The Arabian Peninsula (Arabic: شبه الجزيرة العربية, romanized: shibh al-jazīra al-ʿarabiyya, or جزيرة العرب, jazīrat al-ʿarab, 'the Island of Arabs'), or simply Arabia, is a peninsula in West Asia, situated north-east of Africa on the Arabian plate. At 3,237,500 km (1.25 million sq mi), comparable in size to India, the Arabian Peninsula is the largest peninsula in the world.

Geographically, the Arabian Peninsula comprises Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE) and Yemen, as well as southern Iraq and Jordan. The largest of these is Saudi Arabia. In ancient antiquity, particularly from the 9th century BC to the 7th century AD, the Sinai Peninsula was also considered a part of Arabia.

Pakistan, officially the Islamic Republic of Pakistan, is a country in South Asia. It is the fifth-most populous country, with a population of over 241.5 million, having the second-largest Muslim population as of 2023. Islamabad is the nation's capital, while Karachi is its largest city and financial centre. Pakistan is the 33rd-largest country by area. Bounded by the Arabian Sea on the south, the Gulf of Oman on the southwest, and the Sir Creek on the southeast, it shares land borders with India to the east; Afghanistan to the west; Iran to the southwest; and China to the northeast. It shares a maritime border with Oman in the Gulf of Oman, and is separated from Tajikistan in the northwest by Afghanistan's narrow Wakhan Corridor.

Pakistan is the site of several ancient cultures, including the 8,500-year-old Neolithic site of Mehrgarh in Balochistan, the Indus Valley Civilisation of the Bronze Age, and the ancient Gandhara civilisation. The regions that compose the modern state of Pakistan were the realm of multiple empires and dynasties, including the Achaemenid, the Maurya, the Kushan, the Gupta; the Umayyad Caliphate in its southern regions, the Hindu Shahis, the Ghaznavids, the Delhi Sultanate, the Samma, the Shah Miris, the Mughals, and finally, the British Raj from 1858 to 1947.

Eastern Arabia, also known as Greater Bahrain or Bahrain Region (Arabic: ٱلْبَحْرَيْن, romanized: Al-Baḥrayn), is a historical region encompassing the eastern part of the Arabian Peninsula stretching from Basra to Khasab along the coast of the Persian Gulf. It includes parts of the modern-day states of Bahrain, Iraq (Basra Governorate), Kuwait, Oman, Qatar, Saudi Arabia (Eastern Province), and the United Arab Emirates. The entire coastal strip of Eastern Arabia was known as "Bahrain" for a millennium.

Until very recently, the whole of Eastern Arabia, from the Shatt al-Arab to the mountains of Oman, was a place where people moved around, settled and married unconcerned by national borders. The people of Eastern Arabia shared a culture based on the sea, as seafaring peoples.

Saudi Arabia, officially the Kingdom of Saudi Arabia (KSA), is a country in West Asia. Located in the center of the Middle East, it covers the bulk of the Arabian Peninsula and has a land area of about 2,150,000 km (830,000 sq mi), making it the fifth-largest country in Asia, the largest in the Middle East, and the twelfth-largest in the world. It is bordered by the Red Sea to the west; Jordan, Iraq, and Kuwait to the north; the Persian Gulf, Bahrain, Qatar and the United Arab Emirates to the east; Oman to the southeast; and Yemen to the south. The Gulf of Aqaba in the northwest separates Saudi Arabia from Egypt and Israel. Saudi Arabia is the only country with a coastline along both the Red Sea and the Persian Gulf, and most of its terrain consists of arid desert, lowland, steppe, and mountains. The capital and largest city is Riyadh; other major cities include Jeddah and the two holiest cities in Islam, Mecca and Medina. With a population of almost 32.2 million, Saudi Arabia is the fourth most populous country in the Arab world.

