Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical rainforests in the north-east, tropical savannas in the north, and mountain ranges in the south-east.

The ancestors of Aboriginal Australians began arriving from south-east Asia 50,000 to 65,000 years ago, during the last glacial period. They settled the continent and had formed approximately 250 distinct language groups by the time of European settlement, maintaining some of the longest known continuing artistic and religious traditions in the world. Australia's written history commenced with European maritime exploration. The Dutch were the first known Europeans to reach Australia, in 1606. British colonisation began in 1788 with the establishment of the penal colony of New South Wales. By the mid-19th century, most of the continent had been explored by European settlers and five additional self-governing British colonies were established, each gaining responsible government by 1890. The colonies federated in 1901, forming the Commonwealth of Australia. This continued a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster Adoption Act 1942, and culminating in the Australia Acts of 1986.

Australia is a federal parliamentary constitutional monarchy comprising six states and ten territories: the states of New South Wales, Victoria, Queensland, Tasmania, South Australia and Western Australia; the major mainland Australian Capital Territory and Northern Territory; and other minor or external territories. Its population of nearly 27 million is highly urbanised and heavily concentrated on the eastern seaboard. Canberra is the nation's capital, while its most populous cities are Sydney, Melbourne, Brisbane, Perth and Adelaide, which each possess a population of at least one million inhabitants. Australian governments have promoted multiculturalism since the 1970s. Australia is culturally diverse and has one of the highest foreign-born populations in the world. Its abundant natural resources and well-developed international trade relations are crucial to the country's economy, which generates its income from various sources: predominantly services (including banking, real estate and international education) as well as mining, manufacturing and agriculture. It ranks highly for quality of life, health, education, economic freedom, civil liberties and political rights. (Full article...)

The United States of America (USA or U.S.A.), commonly known as the United States (US or U.S.) or America, is a country primarily located in North America. It is a federation of 50 states, a federal capital district (Washington, D.C.), and 326 Indian reservations. Outside the union of states, it asserts sovereignty over five major unincorporated island territories and various uninhabited islands. The country has the world's third-largest land area, second-largest exclusive economic zone, and third-largest population, exceeding 334 million.

Paleo-Indians migrated across the Bering land bridge more than 12,000 years ago, and went on to form various civilizations and societies. British colonization led to the first settlement of the Thirteen Colonies in Virginia in 1607. Clashes with the British Crown over taxation and political representation sparked the American Revolution, with the Second Continental Congress formally declaring independence on July 4, 1776. Following its victory in the Revolutionary War (1775–1783), the country continued to expand across North America. As more states were admitted, sectional division over slavery led to the secession of the Confederate States of America, which fought the remaining states of the Union during the 1861–1865 American Civil War. With the Union's victory and preservation, slavery was abolished nationally. By 1890, the United States had established itself as a great power. After Japan's attack on Pearl Harbor in December 1941, the U.S. entered World War II. The aftermath of the war left the U.S. and the Soviet Union as the world's two superpowers and led to the Cold War, during which both countries engaged in a struggle for ideological dominance and international influence. Following the Soviet Union's collapse and the end of the Cold War in 1991, the U.S. emerged as the world's sole superpower.

The U.S. national government is a presidential constitutional republic and liberal 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. Substantial autonomy is given to states and several territories, with a political culture that emphasizes liberty, equality under the law, individualism, and limited government. (Full article...)

