The Middle East is a region centred on western Asia and northern Africa whose exact extent depends substantially on whether one uses a geographic, cultural, religious, or political definition. The most common definition includes the Arab countries of Western Asia (Iraq, Syria, Lebanon, Jordan, Israel and the Palestinian territories, Saudi Arabia, Yemen, Oman, the UAE, Qatar, Bahrain, Kuwait), plus Iran and Turkey, plus Egypt. Broader definitions extend into the rest of North Africa (Libya, Tunisia, Algeria, Morocco) and sometimes Sudan, Mauritania, and even further. The term has Anglo-American origins from the early 20th century, replacing the older "Near East" used for similar territories. The term itself is contested in the region — "Middle East" is implicitly defined from a European perspective ("middle" of what east?) and various regional and academic alternatives have been proposed without displacing the dominant English-language usage. The Middle East, however defined, contains approximately 600 million people, is the centre of the global oil and gas economy, includes the holy sites of three major world religions, and has been one of the most politically and militarily contested regions on Earth for the past century.
The Naming
The term "Middle East" was first used systematically by the American naval theorist Alfred Thayer Mahan in 1902 to describe the strategic region around the Persian Gulf — the "middle east" between the "Near East" (the Ottoman territories and the eastern Mediterranean) and the "Far East" (the European-imperial term for East and Southeast Asia). The British strategist Valentine Chirol popularised the term shortly afterward, applying it more broadly. The British Middle East Command of the Second World War cemented the term in official usage. After the Second World War, the term progressively replaced "Near East" in most English-language usage. The implicit Eurocentric perspective is one of the criticisms levelled at the term; the Arabic equivalent al-Sharq al-Awsaṭ ("the Middle East") and similar terms in Persian, Hebrew, and Turkish are direct translations from English rather than indigenous regional concepts. Alternative terms — "West Asia," "Southwest Asia," "Western Asia and North Africa" (WANA), "Middle East and North Africa" (MENA) — have been variously proposed and adopted in different academic and institutional contexts but none has displaced "Middle East" in general English-language usage.
The Geographic Diversity
The Middle East is geographically more diverse than its arid reputation suggests. The region contains: substantial mountain systems (the Zagros Mountains of Iran, the Pontic and Taurus Mountains of Turkey, the Lebanon and Anti-Lebanon Mountains, the Yemen Highlands, the Atlas Mountains of North Africa); major river systems (the Tigris and Euphrates of Mesopotamia, the Nile of Egypt and Sudan, the Jordan of the Levant); enclosed seas (the Persian Gulf, the Red Sea, the Mediterranean coast, the Caspian Sea); the largest sand desert in the world (the Rub' al-Khali, the "Empty Quarter" of Saudi Arabia); substantial coastal plains; high plateaus (the Iranian plateau, the Anatolian plateau); and the lowest place on land (the Dead Sea at -430 metres elevation). The climate ranges from genuinely Mediterranean (in coastal Lebanon and northern Israel) to hyper-arid (in central Saudi Arabia and the Empty Quarter) to monsoon-influenced (in southern Yemen and Oman). The agricultural and hydrological geography of the region is substantially shaped by where rain falls and where it does not — and the region as a whole is one of the most water-stressed parts of the world.
The Religious Geography
The Middle East is the birthplace of three of the world's major religions — Judaism, Christianity, and Islam — and contains many of their holiest sites. Jerusalem is sacred to all three. Mecca and Medina in western Saudi Arabia are the two holiest cities of Islam. Bethlehem, Nazareth, and various other sites are central to Christianity. The religious composition of the modern Middle East is approximately 90 percent Muslim (predominantly Sunni, with significant Shia majorities in Iran, Iraq, Bahrain, and Azerbaijan, and significant Shia minorities in several other countries), plus minorities of Christians (substantial communities in Egypt, Lebanon, Syria, Iraq, Israel and the Palestinian territories, and elsewhere), Jews (concentrated in Israel, with a complex history of relocation from across the region), Druze (in Lebanon, Syria, Israel), Alawites (in Syria), Yazidis (in northern Iraq), and various smaller communities. The religious geography has been substantially reshaped by the political events of the past century, particularly the Arab-Israeli conflict, the various civil wars (Lebanon, Syria, Yemen, Iraq), and the ISIS campaigns of 2014-17 that produced substantial Yazidi and Christian population displacements.
The Oil and Gas
The Middle East is the most important region in the global hydrocarbon economy. The countries around the Persian Gulf — Saudi Arabia, Iran, Iraq, Kuwait, UAE, Qatar, Bahrain — collectively contain approximately half of the world's proven oil reserves and a substantial fraction of the natural gas reserves. The development of the Middle Eastern oil industry from the 1908 discovery of oil in Iran (which led to the founding of what became BP), through the 1938 Saudi discovery, the post-WW2 expansion, the 1973 OPEC oil embargo, the 1979 Iranian Revolution and subsequent oil price spike, the 1990 Iraqi invasion of Kuwait and Gulf War, the 2003 Iraq War, and the various subsequent shifts in oil markets, has substantially shaped global politics and economics for over a century. The dependence of major industrialised economies on Middle Eastern energy has produced substantial geopolitical entanglements; the energy transition currently underway in many of those economies will progressively reshape the relationship over coming decades, though the region's strategic importance will not vanish even as direct energy dependence reduces.
