Bahrain, officially the Kingdom of Bahrain, is an island country in the eastern part of Arabian Peninsula in West Asia. Situated near the western shore of the Persian Gulf, the country comprises a small archipelago of 33 natural islands and an additional 50 artificial islands, centered on Bahrain Island, which makes up around 80 percent of the country's landmass. Bahrain is situated between Qatar and the northeastern coast of Saudi Arabia, to which it is connected by the King Fahd Causeway. The population is 1,588,670 as of 2024, of whom 739,736 (46.6% of the population) are Bahraini nationals, and 848,934 are expatriates (53.4% of the population). Bahrain spans some 760 square kilometres (290 sq mi) and is the third-smallest nation in Asia after Maldives and Singapore. The capital and largest city is Manama.
The area that straddles the present-day territory of Bahrain was once the site of the ancient Dilmun civilisation. It has been famed since antiquity for its pearl fisheries, which were considered the best in the world into the 19th century. Bahrain was one of the earliest areas to be influenced by Islam, during the lifetime of Muhammad in 628. Following a period of Arab rule, Bahrain was ruled by the Portuguese Empire from 1521 until 1602, when they were expelled by Shah Abbas the Great of the Safavid Iran. In 1783, the Bani Utbah and allied tribes captured Bahrain from Nasr Al-Madhkur. It has since been ruled by the Al Khalifa royal family, with Ahmed al Fateh as Bahrain's first hakim.
In the late 19th century, following successive treaties with the British, Bahrain became a protectorate of the United Kingdom. In 1971, it declared independence. Formerly an emirate, Bahrain was declared a semi-constitutional monarchy in 2002, and Article 2 of the constitution made sharia a principal source for legislation. In 2011, the country experienced protests inspired by the regional Arab Spring. The ruling Sunni Muslim Al Khalifa royal family has been criticised for violating the human rights of groups including dissidents, political opposition figures, and its Shia Muslim population.
Bahrain is known as one of the first post-oil economies in the Persian Gulf, the result of decades of investing in the banking and tourism sectors. Many of the world's largest financial institutions have a presence in Manama, but oil revenues still constitute a significant part of its government budget. It is recognised by the World Bank as a high-income economy. Bahrain is a member of the United Nations, the Non-Aligned Movement, the Arab League, the Organisation of Islamic Cooperation, and the Gulf Cooperation Council. It is a Dialogue partner of the Shanghai Cooperation Organization.
Etymology
Bahrain is the dual form of the Arabic word Bahr (meaning "sea"), so al-Bahrayn originally means "the two seas". However, the name has been lexicalised as a feminine proper noun and does not follow the grammatical rules for duals; thus its form is always Bahrayn and never Bahrān, the expected nominative form. Endings are added to the word with no changes, as in the name of the national anthem Bahraynunā ("our Bahrain") or the demonym Bahraynī. The medieval grammarian al-Jawahari commented on this, saying that the more formally correct term Bahrī (lit. 'belonging to the sea') would have been misunderstood and so was unused.
It remains disputed which "two seas" the name Bahrayn originally refers to. The term appears five times in the Quran but does not refer to the modern island—originally known to the Arabs as Awal. Today, Bahrain's "two seas" are generally taken to be the bay east and west of the island, the seas north and south of the island, or the salt and fresh water present above and below the ground. In addition to wells, there are areas of the sea north of Bahrain where fresh water bubbles up in the middle of the saltwater as noted by visitors since antiquity. An alternative theory concerning Bahrain's toponymy is offered by the al-Ahsa region, which suggests that the two seas were the "Great Green Ocean" (the Persian Gulf) and Al-Asfar Lake on the Arabian mainland.
Until the late Middle Ages, "Bahrain" referred to the region of Eastern Arabia that included southern Iraq, Kuwait, Al-Hasa, Qatif, and Bahrain. The region stretched from Basra in Iraq to the Strait of Hormuz in Oman. This was Iqlīm al-Bahrayn's "Bahrayn Province". When the term "Bahrain" began to refer solely to the Awal archipelago is unknown. The entire coastal strip of Eastern Arabia was known as "Bahrain" for a millennium. The island and kingdom were also commonly spelled Bahrein.
History
Antiquity
Bahrain was home to Dilmun, an important Bronze Age trade centre linking Mesopotamia and the Indus Valley. Bahrain was later ruled by the Sumerians and Babylonians. From the 6th to 3rd century BC, Bahrain was part of the Achaemenid Empire. By about 250 BC, Parthia brought the Persian Gulf under its control and extended its influence as far as Oman. The Parthians established garrisons along the southern coast of the Persian Gulf to control trade routes.
