A New World (1950s): Oman, there's Trouble in the Jebel!
In the early 1950s, the Sultanate of Muscat and Oman was one of the most backwards and underdeveloped nations on Earth. It was in effect divided between two administrations: Interior Oman, a region of conservative Ibadi tribesmen ruled by an Imam who was elected for life; and the Sultanate, which was comprised of Muscat, Dhofar and the overseas possession of Gwadar (in Baluchistan). The peoples of the Sultanate were outward-oriented sailors and merchants, whilst the rugged tribesmen of the interior were pious, conservative and xenophobic. There had been friction between the interior and the coast before, but the Treaty of Seeb (signed in 1920) brought to an end the most recent revolt from the Imamate. It was decided that whilst the Sultan would have control over all external affairs from his seat in Muscat, the Imam would have very high levels of autonomy over the internal affairs of Interior Oman. The Imam had, in essence, his own throne in the town of Nizwa.
Despite this agreement, friction between the Imamate and the Sultan intensified in the 1950s. In the early 1950s, the joint American-Saudi oil company, ARAMCO, showed interest in the commercial quantities of crude oil believed to exist under the Buraimi Oasis, on the border of Oman, Saudi Arabia and the Emirate of Abu Dhabi. The Buraimi Oasis area contained nine villages, three of which lay inside Oman and six of which lay within Abu Dhabi's lands. The Saudis made claim to the oasis, based on a tenuous claim from the Wahhabi occupation of the oasis which ended in 1869, when they were expelled by the Sultan with the assistance of a local tribe. Both Oman and Abu Dhabi asked the British to represent them in negotiations with the Saudis. The British agreed (they were already legally-obligated to represent Abu Dhabi under the terms of the Treaty of Maritime Peace and Prosperity).
In order to negotiate from a position of strength, the Saudis sent a garrison of forty men under the command of Turki bin Abdulla bin Ataishan to occupy the oasis. Sultan Said bin Taimur, with the assistance of Imam Muhammad al-Khalili, mustered a force of 8,000 tribesmen at Sohar on the coast, prepared to oust the Saudis from the oasis. In the meanwhile, a standstill agreement was reached between the Saudis and the British in Jiddah with the mediation of the American ambassador to Saudi Arabia. The British persuaded the Sultan to abandon any military action against the Saudis. The fierce tribesmen of Oman reluctantly went home, but the legitimacy of the Sultan in their eyes had been decisively undermined.
The Saudi garrison in Buraimi was isolated by the forces of the Trucial Oman Levies, a British-officered force responsible for ensuring the safety and stability of the so-called "Trucial States", a number of Persian Gulf sheikhdoms that were under a British protectorate. The 'benevolent siege' included no shooting between the opposing forces, but no movement was allowed into or out of the Buraimi Oasis. It is believed, however, that Omani soldiers in the Levies were selling ammunition to their Saudi counterparts. The only military action of the siege was an ambush on the convoy of the British commander, not by Saudi troops, but by his own. The commander, Otto Thwaites, was killed in a crossfire, along with his Jordanian sergeant-major and a doctor from the RAF.
In 1954, the Buraimi question was referred to an international arbitration tribunal in Geneva. On the orders of the tribunal, a Saudi police detachment moved into the oasis and a small force from the Trucial Oman Levies were stationed inside the area, whilst a 15-mile demilitarised zone was established around the oasis. The British made a dramatic about-turn in the September of 1955. The British representative walked out of the Geneva negotiations, angered at the Saudis' lack of impartiality. In a complete reversal of their prior policy, the British encouraged the Sultan and the Emir of Abu Dhabi to occupy Buraimi. In October of that year, a force of Trucial Oman Levies, disguised as a relief column for its Buraimi garrison, rounded up the Saudi police detachment, installed a
wali (governor/custodian) of the Sultan's in Buraimi fort and invited a detachment of the Sultan's own troops to establish themselves in the oasis.