India, officially the Republic of India (ISO: Bhārat Gaṇarājya), is a country in South Asia. It is the seventh-largest country by area; the most populous country as of June 2023; and from the time of its independence in 1947, the world's most populous democracy. It is physiographically bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, the Bay of Bengal on the southeast, and High-mountain Asia on the northeast. It shares land borders with Pakistan to the northwest; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of 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, initially in varying forms of isolation as hunter-gatherers, has made the region highly diverse, second only to Africa in human genetic diversity. 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 evidence today is found in the hymns of the Rigveda. Preserved by an oral tradition that was resolutely vigilant, the Rigveda records the dawning of Hinduism in India. The Dravidian languages of India were supplanted in the northern and western regions.
By 400 BCE, stratification and exclusion by 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 based in the Ganges Basin.
Their collective era was suffused with wide-ranging creativity, but also marked by the declining status of women, and the incorporation of untouchability into an organised system of belief. In South India, the Middle kingdoms exported Dravidian-languages 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,
eventually founding the Delhi Sultanate, and drawing northern India into the cosmopolitan networks of medieval Islam.
In the 15th century, the Vijayanagara Empire created a long-lasting composite Hindu culture in south India.
In the Punjab, Sikhism emerged, rejecting institutionalised religion.
The Mughal Empire, in 1526, ushered in two centuries of relative peace,
leaving a legacy of luminous architecture.
Gradually expanding rule of the British East India Company followed, turning India into a colonial economy, but also consolidating 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 pioneering and influential nationalist movement emerged, which was noted for nonviolent resistance and became the major 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, amid large-scale loss of life and an unprecedented migration.

Iran, officially the Islamic Republic of Iran (IRI), also known by its Western-given name Persia, is a country in West Asia. It borders Turkey to the northwest and Iraq to the west, Azerbaijan, Armenia, the Caspian Sea and Turkmenistan to the north, Afghanistan to the east, Pakistan to the southeast, the Gulf of Oman and the Persian Gulf to the south. With a mostly Persian-ethnic population of almost 90 million in an area of 1,648,195 km² (636,372 sq mi), Iran ranks 17th globally in both geographic size and population. It is the sixth-largest country entirely in Asia, the second-largest in West Asia, and one of the world's most mountainous countries. Officially an Islamic republic, Iran has a Muslim-majority population. The country is divided into five regions with 31 provinces. Tehran is the nation's capital, largest city and financial center with around 16.8 million people in its metropolitan area. Other major cities include Mashhad, Isfahan, Karaj, and Shiraz.

A cradle of civilization, Iran has been inhabited since the Lower Palaeolithic, with one of the longest histories of any country. It was unified as a state for the first time by Deioces in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great founded the Achaemenid Empire, one of the largest in ancient history. Alexander the Great conquered the empire in the fourth century BC, dividing Iran into Hellenistic states. An Iranian rebellion established the Parthian Empire in the third century BC and liberated the country, which was succeeded by the Sasanian Empire in the third century AD. Ancient Iran saw some of the earliest developments of writing, agriculture, urbanisation, religion and central government. Muslims conquered the region in the seventh century AD, leading to Iran's Islamization. The blossoming literature, philosophy, mathematics, medicine, astronomy and art became major elements for Iranian civilization during the Islamic Golden Age, and Iran was the main theatre of scientific activities. A series of Iranian Muslim dynasties ended Arab rule, revived the Persian language and ruled the country until the Seljuk and Mongol conquests of the 11th to 14th centuries. In the 16th century, the native Safavids re-established a unified Iranian state with Twelver Shia Islam as the official religion, marking the beginning of modern Iranian history.

During the Afsharid Empire in the 18th century, Iran was a leading world power, though by the 19th century, it had lost significant territory through conflicts with the Russian Empire. The early 20th century saw the Persian Constitutional Revolution and the establishment of the Pahlavi dynasty. Attempts by Mohammad Mosaddegh to nationalize the country's vast fossil fuel supply led to an Anglo-American coup in 1953. After the Iranian Revolution, the monarchy was overthrown in 1979 and the Islamic Republic of Iran was established by The Grand Ayatollah Ruhollah Khomeini, who became the country's first Supreme Leader. The forces of Saddam Hussein invaded in 1980, initiating the 8-year-long Iran-Iraq War. Iran is officially governed as an Islamic Republic with a Presidential system, with ultimate authority vested in a Supreme Leader, currently Ali Khamenei since Khomeini's death in 1989. The government is authoritarian and has attracted widespread criticism for its significant violations of human rights and civil liberties. (Full article...)

