creating a humanitarian crisis. India, led by Prime Minister Indira Gandhi, supported the independence movement and intervened militarily in December 1971.

Bangladesh became independent on 16 December 1971 under the leadership of Sheikh Mujibur Rahman, and India became the first country to recognize the new nation.