During the classical era, Bahrain was referred to by the ancient Greeks as Tylos, the centre of pearl trading, when the Greek admiral Nearchus serving under Alexander landed on Bahrain. Nearchus is believed to have been the first of Alexander's commanders to visit the island, and he found a verdant land that was part of a wide trading network; he recorded: "That on the island of Tylos, situated in the Persian Gulf, are large plantations of cotton trees, from which are manufactured clothes called sindones, of strongly differing degrees of value, some being costly, others less expensive. The use of these is not confined to India, but extends to Arabia."
The Greek philosopher and a botanist Theophrastus states that much of Bahrain was covered by these cotton trees and that Bahrain was famous for exporting walking canes engraved with emblems that were customarily carried in Babylon. Alexander had planned to settle Greek colonists in Bahrain, and although it is not clear that this happened on the scale he envisaged, Bahrain became very much part of the Hellenised world: the language of the upper classes was Greek, with Aramaic in everyday use. Local coinage shows a seated Zeus, who may have been worshipped there as a syncretised form of the Arabian sun-god Shams. Tylos was also the site of Greek athletic contests.
The Greek historian Strabo believed the Phoenicians originated from Bahrain. Herodotus also believed that the homeland of the Phoenicians was Bahrain. This theory was accepted by the 19th-century German classicist Arnold Heeren who said "In the Greek geographers, for instance, we read of two islands, named Tyrus or Tylos, and Aradus, which boasted that they were the mother country of the Phoenicians, and exhibited relics of Phoenician temples." The people of Tyre in particular have long maintained Persian Gulf origins, and the similarity in the words "Tylos" and "Tyre" has been commented upon. However, there is little evidence of any human settlement at all on Bahrain during the time when such migration had supposedly taken place.
The name Tylos is thought to be a Hellenisation of the Semitic Tilmun (from Dilmun). The term Tylos was commonly used for the islands until Ptolemy's Geographia when the inhabitants are referred to as Thilouanoi. Some place names in Bahrain go back to the Tylos era; for instance the name of Arad, a residential suburb of Muharraq, is believed to originate from "Arados", the ancient Greek name for Muharraq.
In the 3rd century, Ardashir I, the first ruler of the Sassanid dynasty, marched on Oman and Bahrain, where he defeated Sanatruq the ruler of Bahrain.
Bahrain was the site of worship of an ox deity called Awal (Arabic: اوال). Worshipers built a large statue to Awal in Muharraq, although it has now been lost. For many centuries after Tylos, Bahrain was known as Awal. By the 5th century, Bahrain became a centre for Nestorian Christianity, with the village Samahij as the seat of bishops. In 410, according to the Oriental Syriac Church synodal records, a bishop named Batai was excommunicated from the church in Bahrain. As a sect, the Nestorians were often persecuted as heretics by the Byzantine Empire, but Bahrain was outside the empire's control, offering some safety. The names of several Muharraq villages today reflect Bahrain's Christian legacy, with Al Dair meaning "the monastery".
Bahrain's pre-Muslim population consisted of Christian Arabs (mostly Abd al-Qays), Persians (Zoroastrians), Jews, and Aramaic-speaking agriculturalists. According to Robert Bertram Serjeant, the Baharna may be the Arabised "descendants of converts from the original population of Christians (Aramaeans), Jews and Persians inhabiting the island and cultivated coastal provinces of Eastern Arabia at the time of the Muslim conquest". The sedentary people of pre-Muslim Bahrain were Aramaic speakers and to some degree Persian speakers, while Syriac functioned as a liturgical language.
Arrival of Islam
Muhammad's first interaction with the people of Bahrain was the Al Kudr Invasion. Muhammad ordered a surprise attack on the Banu Salim tribe for plotting to attack Medina. He had received news that some tribes were assembling an army in Bahrain and preparing to attack the mainland, but the tribesmen retreated when they learned Muhammad was leading an army to do battle with them.
Traditional Muslim accounts state that Al-Ala'a Al-Hadrami was sent as an envoy during the Expedition of Zayd ibn Harithah (Hisma) to the Bahrain region by Muhammad in AD 628 and that Munzir ibn Sawa Al Tamimi, the local ruler, responded to his mission and converted the entire area.