Palestine (Arabic: فلسطين, romanized: Filasṭīn), officially the State of Palestine (دولة فلسطين, Dawlat Filasṭīn), is a country in the southern Levant region of West Asia. It encompasses two disconnected territories — the West Bank and the Gaza Strip, collectively known as the Palestinian territories — within the larger region of Palestine. The country shares its borders with Israel to north, west and south, Jordan to the east and Egypt to the southwest. It has a combined land area of 6,020 square kilometres (2,320 sq mi) while its population exceeds five million people. Its proclaimed capital is Jerusalem while Ramallah serves as its administrative center and Gaza City was its largest city until massive population movements began in 2023 due to the Israeli invasion of the Gaza Strip. Arabic is the official language. The majority of Palestinians practice Islam while Christianity also has a significant presence.

The region of Palestine has played an important part in world history. The Canaanites, Israelites, Assyrians, Babylonians, Persians, Greeks, Romans and Byzantines all left their mark on the land. In addition to its historical significance, Palestine holds profound religious importance for Judaism, Christianity and Islam. Throughout history the region has experienced periods of coexistence and conflict between different religious and ethnic groups. Notably, during the Middle Ages, when Jewish communities faced persecution, they found refuge and protection under Muslim rule and the wider Islamic world. The Ottoman Empire, which controlled Palestine from the 16th century until its collapse at the end of World War I, provided a sanctuary for Jews fleeing persecution in Europe. The end of Ottoman rule marked a new chapter in Palestine's history. Following World War I, the British Empire assumed control of the region under the League of Nations mandate. The British Mandate for Palestine, established in 1920, brought significant changes to the political and social landscape of the area, setting the stage for the conflicts and struggles that would follow.

The establishment of the State of Israel in 1948 was accompanied by a war which led to the forced displacement of 700,000 Palestinians and created a large refugee population. Subsequent Arab–Israeli wars, including the Six-Day War in 1967, resulted in the Israeli occupation of the West Bank and the Gaza Strip. On 15th November 1988, Palestinian National Council, the legislative body of the Palestine Liberation Organization (PLO) led by Yasser Arafat, declared the establishment of the State. Signing of the Oslo Accords in the 1990s, negotiated between Israel and the PLO, created the Palestinian Authority (PA) to exercise partial control over parts of Palestinian territories. In 2007, internal divisions between Palestinian political factions led to a takeover of the Gaza Strip by Hamas. Since then, the West Bank has been governed in part by the Palestinian Authority, led by Fatah, while the Gaza Strip has remained under the control of Hamas. Israel has built settlements in both of the Palestinian territories since the start of the occupation. The settlements in the Gaza Strip were dismantled in Israel's unilateral disengagement in 2005, and approximately 670,000 Israeli settlers live in settlements in the West Bank. The international community considers Israeli settlements in Palestinian territories illegal under international law, but the Israeli government disputes this. (Full article...)

Israel, officially the State of Israel, is a country in the Southern Levant, West Asia. It is bordered by Lebanon and Syria to the north, the West Bank and Jordan to the east, Egypt, the Gaza Strip and the Red Sea to the south, and the Mediterranean Sea to the west. Tel Aviv is the country's largest city as well as its economic center. While Israel's governmental seat is in its self-proclaimed capital of Jerusalem, though recognition of Israeli sovereignty over East Jerusalem is limited internationally.

Israel is in a region known historically as Canaan, Palestine, and the Holy Land. In antiquity, it was home to Canaanite city-states, then Israelite and Judahite kingdoms, and is referred to as the Land of Israel in Jewish tradition. Situated at a continental crossroad, the region was then ruled by various empires. Amid European antisemitism, the late 19th century saw the rise of Zionism, which sought a Jewish homeland. British occupation led to the establishment of Mandatory Palestine in 1920. Jewish immigration, combined with British colonial policy, led to intercommunal conflict between Jews and Arabs. The 1947 UN Partition Plan triggered civil war between them.

