Prehistory in
Ad Dhahirah, built in the 3rd millennium
BCE and a
UNESCO World Heritage Site sites in Oman Al Aybut Al Awal, in the
Dhofar Governorate of Oman, a site was discovered in 2011 containing more than 100 surface scatters of stone tools, belonging to a regionally specific African
lithic industry—the late
Nubian Complex—known previously only from the northeast and
Horn of Africa. Two optically stimulated luminescence age estimates place the Arabian Nubian Complex at 106,000 years old. This supports the proposition that early human populations moved from Africa into Arabia during the
Late Pleistocene. In recent years surveys have uncovered Palaeolithic and Neolithic sites on the eastern coast. Main Palaeolithic sites include Saiwan-Ghunaim in the Barr al-Hikman. Archaeological remains are particularly numerous for the Bronze Age
Umm an-Nar and
Wadi Suq periods. At the archaeological sites of Bat, Al-Janah, and Al-Ayn wheel-turned pottery, hand-made stone vessels, metals industry artifacts, and monumental architecture have been preserved.
Ancient history Magan civilisation Sumerian tablets referred to Oman as "
Magan" and in the
Akkadian language "Makan", a name that links Oman's ancient copper resources. This is a clear reference to the Magan civilisation, an ancient region in what is now modern day Oman and
United Arab Emirates, which was referred to in
Sumerian
cuneiform texts of around 2300 BCE and existed until 550 BCE as a source of
copper and
diorite for
Mesopotamia.
Iron Age to pre-Islamic period There is considerable agreement in sources that
frankincense was used by traders in 1500 BCE. The
Land of Frankincense, a
UNESCO World Heritage Site, dramatically illustrates that the incense constituted testimony to
South Arabian civilisations. During the 8th century BCE, it is believed that the Yaarub, the descendant of
Qahtan, ruled the entire region of Yemen, including Oman. Wathil bin Himyar bin
Abd-Shams (Saba) bin Yashjub (
Yaman) bin Yarub bin
Qahtan later ruled Oman. believed by virtue of oral history that in the 6th century BCE, the
Achaemenids exerted control over the Omani peninsula, most likely ruling from a coastal centre such as
Suhar. The northern half of Oman was presumably was part of the
Maka satrapy of the Persian
Achaemenid Empire. By the time of the
conquests of Alexander the Great, the satrapy may have existed in some form and Alexander is said to have stayed in
Purush, its capital, perhaps near
Bam, in
Kerman province. Central Oman has its own indigenous Samad Late Iron Age cultural assemblage named eponymously from
Samad al-Shan. In the northern part of the Oman Peninsula the
Recent Pre-Islamic Period begins in the 3rd century BCE and extends into the 3rd century CE. Whether or not Persians brought south-eastern Arabia under their control is a moot point, since the lack of Persian archeological finds speak against this belief.
Armand-Pierre Caussin de Perceval suggests that Shammir bin Wathil bin Himyar recognised the authority of
Cyrus the Great over Oman in 536 BCE. The Omani Kingdom was subdued by the
Sasanian Empire's forces under
Vahrez during the
Aksumite–Persian wars. The 4,000-strong Sasanian garrison was headquartered at Jamsetjerd/Jamshedgird (modern Jebel Gharabeh, also known as Felej al-Sook)
Azd tribal migration Over centuries, From the 2nd half of the 1st millennium BCE, waves of Semitic speaking peoples migrated from central and western Arabia to the east. The most important of these migrating tribes are known as
Azd. they made a living by fishing, farming, herding or stock breeding. Further, many present-day Omani families trace their ancestral roots to other parts of Arabia. Arab migration to Oman started from northern-western and south-western Arabia and those who chose to settle had to compete with the indigenous population for the best arable land. When Arab tribes started to migrate to Oman, there were two distinct groups. One group, a segment of the
Azd tribe migrated from
Yemen in 120 According to Al-Kalbi, Malik bin Fahm was the first settler of Alazd. He is said to have first settled in
Qalhat. By this account, Malik, with an armed force of more than 6000 men and horses, fought against the
Marzban, who served an ambiguously named Persian king in the battle of Salut in Oman and eventually defeated the Persian forces. This account is, however, semi-legendary and seems to condense multiple centuries of migration and conflict as well as an amalgamation of various traditions from not only the Arab tribes but also the region's original inhabitants. During the 7th century CE, Omanis came in contact with and accepted
Islam. The conversion of Omanis to Islam is ascribed to
Amr ibn al-As, who was sent by the Islamic prophet
Muhammad during the
Expedition of Zaid ibn Haritha (Hisma). Amr was dispatched to meet with Jaifer and Abd, the sons of Julanda who ruled Oman. They appear to have readily embraced Islam.