Middle Ages
In 899, the Qarmatians, a millenarian Ismaili Muslim sect, seized Bahrain, seeking to create a utopian society based on reason and redistribution of property among initiates. Thereafter, the Qarmatians demanded tribute from the caliph in Baghdad, and in 930 sacked Mecca, bringing the sacred Black Stone back to their base in Ahsa, in medieval Bahrain, for ransom. According to historian Al-Juwayni, the stone was returned 22 years later in 951 under mysterious circumstances. Wrapped in a sack, it was thrown into the Great Mosque of Kufa in Iraq, accompanied by a note saying "By command we took it, and by command, we have brought it back." The theft and removal of the Black Stone caused it to break into seven pieces.
Following their defeat in 976 by the Abbasids, the Qarmatians were overthrown by the Arab Uyunid dynasty of al-Hasa, who took over the entire Bahrain region in 1076. The Uyunids controlled Bahrain until 1235, when the archipelago was briefly occupied by the Persian ruler of Fars. In 1253, the Usfurids brought down the Uyunid dynasty, thereby gaining control over eastern Arabia, including the islands of Bahrain.
In 1330, the archipelago became a tributary state of the rulers of Hormuz. Locally, the islands were controlled by the Shia Jarwanid dynasty of Qatif.
In the mid-15th century, the archipelago came under the rule of the Jabrids, a Bedouin dynasty also based in Al-Ahsa that ruled most of eastern Arabia.
Portuguese and early modern era
In 1521, the Portuguese allied with Hormuz and seized Bahrain from the Jabrid ruler Muqrin ibn Zamil, who was killed during the takeover. Portuguese rule lasted for around 80 years, during which time they depended mainly on Sunni Persian governors. The Portuguese were expelled from the islands in 1602 by Abbas I of the Safavid Iran, which gave impetus to Shia Islam.
For the next two centuries, Persian rulers retained control of the archipelago, interrupted by the 1717 and 1738 invasions of the Ibadis of Oman. During most of this period, they resorted to governing Bahrain indirectly, either through the city of Bushehr or through immigrant Sunni Arab clans. The latter were tribes returning to the Arabian side of the Persian Gulf from Persian territories in the north who were known as Huwala. In 1753, the Huwala clan of Nasr Al-Madhkur invaded Bahrain on behalf of the Iranian Zand leader Karim Khan Zand and restored direct Iranian rule.
In 1783, Al-Madhkur lost the islands of Bahrain following his defeat by the Bani Utbah clan and allied tribes at the 1782 Battle of Zubarah. Bahrain was not new territory to the Bani Utbah; they had been a presence there since the 17th century. During that time, they started purchasing date palm gardens in Bahrain; a document shows that 81 years before the arrival of the Al Khalifa, one of the sheikhs of the Al Bin Ali tribe (an offshoot of the Bani Utbah) had bought a palm garden from Mariam bint Ahmed Al Sanadi in Sitra island.
The Al Bin Ali were the dominant group controlling the town of Zubarah on the Qatar peninsula, originally the centre of power of the Bani Utbah. After the Bani Utbah gained control of Bahrain, the Al Bin Ali had a practically independent status there as a self-governing tribe. They used a flag with four red and three white stripes, called the Al-Sulami flag in Bahrain, Qatar, Kuwait, and the Eastern province of the Kingdom of Saudi Arabia. Later, different Arab family clans and tribes from Qatar moved to Bahrain to settle after the fall of Nasr Al-Madhkur of Bushehr. These families included the House of Khalifa, Al-Ma'awdah, Al-Buainain, Al-Fadhil, Al-Kuwari, Al-Mannai, Al-Noaimi, Al-Rumaihi, Al-Sulaiti, Al-Sadah, Al-Thawadi and other families and tribes.
The House of Khalifa moved from Qatar to Bahrain in 1799. Originally, their ancestors were expelled from Umm Qasr in central Arabia by the Ottomans due to their predatory habits of preying on caravans in Basra and trading ships in Shatt al-Arab waterway until Turks expelled them to Kuwait in 1716, where they remained until 1766.
Around the 1760s, the Al Jalahma and House of Khalifa, both belonging to the Utub Federation, migrated to Zubarah in modern-day Qatar, leaving Al Sabah as the sole proprietors of Kuwait.
19th century and later
In the early 19th century, Bahrain was invaded by both the Omanis and the Al Sauds. In 1802 it was governed by a 12-year-old child, when the Omani ruler Sayyid Sultan installed his son, Salim, as governor in the Arad Fort. In 1816, the British political resident in the Persian Gulf, William Bruce, received a letter from the Sheikh of Bahrain who was concerned about a rumour that Britain would support an attack on the island by the Imam of Muscat. He sailed to Bahrain to reassure the Sheikh that this was not the case and drew up an informal agreement assuring the Sheikh that Britain would remain a neutral party.
