🇴🇲 Oman

Sumerian cuneiform texts of around 2300 BCE refer to the region as Magan, a source of copper and diorite for Mesopotamia that persisted until 550 BCE. Oman's mineral wealth thereby underpinned its earliest recorded external trade relations and gave the region standing in the ancient Near Eastern economy.

Scholars including John C. Wilkinson argued from oral history that the Achaemenids controlled the Omani peninsula in the 6th century BCE, probably ruling from a coastal centre such as Suhar, with northern Oman forming part of the Maka satrapy. The claim remains contested, since Persian archaeological finds in south-eastern Arabia are lacking.

Armand-Pierre Caussin de Perceval suggested that in 536 BCE Shammir bin Wathil bin Himyar acknowledged Cyrus the Great's suzerainty over Oman. The episode forms part of the disputed tradition of early Persian overlordship in south-eastern Arabia.

A segment of the Azd migrated from Yemen to Oman in 120/200 CE following the collapse of the Marib Dam, while a second group, the Nizari, came from Nejd a few centuries before Islam. These Arab migrations reshaped Oman's tribal composition and established the lineages from which many present-day Omani families claim descent.

Sasanian forces under Vahrez subdued the Omani Kingdom during the Aksumite–Persian wars, stationing a 4,000-strong garrison headquartered at Jamsetjerd, the modern Jebel Gharabeh. Persian military presence shaped the political geography of Oman on the eve of Islam.

During the 7th century Omanis came into contact with Islam, with the conversion ascribed to Amr ibn al-As, sent by Muhammad to meet Jaifer and Abd, the sons of Julanda who ruled Oman. Their ready embrace of the new faith bound Oman into the emerging Islamic world and set the religious foundation of the state.

After Muhammad's death, Laqit ibn Malik al-Azdi led a rebellion seizing much of Oman; Abu Bakr dispatched Hudhayfa ibn Mihsan and Arfaja ibn Harthama, joined by the Omani rulers Jaifar and Abd. The rebels were decisively defeated at Dibba, restoring Rashidun authority and securing Oman's incorporation into the expanding Islamic state.

Ibadism emerged in Basra under Abd Allah ibn Ibad as a moderate branch of the Kharijites, following the rejection of arbitration at the Battle of Siffin. The Omani Azd in Iraq adopted it as their predominant faith, and the return of scholars such as Jaber bin Zaid after conflict with al-Hajjaj entrenched Ibadism in Oman, defining its distinct religious identity.

Shortly after the fall of the Umayyad dynasty an elective Imamate was founded, with Janah bin Ibadah Alhinnawi elected, though other accounts name Julanda bin Masud as first elected Imam in 751 CE. The Imamate created an enduring indigenous constitutional tradition of elected religious leadership that recurred in cycles for over 1,200 years.

The Imamate reached its peak power in the ninth century, its fleet dominating the Gulf while trade flourished with the Abbasid dynasty, the Far East and Africa. Authority later declined through power struggles, Abbasid intervention and the rise of the Seljuk Empire.

The inhabitants of the area of Oman have for centuries thrived on Indian Ocean commerce, trading frankincense, dates and later slaves and goods between Africa, Arabia and Asia.

The Seljuk sphere of influence over the Omani coast was ended in 1154 when the Nabhani dynasty took power, ruling as muluk from a capital at Bahla while the Imams were reduced to symbolic significance. The Banu Nabhan controlled the overland frankincense trade via Sohar to Yabrin and onwards to Bahrain, Baghdad and Damascus.

Some historians date the fall of the Nabhani dynasty to 1435 CE, when conflict between the dynasty and the Hinawis led to the restoration of the elective Imamate. The episode marks the recurring tension in Oman between hereditary kingship and elected religious rule.

A decade after Vasco da Gama's voyage, Afonso de Albuquerque captured Hormuz and the Portuguese seized Muscat in 1507, extending control along the coast from Sohar to Sur and fortifying Muscat as an outpost protecting their sea lanes. The occupation integrated Omani ports into a chain of fortresses from Basra to Hormuz and precipitated the decline of the Nabhani dynasty.

In 1552 an Ottoman fleet seized Muscat's fort during the struggle for control of the Persian Gulf and Indian Ocean, but departed after destroying the surroundings of the fortress. The Portuguese later routed an Ottoman fleet decisively at the Battle of the Gulf of Oman.