Imamate of Oman Omani
Azd used to travel to
Basra for trade, which was a centre of Islam, during the
Umayyad empire. Omani Azd were granted a section of Basra, where they could settle and attend to their needs. Many of the Omani Azd who settled in Basra became wealthy merchants and, under their leader
al-Muhallab ibn Abi Sufra, started to expand their influence of power eastwards towards
Khorasan.
Ibadism originated in Basra through its founder,
Abd Allah ibn Ibad, as a moderate branch of the Kharijites, an Islamic sect that split from the
Muhakkima. These groups initially supported Imam
Ali during the
First Fitna but turned away after rejecting arbitration at the
Battle of Siffin in AD 657. around the year 650; the Omani Azd in Iraq would subsequently adopt this as their predominant faith. Later,
al-Hajjaj, the governor of Iraq, came into conflict with the Ibadis, which forced them back to Oman. Among those who returned was the scholar
Jaber bin Zaid. His return (and the return of many other scholars) greatly enhanced the Ibadhi movement in Oman. , a UNESCO World Heritage site, was built between 12th and 15th c. by the
Nabhani dynasty. The first elective
Imamate of Oman is believed to have been established shortly after the fall of the
Umayyad Dynasty in 750/755 CE, when Janaħ bin ʕibadah Alħinnawi was elected. Other scholars claim that Janaħ bin Ibadah served as a
Wāli (governor) under the
Umayyad dynasty (and later ratified the Imamate), and that Julanda bin Masud was the first elected Imam of Oman, in 751 CE. The first Imamate reached its peak power in the ninth century CE. The authority of the Imams started to decline due to power struggles, the constant interventions of Abbasid, and the rise of the
Seljuk Empire. The Nabhanis ruled as
muluk, or kings, while the Imams were reduced to largely symbolic significance. The capital of the dynasty was
Bahla. The Banu Nabhan controlled the trade in frankincense on the overland route via
Sohar to the
Yabrin oasis, and then north to Bahrain, Baghdad and Damascus. The mango-tree was introduced to Oman during the time of Nabhani dynasty, by ElFellah bin Muhsin. The Nabhani dynasty started to deteriorate in 1507 when Portuguese colonisers captured the coastal city of
Muscat, and gradually extended their control along the coast up to
Sohar in the north and down to
Sur in the southeast. Other historians argue that the Nabhani dynasty ended earlier in 1435 CE when conflicts between the dynasty and Alhinawis arose, which led to the restoration of the elective Imamate. In need of an outpost to protect their sea lanes, the Portuguese built up and fortified Muscat. Remnants of Portuguese architectural style still exist. Later, several more Omani cities were colonised in the early 16th century by the Portuguese, to control the entrances of the
Persian Gulf and trade in the region as part of a web of fortresses in the region, from
Basra to
Hormuz Island. At the
Battle of the Gulf of Oman, the Portuguese decisively routed an Ottoman fleet. Later in the 17th century, using its bases in Oman, Portugal engaged in the
largest naval battle ever fought in the Persian Gulf. The
Portuguese force fought against a combined armada of the
Dutch East India Company (VOC) and
English East India Company supported by the Safavid empire. The result of the battle was a draw but it resulted in the loss of Portuguese influence in the Gulf.
Yaruba dynasty (1624–1744) , Oman became one of the powers in the western Indian Ocean from 1698 onwards. During the 17th century, the Omanis were reunited by the
Yaruba Imams. Nasir bin Murshid became the first Yaarubah Imam in 1624, when he was elected in Rustaq. Imam Nasir and his successor succeeded in the 1650s in expelling the Portuguese from their coastal domains in Oman. The Omanis over time established a maritime empire that pursued the Portuguese and expelled them from all their possessions in East Africa, which were then incorporated into the Omani domains. To capture Zanzibar
Saif bin Sultan, the
Imam of Oman, pressed down the
Swahili Coast. A major obstacle to his progress was
Fort Jesus, housing the garrison of a Portuguese settlement at
Mombasa. After a two-year siege, the fort fell to Imam Saif bin Sultan in 1698. Saif bin Sultan occupied Bahrain in 1700. The rivalry within the house of Yaruba over power after the death of Imam Sultan in 1718 weakened the dynasty. With the power of the Yaruba Dynasty dwindling, Imam Saif bin Sultan II eventually asked for help against his rivals from
Nader Shah of Persia. A Persian force arrived in March 1737 to aid Saif. From their base at Julfar, the Persian forces eventually rebelled against the Yaruba in 1743. The Persian empire then tried to take possession of the coast of Oman until 1747.