Pre-Islamic Arabia, the territory that constitutes modern-day Saudi Arabia, was the site of several ancient cultures and civilizations; the prehistory of Saudi Arabia shows some of the earliest traces of human activity outside Africa. Islam emerged in what is now Saudi Arabia in the early seventh century. Islamic prophet Muhammad united the population of the Arabian Peninsula and created a single Islamic religious polity. Following his death in 632, his followers expanded Muslim rule beyond Arabia, conquering territories in North Africa, Central, South Asia and Iberia within decades. Arab dynasties originating from modern-day Saudi Arabia founded the Rashidun (632–661), Umayyad (661–750), Abbasid (750–1517), and Fatimid (909–1171) caliphates, as well as numerous other Muslim states in Asia, Africa, and Europe.

The United Arab Emirates (UAE), also known simply as the Emirates, is a country in West Asia, situated at the eastern end of the Arabian Peninsula. It is a federal semi-constitutional monarchy made up of seven emirates, with Abu Dhabi serving as its national capital. The UAE borders Oman to the east and northeast, and Saudi Arabia to the southwest; it shares maritime borders with Qatar and Iran in the Persian Gulf, and with Oman in the Gulf of Oman. As of 2024, the UAE has an estimated population of over 10 million; Dubai is the country's largest city. Islam is the majority religion and Arabic is the official language; English is the most spoken language and the language of business.

The present-day United Arab Emirates is located within the historical region of Eastern Arabia, which was oriented to maritime trade and seafaring. The Portuguese arrived in the region around 1500 and set up bases on the territory while waging wars against the Persians. After their expulsion, the Dutch controlled the straits and established global maritime dominance. By the 19th century, with pearling becoming a major economic activity, piracy became rampant in the gulf, prompting British intervention; local sheikhdoms formed a pact with the United Kingdom to create the Trucial States, a British protectorate that was effectively shielded from attempted Saudi and Omani suzerainty. The Trucial States remained under British influence until full independence as the United Arab Emirates in 1971. Zayed bin Sultan Al Nahyan, ruler of Abu Dhabi and the country's first president (1971–2004), oversaw rapid development of the Emirates by investing revenues from newly found oil into healthcare, education, and infrastructure.

Yemen, officially the Republic of Yemen, is a country in West Asia. Including the Socotra Archipelago, mainland Yemen is located in southern Arabia; bordering Saudi Arabia to the north, Oman to the northeast, the south-eastern part of the Arabian Sea to the east, the Gulf of Aden to the south, and the Red Sea to the west, sharing maritime borders with Djibouti, Eritrea, and Somalia across the Horn of Africa. Covering roughly 455,503 square kilometres (175,871 square miles), with a coastline of approximately 2,000 kilometres (1,200 miles), Yemen is the second largest country on the Arabian Peninsula. Sanaa is its constitutional capital and largest city. Yemen's estimated population is 34.7 million, mostly Arab Muslims. It is a member of the Arab League, the United Nations, the Non-Aligned Movement and the Organisation of Islamic Cooperation.

Owing to its geographic location, Yemen has been at the crossroads of many civilisations for over 7,000 years. The Sabaeans formed a thriving commercial kingdom that influenced parts of modern Ethiopia and Eritrea. In 275 CE, it was succeeded by the Himyarite Kingdom, which spanned much of Yemen's present-day territory and was heavily influenced by Judaism. Christianity arrived in the fourth century, followed by the rapid spread of Islam in the seventh century. From its conversion to Islam, Yemen became a center of Islamic learning, and Yemenite troops played a crucial role in early Islamic conquests. Much of Yemen's architecture survived until modern times. For centuries, it was a primary producer of coffee, exported through the port of Mocha. Various dynasties emerged between the 9th and 16th centuries. During the 19th century, the country was divided between the Ottoman and British empires. After World War I, the Kingdom of Yemen was established, which in 1962 became the Yemen Arab Republic (North Yemen) following a civil war. In 1967, the People's Democratic Republic of Yemen (South Yemen) gained its independence from the British Aden Protectorate, becoming the first and only communist state in the Middle East and the Arab world. In 1990, the two Yemeni states united to form the modern Republic of Yemen, with Ali Abdullah Saleh serving as the first president until his resignation in 2012 in the wake of the Arab Spring.