Using bases in Oman, a Portuguese force engaged a combined armada of the Dutch and English East India Companies backed by the Safavid empire. The battle ended in a draw but cost Portugal its influence in the Gulf, opening the way for Omani resurgence.

The election of Nasir bin Murshid in 1624 reunited the Omanis under the Yaruba Imams. The dynasty provided the political cohesion that enabled the expulsion of the Portuguese and the creation of an Omani maritime empire.

Omani forces under the Yaruba Imams recaptured Muscat and drove the Portuguese from their coastal possessions in Oman, taking Muscat on 26 January 1650 and ending 143 years of foreign control dating from 1508. The Omanis then pursued the Portuguese overseas, expelling them from all their East African possessions, which were incorporated into Omani domains, and the Ya'arubi dynasty built Oman into a regional maritime power.

Pressing down the Swahili Coast to capture Zanzibar, Saif bin Sultan besieged the Portuguese garrison at Fort Jesus, Mombasa, which fell in 1698. The victory secured Omani dominance of the East African coast and the foundations of an Indian Ocean empire.

In 1700 the Omani Imam Saif bin Sultan occupied Bahrain, extending Omani power across the Gulf. The seizure illustrated the reach of Omani naval strength at the height of the Yaruba period.

Following the death of Imam Sultan bin Saif II in 1718, rival claimants fought for the imamate, weakening the Yaruba dynasty. Imam Saif sought help from Nader Shah of Persia, whose forces occupied parts of the country on two occasions between 1737 and 1744.

Ahmad bin Said al-Busaidi expelled the occupying Persian forces and was elected imam of Oman and sultan of Muscat on 20 November 1744, with Rustaq as his capital, ending the civil war and the Ya'aruba dynasty. His Al Bu Said (Al Said) dynasty has ruled Oman continuously ever since — making Oman the oldest independent state in the Arab world — and his descendants remain the ruling family today.

In 1798 Sayyid Sultan bin Ahmed signed the first treaty between the British East India Company and the Albusaidi dynasty, aiming to block French and Dutch commercial competition and to obtain a concession for a British factory at Bandar Abbas. It began a series of friendship agreements advancing British interests in Muscat in exchange for military protection; over time Oman's dependence on British political and military advisers increased, though it never became a British colony.

The 1800 treaty stipulated that a British representative would reside at the port of Muscat and manage all external affairs with other states. As the Omani Empire weakened, this arrangement steadily deepened British control over Omani foreign policy through the nineteenth century.

Zanzibar, the main slave market of the Swahili Coast and a major clove producer, became so valuable that Sa'id bin Sultan made it the capital of the Omani empire in 1837. The decision confirmed the African orientation of Omani wealth and power at its nineteenth-century peak.

In 1854 the sultan ceded the Kuria Muria islands to the British government. Britain thereby consolidated predominating control over Muscat and largely excluded competition from other nations.

Under British arbitration in 1856, Zanzibar and Muscat were divided into separate sultanates. The partition stripped Muscat of its African dominions and revenues, leaving the sultans dependent on British loans and obliged to consult Britain on all important matters.

Britain mediated the division of the Omani empire into two separate states in 1861, five years after the death of Sultan Said bin Sultan: the Sultanate of Zanzibar and the Sultanate of Muscat and Oman. The African territories were permanently lost to Omani rule.

As Political Residents between 1862 and 1892, Pelly and Ross built a system of indirect governance that entrenched British predominance in the Gulf and Muscat. By the end of the century the Sultanate had fallen de facto within the British sphere.

Azzan bin Qais began his rule as elected Imam in 1868, but Britain refused to accept him as ruler, judging him inimical to its interests. British backing was instrumental in his deposition in 1871 by his cousin Sayyid Turki, whom Britain deemed more acceptable.

From 1913 Imam Salim Alkharusi led a rising against the Sultanate, reflecting alienation of the interior caused by British influence over Muscat. The revolt lasted until 1920 and forced a negotiated settlement between Sultanate and Imamate.

The 1920 treaty ended the rebellion by granting autonomous rule to the Imamate in the interior while recognising the sovereignty of the Sultanate of Muscat over the coast. Britain brokered the deal, having then no economic interest in Oman's interior; the arrangement defined Oman's dual political structure for a generation.

The agreement of 10 January 1923 obliged the Sultanate to consult the British political agent in Muscat and obtain the approval of the High Government of India before extracting oil. It placed Oman's future hydrocarbon wealth firmly under imperial supervision.