18th and 19th centuries in
Zanzibar, which was once Oman's capital and residence of its sultans After the Omanis expelled the
Persians,
Ahmed bin Sa'id Albusaidi became the elected Imam of Oman on 20 November 1744, with
Rustaq serving as the capital. His dynasty, the Al Bu Said, continues to rule Oman into the year 2026. Since the revival of the Imamate, the Omanis continued with the elective system but, provided that the person is deemed qualified, gave preference to a member of the ruling family. Following Imam Ahmed's death in 1783, his son,
Said bin Ahmed, became the elected Imam. Said's son,
Hamed bin Said, overthrew the governor of Muscat and soon obtained the possession of most of the fortresses in the region, giving himself the title of "Seyyid". Afterwards, Seyyid
Sultan bin Ahmed, the uncle of Seyyid Hamed, took over power. Sultan's son, Seyyid
Said bin Sultan, succeeded him. During the entire 19th century, in addition to Imam Said bin Ahmed, who retained the title until he died in 1803,
Azzan bin Qais was the only elected Imam of Oman. His rule started in 1868. However, the British refused to accept Imam Azzan as a ruler, as he was viewed as inimical to their interests. This view played an instrumental role in supporting the deposition of Imam Azzan in 1871 by his cousin,
Sayyid Turki, a son of the late Sayyid Said bin Sultan and brother of
Sultan Barghash of Zanzibar, who Britain deemed to be more acceptable. Oman's Imam Sultan, defeated ruler of Muscat, was granted sovereignty over
Gwadar, an area of modern-day Pakistan.
British protectorate status The
British Empire was keen to dominate southeast Arabia to stifle the growing power of other European states and to curb the Omani maritime power that grew during the 17th century. In 1798, the first treaty between the British
East India Company and the Albusaidi dynasty was signed by Sayyid Sultan bin Ahmed. The treaty aimed to block commercial competition of the French and the Dutch as well as obtain a concession to build a British factory at
Bandar Abbas. A second treaty was signed in 1800, which stipulated that a British representative shall reside at the port of Muscat and manage all external affairs with other states. The British government achieved predominating control over Muscat, which, for the most part, impeded competition from other nations. Between 1862 and 1892, the Political Residents,
Lewis Pelly and Edward Ross, played an instrumental role in securing British supremacy over the Persian Gulf and Muscat by a system of indirect governance. The Sultanate thus came
de facto under the British sphere.
Treaty of Seeb The
Hajar Mountains, of which the
Jebel Akhdar is a part, separate the country into two distinct regions: the interior, and the coastal area dominated by the capital, Muscat. The British imperial development over Muscat and Oman during the 19th century led to the renewed revival of the cause of the Imamate in the interior of Oman, which has appeared in cycles for more than 1,200 years in Oman. In 1913, Imam Salim Alkharusi instigated an anti-Muscat rebellion that lasted until 1920 when the Sultanate established peace with the Imamate by signing the
Treaty of Seeb. The treaty was brokered by Britain, which had no economic interest in the interior of Oman during that point of time. The treaty granted autonomous rule to the Imamate in the interior of Oman and recognised the sovereignty of the coast of Oman, the
Sultanate of Muscat. In 1920, Imam Salim Alkharusi died and Muhammad Alkhalili was elected. On 31 July 1928, the
Red Line Agreement was signed between Anglo-Persian Company (later renamed British Petroleum), Royal Dutch/Shell, Compagnie Française des Pétroles (later renamed Total), Near East Development Corporation (later renamed ExxonMobil) and Calouste Gulbenkian (an Armenian businessman) to collectively produce oil in the post-
Ottoman Empire region, which included the Arabian peninsula, with each of the four major companies holding 23.75 percent of the shares while
Calouste Gulbenkian held the remaining 5 percent shares. The agreement stipulated that none of the signatories was allowed to pursue the establishment of oil concessions within the agreed on area without including all other stakeholders. In 1929, the members of the agreement established
Iraq Petroleum Company (IPC). On 13 November 1931, Sultan Taimur bin Faisal abdicated.
Reign of Sultan Said (1932–1970) ruled from 1932 to 1970
Said bin Taimur became the sultan of Muscat officially on 10 February 1932. The rule of sultan Said, a very complex character, was backed by the British government, and has been characterised as being
feudal,
reactionary and isolationist. In 1937, an agreement between the sultan and
Iraq Petroleum Company (IPC), a consortium of oil companies that was 23.75% British owned, was signed to grant oil concessions to IPC. After failing to discover oil in the Sultanate, IPC was intensely interested in some promising geological formations near
Fahud, an area located within the Imamate. IPC offered financial support to the sultan to raise an armed force against any potential resistance by the Imamate. Upon the outbreak of
World War II, the sultan of Oman declared war on Germany on September 10, 1939. Gwadar then became a
tehsil in the Makran district.
