Bahrain

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.

=== 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.

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.

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.

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.

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.

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.

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.

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. In July 2026, Bahrain launched airstrikes on Iran for the first time in retaliation, along with Kuwait.

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).

Often described as an archipelago of 33 islands, extensive land reclamation projects have changed this; by August 2008 the number of islands and island groups had increased to 84. Bahrain does not share a land boundary with another country but does have a 161 km (100 mi) coastline. The country also claims a further 22 km (12 nmi) of territorial sea and a 44 km (24 nmi) contiguous zone. Bahrain's largest islands are Bahrain Island, the Hawar Islands, Muharraq Island, Umm an Nasan, and Sitra. Bahrain has mild winters and very hot, humid summers. The country's natural resources include large quantities of oil and natural gas as well as fish in the offshore waters. Arable land constitutes only 2.82% of the total area.

About 92% of Bahrain is desert with periodic droughts and dust storms, the main natural hazards for Bahrainis. In Bahrain forest cover is around 1% of the total land area, equivalent to 700 hectares (ha) of forest in 2020, up from 220 hectares (ha) in 1990. For the year 2015, 100% of the forest area was reported to be under public ownership.

Environmental issues facing Bahrain include desertification resulting from the degradation of limited arable land, coastal degradation (damage to coastlines, coral reefs, and sea vegetation) resulting from oil spills and other discharges from large tankers, oil refineries, distribution stations, and illegal land reclamation at places such as Tubli Bay. The agricultural and domestic sectors' over-utilisation of the Dammam Aquifer, the principal aquifer in Bahrain, has led to its salinisation by adjacent brackish and saline water bodies. A hydrochemical study identified the locations of the sources of aquifer salinisation and delineated their areas of influence. The investigation indicates that the aquifer water quality is significantly modified as groundwater flows from the northwestern parts of Bahrain, where the aquifer receives its water by lateral underflow from eastern Saudi Arabia to the southern and southeastern parts. Four types of salinisation of the aquifer are identified: brackish-water up-flow from the underlying brackish-water zones in north-central, western, and eastern regions; seawater intrusion in the eastern region; intrusion of sabkha water in the southwestern region; and irrigation return flow in a local area in the western region. Four alternatives for the management of groundwater quality that are available to the water authorities in Bahrain are discussed and their priority areas are proposed, based on the type and extent of each salinisation source, in addition to groundwater use in that area.

The Zagros Mountains across the Persian Gulf in Iran cause low-level winds to be directed toward Bahrain. Dust storms from Iraq and Saudi Arabia transported by northwesterly winds, locally called shamal wind, cause reduced visibility in the months of June and July.

Summers are very hot. The seas around Bahrain are very shallow, heating up quickly in the summer to produce very high humidity, especially at night. This is in stark contrast to other desert climates such as those of Baghdad or Phoenix. Summer temperatures may reach up to 40 °C (104 °F) under the right conditions. Rainfall in Bahrain is minimal and irregular. Precipitation mostly occurs in winter, with an average of 70.8 millimetres or 2.8 inches of rainfall recorded annually. The country experienced widespread flooding in April 2024 after heavy rainfall affected the Gulf region.

Due to climate change Bahrain is experiencing more frequent extreme heat, drought, flooding and dust storms and the threat of sea level rise. These conditions threaten Bahrain's food and water security, and are expected to become more severe in the future. Despite being a relatively low-emitting country overall, Bahrain was the second highest greenhouse gas emitter per capita in 2023, at approximately 42 tonnes per person. Most of Bahrain's emissions arise from burning fossil fuels in the energy sector. The nation has committed to net zero by 2060 and also aims to reduce its greenhouse gas emissions by 30% by 2035.

More than 330 species of birds were recorded in the Bahrain archipelago, 26 species of which breed in the country. Millions of migratory birds pass through the Persian Gulf region in the winter and autumn months. One globally endangered species, Chlamydotis undulata, is a regular migrant in the autumn. The many islands and shallow seas of Bahrain are globally important for the breeding of the Socotra cormorant; up to 100,000 pairs of these birds were recorded over the Hawar Islands. Bahrain's national bird is the bulbul while its national animal is the Arabian oryx. And the national flower of Bahrain is the beloved Deena.