Whilst it may appear at first glance that the Sultan was victorious, the Sultan's authority had been severely undermined in Interior Oman. During the three years since the tribesmen had returned home from Sohar, the Saudis had been increasingly active in promoting themselves in the Imamate. The Saudis gave the
tamimah (chieftains) of the tribes gifts of money, modern arms and in the case of Sulayman ibn Himyar al-Nabhani of the Bani Riyam (and self-proclaimed "Lord of
Jebel Akhdar", or "Green Mountain"), a 1953 Chevrolet convertible, the only automobile in Oman. The Sultan's authority took a further blow in 1954 with the death of Imam Muhammad al-Khalili. al-Khalili had been no puppet of the Sultan, but he had proven willing to cooperate. He was replaced by the Imam Ghalib bin Ali, who had been elected due to the bribery of the Saudis. Ghalib was supported by his brother Talib, the wali of Rustaq at the time, as well as by al-Nabhani. Ghalib proved to be more insolent than Imam Muhammad.
Relations between the Sultan and the new Imam were torn asunder over an oil dispute. Petroleum Development Oman, a subsidiary of the British-owned Iraq Petroleum Company (itself a subsidiary of the Anglo-Iranian Oil Company), had shown interest in a promising geological formation in the vicinity of
Jebel Fahud ("Leopard Mountain"). The Sultan claimed that all dealings with oil companies were an external matter, subject to his authority in the Treaty of Seeb. The Imam disagreed, claiming that the area's position inside the territory of the Imamate made it his prerogative. In an attempt to pre-empt the Imam, the Sultan licensed oil prospectors to search in the area, and they were welcomed by the local Ibriyin tribe, much to the chagrin of the Imam, who wanted the foreigners expelled. The Imam responded by declaring the independence of the "State of Oman" from Muscat and applied for membership in the Arab League (a move which was sponsored by the Saudis). Tribesmen loyal to the Imam raided the Ibriyin on the Imam's orders. In response, the Sultan sent two British employees of Petroleum Development Oman, along with the Muscat and Oman Field Force north from Fahud to seize Ibri in October 1955. The occupation of Ibri cut off the Imam from Saudi support. Unable to tolerate the loss of Saudi supplies, the Imam travelled to Bahla with the intention of driving the Sultan's forces out. Aided by the Bani Riyam, the forces of the Imamate drove the Field Force from Ibri. Although the Omani forces (largely Balochs from Gwadar) fought steadfastly, they were eventually forced to withdraw to avoid being overrun by the better-equipped tribesmen.[91]
Whilst the Field Force withdrew from Ibri, the Bartinah Force, under the command of Lt.Col Colin Maxwell, attacked the fortress of Rustaq. The Bartinah Force met determined resistance from the Rustaqis, commanded by their wali, Ghalib's brother Talib. Although they had begun to make progress against the defenders, having limited them to the fortress itself, the Bartinah Force was caught by tribal forces who had rode East from Ibri to relieve the defenders. The Bartinah Force fought bravely, but was largely destroyed. Having defeated the bulk of the Sultan's army, the Imam's forces marched towards Muscat to force the acquiescence of the Sultan. The Sultan, despite British pressure, bowed to the Imam's terms, granting Oman independence from his realm, now known as the Sultanate of Muscat and Dhofar. Despite his surrender, there were renegade tribesmen who wished to get revenge on the foreign prospectors for their perceived insolence. They continued to march on Muscat anyway, where the remainder of the Field Force had withdrawn to. Although the Sultan's forces seemed capable of fending off the tribal incursion alone, and put up stiff resistance to the tribesmen on the outskirts of the city, a small force of British commandos bolstered their defences and evacuated personnel of Petroleum Development Oman. This conflict became known as the "Jebel Fahud Affair".[92]
[91]IOTL, al-Nabhani for some reason didn't aid the Imam, so he couldn't attack the Sultan's forces at Ibri. Which also meant that the forces at Rustaq were forced to surrender. Incidentally, Talib escaped, and the rebellion was put down, although it was reignited in 1957, where he had a better showing, but was eventually forced to withdraw to Jebel Akhdar, where the British had to send in the SAS to dislodge them from their excellent position atop the mountain. ITTL, the rebellion is successful in its first phase.
[92] IOTL, it is the "Jebel Akhdar War", not the "Jebel Fahud Affair".
