Here’s the lowdown on how Brunei ended up losing control of Sabah: basically, a long, complex historical dance of treaties, cessions, and the growing influence of European powers, particularly the British. While Brunei had a historical claim, its declining power and the rise of the British North Borneo Company ultimately led to Sabah (then known as North Borneo) becoming a British protectorate and later part of Malaysia, leaving Brunei’s historical claims largely unrecognised.
The Early Days: Brunei’s Influence and Decline
To understand how Sabah slipped from Brunei’s grasp, we first need to rewind a bit and look at the Brunei Sultanate’s historical reach and its subsequent decline. For centuries, Brunei was a dominant maritime power in Southeast Asia, with its influence stretching across Borneo and the Sulu Archipelago.
Brunei’s Sultanate at its Zenith
During its golden age, roughly from the 15th to the 17th century, the Sultanate of Brunei held sway over a vast territory. This wasn’t necessarily direct administrative control in the modern sense; rather, it was a system of suzerainty, where local rulers acknowledged the Sultan of Brunei as their overlord, paying tribute and offering allegiance. This network of influence was vital for trade, particularly in commodities like spices, camphor, and jungle produce, which were highly sought after by regional and international traders. The northern coast of Borneo, including what we now call Sabah, was very much within this sphere of influence. Historical records, including Spanish and Portuguese accounts, attest to Brunei’s power and the extent of its territorial claims. This was a period when the Sultanate was not just a political entity but also a major economic and cultural hub in the region.
The Slow Erosion of Power
However, by the 18th century and certainly by the 19th, Brunei’s power began to wane. Several factors contributed to this decline. Internal strife, succession disputes, and challenges from regional rivals, such as the Sulu Sultanate, weakened the central authority. Piracy also became a significant problem, disrupting trade routes and making it difficult for the Sultanate to maintain control over its outlying territories. These internal and external pressures meant that Brunei’s ability to exert direct control over far-flung areas, like North Borneo, diminished significantly. While the nominal claim might have remained, the practical reality was that central authority was weakening, creating a vacuum that others would eventually fill. This period set the stage for the entry of European powers, who were keen to exploit the region’s resources and establish strategic outposts.
The Sulu Sultanate’s Contested Claim
Another key player in this historical narrative is the Sulu Sultanate, which also laid claim to parts of North Borneo. Their involvement adds another layer of complexity to the question of who truly “owned” Sabah.
The 1704 Cession and its Ambiguity
The most crucial piece of the puzzle regarding Sulu’s claim dates back to the early 18th century, specifically around 1704 (though some sources cite 1658 or 1665). The story goes that the Sultan of Brunei, facing a rebellion and needing military assistance, sought help from the Sultan of Sulu. In exchange for this help, Brunei supposedly ceded territories in North Borneo to Sulu. This agreement is often referred to as the “Cession of North Borneo.”
The critical point here, and one that remains a subject of intense debate, is the exact nature of this cession. Was it a complete transfer of sovereignty, or was it merely a lease? The original texts, often written in Jawi script and with varying interpretations, are ambiguous. The Sulu Sultanate consistently argued it was a cession of sovereignty, granting them full ownership. Brunei, on the other hand, maintained it was more of a grant of usufructuary rights – essentially, the right to use and profit from the land, but not outright ownership, and often with a condition of tribute or payment. This fundamental disagreement over the 1704 agreement forms the bedrock of the ongoing dispute between Malaysia (as successor to Sulu’s claims) and the Philippines (which champions Sulu’s historical rights). The exact boundaries of the ceded territory were also vague, adding to the complexities.
Sulu’s Subsequent Assertions
Following the supposed cession, the Sulu Sultanate did exert influence and collect tribute from communities along the northern and eastern coasts of Borneo. They established trading posts and maintained a presence, further solidifying their claim in the eyes of many. However, their control, much like Brunei’s, was often loose and indirect, particularly in the interior regions. The Sultanate’s power also waxed and waned, and it too faced challenges from internal conflicts and the growing presence of European powers in the region. Despite these fluctuations, the Sulu Sultanate consistently viewed itself as the sovereign power over these territories, a perspective that would have significant repercussions later on.