The Middle East and North Africa (MENA), also referred to as West Asia and North Africa (WANA) or South West Asia and North Africa (SWANA), is a geographic region which comprises the Middle East (also called West Asia) and North Africa together. It exists as an alternative to the concept of the Greater Middle East, which comprises the bulk of the Muslim world. The region has no standardized definition and groupings may vary, but the term typically includes countries like Algeria, Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Palestine, Qatar, Saudi Arabia, Syria, Tunisia, the United Arab Emirates, and Yemen.

As a regional identifier, the term "MENA" is often used in academia, military planning, disaster relief, media planning (as a broadcast region), and business writing. Moreover, it shares a number of cultural, economic, and environmental similarities across the countries that it spans; for example, some of the most extreme impacts of climate change will be felt in MENA.

Absolute monarchy is a form of monarchy in which the sovereign is the sole source of political power, unconstrained by constitutions, legislatures or other checks on their authority. Throughout history, there have been many absolute monarchs: some famous examples are Louis XIV of France and Frederick the Great of Prussia.

Absolute monarchies today include Brunei, Eswatini, Oman, Saudi Arabia, Vatican City, and the individual emirates composing the United Arab Emirates, which itself is a federation of such monarchies – a federal monarchy. Although absolute monarchies are sometimes supported by legal documents (such as the King's Law of Denmark–Norway), they are distinct from constitutional monarchies, in which the authority of the monarch is restricted (e.g. by legislature or unwritten customs) or balanced by that of other officials, such as a prime minister, as in the United Kingdom or the Nordic countries.

The Gulf of Oman or Sea of Oman (Arabic: خليج عمان khalīj ʿumān; Persian: دریای عمان daryâ-ye omân), also known as Gulf of Makran or Sea of Makran (Arabic: خلیج مکران khalīj makrān; Persian: دریای مکران daryâ-ye makrān), is a gulf in the Indian Ocean that connects the Arabian Sea with the Strait of Hormuz, which then runs to the Persian Gulf. It borders Iran and Pakistan on the north, Oman on the south, and the United Arab Emirates on the west.

The Akkadian Empire (/əˈkeɪdiən/) or kingdom of Akkad/Agade was an ancient kingdom, often thought to be the first known empire, succeeding the long-lived city-states of Sumer. Centered on the city of Akkad (/ˈækæd/ or /ˈɑːkɑːd/) and its surrounding region in modern-day Iraq, the empire united the Semitic Akkadian and Sumerian speakers under one rule and exercised significant influence across Mesopotamia, the Levant, modern-day Iran and Anatolia, sending military expeditions as far south as Dilmun and Magan (modern United Arab Emirates, Saudi Arabia, Bahrain, Kuwait, Qatar and Oman) in the Arabian Peninsula.

Established by Sargon of Akkad after defeating the Sumerian king Lugal-zage-si, it replaced the system of independent Sumero-Akkadian city-states and unified a vast region, stretching from the Mediterranean to Iran and from Anatolia to the Persian Gulf, under a centralized government. Sargon and his successors, especially his grandson Naram-Sin, expanded the empire through military conquest, administrative reforms, and cultural integration. Naram-Sin took the unprecedented step of declaring himself a living god and adopted the title "King of the Four Quarters." The Semitic Akkadian language became the empire’s lingua franca, although Sumerian (a language isolate) remained important in religion and literature. The empire was documented through inscriptions, administrative tablets, and seals, including notable sources like the Bassetki Statue. Enheduanna, Sargon’s daughter, served as high priestess and is recognized as the first known named author in history.