Only 18 species of mammals are found in Bahrain, animals such as gazelles, desert rabbits and hedgehogs are common in the wild but the Arabian oryx was hunted to extinction on the island. Twenty-five species of amphibians and reptiles were recorded as well as 21 species of butterflies and 307 species of flora. The marine biotopes are diverse and include extensive sea grass beds and mudflats, patchy coral reefs as well as offshore islands. Sea grass beds are important foraging grounds for some threatened species such as dugongs and the green turtle. In 2003, Bahrain banned the capture of sea cows, marine turtles and dolphins within its territorial waters.

The Hawar Islands Protected Area provides valuable feeding and breeding grounds for a variety of migratory seabirds; it is an internationally recognised site for bird migration. The breeding colony of Socotra cormorant on Hawar Islands is the largest in the world, and the dugongs foraging around the archipelago form the second-largest dugong aggregation after Australia.

Bahrain has five designated protected areas, four of which are marine environments. They are:

Hawar Islands

Mashtan Island, off the coast of Bahrain.

Arad bay, in Muharraq.

Tubli Bay

Al Areen Wildlife Park, which is a zoo and a breeding centre for endangered animals, is the only protected area on land and also the only protected area which is managed on a day-to-day basis.

Bahrain is a semi-constitutional monarchy headed by King Shaikh Hamad bin Isa Al Khalifa. King Hamad enjoys wide executive powers which include appointing the prime minister and his ministers, commanding the Bahrain Defence Force, chairing the Higher Judicial Council, appointing the parliament's upper house and dissolving its elected lower house. The head of government is the prime minister. In 2010, about half of the cabinet was composed of the Al Khalifa family.

Bahrain has a bicameral National Assembly (al-Majlis al-Watani) consisting of the Shura Council (Majlis Al-Shura) with 40 seats and the Council of Representatives (Majlis Al-Nuwab) with 40 seats. The forty members of the Shura are appointed by the king. In the Council of Representatives, 40 members are elected by absolute majority vote in gerrymandered single-member constituencies to serve four-year terms. The appointed council "exercises a de facto veto" over the "rubber-stamp" elected, because draft acts must be approved so they may pass into law. After approval, the king may ratify and issue the act or return it within six months to the National Assembly where it may only pass into law if approved by two-thirds of both councils.

In 1973, the country held its first parliamentary elections; however, two years later, the late emir dissolved the parliament and suspended the constitution after parliament rejected the State Security Law. The period between 2002 and 2010 saw three parliamentary elections. The first, held in 2002 was boycotted by the opposition, Al Wefaq, which won a majority in the second in 2006 and third in 2010. A 2011 by-election was held to replace 18 members of Al Wefaq who resigned in protest against government crackdown.

According to the V-Dem Democracy indices Bahrain is 2023 the 4th least electoral democratic country in the Middle East. Similarly, according to International IDEA's Global State of Democracy (GSoD) Indices and Democracy Tracker, Bahrain performs in the low range on overall democratic measures, with particular weaknesses in social group equality, judicial independence, and freedom of association and assembly.

The opening up of politics saw big gains for both Shīa and Sunnī fundamentalists in elections, which gave them a parliamentary platform to pursue their policies. It gave a new prominence to clerics within the political system, with the most senior Shia religious leader, Sheikh Isa Qassim, playing a vital role. This was especially evident when in 2005 the government called off the Shia branch of the "Family law" after over 100,000 Shia took to the streets. Muslim fundamentalists opposed the law because "neither elected MPs nor the government has the authority to change the law because these institutions could misinterpret the word of God". The law was supported by women activists who said they were "suffering in silence". They managed to organise a rally attended by 500 participants. Ghada Jamsheer, a leading woman activist said the government was using the law as a "bargaining tool with opposition Islamic groups".

