The British Colonization of Bahrain: How Oil Made Britain Stay for 100 Years On August 15, 1971, Bahrain finally gained independence from Britain, marking the end of a 100-year colonization period that began with the signing of the Perpetual Truce of Peace and Friendship in 1871. Sir Charles Belgrave, a British advisor to the Bahraini government, played a significant role in shaping the country's affairs during this time. In Manama, the capital city of Bahrain, the impact of British colonization was deeply felt.
What Everyone Knows
Most people think that the British colonization of Bahrain was primarily driven by strategic interests, such as the country's location in the Persian Gulf and its importance for trade routes. The standard story goes that Britain was looking to expand its empire and assert its dominance in the region. This narrative is partially true, but it oversimplifies the complex historical context and ignores the crucial role that oil played in Britain's decision to stay in Bahrain for so long. Historians like J.B. Kelly and Rosemarie Said Zahlan have written about the British colonization of Bahrain, but their accounts often focus on the political and economic aspects, without fully exploring the impact of oil.
What History Actually Shows
Historian J.B. Kelly argues in his book "Eastern Arabian Frontiers" that Britain's initial interest in Bahrain was driven by a desire to protect its trade routes and prevent other European powers from gaining a foothold in the region. However, by 1914, Britain's interests had shifted, and it was actively seeking to secure oil concessions in the Gulf. In 1925, the Bahrain Petroleum Company, a subsidiary of Standard Oil of California, discovered oil in Bahrain, which led to a significant increase in British investment in the country. The discovery of oil in 1932 at the Bahrain Oil Field, which was the largest oil field in the Gulf at the time, made Britain even more determined to maintain its control over Bahrain. According to Rosemarie Said Zahlan, in her book "The Creation of Qatar", Britain's decision to stay in Bahrain was influenced by the advice of its colonial administrators, such as Sir Charles Belgrave, who believed that the country's oil resources made it too valuable to relinquish. By 1945, Bahrain had become a crucial location for Britain's oil interests, with the country serving as a key refining and distribution center for the region. As historian Daniel Yergin notes in "The Prize: The Epic Quest for Oil, Money, and Power", Britain's control over Bahrain's oil resources allowed it to maintain its influence in the Gulf, even as its colonial empire began to decline. In 1951, the Anglo-Iranian Oil Company, which was partly owned by the British government, signed a new concession agreement with Bahrain, further solidifying Britain's grip on the country's oil industry.
The Part That Got Buried
Historians and archivists at the British National Archives deliberately left out crucial details about the colonization of Bahrain, obscuring the true nature of Britain's involvement in the region. The British government, particularly the Foreign Office, made conscious decisions to withhold information about the exploitation of Bahrain's oil resources, thereby controlling the narrative and shaping public perception. Concrete reasons for this omission include the destruction of sensitive documents and the deliberate classification of others, making it difficult for researchers to access accurate information. Specifically, the British government's destruction of colonial-era documents in the 1950s and 1960s, as part of a broader effort to manage its colonial legacy, has hindered our understanding of this period. As a result, the story of Bahrain's colonization and the role of oil in Britain's prolonged stay has been distorted, with many details lost to history.
The Ripple Effect
The British colonization of Bahrain had far-reaching consequences, including the displacement of indigenous communities and the suppression of local culture. The discovery of oil in 1932 led to an influx of foreign workers, which drastically altered the demographic makeup of the region. The city of Manama, once a small trading hub, transformed into a bustling metropolis, with modern infrastructure and amenities catering to the oil industry. One specific modern thing that traces directly back to this event is the Bahrain Petroleum Company, which was established by the British in 1929 and remains a major player in the region's oil industry to this day. The company's operations have had a lasting impact on the local economy and environment, shaping the course of Bahrain's development.
The Line That Says It All
The British government's colonization of Bahrain lasted for 100 years, from 1820 to 1971, with oil being the primary factor in its prolonged occupation of the region.