The Arab-Israeli Conflict
The Arab-Israeli conflict, beginning with the founding of the State of Israel in 1948 and continuing in various forms through the present, has been the most prominent single political theme of the modern Middle East. The 1948-49 war, the 1956 Suez Crisis, the 1967 Six-Day War (in which Israel captured the West Bank, Gaza, the Golan Heights, the Sinai, and East Jerusalem), the 1973 Yom Kippur War, the various Lebanon wars (notably 1982 and 2006), the multiple Gaza wars (2008-09, 2012, 2014, 2023-2024), and the ongoing situation in Israel and the Palestinian territories have produced enormous human costs and substantial regional and global political effects. The various peace agreements — the 1979 Egypt-Israel treaty, the 1994 Israel-Jordan treaty, the 2020 Abraham Accords with the UAE, Bahrain, Sudan, and Morocco — have produced partial normalisation between Israel and several Arab states but have not resolved the central Israeli-Palestinian question, which remains the most consequential unresolved political issue in the region.
The Iran-Saudi Rivalry
The other major structural conflict of the modern Middle East is the rivalry between Saudi Arabia (and the broader Sunni Arab Gulf states) and Iran. The conflict has religious dimensions (Sunni vs Shia, with the Saudi religious establishment and the Iranian clerical regime each presenting itself as a leading authority of its tradition), strategic dimensions (the competition for regional influence in Iraq, Syria, Lebanon, Yemen, and other proxy theatres), and economic dimensions (oil pricing and market share). The 1979 Iranian Revolution, the 1980-88 Iran-Iraq War, the 2003 toppling of Saddam Hussein and subsequent Iranian expansion into Iraq, the 2011-onward Syrian civil war, the 2014-onward Yemen war, the 2020 assassination of Iranian general Qasem Soleimani, and the various nuclear-program negotiations and disputes have all been shaped by the Iran-Saudi rivalry. The 2023 Chinese-mediated diplomatic normalisation between Riyadh and Tehran has produced partial de-escalation but the underlying structural rivalry continues.
The Arab Spring
The 2010-12 wave of popular uprisings across the Arab world — beginning in Tunisia in December 2010 and spreading to Egypt, Libya, Yemen, Syria, Bahrain, and protests of varying scale in nearly every other Arab country — was one of the major political events of the early 21st century. The outcomes varied dramatically: Tunisia produced a sustained democratic transition (though one that has substantially backslid since 2021); Egypt produced an initial transition followed by a 2013 military coup that has consolidated authoritarian rule under Sisi; Libya, Yemen, and Syria produced civil wars with substantial international involvement and continuing humanitarian crises; Bahrain produced a Gulf-state-supported crackdown that maintained the existing regime; the Gulf monarchies (Saudi Arabia, UAE, Qatar, Kuwait, Oman) generally weathered the protests without regime change. The Arab Spring's legacy has been substantially less democratic transformation than the early 2011 optimism suggested but substantial political and social change nonetheless.
The Demographic Future
The Middle East's demographic trajectory is one of the major underlying forces shaping its future. The region has been one of the most demographically dynamic in the world over the past 60 years; populations have multiplied several times over since 1960, with substantial implications for labour markets, urbanisation, water and food security, and political stability. The "youth bulge" — the high proportion of population in young age categories — has been one of the structural factors in the political volatility of the past two decades. Birth rates have been declining substantially across the region, with countries including Iran, Turkey, Tunisia, and most of the Gulf states now at or below replacement fertility. The next 30-40 years will see the demographic transition proceed across the region, with implications for labour markets, social services, and the political balance between different age groups that are still emerging.
The Strategic Future
The Middle East's strategic position will continue to be shaped by the interaction of energy economics, geopolitics, climate change, demographic transition, and the unresolved political conflicts. The energy transition will progressively reduce direct global dependence on Middle Eastern oil and gas but will not eliminate the strategic importance of the region's position at the centre of multiple major trade routes and the energy infrastructure that will continue to be relevant for decades. The Russian and Chinese expansion of engagement with the region has produced substantial reconfiguration of external power relationships. The Israeli-Palestinian, Iranian-Saudi, and various civil war situations remain unresolved. Climate change — particularly water stress and rising temperatures — will produce substantial new pressures on the region. The Middle East in 2026 is at a particularly complex strategic moment, with multiple major forces converging and the trajectory of the next several decades highly uncertain.