In 1820, the Al Khalifa tribe were recognised by the United Kingdom as the rulers ("Al-Hakim" in Arabic) of Bahrain after signing a treaty relationship. However, ten years later they were forced to pay yearly tributes to Egypt despite seeking Persian and British protection.
In 1860, the Al Khalifas used the same tactic when the British tried to overpower Bahrain. Writing letters to the Persians and Ottomans, Al Khalifas agreed to place Bahrain under the latter's protection in March due to offering better conditions. Eventually, the Government of British India overpowered Bahrain when the Persians refused to protect it. Colonel Pelly signed a new treaty with Al Khalifas placing Bahrain under British rule and protection.
Following the Qatari–Bahraini War in 1868, British representatives signed another agreement with the Al Khalifas. It specified that the ruler could not dispose of any of his territories except to the United Kingdom and could not enter into relationships with any foreign government without British consent. In return the British promised to protect Bahrain from all aggression by sea and to lend support in case of land attack. More importantly the British promised to support the rule of the Al Khalifa in Bahrain, securing its unstable position as rulers of the country. Other agreements in 1880 and 1892 sealed the protectorate status of Bahrain to the British.
Unrest amongst the people of Bahrain began when Britain officially established complete dominance over the territory in 1892. The first revolt and widespread uprising took place in March 1895 against Sheikh Issa bin Ali, then ruler of Bahrain. Sheikh Issa was the first of the Al Khalifa to rule without Persian relations. Sir Arnold Wilson, Britain's representative in the Persian Gulf and author of The Persian Gulf, arrived in Bahrain from Muscat at this time. The uprising developed further with some protesters killed by British forces.
Before the development of the petroleum industry, the island was largely devoted to pearl fisheries and, as late as the 19th century, was considered to be the finest in the world. In 1903, German explorer Hermann Burchardt visited Bahrain and took many photographs of historical sites, including the old Qaṣr es-Sheikh, photos now stored at the Ethnological Museum of Berlin. Before the First World War, there were about 400 vessels hunting pearls and an annual export of more than £30,000.
In 1911, a group of Bahraini merchants demanded restrictions on the British influence in the country. The group's leaders were subsequently arrested and exiled to India. In 1923, the British introduced administrative reforms and replaced Sheikh Issa bin Ali with his son. Some clerical opponents and families, such as Al Dosari, left or were exiled to Saudi Arabia. Three years later the British placed the country under the de facto rule of Charles Belgrave who operated as an adviser to the ruler until 1957. Belgrave brought a number of reforms such as establishment of the country's first modern school in 1919 and the abolition of slavery in 1937. At the same time, the pearl diving industry developed at a rapid pace.
In 1927, Rezā Shāh, then Shah of Iran, demanded sovereignty over Bahrain in a letter to the League of Nations, a move that prompted Belgrave to undertake harsh measures including encouraging conflicts between Shia and Sunni Muslims to bring down the uprisings and limit the Iranian influence. Belgrave even went further by suggesting to rename the Persian Gulf to the "Arabian Gulf"; however, the proposal was refused by the British government. Britain's interest in Bahrain's development was motivated by concerns over Saudi and Iranian ambitions in the region.
The Bahrain Petroleum Company (Bapco), a subsidiary of the Standard Oil Company of California (Socal), discovered oil in 1932.
In the early 1930s, Bahrain Airport was developed. Imperial Airways flew there, including the Handley Page HP42 aircraft. Later in the same decade, the Bahrain Maritime Airport was established, for flying boats and seaplanes.
Bahrain participated in the Second World War on the Allied side, joining on 10 September 1939. On 19 October 1940, four Italian SM.82s bombers bombed Bahrain alongside Dhahran oilfields in Saudi Arabia, attacking Allied-operated oil refineries. Although minimal damage was caused in both locations, the attack forced the Allies to upgrade Bahrain's defences, an action which further stretched Allied military resources.
After World War II, increasing sentiments against British occupation spread throughout Arab countries and led to protests in Bahrain. The protests focused on the Jewish community. In 1948, following rising hostilities and looting, most members of Bahrain's Jewish community abandoned their properties and fled to Bombay, later settling in Israel (Pardes Hanna-Karkur) and the United Kingdom. As of 2008, 37 Jews remained in the country. In the 1950s, the National Union Committee, formed by reformists following sectarian clashes, demanded an elected popular assembly, removal of Belgrave and carried out a number of protests and general strikes. In 1965 a month-long uprising broke out after hundreds of workers at the Bahrain Petroleum Company were laid off.