Analysts of democratisation in the Middle East cite the fundamentalist' references to respect human rights in their justification for these programmes as evidence that these groups can serve as a progressive force in the region. Some fundamentalist parties have been particularly critical of the government's readiness to sign international treaties such as the United Nations' International Convention on Civil and Political Rights. At a parliamentary session in June 2006 to discuss ratification of the convention, Sheikh Adel Mouwda, the former leader of a salafist party, Asalah, explained the party's objections: "The convention has been tailored by our enemies, God kill them all, to serve their needs and protect their interests rather than ours. This why we have eyes from the American Embassy watching us during our sessions, to ensure things are swinging their way".

The kingdom has a small but professional and well-equipped military called the Bahrain Defence Force (BDF), numbering around 8,200 personnel, including 6,000 in the Royal Bahraini Army, 700 in the Royal Bahraini Naval Force, and 1,500 in the Royal Bahraini Air Force. The BDF command structure includes the Bahrain Royal Guard, which is the size of one battalion and has its own armored vehicles and artillery. The Bahrain National Guard is separate from the BDF, though it is tasked with assisting it in defense from external threats, and it has about 2,000 personnel.

The supreme commander of the Bahraini military is King Hamad bin Isa Al Khalifa. The deputy supreme commander is the Crown Prince, Salman bin Hamad bin Isa Al Khalifa. The Commander-in-Chief of the BDF has been Field Marshal Khalifa bin Ahmed Al Khalifa since 2008.

The BDF is primarily equipped with American made equipment, such as the F-16 Fighting Falcon, F-5 Freedom Fighter, UH-60 Blackhawk, M60A3 tanks, and the ex-USS Jack Williams, an Oliver Hazard Perry class frigate renamed the RBNS Sabha. In August 2020, the UK's HMS Clyde was transferred to the Royal Bahrain Naval Force, with the ship renamed as RBNS Al-Zubara. In January 2024 the Bahraini Navy received a second Oliver Hazard Perry-class frigate, the former USS Robert G. Bradley, which was renamed RBNS Khalid bin Ali.

Bahrain was the first country in the Gulf to operate the F-16. In 2024 the Royal Bahraini Air Force expects to receive 16 aircraft of the modernised F-16 Block 70 variant, in addition to its current 20 F-16C/D and 12 F-5E/F fighters. The Royal Bahraini Army has 180 M60A3 main battle tanks, with 100 in active service and 80 in storage.

The Government of Bahrain has close relations with America, having signed a cooperative agreement with the American military, and has provided America a base in Juffair since the early 1990s. An American naval presence has existed since 1948. This is the home of the headquarters for Commander, American Naval Forces Central Command (COMUSNAVCENT) / American Fifth Fleet (COMFIFTHFLT), and around 6,000 American military personnel.

Bahrain participates in the Saudi Arabian-led intervention in Yemen against the Houthis and forces loyal to former President Ali Abdullah Saleh, who was deposed in the 2011 Arab Spring uprising.

The permanent British Royal Navy base at Mina Salman, HMS Jufair, was officially opened in April 2018.

Bahrain has established bilateral relations with 190 countries worldwide. As of 2012, Bahrain maintains a network of 25 embassies, three consulates and four permanent missions to the Arab League, United Nations and European Union respectively. Bahrain also hosts 36 embassies. America designated Bahrain a major non-NATO ally in 2001. Bahrain plays a modest, moderating role in regional politics and adheres to the views of the Arab League on Middle East peace and Palestinian rights by supporting the two state solution. Bahrain is also one of the founding members of the Gulf Cooperation Council. Relations with Iran tend to be tense as a result of a failed coup in 1981 which Bahrain blames Iran for and occasional claims of Iranian sovereignty over Bahrain by ultra-conservative elements in the Iranian public. In 2016, following the storming of the Saudi embassy in Tehran, both Saudi Arabia and Bahrain cut diplomatic relations with Iran. Bahrain and Israel established bilateral relations in 2020 under the Bahrain–Israel normalisation agreement.

Bahrain is the 81st most peaceful country in the world, according to the 2024 Global Peace Index.

