Cooch Behar and Bhutan

Cooch Behar (also spelled Koch Bihar) is a region in the northern part of West Bengal, India, whose history is deeply entwined with that of Bhutan. The Koch kingdom, which rose to prominence in the sixteenth century under Maharaja Naranarayan and his brother Chilarai, controlled vast territories stretching from the Brahmaputra valley to the foothills of the eastern Himalayas. For centuries, the boundary between Koch and Bhutanese territories was fluid and contested, with both powers vying for control of the strategically and economically vital Duars — the fertile lowland corridor along Bhutan's southern frontier.^[1]

The conflicts between Cooch Behar and Bhutan reached their most consequential phase in the eighteenth century, when Bhutanese forces repeatedly intervened in Koch political affairs, at times deposing and installing rulers. These interventions provoked Cooch Behar to seek British military assistance, a decision that would prove fateful for both Cooch Behar and Bhutan. The resulting British involvement in the region set in motion a chain of events that led to the Duar War of 1864-65 and the permanent alteration of Bhutan's southern boundaries.^[2]

The relationship between Cooch Behar and Bhutan is thus central to understanding the formation of Bhutan's modern borders and the broader geopolitics of the eastern Himalayan region. It illustrates how the interplay between a Himalayan kingdom, a plains-based principality, and a European colonial power reshaped the political landscape of South Asia.

Historical Context

The Koch kingdom was established in the early sixteenth century by Biswa Singha, who unified the Koch, Mech, and other tribal communities of the Brahmaputra valley into a powerful state. Under his successors, particularly Naranarayan (r. 1533-1587), the kingdom expanded significantly, controlling territory that encompassed much of present-day northern Bengal, western Assam, and parts of Bihar. The Koch kings adopted Hinduism and patronised Sanskrit learning, but their subjects included diverse ethnic and religious communities.^[3]

Bhutan's interactions with Cooch Behar centred on the Duars, a series of narrow valleys and plains that served as passes (the word "duar" means "door" or "gateway") between the Bhutanese hills and the Indian lowlands. Bhutan claimed sovereignty over the Duars and collected revenue from the communities living there. Cooch Behar, whose northern territories abutted the Duars, contested these claims, leading to recurrent border skirmishes and diplomatic disputes throughout the seventeenth and eighteenth centuries.^[4]

The situation was complicated by the internal politics of both states. Bhutan in this period was governed by a dual system of spiritual and temporal authority, with the Zhabdrung as the supreme religious leader and the Druk Desi as the chief administrator. Factional rivalries within the Bhutanese court sometimes led to aggressive external policies, including military expeditions into Cooch Behar territory. Similarly, succession disputes within the Koch royal family created opportunities for Bhutanese intervention.^[5]

Bhutanese Connection

The most dramatic episode in the Cooch Behar-Bhutan relationship occurred in 1772, when Bhutanese forces invaded Cooch Behar, seized the capital, and installed a puppet ruler. The deposed Koch king appealed to the British East India Company for military assistance. The Company, eager to expand its influence in the region and to establish commercial contact with Tibet, agreed to intervene. A British expeditionary force under Captain John Jones marched into Cooch Behar, defeated the Bhutanese garrison, and pursued the retreating forces into the Duars.^[6]

This conflict, sometimes called the Cooch Behar War or the first Anglo-Bhutanese conflict, resulted in the Treaty of 1774, in which Bhutan agreed to withdraw from Cooch Behar territory. The treaty also opened the way for the first British diplomatic mission to Bhutan and Tibet, led by George Bogle, which passed through Kalimpong and into the Bhutanese interior. The Cooch Behar crisis thus served as the catalyst for the beginning of direct Anglo-Bhutanese relations.^[7]

Relations between Cooch Behar and Bhutan remained tense throughout the nineteenth century. Disputes over the Duars continued, and the British gradually assumed a greater role in mediating — and ultimately dictating — the terms of the relationship. The final resolution came with the Duar War of 1864-65, in which British forces seized the entire Duars region from Bhutan. The Treaty of Sinchula (1865) formalised the transfer, and Bhutan's southern frontier was pushed back to the foothills. Cooch Behar, now firmly within the British sphere of influence, was absorbed as a princely state and later merged into independent India in 1949.^[8]

Modern Relations

In the modern period, the Cooch Behar district of West Bengal shares a border with Bhutan's southwestern districts. Cross-border trade continues through designated border points, and economic ties between the two regions remain significant. Bhutanese agricultural products, including oranges, cardamom, and timber, find markets in Cooch Behar, while Indian manufactured goods flow in the opposite direction.^[9]

The Indian government and the Royal Government of Bhutan have cooperated on infrastructure projects in the border region, including road construction and hydroelectric development. The historical legacy of conflict has been largely replaced by a relationship characterised by economic cooperation and diplomatic goodwill, though the memory of the Duar Wars and the territorial losses continues to inform Bhutanese historical consciousness.

Cultural Ties

Despite the history of conflict, Cooch Behar and Bhutan share deep cultural connections rooted in their geographical proximity and overlapping ethnic communities. The Koch, Mech, and Bodo peoples of Cooch Behar are linguistically and culturally related to communities in southern Bhutan. Festivals, agricultural practices, and folk traditions on both sides of the border reflect a shared heritage that predates the political boundaries imposed in the nineteenth century.^[10]

The Cooch Behar Palace, a grand Italianate structure built in 1887, houses a museum that includes artefacts relating to the Koch kingdom's interactions with Bhutan. Historical documents, weapons, and diplomatic correspondence preserved there provide valuable primary source material for scholars studying the Bhutanese-Koch relationship. The cultural landscape of Cooch Behar, with its blend of Hindu, Buddhist, and indigenous traditions, testifies to the centuries of contact between the plains and the hills.