The State of Israel declared its establishment on 14 May 1948. The next day, armies of neighboring Arab states invaded, starting the First Arab–Israeli War. The Palestinians were expelled or made to flee, by paramilitaries and later its military, an expulsion known as the Nakba. Over the following decades, Israel received an influx of immigration from Jews who emigrated, fled, or were expelled from the Muslim world. The 1949 Armistice Agreements established Israel's borders over most of the former Mandate territory. The 1967 Six-Day War saw Israel occupy the West Bank, Gaza Strip, Egyptian Sinai Peninsula and Syrian Golan Heights. Israel has established and continues to expand settlements across the occupied territories, which is deemed illegal under international law, and has annexed East Jerusalem and the Golan Heights, which is largely unrecognized internationally. Since the 1973 Yom Kippur War, Israel has signed peace treaties with Egypt, returning the Sinai Peninsula, and Jordan, and into the 2020s has normalized relations with several Arab countries. However, efforts to resolve the Israeli–Palestinian conflict have not succeeded. Israel has been internationally criticised in its occupation of the Palestinian territories, and been accused of committing war crimes and crimes against humanity against the Palestinians by human rights organizations and UN officials.

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Northwestern 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. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea, and the Irish Sea. The total area of the United Kingdom is 94,354 square miles (244,376 km²), with an estimated population of nearly 67.6 million people in 2022.

In 1707, the Kingdom of England (which included Wales) and the Kingdom of Scotland united under the Treaty of Union to create the Kingdom of Great Britain. 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 name, the United Kingdom of Great Britain and Northern Ireland.

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. At its height in the 1920s, the British 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. British influence can be observed in the legal and political systems of many of its former colonies, and British culture remains globally influential, particularly in language, literature, music and sport. English is the world's most widely spoken language and the third-most spoken native language. (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 world's second-most populous country after India and contains 17.4% of the world population. China spans the equivalent of five time zones and borders fourteen countries by land. With an area of nearly 9.6 million square kilometers (3,700,000 sq mi), it is the third-largest country by total land area. The country is divided into 33 province-level divisions: 22 provinces, five autonomous regions, four municipalities, and two 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.

A cradle of civilization, China has been inhabited since the Paleolithic era, with the earliest dynasties emerging in the Yellow River basin before the late second millennium BCE. The eighth to third 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 for the first time. Appointed non-hereditary officials began ruling counties instead of the aristocracy, 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—including languages, traditions, architecture, philosophy and technology—flourished and has heavily influenced East Asia and beyond. 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 struggle, the monarchy was overthrown in 1912 and the Republic of China (ROC) was formed, although the country in the Beiyang era became unstable which resulted in the Warlord Era, that later concluded after the Kuomintang (KMT) reunified the country while the Chinese Communist Party (CCP), purged after 1927, were fighting sporadically against the Nationalist government, with a brief truce as a united front when Japan began invading the country. Despite China's eventual victory in the Second Sino-Japanese War and the Pacific War in general, numerous atrocities such as the Nanjing Massacre left lasting effects on the country. After the war ended, it recovered the territories that Japan annexed but the second phase of the Chinese Civil War resumed shortly after, and by 1949, the CCP had established control on most of the territories of the country. As the KMT retreated to the island of Taiwan, the country was split with both sides claiming to be the sole legitimate government of China. After the land reforms, later attempts to realize communism failed—the Great Leap Forward led to a massive famine of millions of citizens, while the Cultural Revolution caused a chaotic period of persecution and zealous Maoist populism. In 1971, the PRC replaced the ROC as China's representation in the United Nations (UN). Following the Sino-Soviet split, the Shanghai Communiqué in 1972 marked the beginning of normalized relations with the United States. Economic reforms that began in 1978 led by reformists within the CCP moved the country away from a socialist planned economy toward an increasingly capitalist market economy, spurring significant economic growth, although liberal and democratic political reforms stalled after the Tiananmen Square massacre in 1989.

Russia, or the Russian Federation, is a country spanning Eastern Europe and North Asia. It is the largest country in the world by area, extending across eleven time zones and sharing land borders with fourteen countries. It is the world's ninth-most populous country and Europe's most populous country. Russia is a highly urbanized country including 16 population centers with over a million inhabitants. Its capital as well as its largest city is Moscow. Saint Petersburg is Russia's second-largest city and its cultural capital.

