Nepal’s Uncertainty Over 1816 Sugauli Treaty Rekindles India Border Debate

Nepal’s inability to confirm the whereabouts of the original signed copy of the 1816 Sugauli Treaty has brought fresh attention to its long-standing boundary disagreements with India.

Foreign Minister Shisir Khanal told Nepal’s House of Representatives that the government does not have clear information establishing whether the original treaty is currently held in the country’s archives. The government has historical records related to the agreement, but the status of the original signed document remains uncertain.

The Sugauli Treaty was concluded between the Kingdom of Nepal and the British East India Company in 1816 after the Anglo-Nepalese War. It became a major historical reference for the boundary between Nepal and territories controlled by British India. The agreement continues to feature prominently in discussions surrounding Nepal’s western territorial claims.

The issue has gained particular significance amid the continuing disagreement over Lipulekh, Kalapani and Limpiyadhura. Nepal maintains claims over these areas based on its interpretation of historical boundary arrangements, while India does not accept those claims.

The renewed focus on the treaty also comes as the Lipulekh Pass remains a sensitive point in India-Nepal relations. Kathmandu has objected to trade activity through the pass involving India and China, arguing that the area falls within Nepali territory.

However, the absence or uncertain status of an original treaty copy does not by itself determine the modern international boundary. Historical maps, subsequent agreements, administrative records, surveys and other official evidence also form part of boundary discussions.

The controversy nevertheless raises questions about the preservation of Nepal’s historical state records. The issue is especially significant because treaty documents dating back more than two centuries can continue to influence present-day diplomatic and territorial debates.

Nepal and India share close political, economic and people-to-people ties, but their unresolved boundary questions periodically create diplomatic friction. Both countries have mechanisms for discussing outstanding border matters through bilateral channels.

For Kathmandu, confirming the location and authenticity of important historical documents could become increasingly significant as it seeks to substantiate its position on disputed areas. For New Delhi, the latest development does not alter its established position on the boundary question.

The Sugauli Treaty remains a significant chapter in the history of Nepal-India relations. Its uncertain archival status has now added another layer to a border debate that continues to carry political and strategic importance across the Himalayan region.