Jebel Akhdar War Sultan Said bin Taimur expressed his interest in occupying the Imamate right after the death of Imam Alkhalili, thus taking advantage of any potential instability that might occur within the Imamate when elections were due, to the British government. The British political agent in Muscat believed that the only method of gaining access to the oil reserves in the interior was by assisting the sultan in taking over the Imamate. In 1946, the British government offered arms and ammunition, auxiliary supplies and officers to prepare the sultan to attack the interior of Oman. In May 1954, Imam Alkhalili died and
Ghalib Alhinai was elected Imam. Relations between the Sultan Said bin Taimur, and Imam Ghalib Alhinai frayed over their dispute about oil concessions. In December 1955, Sultan Said bin Taimur sent troops of the Muscat and Oman Field Force to occupy the main centres in Oman, including
Nizwa, the capital of the Imamate of Oman, and
Ibri. The Omanis in the interior led by Imam Ghalib Alhinai, Talib Alhinai, the brother of the Imam and the Wali (governor) of Rustaq, and Suleiman bin Hamyar, who was the Wali (governor) of Jebel Akhdar, defended the Imamate in the
Jebel Akhdar War against British-backed attacks by the Sultanate. In July 1957, the Sultan's forces were withdrawing, but they were repeatedly ambushed, sustaining heavy casualties. The Imamate's forces retreated to the inaccessible
Jebel Akhdar. On 27 January 1959, the Sultanate's forces occupied the mountain in a surprise operation. The exiled partisans of the now abolished Imamate of Oman presented the case of Oman to the
Arab League and the United Nations. On 11 December 1963, the UN General Assembly decided to establish an Ad-Hoc Committee on Oman to study the 'Question of Oman' and report back to the General Assembly. The UN General Assembly adopted the 'Question of Oman' resolution in 1965, 1966 and again in 1967 that called upon the British government to cease all repressive action against the locals, end British control over Oman and reaffirmed the inalienable right of the Omani people to self-determination and independence.
Dhofar War In the
Dhofar War, which began in 1963, pro-
Soviet forces were pitted against government troops. As the rebellion threatened the Sultan's control of
Dhofar, Sultan Said bin Taimur was deposed in a
bloodless coup in 1970 by his son
Qaboos bin Said with
British support. Qaboos expanded the
Sultan of Oman's Armed Forces, modernised the state's administration and introduced social reforms. The uprising was finally put down in 1976 with the help of forces from Jordan, Saudi Arabia, Iran, Pakistan and Britain.
Modern history (1970–present) , whose reign saw a rise in living standards and development, the
abolition of slavery, the end of the
Dhofar Rebellion, and the promulgation of Oman's constitution. After deposing his father in 1970,
Sultan Qaboos opened up the country, removed "Muscat and" from the country's name, embarked on economic reforms, and followed a policy of modernisation marked by increased spending on health, education and welfare. Saudi Arabia invested in the development of the Omani education system, sending Saudi teachers on its own expense.
Slavery, once a cornerstone of the country's trade and development, was outlawed in 1970. In 1971, Oman joined the United Nations, along with Bahrain, Qatar and the United Arab Emirates. In 1981, Oman became a founding member of the six-nation
Gulf Cooperation Council. Political reforms were eventually introduced. The country adopted its present
national flag in 1995, resembling the previous flag but with a thicker stripe. In 1997, a royal decree was issued granting women the right to vote, and stand for election to the Majlis al-Shura, the
Consultative Assembly of Oman. Two women were duly elected to the body. In 2002, voting rights were extended to all citizens over the age of 21, and the first elections to the Consultative Assembly under the new rules were held in 2003. In 2004, the Sultan appointed Oman's first female minister with portfolio,
Sheikha Aisha bint Khalfan bin Jameel al-Sayabiyah, to the post of National Authority for Industrial Craftsmanship. Despite these changes, there was little change to the actual political makeup of the government. The Sultan continued to rule by decree. Nearly 100 suspected Islamists were arrested in 2005 and 31 people were convicted of trying to overthrow the government. They were ultimately pardoned in June of the same year. Inspired by the
Arab Spring uprisings that were taking place throughout the region,
protests occurred in Oman during the early months of 2011. While they did not call for the ousting of the regime, demonstrators demanded political reforms, improved living conditions and the creation of more jobs. They were dispersed by riot police in February 2011. Sultan Qaboos reacted by promising jobs and benefits. In October 2011, elections were held to the Consultative Assembly, to which Sultan Qaboos promised greater powers. The following year, the government began a crackdown on internet criticism. In September 2012, trials began of 'activists' accused of posting "abusive and provocative" criticism of the government online. Six were given jail terms. In 2013, Oman achieved its status as the elimination of
malaria diagnoses, according to the
World Health Organisation (WHO). Qaboos, at the time the Arab world's longest-serving ruler, died on 10 January 2020. He was succeeded by his first cousin
Haitham bin Tariq. On 12 January 2021, Haitham named his eldest son,
Theyazin bin Haitham, as the country's first
crown prince and heir to the throne with an amendment to the
Basic Statute. == Geography ==