Independence
On 15 August 1971, though the Shah of Iran was claiming historical sovereignty over Bahrain, he accepted a referendum held by the United Nations and eventually Bahrain declared independence and signed a new treaty of friendship with Britain. Bahrain joined the United Nations and the Arab League later in the year. The oil boom of the 1970s benefited Bahrain greatly, although the subsequent downturn hurt the economy. The country had already begun diversification of its economy and benefited further from the Lebanese Civil War in the 1970s and 1980s, when Bahrain replaced Beirut as the Middle East's financial hub after Lebanon's large banking sector was driven out of the country by the war.
In 1981, following the 1979 revolution in Iran, the Bahraini Shia population orchestrated a failed coup attempt under the auspices of a front organisation, the Islamic Front for the Liberation of Bahrain. The coup would have installed a Shia cleric exiled in Iran, Hujjatu l-Islām Hādī al-Mudarrisī, as supreme leader heading a theocratic government. In December 1994, a group of youths threw stones at female runners for running bare-legged during an international marathon. The resulting clash with police soon grew into civil unrest.
A popular uprising occurred between 1994 and 2000 in which leftists, liberals and fundamentalists joined forces. The event resulted in approximately forty deaths and ended after Hamad bin Isa Al Khalifa became the Emir of Bahrain in 1999. He instituted elections for parliament, gave women the right to vote, and released all political prisoners. A referendum on 14–15 February 2001 massively supported the National Action Charter. As part of the adoption of the National Action Charter on 14 February 2002, Bahrain changed its formal name from the State (dawla) of Bahrain to the Kingdom of Bahrain. At the same time, the title of the Head of State, Hamad bin Isa al-Khalifa, was changed from Emir to King.
The country participated in military action against the Taliban in October 2001 by deploying a frigate in the Arabian Sea for rescue and humanitarian operations. As a result, in November of that year, American president George W. Bush's administration designated Bahrain as a "major non-NATO ally". Bahrain opposed the 2003 American-led invasion of Iraq and had offered Saddam Hussein asylum in the days before the invasion. Relations improved with neighbouring Qatar after the border dispute over the Hawar Islands was resolved by the International Court of Justice in The Hague in 2001. Following the political liberalisation of the country, Bahrain negotiated a free trade agreement with America in 2004.
In 2005, Qal'at al-Bahrain, a fort and archaeological complex was inscribed as a UNESCO World Heritage Site.
2011 Bahraini protests
Inspired by the regional Arab Spring, Bahrain's Shia population started large protests against its Sunni rulers in early 2011. The government initially allowed protests following a pre-dawn raid on protesters camped in Pearl Roundabout. A month later it requested security assistance from Saudi Arabia and other Gulf Cooperation Council countries and declared a three-month state of emergency. The government then launched a crackdown on the opposition that included conducting thousands of arrests and systematic torture. Almost daily clashes between protesters and security forces led to dozens of deaths. Protests, sometimes staged by opposition parties, were ongoing. More than 80 civilians and 13 policemen have been killed as of March 2014.
According to Physicians for Human Rights, 34 of these deaths were related to government usage of tear gas originally manufactured by America-based Federal Laboratories. The lack of coverage by Arab media in the Persian Gulf, as compared to other Arab Spring uprisings, has sparked several controversies.
According to Amnesty International, "Ten years after Bahrain's popular uprising, systemic injustice has intensified and political repression targeting dissidents, human rights defenders, clerics and independent civil society have effectively shut any space for the peaceful exercise of the right to freedom of expression or peaceful activism". Bahrain remains militarily and financially dependent on Saudi Arabia and the UAE, though this is changing with the economic reforms being implemented by the government.
2026 Iran war
On 28 February 2026, the United States and Israel launched joint airstrikes on Iran, killing the supreme leader of Iran and many other Iranian officials, starting a war with the stated goal of regime change. Iran responded with missile and drone strikes against Israel and US bases and US allies in the region, including Bahrain, which suffered material and civilian casualties.
Geography
Bahrain is a generally flat and arid archipelago in the Persian Gulf. It consists of a low desert plain rising gently to a low central escarpment with the highest point the 134 m (440 ft) Mountain of Smoke (Jabal ad Dukhan). Bahrain had a total area of 665 km2 (257 sq mi) but due to land reclamation, the area increased to 780 km2 (300 sq mi).
