Iran, officially the Islamic Republic of Iran (IRI) and also known as Persia, is a country in West Asia. It borders Iraq to the west, Turkey, Azerbaijan, and Armenia to the northwest, the Caspian Sea to the north, Turkmenistan to the northeast, Afghanistan to the east, Pakistan to the southeast, and the Gulf of Oman and the Persian Gulf to the south. Iran ranks 17th globally in both geographic size and population and is the sixth-largest country in Asia. Iran is officially an Islamic republic, divided into five regions with 31 provinces. Tehran is the nation's capital, largest city and financial center.

A cradle of civilization, Iran was inhabited by various peoples, including the Elamites from 3200 BCE in the southwest, before the arrival of the Iranian peoples. A large part of Iran was first unified as a political entity by the Medes under Cyaxares in the 7th century BCE and reached its territorial height in the 6th century BCE, when Cyrus the Great founded the Achaemenid Empire. Alexander the Great conquered the empire in the 4th century BCE. An Iranian rebellion in the 3rd century BCE established the Parthian Empire, which later liberated the country. In the 3rd century CE, the Parthians were succeeded by the Sasanian Empire, whose era was considered a golden age in the history of Iranian civilization. Ancient Iran saw some of the earliest developments of writing, agriculture, urbanization, religion and administration. Once a center for Zoroastrianism, Muslims conquered the region in the 7th century, leading to the Islamization of Iran. The literature, philosophy, mathematics, medicine, astronomy and art which blossomed during the Sasanian era were renewed during the Islamic Golden Age and Iranian Intermezzo, when a series of Iranian Muslim dynasties ended Arab rule, revived the Persian language, and ruled the country. This era was followed by Seljuk and Khwarazmian rule, Mongol conquests and the Timurid Renaissance from the 11th to 14th centuries.

In the 16th century, the native Safavid dynasty re-established a unified Iranian state with Twelver Shia Islam as the official religion. During the Afsharid Empire in the 18th century, Iran was a leading world power, but it lost this status after the Qajars took power in the 1790s. The early 20th century saw the Persian Constitutional Revolution and the establishment of the Pahlavi dynasty by Reza Shah, who ousted the last Qajar Shah in 1925. Attempts by Mohammad Mosaddegh to nationalize the oil industry led to the Anglo-American coup in 1953. The Iranian Revolution in 1979 overthrew the monarchy, and the Islamic Republic of Iran was established by Ruhollah Khomeini, the country's first supreme leader. In 1980, Iraq invaded Iran, sparking the eight-year-long Iran–Iraq War which ended in a stalemate. Iran is a threshold state with one of the most scrutinized nuclear programs it claims is solely for civilian purposes. This claim has been disputed by Israel and the Western world. In 2025, Israeli strikes on Iran escalated tensions into the Iran–Israel war. (Full article...)

Israel, officially the State of Israel, is a country in West Asia. It shares borders with Lebanon to the north, Syria to the north-east, Jordan to the east, Egypt to the south-west and the Mediterranean Sea to the west. It occupies the Palestinian territories of the West Bank in the east and the Gaza Strip in the south-west, as well as the Syrian Golan Heights in the north-east. Israel also has a small coastline on the Red Sea at its southernmost point, and part of the Dead Sea lies along its eastern border. Its proclaimed capital is Jerusalem, while Tel Aviv is its largest urban area and economic centre.

Israel is located in a region known as the Land of Israel, synonymous with the Palestine region, the Holy Land, and Canaan. In antiquity it was home to the Canaanite civilisation, followed by the kingdoms of Israel and Judah. Situated at a continental crossroad, the region experienced demographic changes under the rule of empires from the Romans to the Ottomans. European antisemitism in the late 19th century galvanised Zionism, which sought to establish a homeland for the Jewish people in Palestine and gained British support with the Balfour Declaration. After World War I, Britain occupied the region and established Mandatory Palestine in 1920. Increased Jewish immigration in the lead-up to the Holocaust and British foreign policy in the Middle East led to intercommunal conflict between Jews and Arabs, which escalated into a civil war in 1947 after the United Nations (UN) proposed partitioning the land between them.