The East Slavs emerged as a recognised group in Europe between the 3rd and 8th centuries CE. The first East Slavic state, Kievan Rus', arose in the 9th century, and in 988, it adopted Orthodox Christianity from the Byzantine Empire. Rus' ultimately disintegrated, with the Grand Duchy of Moscow growing to become the Tsardom of Russia. By the early 18th century, Russia had vastly expanded through conquest, annexation, and the efforts of Russian explorers, developing into the Russian Empire, which remains the third-largest empire in history. However, with the Russian Revolution in 1917, Russia's monarchic rule was abolished and eventually replaced by the Russian SFSR—the world's first constitutionally socialist state. Following the Russian Civil War, the Russian SFSR established the Soviet Union with three other Soviet republics, within which it was the largest and principal constituent. At the expense of millions of lives, the Soviet Union underwent rapid industrialisation in the 1930s and later played a decisive role for the Allies in World War II by leading large-scale efforts on the Eastern Front. With the onset of the Cold War, it competed with the United States for global ideological influence. The Soviet era of the 20th century saw some of the most significant Russian technological achievements, including the first human-made satellite and the first human expedition into outer space.

In 1991, the Russian SFSR emerged from the dissolution of the Soviet Union as the independent Russian Federation. A new constitution was adopted, which established a federal semi-presidential system. Since the turn of the century, Russia's political system has been dominated by Vladimir Putin, under whom the country has experienced democratic backsliding and a shift towards authoritarianism. Russia has been militarily involved in a number of conflicts in former Soviet states and other countries, including its war with Georgia in 2008 and annexation of Crimea in 2014 from neighbouring Ukraine, followed by the further annexation of four other regions in 2022 during an ongoing invasion.

Japan is an island country in East Asia. It is in the northwest Pacific Ocean and is bordered on the west by the Sea of Japan, extending from the Sea of Okhotsk in the north toward the East China Sea, Philippine Sea, and Taiwan in the south. Japan is a part of the Ring of Fire, and spans an archipelago of 14,125 islands, with the four main islands being Hokkaido, Honshu (the "mainland"), Shikoku, and Kyushu. Tokyo is the country's capital and largest city, followed by Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto.

The Japanese archipelago has been inhabited since the Upper Paleolithic (30,000 BC). Between the fourth and ninth centuries AD, the kingdoms of the region became unified under an emperor and the imperial court based in Heian-kyō. Beginning in the 12th century, political power was held by a series of military dictators (shōgun) and feudal lords (daimyō), and enforced by a class of warrior nobility (samurai). After a century-long period of civil war, the country was reunified in 1603 under the Tokugawa shogunate, which enacted an isolationist foreign policy. In 1854, a United States fleet forced Japan to open trade to the West, which led to the end of the shogunate and the restoration of imperial power in 1868. In the Meiji period, the Empire of Japan adopted a Western-modeled constitution, and pursued a program of industrialization and modernization. Amidst a rise in militarism and overseas colonization, Japan invaded China in 1937 and entered World War II as an Axis power in 1941. After suffering defeat in the Pacific War and two atomic bombings, Japan surrendered in 1945 and came under a seven-year Allied occupation, during which it adopted a new constitution.

Under the 1947 constitution, Japan has maintained a constitutional monarchy with a bicameral legislature, the National Diet. Japan is a highly developed country and a great power, with one of the largest economies by nominal GDP. Japan has renounced its right to declare war, though it maintains a self-defense force that ranks as one of the world's strongest militaries. A global leader in the automotive, robotics, and electronics industries, the country has made significant contributions to science and technology, and is one of the world's largest exporters and importers. It is part of multiple major international and intergovernmental institutions. Japan has over 125 million inhabitants and is the 11th most populous country in the world, as well as one of the most densely populated. About three-fourths of the country's terrain is mountainous, concentrating its highly urbanized population on narrow coastal plains. Japan is divided into 47 administrative prefectures and eight traditional regions. The Greater Tokyo Area is the most populous metropolitan area in the world. Japan has one of the world's longest life expectancies but is experiencing a population decline due to its very low birth rate. A cultural superpower, Japan's culture is well known around the world, including its art, cuisine, film, music, and popular culture, which encompasses prominent manga, anime, and video game industries.