The period between 1975 and 1999, known as the "State Security Law Era", saw wide range of human rights violations including arbitrary arrests, detention without trial, torture and forced exile. After Emir (now King) Hamad Al Khalifa succeeded his father Isa Al Khalifa in 1999, he introduced wide reforms and human rights improved significantly. These moves were described by Amnesty International as representing a "historic period of human rights".

Consensual male and female homosexual relations between adults over the age of 21 are legal in Bahrain, which is the only Muslim Gulf country where it has been legal since 1976.

Human rights conditions started to decline by 2007 when torture began to be employed again. In 2011, Human Rights Watch described the country's human rights situation as "dismal". Due to this, Bahrain lost some of the high International rankings it had gained before.

In 2011, Bahrain was criticised for its crackdown on the Arab spring uprising. In September, a government-appointed commission confirmed reports of grave human rights violations, including systematic torture. The government promised to introduce reforms and avoid repeating the "painful events". However, reports by human rights organisations Amnesty International and Human Rights Watch issued in April 2012 said the same violations were still happening.

Amnesty International's 2015 report on the country points to the continued suppression of dissent, restricted freedom of expression, unjust imprisonment, and frequent torture and other ill-treatment of its citizens. As of October 2014, Bahrain is ruled by an "authoritarian regime" and is rated as "Not Free" by America-based non-governmental Freedom House. Freedom House continues to label Bahrain as "not free" in its 2021 report. On 7 July 2016, the European Parliament adopted, with a large majority, a resolution condemning human rights abuses performed by Bahraini authorities, and strongly called for an end to the ongoing repression against the country's human rights defenders, political opposition and civil society.

In August 2017, American Secretary of State Rex Tillerson spoke against the discrimination of Shias in Bahrain, saying, "Members of the Shia community there continue to report ongoing discrimination in government employment, education, and the justice system," and that "Bahrain must stop discriminating against the Shia communities." He also stated that "In Bahrain, the government continue to question, detain and arrest Shia clerics, community members and opposition politicians." However, in September 2017, the American State Department has approved arms sales packages worth more than $3.8 billion to Bahrain including F-16 jets, upgrades, missiles and patrol boats. In its latest report Amnesty International accused both the American and British governments of turning a blind eye to horrific abuses of human rights by the ruling Bahraini regime. On 31 January 2018, Amnesty International reported that the Bahraini government expelled four of its citizens after having revoked their nationality in 2012, turning them into stateless people. On 21 February 2018, human rights activist Nabeel Rajab was sentenced to a further five years in jail for tweets and documentation of human rights violations. On behalf of the ruling family, Bahraini police have received training on how to deal with public protests from the British government.

On 11 July 2020, a government watchdog in Bahrain claimed that the confessions of two pro-democracy campaigners were extracted by torture. Mohammed Ramadhan and Husain Moosa from Bahrain were leading figures in the pro-democracy protests of 2011. They were arrested in 2014 and accused of killing a police officer. On 13 July 2020, the highest Court in Bahrain overruled the previous judgment and upheld the death sentences for both men. The judgment was criticised by Sayed Ahmed Alwadaei, the director of advocacy at the Bahrain Institute for Rights and Democracy (BIRD), who stated: "Today's verdict is yet another dark stain in the struggle for human rights in Bahrain."

The 761-page World Report 2021 published by the Human Rights Watch in January 2021 revealed that the situation of human rights did not improve in Bahrain in 2020. It highlighted that the repression against social media activities escalated, death sentences were upheld by the courts against opposition activists after unfair trials, and the critics continued to be prosecuted for peaceful expression. The country also increased the use of the death penalty, while it denied medical treatment to some of the prominent opposition figures being kept in detention. The Human Rights Watch said that Bahrain uses several repressive tools to silence and punish every person who dares to criticise the government.

In March 2021, Human Rights Watch (HRW) and the London-based Bahrain Institute for Rights and Democracy claimed that 13 children aged between 11 and 17 were beaten and threatened with rape and electric shocks after being detained in protest-related cases.