After the end of the British Mandate for Palestine, Israel declared independence on 14 May 1948. Neighbouring Arab states invaded the area the next day, beginning the First Arab–Israeli War. An armistice in 1949 left Israel in control of more territory than the UN partition plan had called for; and no new independent Arab state was created as the rest of the former Mandate territory was held by Egypt and Jordan, respectively the Gaza Strip and the West Bank. The majority of Palestinian Arabs were either expelled or fled in what is known as the Nakba, with those remaining becoming the new state's main minority. Over the following decades, Israel's population increased greatly as the country received an influx of Jews who emigrated, fled or were expelled from the Arab world. (Full article...)

The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 states and a federal capital district, Washington, D.C. The 48 contiguous states border Canada to the north and Mexico to the south, with the semi-exclave of Alaska in the northwest and the archipelago of Hawaii in the Pacific Ocean. The United States also asserts sovereignty over five major island territories and various uninhabited islands in Oceania and the Caribbean. It is a megadiverse country, with the world's third-largest land area and third-largest population, exceeding 340 million.

Paleo-Indians migrated from North Asia to North America over 12,000 years ago, and formed various civilizations. Spanish colonization established Spanish Florida in 1513, the first European colony in what is now the continental United States. British colonization followed with the 1607 settlement of Virginia, the first of the Thirteen Colonies. Forced migration of enslaved Africans supplied the labor force to sustain the Southern Colonies' plantation economy. Clashes with the British Crown over taxation and lack of parliamentary representation sparked the American Revolution, leading to the Declaration of Independence on July 4, 1776. Victory in the 1775–1783 Revolutionary War brought international recognition of U.S. sovereignty and fueled westward expansion, dispossessing native inhabitants. As more states were admitted, a North–South division over slavery led the Confederate States of America to attempt secession and fight the Union in the 1861–1865 American Civil War. With the United States' victory, slavery was abolished nationally. By 1900, the country had established itself as a great power, a status solidified after its involvement in World War I. Following Japan's attack on Pearl Harbor in 1941, the U.S. entered World War II. Its aftermath left the U.S. and the Soviet Union as rival superpowers, competing for ideological dominance and international influence during the Cold War. The Soviet Union's collapse in 1991 ended the Cold War, leaving the U.S. as the world's sole superpower.

The U.S. national government is a presidential constitutional federal republic and representative democracy with three separate branches: legislative, executive, and judicial. It has a bicameral national legislature composed of the House of Representatives (a lower house based on population) and the Senate (an upper house based on equal representation for each state). Federalism grants substantial autonomy to the 50 states. In addition, 574 Native American tribes have sovereignty rights, and there are 326 Native American reservations. Since the 1850s, the Democratic and Republican parties have dominated American politics, while American values are based on a democratic tradition inspired by the Enlightenment movement.

Palestine, officially the State of Palestine, is a country in West Asia. Recognized by 147 of the UN's 193 member states, it encompasses the Israeli-occupied West Bank, including East Jerusalem, and the Gaza Strip, collectively known as the occupied Palestinian territories. The territories share the vast majority of their borders with Israel, with the West Bank bordering Jordan to the east and the Gaza Strip bordering Egypt to the southwest. It has a total land area of 6,020 square kilometres (2,320 sq mi) while its population exceeds five million. Its proclaimed capital is Jerusalem, while Ramallah serves as its de facto administrative center. Gaza City was its largest city prior to evacuations in 2023.

Situated at a continental crossroad, the Palestine region was ruled by various empires and experienced various demographic changes from antiquity to the modern era. It was treading ground for the Nile and Mesopotamian armies and merchants from North Africa, China and India. The region has religious significance. The ongoing Israeli–Palestinian conflict dates back to the rise of the Zionist movement, supported by the United Kingdom during World War I. The war saw Britain occupying Palestine from the Ottoman Empire, where it set up Mandatory Palestine under the auspices of the League of Nations. Increased Jewish immigration led to intercommunal conflict between Jews and Palestinian Arabs, which escalated into a civil war in 1947 after a proposed partitioning by the United Nations was rejected by the Palestinians.

