India and Bangladesh share deep bonds rooted in history, language, culture, and various commonalities. Their partnership has evolved as a model for bilateral relations, marked by sovereignty, equality, trust, and understanding, and extends far beyond a strategic alliance.

Historical Ties
- India played a pivotal role in the 1971 Bangladesh Liberation War by providing crucial military and material support.
- Bilateral relations strained in the mid-1970s due to military regimes in Bangladesh, which fuelled anti-India sentiment over issues like boundary disputes and water-sharing disputes.
- A positive shift occurred in 1996 when Sheikh Hasina came to power, leading to strengthened ties with the signing of the Ganga Waters Treaty.
- Over the years, the partnership has grown, encompassing key areas such as trade, energy, infrastructure, connectivity, and defence.
