Busaidi Sultanate

The Busaidi Sultanate in East Africa traces its origins to a time before its formal establishment. In 1652, under the leadership of the Ya’rubi imams, the Arabs of Oman freed themselves from Portuguese rule and gradually expelled them from all their East African territories north of Mozambique. However, internal conflicts in Oman led to the Busaidi gaining control of their homeland in 1744.
Despite this, resistance in Oman prevented them from asserting authority in East Africa throughout the eighteenth century. During this period, coastal communities remained largely autonomous, governed by their own ruling families without Busaidi interference. Among the most influential of these were the Mazrui clan, who controlled Mombasa along with smaller neighboring city-states such as Vumba.
Meanwhile, the Nabahany of Pate rivaled the Mazrui in influence along the northern coast. Only Zanzibar appeared to remain consistently loyal to the distant Omani sultans.
The Busaidi’s direct involvement in East Africa began in 1813 when Sayyid Said bin Sultan staked his claim. Responding to an invitation from local elders seeking protection from Mazrui and Nabahany hostilities, he successfully stationed a military garrison in Lamu. Soon after, Pate also housed a contingent of the Sultan’s loyal Baluchi troops.
However, permanent control over Pate and Pemba was not decisively secured until 1822, when the final Mazrui resistance, along with their supporters and slaves, was expelled. The formal establishment of the Busaidi Sultanate in East Africa did not occur until 1840, the year Sayyid Said permanently moved his capital from Muscat to Zanzibar.
As global demand for East African commodities expanded in the nineteenth century, Arab and Indian traders and plantation owners—led by the sultans—strengthened the connection between local economies and international trade networks. Plantation agriculture increasingly supplied global markets with cloves and grains. Simultaneously, newly established trade routes from the coast to the deep interior facilitated the movement of commodities such as ivory and animal hides. Following Sayyid Said’s relocation, Omani influence in East Africa grew considerably.
Economic transformations were key to this growing influence. The Sultanate thrived by fostering closer interactions with and reliance on global markets. Subsistence farming gradually gave way to large-scale plantations cultivating export crops such as cloves and grains.
At the same time, the increasing international demand for raw materials, including iron and animal hides, along with the local need for slaves to work the plantations, expanded caravan routes linking the interior to the coast. The Busaidi rulers played a direct role in these enterprises, with Sayyid Said and his successors maintaining vast plantations and participating in the caravan trade.

The Busaidi faced opposition both in East Africa and in Oman. Their rise to dominance was met with resistance from rival factions. In Zanzibar, the Harthi clan sided with disgruntled Busaidi family members in attempts to challenge the sultanate, causing disturbances during the reigns of both Sayyid Said and his successor, Majid.
In Mombasa, the Mazrui were not fully removed from power until 1837, and even then, they continued to challenge the sultanate and its British allies. One particularly defiant Mazrui leader, Mbarak bin Rashid of Takaungu, repeatedly shifted his allegiance—swearing loyalty at times, only to rebel soon after—until Mazrui resistance was decisively crushed by British-led forces under Sultan Hamid bin Thuwayn in 1895.
Similarly, the Nabahany dynasty, which had long ruled Pate, was eventually forced to retreat inland. Seeking to maintain authority, Ahmad Simba Nabahany declared an independent sultanate at Witu, briefly receiving German protection. However, like the Mazrui at Takaungu, the Witu Sultanate was ultimately subdued in 1896.
A fundamental vulnerability of the Busaidi Sultanate was its growing reliance on British support. Oman’s largest trading partner was British-controlled India, and British backing was crucial in enabling Sayyid Said to consolidate power in Oman before shifting his residence to Zanzibar. The British viewed the Busaidi as a stabilizing force in both East Africa and the Gulf region, as well as cooperative allies in efforts to regulate the slave trade.
However, this support came at a cost. Over time, the Busaidi sultans had to accept increasing British influence over their affairs. A series of treaties gradually curtailed the slave trade, starting with agreements in 1822, 1847, and 1873. A more comprehensive treaty in 1876 banned the trade entirely, and in 1897, the compliant Sultan Hamud bin Muhammad issued a decree officially abolishing slavery in Zanzibar.

These treaties strained relations between the sultanate and its Muslim subjects, many of whom resented foreign—particularly non-Muslim—interference in their economic and political affairs.
Caught between the demands of their subjects and the dominance of the British, the sultans had little choice but to yield to British pressure. Some, such as Barghash, Khalifa, and Ali, sought to resist European encroachments and limit concessions, but a series of external threats forced them into deeper dependence.
One major factor was the role of British consuls in mediating succession disputes within the Busaidi ruling family, further undermining the sultanate’s autonomy. Another pressing issue was the expansionist ambitions of Khedive Ismail of Egypt, who sought to seize control of East African coastal territories. Only British intervention prevented this from happening.
The situation worsened in the 1880s when European imperial ambitions placed additional pressure on the sultanate. In 1884, both Germany and Britain formally staked territorial claims in East Africa, compelling the sultans to accept British “protection.”
This arrangement ultimately led to the cession of Kenya to British control. By the reign of Sultan Hamud bin Muhammad, British dominance over the sultanate was nearly absolute. From that point onward, the Busaidi sultans ruled as figureheads under the authority of British colonial administrators.

This situation persisted until Zanzibar gained independence. However, independence proved disastrous for the Busaidi dynasty. In the revolution of 1964, approximately 5,000 Arabs were massacred, and the last reigning sultan, Abdullah bin Khalifa, was forced into exile.