On 31 July 1928 Anglo-Persian, Royal Dutch/Shell, Compagnie Française des Pétroles, Near East Development Corporation and Calouste Gulbenkian agreed to produce oil collectively across the post-Ottoman region including Arabia, with four majors holding 23.75 percent each. No signatory could pursue concessions in the area alone, and in 1929 the members founded the Iraq Petroleum Company.

Sultan Taimur bin Faisal abdicated on 13 November 1931. His son Said bin Taimur formally became sultan of Muscat on 10 February 1932, beginning nearly four decades of British-backed isolationist rule.

Said bin Taimur took the throne officially on 10 February 1932; his rule has been characterised as feudal, reactionary and isolationist. Britain retained vast administrative control, with the defence secretary, intelligence chief, chief adviser and all ministers but two being British.

The 1937 agreement gave oil concessions to IPC, a consortium 23.75 percent British owned. Having failed to find oil in the Sultanate, IPC was drawn to promising formations near Fahud inside the Imamate, and offered the sultan financial support to raise armed forces against Imamate resistance.

On 10 September 1939 the sultan declared war on Germany. Oman played a strategic role in defending British trade routes during the Second World War and was never attacked.

In 1943 the RAF built bases at Masirah and Ras al Hadd, with air-sea rescue units also stationed in Oman. Squadrons flew Blenheims, Wellingtons and Catalinas on anti-submarine duties over the Gulf of Oman and northern Arabian Sea, embedding Oman in Allied maritime defence.

On 16 October 1943 a Bristol Blenheim from No. 244 Squadron sank U-533 with depth charges in the Gulf of Oman. Fifty-two crew died and the sole survivor was taken prisoner; the wreck lies at 108 metres and is now a recreational diving site.

In 1946 Britain armed and advised the sultan's forces, its political agent in Muscat believing that access to interior oil reserves required helping the sultan take over the Imamate. The support laid the groundwork for the later Jebel Akhdar War.

The December 1951 treaty covered commerce, oil reserves and navigation and recognised the Sultanate of Muscat and Oman as a fully independent state. It formalised Oman's de jure sovereignty while British influence remained pervasive in practice.

In 1955 the exclave coastal Makran strip joined Pakistan and became a district of Balochistan province, while Gwadar remained Omani. The transfer marked the retreat of Omani territorial holdings beyond Arabia.

Led by Imam Ghalib, his brother Talib and Suleiman bin Hamyar, the interior defended the Imamate; in July 1957 the Sultan's withdrawing forces were repeatedly ambushed with heavy casualties. British infantry, armoured cars and RAF aircraft enabled the Sultan to suppress the rebellion, and the RAF flew 1,635 raids between July and December 1958, dropping 1,094 tons of bombs on villages, water channels and crops.

In December 1955 the Muscat and Oman Field Force occupied the main centres of the interior, including the Imamate capital Nizwa and Ibri. The move followed the 1954 election of Imam Ghalib Alhinai and their dispute over oil concessions, and triggered the Jebel Akhdar War.

The Chinese company began building a US$1 billion plant in Oman's Sohar Free Zone in May 2026 to produce anode materials for lithium-ion batteries. The plant forms part of Oman's strategy to become a regional hub for clean-energy manufacturing.

During a cabinet meeting on 28 May 2026, US President Donald Trump said Oman would be 'blown up' if it did not 'behave', after reports that Muscat and Tehran had discussed jointly charging a toll on shipping through the Strait of Hormuz.

Iranian fire shot down a US A-10 Thunderbolt attack aircraft off the coast of Bukha, Oman, on 3 April 2026. The pilot ejected and needed medical treatment, and the aircraft was destroyed, extending the conflict's reach into Omani territory.

Iranian foreign minister Abbas Araghchi met Sultan Haitham bin Tariq in Muscat on 25 April 2026 to discuss the regional conflict and mediation efforts to end it. Oman hosted repeated rounds of US-Iran diplomacy despite having itself been struck by Iranian drones.

Fahd bin Mahmoud al Said, Oman's deputy prime minister and a cousin of the sultan, died on 12 March 2026 aged 81 or 82. He had served as deputy prime minister since 1972, making him one of the longest-serving officials in the Gulf.

Iranian drone strikes hit the ports of Duqm and Salalah, an oil tanker near Khasab and an industrial area in Sohar through March 2026, killing several people and injuring dozens more. Iranian officials said some of the strikes on Oman were not ordered by Tehran.