The 1948 Palestine war saw the forcible displacement of a majority of the Arab population, and consequently the establishment of Israel; these events are referred to by Palestinians as the Nakba ('catastrophe'). In the Six-Day War in 1967, Israel occupied the West Bank and the Gaza Strip, which had been held by Jordan and Egypt respectively. The Palestine Liberation Organization (PLO) declared independence in 1988. In 1993, the PLO signed the Oslo Accords with Israel, creating limited PLO governance in the West Bank and Gaza Strip through the Palestinian Authority (PA). Israel withdrew from Gaza in its unilateral disengagement in 2005, but the territory is still considered to be under military occupation and has been blockaded by Israel. In 2007, internal divisions between political factions led to a takeover of Gaza by Hamas. Since then, the West Bank has been governed in part by the Fatah-led PA, while the Gaza Strip has remained under the control of Hamas. (Full article...)

Nine sovereign states are generally understood to possess nuclear weapons, though only eight formally acknowledge possessing them. In order of acquisition of nuclear weapons, these are the United States, Russia (as successor to the former Soviet Union), the United Kingdom, France, China, Israel (not formally acknowledged), India, Pakistan, and North Korea.

The first five of these are the nuclear-weapon states (NWS) as defined by the Nuclear Non-Proliferation Treaty (NPT). They are also the permanent members of the United Nations Security Council and the only nations confirmed to possess thermonuclear weapons. Israel, India, and Pakistan never joined the NPT, while North Korea acceded in 1983 but announced its withdrawal in 2003.

Israel is widely understood to have nuclear weapons, with a medium-sized arsenal, but does not officially acknowledge it, maintaining a policy of deliberate ambiguity. One possible motivation for nuclear ambiguity is deterrence with minimum political friction. (Full article...)

India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area; the most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago. Their long occupation, predominantly in isolation as hunter-gatherers, has made the region highly diverse. Settled life emerged on the subcontinent in the western margins of the Indus river basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. By 1200 BCE, an archaic form of Sanskrit, an Indo-European language, had diffused into India from the northwest. Its hymns recorded the early dawnings of Hinduism in India. India's pre-existing Dravidian languages were supplanted in the northern regions. By 400 BCE, caste had emerged within Hinduism, and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity. Early political consolidations gave rise to the loose-knit Maurya and Gupta Empires. Widespread creativity suffused this era, but the status of women declined, and untouchability became an organized belief. In South India, the Middle kingdoms exported Dravidian language scripts and religious cultures to the kingdoms of Southeast Asia.

In the early medieval era, Christianity, Islam, Judaism, and Zoroastrianism became established on India's southern and western coasts. Muslim armies from Central Asia intermittently overran India's northern plains in the second millennium. The resulting Delhi Sultanate drew northern India into the cosmopolitan networks of medieval Islam. In south India, the Vijayanagara Empire created a long-lasting composite Hindu culture. In the Punjab, Sikhism emerged, rejecting institutionalised religion. The Mughal Empire ushered in two centuries of economic expansion and relative peace, leaving a rich architectural legacy. Gradually expanding rule of the British East India Company turned India into a colonial economy but consolidated its sovereignty. British Crown rule began in 1858. The rights promised to Indians were granted slowly, but technological changes were introduced, and modern ideas of education and the public life took root. A nationalist movement emerged in India, the first in the non-European British empire and an influence on other nationalist movements. Noted for nonviolent resistance after 1920, it became the primary factor in ending British rule. In 1947, the British Indian Empire was partitioned into two independent dominions, a Hindu-majority dominion of India and a Muslim-majority dominion of Pakistan. A large-scale loss of life and an unprecedented migration accompanied the partition. (Full article...)

Gross domestic product (GDP) is the market value of all final goods and services from a nation in a given year. Countries are sorted by nominal GDP estimates from financial and statistical institutions, which are calculated at market or government official exchange rates. Nominal GDP does not take into account differences in the cost of living in different countries, and the results can vary greatly from one year to another based on fluctuations in the exchange rates of the country's currency. Such fluctuations may change a country's ranking from one year to the next, even though they often make little or no difference in the standard of living of its population.

Comparisons of national wealth are also frequently made based on purchasing power parity (PPP), to adjust for differences in the cost of living in different countries. Other metrics, nominal GDP per capita and a corresponding GDP (PPP) per capita, are used for comparing national standard of living. On the whole, PPP per capita figures are less spread than nominal GDP per capita figures.

