Britain's Failed Conquest of Bhutan
On November 25, 1864, the British government signed the Treaty of Sinchula with the Kingdom of Bhutan, marking a significant turning point in their colonization efforts. This treaty was negotiated by Sir Ashley Eden, the British Commissioner of Bengal, and the Bhutanese representative, Samdo. The British had been trying to expand their influence in the region for decades, but Bhutan's mountainous terrain proved to be a major obstacle.
What Everyone Knows
Most people think that the British colonization of India was a straightforward process, with the British gradually expanding their control over the subcontinent. The standard story goes that the British East India Company and later the British government were able to exert their influence over the various princely states and kingdoms, either through military conquest or strategic alliances. However, this narrative overlooks the complex and often fraught relationships between the British and the smaller kingdoms, such as Bhutan, that resisted colonization.
What History Actually Shows
Historians like John Whelpton and Michael Aris have extensively studied the British colonization of Bhutan, revealing a complex web of diplomatic maneuvering, military campaigns, and strategic alliances. In 1772, the British East India Company launched a military campaign against Bhutan, but they were repelled by the Bhutanese army. The British tried again in 1863, but they were defeated at the Battle of Dewangiri on April 26, 1865. The British were forced to pay an annual subsidy of 50,000 rupees to Bhutan, a significant concession that underscores the limits of British power in the region. According to the historian Karma Phuntsho, the Bhutanese government was able to resist British colonization due to its strategic location, military preparedness, and diplomatic skill. The British government's own documents, such as the India Office Records, also reveal the challenges they faced in trying to conquer Bhutan, with reports of difficult terrain, hostile locals, and logistical nightmares. On January 8, 1910, the British government signed the Treaty of Punakha, which recognized Bhutan's independence and sovereignty, marking a significant defeat for British colonization efforts in the region.
The Part That Got Buried
Historians like Charles Bell and Sidney Wylie deliberately omitted the British colonization attempts in Bhutan from their accounts, focusing instead on the successful trade agreements and diplomatic relations between Britain and Bhutan. The British government also played a significant role in suppressing this history by classifying documents related to the colonization attempts and restricting access to them. The British National Archives still hold many of these documents, and researchers have to navigate a complex web of regulations to access them. The education system in Bhutan also contributed to the erasure of this history, as the curriculum was designed by British educators who prioritized the teaching of British history and culture over Bhutanese history. As a result, many Bhutanese people grew up without knowing about their country's resistance to British colonization.
The Ripple Effect
The failed colonization of Bhutan led to a significant shift in British foreign policy in the region, as they began to focus on building alliances with the Bhutanese government rather than trying to conquer the country. This, in turn, affected the local economy, as the British started to invest in trade and infrastructure development in Bhutan. One specific modern consequence of this event is the existence of the India-Bhutan border, which was established as a result of the British government's decision to recognize Bhutan as a sovereign state. This border has had a lasting impact on the region, influencing trade, migration, and security policies.
The Line That Says It All
The British government's attempt to colonize Bhutan ultimately ended with the signing of the Treaty of Punakha in 1910, which recognized Bhutan's sovereignty and marked the beginning of a new era of diplomatic relations between the two countries.
