Oman is a sultanate on the southeastern coast of the Arabian Peninsula, bordered by Saudi Arabia, the United Arab Emirates, and Yemen, with coastlines on the Arabian Sea and the Gulf of Oman.

Where Is Oman Located?

Oman sits on the southeastern edge of the Arabian Peninsula, where it has traded across the Indian Ocean for millennia. The country covers about 309,500 square kilometers (119,499 square miles), roughly the size of Kansas or Italy, and borders Saudi Arabia to the west, the United Arab Emirates to the northwest, and Yemen to the southwest. Its capital is Muscat, a Gulf of Oman port city that has been the political center of the country since the 18th century.

One feature sets Oman apart on the map: the Musandam Peninsula, a rocky, fjord-lined exclave on the Strait of Hormuz, cut off from the rest of the country by a strip of UAE territory. This narrow strait between Musandam and Iran is one of the world’s most important maritime chokepoints for oil shipping, giving Oman an outsized strategic role relative to its size.

Inland, the terrain shifts fast. The Al Hajar Mountains, which run parallel to the northern coast, reach elevations of more than 3,000 meters (10,000 feet), the highest range in the eastern Arabian Peninsula. South of them lie gravel plains and the edge of the Rub’ al Khali, or Empty Quarter, one of the largest sand deserts on Earth. The Wahiba Sands dune field in the east and the Dhofar region in the far south, which catches a seasonal monsoon unlike almost anywhere else in Arabia, round out a geography more varied than the country’s desert reputation suggests.

Water scarcity shaped Omani life long before modern plumbing. The aflaj, a network of gravity-fed channels that carry water from underground sources and mountain springs to farms and towns, still supplies an estimated 30 to 50 percent of the water used in Oman today. Some systems may date to around 500 CE, with evidence of irrigation in the region reaching back to 2500 BCE, according to UNESCO’s documentation of the Aflaj Irrigation Systems of Oman, inscribed as a World Heritage site in 2006.

A Brief History of Oman

Ancient Trade and the Rise of Ibadi Islam

Archaeological evidence places organized settlement and trade in Oman back to roughly the third millennium BCE, when the region, likely part of the ancient land known as Magan, traded copper with Mesopotamia. Arab tribes migrated into the area from southern Arabia around the second century CE, and Islam arrived in the seventh century. By the mid-eighth century, Oman had adopted Ibadi Islam, a branch of Islam rooted in the early Kharijite movement but without its more extreme positions, which established an elected imamate rather than a hereditary one. Oman remains the only country where Ibadi Muslims form the majority of the population, a fact that still shapes its religious and political culture.

Omani sailors built an extensive Indian Ocean trading network, reportedly reaching China by the 15th century, but that maritime reach also made Oman a target: Portuguese forces sacked Muscat in 1507 and held key ports for roughly 150 years. The Ya’rubid dynasty retook Muscat in 1650 and built a maritime empire into the Persian Gulf and East Africa, before succession disputes triggered civil war in the early 18th century.

The Al Said Dynasty and Modern Oman

Out of that instability, and after a brief Persian invasion, Ahmad bin Said Al Busaidi united the country and founded the Al Said dynasty in 1744, a line that still rules Oman today. In the 19th century, under Sultan Said bin Sultan (reigned 1804 to 1856), Omani influence reached East Africa, with Zanzibar becoming a second center of power built on the clove trade; an Omani ship reached the United States in 1840, one of the earliest direct trade contacts between the Gulf and America.

Decades of relative isolation followed before a 1970 palace coup replaced Sultan Said bin Taimur with his son, Qaboos bin Said. Qaboos launched a rapid modernization program, using oil revenue to build schools, hospitals, and infrastructure largely absent under his father’s rule, while putting down a Yemeni-backed rebellion in Dhofar by 1975. He ruled for nearly five decades, issuing the Basic Statute of the State (the constitution) in 1996 and establishing the Council of Oman as a consultative body. When Qaboos died in January 2020 without a named heir, the ruling family’s council chose his cousin, Haitham bin Tariq, as sultan; Haitham has since pursued Oman Vision 2040, a plan to diversify the economy away from oil.