The rankings of national economies over time have changed considerably; the economy of the United States surpassed the British Empire's output around 1916, which in turn had surpassed the economy of the Qing dynasty in aggregate output decades earlier. Since China's transition to a socialist market economy through controlled privatisation and deregulation, the country has seen its ranking increase from ninth in 1978, to second in 2010; China's economic growth accelerated during this period and its share of global nominal GDP surged from 2% in 1980 to 18% in 2021.

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in north-western Europe, off the coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The UK includes the island of Great Britain, the north-eastern part of the island of Ireland, and most of the smaller islands within the British Isles, covering 94,354 square miles (244,376 km²). Northern Ireland shares a land border with the Republic of Ireland; otherwise, the UK is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. It maintains sovereignty over the British Overseas Territories, which are located across various oceans and seas globally. The UK had an estimated population of over 68.2 million people in 2023. The capital and largest city of both England and the UK is London. The cities of Edinburgh, Cardiff and Belfast are the national capitals of Scotland, Wales and Northern Ireland respectively.

The UK has been inhabited continuously since the Neolithic. In AD 43 the Roman conquest of Britain began; the Roman departure was followed by Anglo-Saxon settlement. In 1066 the Normans conquered England. With the end of the Wars of the Roses the Kingdom of England stabilised and began to grow in power, resulting by the 16th century in the annexation of Wales and the establishment of the British Empire. Over the course of the 17th century the role of the British monarchy was reduced, particularly as a result of the English Civil War. In 1707 the Kingdom of England and the Kingdom of Scotland united under the Treaty of Union to create the Kingdom of Great Britain. In the Georgian era the office of prime minister became established. The Acts of Union 1800 incorporated the Kingdom of Ireland to create the United Kingdom of Great Britain and Ireland in 1801. Most of Ireland seceded from the UK in 1922 as the Irish Free State, and the Royal and Parliamentary Titles Act 1927 created the present United Kingdom.

The UK became the first industrialised country and was the world's foremost power for the majority of the 19th and early 20th centuries, particularly during the Pax Britannica between 1815 and 1914. The British Empire was the leading economic power for most of the 19th century, a position supported by its agricultural prosperity, its role as a dominant trading nation, a massive industrial capacity, significant technological achievements, and the rise of 19th-century London as the world's principal financial centre. At its height in the 1920s the empire encompassed almost a quarter of the world's landmass and population, and was the largest empire in history. However, its involvement in the First World War and the Second World War damaged Britain's economic power, and a global wave of decolonisation led to the independence of most British colonies.

Cyprus (/ˈsaɪprəs/ ^ⓘ), officially the Republic of Cyprus, is an island country in the eastern Mediterranean Sea. Situated in West Asia, its cultural identity and geopolitical orientation are overwhelmingly Southeast European. Cyprus is the third largest and third most populous island in the Mediterranean, after Sicily and Sardinia. It is located southeast of Greece, south of Turkey, west of Syria and Lebanon, northwest of Israel and Palestine, and north of Egypt. Its capital and largest city is Nicosia. Cyprus hosts the British military bases Akrotiri and Dhekelia, whilst the northeast portion of the island is de facto governed by the self-declared Turkish Republic of Northern Cyprus, which is separated from the Republic of Cyprus by the United Nations Buffer Zone.

Cyprus was first settled by hunter-gatherers around 13,000 years ago, with farming communities emerging by 8500 BC. The late Bronze Age saw the emergence of Alashiya, an urbanised society closely connected to the wider Mediterranean world. Cyprus experienced waves of settlement by Mycenaean Greeks at the end of the 2nd millennium BC. Owing to its rich natural resources (particularly copper) and strategic position at the crossroads of Europe, Africa, and Asia, the island was subsequently contested and occupied by several empires, including the Assyrians, Egyptians, and Persians, from whom it was seized in 333 BC by Alexander the Great. Successive rule by Ptolemaic Egypt, the Classical and Eastern Roman Empire, Arab caliphates, the French Lusignans, and the Venetians was followed by over three centuries of Ottoman dominion (1571–1878). Cyprus was placed under British administration in 1878 pursuant to the Cyprus Convention and formally annexed by the United Kingdom in 1914.