The British Arrive: Charters and Concessions
The 19th century saw European colonial powers, particularly the British, becoming increasingly active in Southeast Asia. This period marks a decisive turning point in the fate of North Borneo.
The American Adventurers and Overbeck’s Role
The story truly begins to accelerate with the involvement of American entrepreneurs. In 1865, the American Consul in Brunei, Charles Lee Moses, obtained a ten-year lease from the Sultan of Brunei for a large tract of land in North Borneo. He then transferred these rights to an American trading company formed by Joseph William Torrey, Thomas Bradley Harris, and others. This company, however, struggled financially and ultimately failed.
Enter Baron von Overbeck, an Austrian consul-general in Hong Kong. He acquired the struggling American company’s rights in 1878. Recognizing the potential but also the financial and logistical challenges, Overbeck sought financial backing and political support. He found this in Alfred Dent, a wealthy British merchant. Together, they approached both the Sultan of Brunei and the Sultan of Sulu to solidify their claims over North Borneo.
The Key Treaties of 1877 and 1878
This is where the real legal wrangling begins. Overbeck and Dent, acting on behalf of what would become the British North Borneo Company, signed two crucial agreements:
1. The 1877/1878 Lease/Cession with the Sultan of Brunei: On 29 December 1877 (some sources cite 1878), an agreement was signed between the Sultan of Brunei and Overbeck and Dent. This agreement granted them extensive territories in North Borneo. Crucially, the language used here, similar to the 1704 agreement, is debated. Brunei maintains it was a lease (or ‘pajakan’ in Malay), meaning a temporary grant of rights in exchange for annual payments, implying that sovereignty remained with the Sultanate. The British, however, interpreted it as a cession of sovereignty.
2. The 1878 Grant from the Sultan of Sulu: Subsequently, on 22 January 1878, Overbeck and Dent secured a similar agreement from the Sultan of Sulu. This was particularly important given Sulu’s long-standing claims over parts of North Borneo. Again, the interpretation of this document is a point of contention. The English version often refers to a “grant and cession,” implying a transfer of sovereignty. The original Tausug/Malay version, however, uses terms like “padjak” or “pajakan,” which usually denote a lease or an agreement for the usufruct of land in exchange for payment. The annual payments made to the descendants of both the Sultan of Brunei and the Sultan of Sulu continue to this day, a fact that further fuels the debate over the nature of these original agreements.
These agreements, despite their ambiguities, provided the legal framework for the British North Borneo Company to establish its presence and begin administering the territory. From the British perspective, these documents were legitimate grants of sovereignty.
The Rise of the British North Borneo Company
With the agreements in hand, the stage was set for the formal establishment of British colonial power in North Borneo.
The Royal Charter and Administration
In 1881, the British government granted a Royal Charter to the British North Borneo Provisional Association Limited, which was then formally reconstituted as the British North Borneo Company (BNBC). This Royal Charter was a significant development, as it bestowed immense powers upon the company, including the right to govern, administer justice, raise taxes, and maintain armed forces, all under the general oversight of the British Crown. The rationale behind granting a charter to a private company was often driven by the British government’s desire to expand its influence without incurring the direct costs and responsibilities of full colonial administration.
The BNBC established its capital at Sandakan and began to systematically develop the territory. They introduced a legal system, built infrastructure like roads and railways, encouraged agriculture (especially rubber and tobacco plantations), and suppressed piracy. While these developments brought a degree of order and economic growth, they were fundamentally driven by colonial interests and often came at the expense of local communities and their traditional ways of life. The company’s administration effectively superseded any remaining direct influence from Brunei or Sulu.