Oman hosted indirect negotiations between Iran and the United States over Iran's nuclear programme in Muscat on 6 February 2026, continuing its long-standing role as a back-channel venue for talks between the two countries, weeks before open conflict broke out.

A tourist boat capsized in the Gulf of Oman off Muscat on 27 January 2026, killing three French nationals. The incident prompted renewed scrutiny of safety standards for tourist vessels operating along the Omani coast.

India signed a trade agreement with Oman in December 2025 as part of efforts to accelerate free trade deals and diversify export markets in response to higher United States tariffs. The deal was expected to expand market access for goods and services between the two countries.

UNESCO designated the Jebel Akhdar mountains and the Sirrin reserve in Oman as biosphere reserves on 27 September 2025, recognising their ecological value. The listing formed part of a wider expansion that year of the World Network of Biosphere Reserves.

Elections to the Majlis al-Shura were held on 29 October 2023, with the next due in October 2027. The regular electoral cycle remains the principal channel of formal popular participation under a system in which the Sultan legislates by decree.

A royal decree in April 2023 allowed Omani citizens to marry foreigners without government permission, ending a long-standing restriction. It formed part of incremental liberalisation of personal rights.

On 12 January 2021 Haitham designated his eldest son Theyazin bin Haitham as crown prince and heir, creating the position through a constitutional amendment. The change introduced a clear hereditary succession rule where previously none existed.

Sultan Qaboos bin Said died on 10 January 2020 after almost 50 years in power, the Arab world's longest-serving ruler at the time. His cousin Haitham bin Tariq was sworn in as sultan the following day, continuing the Al Said dynasty's rule.

In November 2019 Oman replaced routine visa on arrival with an electronic visa system open to tourists of all nationalities. The reform supported the tourism sector, which contributed 2.8 percent of GDP in 2016 and grew 42.3 percent between 2009 and 2017.

In September 2019 Oman was confirmed to host IGRC 2020, the conference's sixteenth iteration, held in February 2020 with Oman LNG under the auspices of the Ministry of Energy and Minerals. It marked recognition of Oman's position in global gas research and industry.

On 26 June 2018 Qurayyat recorded a minimum temperature of 42.6 °C over a 24-hour period, a global record. It underlined the extremity of Oman's climate, where peak temperatures approach 54 °C in the hot season.

The Sultanate's flagship cultural institution opened on 30 July 2016. It followed earlier institution-building including the Oman Centre for Traditional Music in 1984, the Royal Oman Symphony Orchestra founded in 1985, and the Omani Society for Fine Arts in 1993.

The World Health Organisation recognised Oman as having eliminated malaria diagnoses in 2013. It reflected sustained investment in public health that also produced above-99 percent childhood vaccination rates since 1995.

As part of efforts to decentralise authority and allow greater citizen participation in local governance, Oman successfully conducted its first municipal council elections in December 2012. Announced by the Sultan in 2011, the councils have the power to advise the Royal Court on the needs of local districts across Oman's 11 governorates.

From 2012 the authorities prosecuted activists accused of posting abusive and provocative online criticism of the government, with trials beginning in September 2012 and six people jailed. The episode signalled the limits of the post-2011 political opening.

In August 2012 the Sultan issued a royal directive mandating the speedy implementation of a national plan to create thousands of public and private sector jobs.

A site discovered in Dhofar Governorate in 2011 contained more than 100 surface scatters of stone tools belonging to the late Nubian Complex, previously known only from northeast Africa and the Horn of Africa. Optically stimulated luminescence dating placed the assemblage at 106,000 years old, supporting the proposition that early human populations moved from Africa into Arabia during the Late Pleistocene.

Inspired by the popular uprisings sweeping the Middle East and North Africa from January 2011, some Omanis staged marches, demonstrations and sit-ins calling mostly for political reform, better living conditions, more jobs, economic benefits and an end to corruption, without demanding the regime's overthrow; riot police dispersed protesters in February. In response, Qaboos pledged economic and political reforms, including job creation and unemployment benefits, amendments to the Basic Statute, and legislative and regulatory powers for the Majlis al-Shura elected that October.

The agreement took effect on 1 January 2009, eliminating tariff barriers on all consumer and industrial products and providing strong protections for foreign investors in Oman. It deepened Oman's integration into global trade and its diversification strategy.

In 2007 Oman contracted the VT Group for three Khareef class corvettes at a cost of £400 million. The order reflected sustained naval investment; Oman was the world's 23rd largest arms importer between 2012 and 2016 and its military spending reached 11 percent of GDP in 2020, the world's highest.