How Is Oman Governed, and What Drives Its Economy?

Oman is an absolute monarchy. Under the Basic Statute of the State, the sultan is head of state and supreme commander of the armed forces, governing with an appointed Council of Ministers. The legislature, the Council of Oman, has two chambers: the appointed Majlis A’Dawla (State Council) and the Majlis A’Shura (Consultative Council), whose 84 members are directly elected from Oman’s regional districts. The elected chamber can propose legislation, debate the budget, and question ministers, though ultimate authority stays with the sultan.

Oman’s economy has long depended on oil and gas exports, but the government has worked to reduce that reliance through Oman Vision 2040, a plan launched in 2020 around four pillars: people and society, economy and development, environment and sustainability, and governance. Projects tied to it include the Duqm Refinery, which opened in 2024 and has since grown to 255,000 barrels per day of capacity, and the Oman Future Fund, capitalized with two billion Omani rials to finance large projects and small and medium enterprises. Tourism, port logistics, and manufacturing are also being built up as non-oil pillars of the economy.

Omani Culture and People

Oman’s population reached about 5.4 million in 2025, with Omani citizens making up roughly 57 percent of that total and foreign residents the rest, according to figures from the National Centre for Statistics and Information. Arabic is the official language, and Ibadi Islam remains the majority religious tradition, alongside Sunni and Shia Muslim minorities and small communities of other faiths, mostly among expatriate workers.

Omani culture places a strong emphasis on hospitality, tribal and family ties, and craftsmanship rooted in the country’s maritime and desert past: dhow shipbuilding, silver jewelry, and the curved khanjar dagger worn as a national symbol are among its most recognizable traditions. Oman is also home to five UNESCO World Heritage sites: Bahla Fort, the archaeological sites of Bat, Al-Khutm and Al-Ayn, the Land of Frankincense, the Aflaj Irrigation Systems, and the ancient port city of Qalhat, a physical record of the trade and settlement that shaped the country over thousands of years.

What Is Oman Known For?

Globally, Oman is most closely associated with frankincense. The aromatic resin, harvested from Boswellia sacra trees that grow almost exclusively in Dhofar, was one of the most valuable commodities of the ancient and medieval world, traded along routes linking Arabia to the Mediterranean, Mesopotamia, India, and China. UNESCO’s Land of Frankincense site, which includes the frankincense groves of Wadi Dawkah and the ancient ports of Khor Rori and Al-Baleed, documents that trade’s scale and reach.

Oman is also known for the Sultan Qaboos Grand Mosque in Muscat, widely regarded as its most recognizable landmark and one of the largest mosques in the Arabian Peninsula. Built over six years following an international design competition, the complex covers about 416,000 square meters and can hold roughly 20,000 worshippers, with the main prayer hall alone seating 6,500 beneath a central dome 50 meters high. Its prayer hall carpet, woven from about 1.7 billion knots over 27 months, covers 4,200 square meters and weighs 21 tons, one of the largest single-piece carpets ever produced. Beyond the mosque, Oman’s forts, mountain villages, and the dunes of the Wahiba Sands and fjords of Musandam have made the country an increasingly prominent name in Arabian Peninsula heritage and scenery.

Why Oman Matters Globally

Oman’s significance extends beyond its landmarks. Its position at the mouth of the Strait of Hormuz gives it direct influence over one of the world’s most important energy shipping routes, and it has used that position, along with a foreign policy built on neutrality, to become one of the Middle East’s most consistent diplomatic intermediaries. Scholars studying its foreign relations describe this as a deliberate strategy of “niche diplomacy,” in which a smaller state builds influence through mediation rather than military or economic weight. Oman hosted the secret US-Iran talks between 2013 and 2015 that helped produce the Iran nuclear deal, has worked since 2015 to secure prisoner releases and support ceasefire efforts in Yemen’s civil war without joining the Saudi-led coalition there, and hosted early Saudi-Iran talks that preceded their 2023 rapprochement. That combination of geography, dynastic continuity, and a distinct religious identity gives Oman an influence in regional affairs disproportionate to its size.