Brunei as a British Protectorate
During this same period, Brunei itself was facing increasing pressure from the British. Sarawak, under the Brooke dynasty (often referred to as the White Rajahs), had steadily expanded its territory at Brunei’s expense, supported by the British. By 1888, the British, keen to secure their strategic interests and prevent other European powers from gaining a foothold, declared Brunei a British Protectorate. This move formally ended Brunei’s independent foreign policy and placed it under the protection and influence of the British Crown. While Brunei remained a sovereign state in name, its effective power was severely curtailed.
This declaration of protectorate status for Brunei, coupled with the Royal Charter granted to the BNBC, cemented the separation of North Borneo from Brunei’s direct control. From the British perspective, North Borneo was now under the administration of a British chartered company, and Brunei’s historical claims were largely superseded by these more recent agreements and the overarching British imperial strategy. The annual payments to Brunei continued, but they were seen by the British as a form of rent rather than an acknowledgment of residual sovereignty.

The story of North Borneo didn’t end with the British North Borneo Company. It continued through World War II, British colonial rule, and ultimately led to the formation of Malaysia.
From Colony to Malaysia
During World War II, North Borneo was occupied by the Japanese, causing immense destruction. After the war, the British North Borneo Company, financially exhausted, ceded North Borneo to the British Crown, making it a Crown Colony in 1946. This marked the end of private company rule and direct British colonial administration.
In 1963, as part of the decolonisation process, the Federation of Malaysia was formed. North Borneo, along with Sarawak, Singapore, and the existing states of Malaya, joined to create the new nation. Before joining Malaysia, the territory was renamed Sabah. A referendum was held, and a commission (the Cobbold Commission) was established to gauge public opinion in North Borneo and Sarawak regarding their inclusion in Malaysia. The findings suggested significant support for joining, albeit with certain conditions, which were enshrined in the 20-point agreement for Sabah.
Crucially, from Malaysia’s perspective, Sabah’s entry into the federation was based on the premise that the British Crown, as the successor to the BNBC’s rights and later as the direct colonial power, held full sovereignty over the territory. Therefore, when the British transferred this sovereignty to Malaysia, it was deemed legitimate and complete.
The Philippines’ Persistent Claim
However, the question of who truly owns Sabah continues to be a point of contention, primarily from the Philippines. The Philippines bases its claim on the historical rights of the Sulu Sultanate. They argue that the 1878 agreement between the Sultan of Sulu and Overbeck/Dent was not a cession of sovereignty but merely a lease. Therefore, when the British North Borneo Company and subsequently the British Crown, and then Malaysia, took control, it was without the legitimate transfer of true sovereignty from the rightful owner, the Sultan of Sulu.
The Philippines views the annual payments made to the Sulu Sultan’s heirs as proof that it was merely a lease. They contend that the territory was only leased, not sold, and that sovereignty was never transferred. In the early 1960s, the Philippine government officially revived the claim, asserting its sovereign rights over Sabah. This claim has been a recurring diplomatic issue between Malaysia and the Philippines, resurfacing periodically.
Brunei’s Position
Brunei, while it has acknowledged the historical context, has generally not actively pursued its own sovereign claim over Sabah in the same way the Philippines has. Brunei’s historical claims largely predate the Sulu Sultanate’s involvement and the subsequent British agreements. While Brunei does maintain that the 1877/1878 agreement was a lease, its focus since its full independence in 1984 has been on its own national development and maintaining good relations with its neighbours, including Malaysia. The annual payments from Malaysia to the descendants of the Sultan of Brunei, much like those to the Sulu Sultan’s heirs, continue as a legacy of the original agreements.
Ultimately, “How Brunei lost Sabah” is a story of a powerful Sultanate gradually losing its grip, of contested historical treaties, and of the overwhelming force of European colonial expansion. The interpretations of those crucial 19th-century agreements continue to shape geopolitical realities and historical narratives in the region today.
FAQs