The island's future became a matter of disagreement between its Greek and Turkish communities. Greek Cypriots sought enosis, or union with Greece, which became a Greek national policy in the 1950s. Turkish Cypriots initially advocated for continued British rule, then demanded the annexation of the island to Turkey, with which they established the policy of taksim: portioning Cyprus and creating a Turkish polity in the north of the island. Following nationalist violence in the 1950s, Cyprus was granted independence in 1960. The crisis of 1963–64 brought further intercommunal violence between the two communities, displaced more than 25,000 Turkish Cypriots into enclaves, and ended Turkish Cypriot political representation. On 15 July 1974, a coup d'état was staged by Greek Cypriot nationalists and elements of the Greek military junta. This action precipitated the Turkish invasion of Cyprus on 20 July, which captured the present-day territory of Northern Cyprus and displaced over 150,000 Greek Cypriots and 50,000 Turkish Cypriots. A separate Turkish Cypriot state in the north was established by unilateral declaration in 1983, which was widely condemned by the international community and remains recognised only by Turkey. These events and the resulting political situation remain subject to an ongoing dispute. (Full article...)

China, officially the People's Republic of China (PRC), is a country in East Asia. With a population exceeding 1.4 billion, it is the second-most populous country after India, representing 17.4% of the world population. China spans the equivalent of five time zones and borders fourteen countries by land across an area of nearly 9.6 million square kilometers (3,700,000 sq mi), making it the third-largest country by land area. The country is divided into 33 province-level divisions: 22 provinces, 5 autonomous regions, 4 municipalities, and 2 semi-autonomous special administrative regions. Beijing is the country's capital, while Shanghai is its most populous city by urban area and largest financial center.

Considered one of six cradles of civilization, China saw the first human inhabitants in the region arriving during the Paleolithic. By the late 2nd millennium BCE, the earliest dynastic states had emerged in the Yellow River basin. The 8th–3rd centuries BCE saw a breakdown in the authority of the Zhou dynasty, accompanied by the emergence of administrative and military techniques, literature, philosophy, and historiography. In 221 BCE, China was unified under an emperor, ushering in more than two millennia of imperial dynasties including the Qin, Han, Tang, Yuan, Ming, and Qing. With the invention of gunpowder and paper, the establishment of the Silk Road, and the building of the Great Wall, Chinese culture flourished and has heavily influenced both its neighbors and lands further afield. However, China began to cede parts of the country in the late 19th century to various European powers by a series of unequal treaties. After decades of Qing China on the decline, the 1911 Revolution overthrew the Qing dynasty and the monarchy and the Republic of China (ROC) was established the following year.

The country under the nascent Beiyang government was unstable and ultimately fragmented during the Warlord Era, which was ended upon the Northern Expedition conducted by the Kuomintang (KMT) to reunify the country. The Chinese Civil War began in 1927, when KMT forces purged members of the rival Chinese Communist Party (CCP), who proceeded to engage in sporadic fighting against the KMT-led Nationalist government. Following the country's invasion by the Empire of Japan in 1937, the CCP and KMT formed the Second United Front to fight the Japanese. The Second Sino-Japanese War eventually ended in a Chinese victory; however, the CCP and the KMT resumed their civil war as soon as the war ended. In 1949, the resurgent Communists established control over most of the country, proclaiming the People's Republic of China and forcing the Nationalist government to retreat to the island of Taiwan. The country was split, with both sides claiming to be the sole legitimate government of China. Following the implementation of land reforms, further attempts by the PRC to realize communism failed: the Great Leap Forward was largely responsible for the Great Chinese Famine that ended with millions of Chinese people having died, and the subsequent Cultural Revolution was a period of social turmoil and persecution characterized by Maoist populism. Following the Sino-Soviet split, the Shanghai Communiqué in 1972 would precipitate the normalization of relations with the United States. Economic reforms that began in 1978 moved the country away from a socialist planned economy towards a market-based economy, spurring significant economic growth. A movement for increased democracy and liberalization stalled after the Tiananmen Square protests and massacre in 1989. (Full article...)