Arab culture is the culture of the Arabs, from the Atlantic Ocean in the west to the Arabian Sea in the east, in a region of the Middle East and North Africa known as the Arab world. The various religions the Arabs have adopted throughout their history and the various empires and kingdoms that have ruled and took lead of the civilization have contributed to the ethnogenesis and formation of modern Arab culture. Language, literature, gastronomy, art, architecture, music, spirituality, philosophy and mysticism are all part of the cultural heritage of the Arabs.

The countries of the Arab world, from Morocco to Iraq, share a common culture, traditions, language and history that give the region a distinct identity and distinguish it from other parts of the Muslim world. The Arab world is sometimes divided into separate regions depending on different cultures, dialects and traditions, such as the Arabian Peninsula (Kuwait, Bahrain, Qatar, Saudi Arabia, Oman, Yemen and the United Arab Emirates), Egypt, the Levant (Lebanon, Syria, Palestine and Jordan), the Maghreb (Libya, Tunisia, Algeria, Morocco and Mauritania), Mesopotamia (Iraq), and Sudan.

A qanāt (Persian: قَنَات) or kārīz (کَارِیز) is a water supply system that was developed in ancient Iran for the purpose of transporting usable water to the surface from an aquifer or a well through an underground aqueduct. Originating approximately 3,000 years ago, its function is essentially the same across the Middle East and North Africa, but it is known by a variety of regional names beyond today's Iran, including: kārēz in Afghanistan and Pakistan; foggāra in Algeria; khettāra in Algeria and Morocco; the daoudi-type falaj in Oman and the United Arab Emirates; and ʿuyūn in Saudi Arabia. In addition to those in Iran, the largest extant and functional qanats are located in Afghanistan, Xinjiang in China (the Turpan water system), Oman, and Pakistan.

Proving crucial to water supply in areas with hot and dry climates, a qanat enables water to be transported over long distances by largely eliminating the risk of much of it evaporating on the journey. The system also has the advantage of being fairly resistant to natural disasters, such as floods and earthquakes, as well as to man-made disasters, such as wartime destruction and water supply terrorism. Furthermore, it is almost insensitive to varying levels of precipitation, delivering a flow with only gradual variations from wet to dry years.

Overseas military bases of the United Kingdom enable the British Armed Forces to conduct expeditionary warfare and maintain a forward presence. Bases tend to be located in or near areas of strategic or diplomatic importance, often used for the build-up or resupply of military forces, as was seen during the 1982 Falklands War with the use of RAF Ascension Island as a staging post. Most of the bases are located on British Overseas Territories or former colonies which retain close diplomatic ties with the British government.

Apart from the main operating bases, the British military has personnel stationed at approximately 145 overseas military installations located across 42 countries. Most of these are small contingents. However, some sixty facilities are run directly by the British Armed Forces, including seventeen installations in Cyprus. Allied countries host British military personnel in some sixty-nine facilities, including in Oman, at sixteen locations, and Saudi Arabia, where there are fifteen. Six of the countries with a fixed UK military presence are featured on the Foreign and Commonwealth Office's list of 30 'Human Rights Priority Countries': Bahrain, Iraq, Saudi Arabia, Somalia, Syria and Yemen.

The Cooperation Council for the Arab States of the Gulf (Arabic: مجلس التعاون لدول الخليج العربيّة), also known as the Gulf Cooperation Council (GCC; Arabic: مجلس التعاون الخليجي), is a regional, intergovernmental, political, and economic union and military alliance comprising Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. The council's main headquarters is located in Riyadh, the capital of Saudi Arabia. The Charter of the GCC was signed on 25 May 1981, formally establishing the institution.

All current member states are monarchies, including three constitutional monarchies (Qatar, Kuwait, and Bahrain), two absolute monarchies (Saudi Arabia and Oman), and one federal monarchy (the United Arab Emirates, which is composed of seven member states, each of which is an absolute monarchy with its own emir). There have been discussions regarding the future membership of Jordan, Morocco, and Yemen. Iraq is the only Gulf Arab state that is not a GCC member.