A 2007 decision reduced the sanctuary's area by ninety percent to clear the way for oil prospectors. As a result it became the first site ever deleted from UNESCO's World Heritage List, a notable reputational cost of hydrocarbon priorities.

Around 100 suspected Islamists were detained in 2005 and 31 convicted of attempting to overthrow the government. All were pardoned in June of the same year.

In 2004 Sheikha Aisha bint Khalfan bin Jameel al-Sayabiyah was appointed to head the National Authority for Industrial Craftsmanship. The appointment marked a symbolic advance for women in Omani public life.

In 2002 the franchise was extended to all citizens aged over 21, and the first Consultative Assembly elections under the new rules were held in 2003. Despite the reform, the Sultan continued to rule by decree with little change to the political makeup of government.

A royal decree in 1997 gave women the franchise and eligibility for election to the Consultative Assembly, and two women were duly elected. It was an early step in a gradual and limited widening of political participation.

Sultan Qaboos issued the Basic Statute of Oman by royal decree on 6 November 1996, the country's first written constitution and foundational constitutional document, promulgated as all legislation had been since 1970. It guaranteed a framework of rights under Islamic and customary law and set out rules for royal succession, and it has since been amended twice: in 2011 in response to protests, and in 2021 to create the position of Crown Prince.

In 1995 Oman adopted a flag resembling its predecessor but with a thicker stripe. The change accompanied the broader institutional consolidation of the Qaboos era.

Established in 1995, the plan targeted cutting oil's share of GDP to under 10 percent by 2020, but it was rendered obsolete in 2011 and replaced by Vision 2040. Diversification efforts intensified after the 1998 oil price slump, with emphasis on tourism and infrastructure.

Oman joined Bahrain, Kuwait, Qatar, Saudi Arabia and the United Arab Emirates in founding the Gulf Cooperation Council in 1981. The council became the main framework for economic and security cooperation among the six Arabian Peninsula monarchies.

Following the 1970s energy crisis Oman doubled its oil production between 1979 and 1985. The expansion funded the state's modernisation but deepened dependence on hydrocarbons, which still supplied 71 percent of government revenue in 2018.

Oman joined the United Nations and the Arab League in 1971, alongside Bahrain, Qatar and the United Arab Emirates, cementing its international recognition under Sultan Qaboos. Formal diplomatic ties with most Western and Arab states expanded over the following decade.

Qaboos bin Said deposed his father, Said bin Taimur, in a bloodless palace coup on 23 July 1970, with British backing and amid the Dhofar rebellion, and became sultan. He renamed the country the Sultanate of Oman, dropping 'Muscat and', abolished slavery, expanded the armed forces, modernised the administration and increased spending on health, education and welfare, launching the modernisation programme known as the Omani Renaissance after decades of isolation.

Slavery, long central to Oman's trade and development through the Zanzibar market, was abolished in 1970. The measure was part of the wider social reform programme that opened the country after Qaboos's accession.

The border of the Omani exclave of Madha was fixed in 1969, running within ten metres of the Fujairah road at its north-east corner. The settlement resolved one of the intricate territorial arrangements of south-eastern Arabia.

Petroleum Development Oman began commercial oil production in August 1967, three years after reserves were discovered near Fahud in the western desert. Oil revenue subsequently transformed government finances and funded decades of infrastructure development.

A separatist insurgency backed by South Yemen took hold in Dhofar province from 1964. Sultan Qaboos, with British and Iranian military support, defeated the rebels by 1975, ending the biggest internal conflict of the period.

On 11 December 1963 the General Assembly created a committee to study the 'Question of Oman' after exiled Imamate partisans took their case to the Arab League and United Nations. Resolutions in 1965, 1966 and 1967 called on Britain to end repressive action and its control over Oman and affirmed Omani rights to self-determination.

On 27 January 1959 Sultanate troops seized the Jebel Akhdar plateau, after Colonel David Smiley had isolated the mountain and found a route via Wadi Bani Kharus. Imam Ghalib, Talib and Sulaiman escaped to Saudi Arabia, and the Imamate of Oman was abolished.

On 8 September 1958 Pakistan bought Gwadar, long held by Oman since sovereignty was granted to Imam Sultan, for US$3 million; it then became a tehsil of Makran district. The sale ended the last Omani possession on the Asian mainland.