The Mashriq (/məˈʃriːk/; Arabic: ْاَلْمَشْرِق, romanized: al-Mashriq, lit. 'the east'), also known as the Arab Mashriq (Arabic: اَلْمَشْرِقُ الْعَرَبِيُّ, romanized: al-Mashriq al-ʿArabi, lit. 'the Arab east'), sometimes spelled Mashreq or Mashrek, is the eastern part of the Arab world, as opposed to the Maghreb (western region), located in West Asia and eastern North Africa. It is the Arabic equivalent for the term Middle East. Poetically the "Place of Sunrise", the name is derived from the verb sharaqa (َشَرَق, "to shine, illuminate, radiate" and "to rise"), from the sh-r-q root (ش-ر-ق), referring to the east, where the sun rises.

The region includes the Arab-majority states of Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Oman, Palestine, Qatar, Saudi Arabia, Sudan, Syria, the United Arab Emirates, and Yemen.

The Strait of Hormuz (/hɔːrˈmuːz/ Persian: تنگهٔ هُرمُز Tangeh-ye Hormoz listen, Arabic: مَضيق هُرمُز Maḍīq Hurmuz) is a strait between the Persian Gulf and the Gulf of Oman. It provides the only sea passage from the Persian Gulf to the open ocean and is one of the world's most strategically important choke points. It has been so for centuries, with vast hinterlands rich in luxury trade good, but no easy access to lucrative trading ports. Babur's memoirs recount how almonds had to be carried from the distant Ferghana region in Central Asia to Hormuz to reach markets.

On the north coast lies Iran, and on the south coast lies the Musandam Peninsula, shared by the United Arab Emirates and the Musandam Governorate, an exclave of Oman. The strait is about 104 miles (90 nmi; 167 km) long, with a width varying from about 60 mi (52 nmi; 97 km) to 24 mi (21 nmi; 39 km).

Khasab (Arabic: خَصَب, romanized: Ḫaṣab) is a town and capital of the Musandam Governorate which is an exclave of Oman bordering the United Arab Emirates at the tip of the Musandam Peninsula by the Strait of Hormuz. It has been dubbed the "Norway of Arabia" because of its extensive fjord-like craggy inlets and desolate mountainscapes.

The town is surrounded by the northern mountains of the Western Hajar Range. Khasab has a fully functional hospital and several hotels, beaches and parks across the city. The city's population is dominated by ethnic Omanis from the mainland. Khasab also has a fort which is known as Khasab Fort. The sea port is dominated by the dhows which take tourists for a cruise across the natural, dry "fjords".

The Eastern Province (Arabic: المنطقة الشرقية‎, romanized: al-Mintaqah ash-Sharqīyah), also known as the Eastern Region, is a province in Saudi Arabia. It is the nation's largest province by area and the third most populous after Riyadh and Mecca provinces. As of 2022, the population is 5,125,254. Its name reflects its location in the eastern part of the country.

More than a third of the population is concentrated in the Dammam metropolitan area. With an estimated population of 1.53 million as of 2022, Dammam, the seat of the province, is the fourth most populous city in the kingdom. Other populous cities in the province include Qatif, Hofuf, Hafar al-Batin, Jubail and Khobar. The region is extremely popular among tourists for its beaches on the Persian Gulf (also known as the Arabian Gulf) and proximity to the other countries of the eastern Arab world, such as the United Arab Emirates, Qatar and Bahrain, with the latter being linked to the province via the 25 km (15 mi) long King Fahd Causeway. The Province also shares a border with Oman, Yemen, Kuwait and Iraq. The province is bordered to the west, from north to south, by the provinces of the Northern Borders, Hail, Al-Qassim, Riyadh and Najran.
