The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America and consisting of 50 states, a federal district, five major unincorporated territories, and nine Minor Outlying Islands. It includes 326 Indian reservations. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third-most populous in the world. The national capital of the United States is Washington, D.C., and its most populous city and principal financial center is New York City.


Indigenous peoples have inhabited the Americas for thousands of years. Beginning in 1607, British colonization led to the establishment of the Thirteen Colonies in what is now the Eastern United States. They clashed with the British Crown over taxation and political representation which led to the American Revolution and the ensuing Revolutionary War. The United States declared independence on July 4, 1776, becoming the first nation-state founded on Enlightenment principles of unalienable natural rights, consent of the governed, and liberal democracy. The country began expanding across North America, spanning the continent by 1848. Sectional division over slavery led to the secession of the Confederate States of America, which fought the remaining states of the Union during the American Civil War (1861–1865). With the Union's victory and preservation, slavery was abolished nationally. By 1890, the United States had established itself as a great power, becoming the world's largest economy. After Japan's attack on Pearl Harbor in 1941, the U.S. entered World War II on the side of the Allies. The aftermath of the war left the United States and the Soviet Union as the world's two superpowers and led to the Cold War. During the Cold War, both countries engaged in a struggle for ideological dominance but avoided direct military conflict. They also competed in the Space Race, which culminated in the 1969 landing of Apollo 11, making the U.S. the only nation to land humans on the Moon. With the Soviet Union's collapse and the subsequent end of the Cold War in 1991, the United States emerged as the world's sole superpower.


The United States government is a federal republic and a representative democracy with three separate branches of government: executive, legislative, 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. Many policy issues are decentralized at a state or local level, with widely differing laws by jurisdiction. The U.S. ranks very highly in international measures of quality of life, income and wealth, economic competitiveness, human rights, innovation, and education; it has low levels of perceived corruption. It has higher levels of incarceration and inequality than most other liberal democracies, and is the only liberal democracy without universal healthcare. As a melting pot of cultures and ethnicities, the U.S. has been drastically shaped by the world's largest immigrant population. (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. 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 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.

Niger or the Niger (/niːˈʒɛər, ˈnaɪdʒər/ nee-ZHAIR, NY-jər, French: [niʒɛʁ]), officially the Republic of the Niger (French: République du Niger; Hausa: Jamhuriyar Nijar), is a landlocked country in West Africa. It is a unitary state bordered by Libya to the northeast, Chad to the east, Nigeria to the south, Benin and Burkina Faso to the southwest, Mali to the west, and Algeria to the northwest. It covers a land area of almost 1,270,000 km² (490,000 sq mi), making it the largest landlocked country in West Africa. Over 80% of its land area lies in the Sahara. Its predominantly Muslim population of about 25 million0 lives mostly in clusters in the south and west of the country. The capital Niamey is located in Niger's southwest corner.

Following the spread of Islam to the region, Niger was on the fringes of some states, including the Kanem–Bornu Empire and the Mali Empire before more significant parts of its territory became included in states such as the Sultanate of Agadez and the Songhai Empire. It was colonized by France during the Scramble for Africa as part of French West Africa, becoming a distinct colony in 1922. Since obtaining independence in 1960, Niger has experience five coups d'état and four periods of military rule. Niger's seventh and most recent constitution was enacted in 2010, establishing a multiparty, unitary semi-presidential system. Following the most recent coup in 2023, the country is once again under a military junta.

Its society reflects a diversity drawn from the independent histories of some ethnic groups and regions and their period living in a single state. The Hausa are the country's largest ethnic group, making up more than half the population. French is the country's official language, and ten indigenous languages have the status of national language. (Full article...)

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is an island country in Northwestern Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales, and Northern Ireland. It 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 93,628 square miles (242,495 km²), with an estimated 2023 population of over 68 million people.

The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which also included Wales) and the Kingdom of Scotland in 1707 resulted in their unification to become the Kingdom of Great Britain. Its union in 1801 with the Kingdom of Ireland created the United Kingdom of Great Britain and Ireland. Most of Ireland seceded from the UK in 1922, leaving the present United Kingdom of Great Britain and Northern Ireland, which formally adopted its name in 1927. The nearby Isle of Man, Guernsey and Jersey are not part of the UK, being Crown Dependencies, but the British government is responsible for their defence and international representation. 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, at its height in the 1920s, 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, the cumulative crisis and the loss of prestige led to the decolonization of most of the British colonies and the eventual end of the Empire. A part of the core Anglophonic world, British influence can be observed in the language, culture, legal and political systems of many of its former colonies. The UK's culture remains globally influential, particularly in literature, music and sport.

The United Kingdom is a constitutional monarchy and parliamentary democracy. The capital and largest city of the United Kingdom (as well as the capital of England) is London, a megacity which, alongside New York City, is one of the world's two leading financial centres. The cities of Edinburgh, Cardiff, and Belfast are respectively the national capitals of Scotland, Wales, and Northern Ireland. Other major cities include Birmingham, Manchester, Glasgow, and Leeds. The UK consists of three distinct legal jurisdictions: England and Wales, Scotland, and Northern Ireland. This is due to these areas retaining their existing legal systems even after joining the UK. Since 1998, Scotland, Wales, and Northern Ireland also have their own devolved governments and legislatures, each with varying powers. (Full article...)

Australia, officially the Commonwealth of Australia, is a sovereign 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 approximately 65,000 years ago, during the last ice age. Arriving by sea, 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 the European maritime exploration of Australia. The Dutch navigator Willem Janszoon was the first known European to reach Australia, in 1606. In 1770, the British explorer James Cook mapped and claimed the east coast of Australia for Great Britain, and the First Fleet of British ships arrived at Sydney in 1788 to establish the penal colony of New South Wales. The European population grew in subsequent decades, and by the end of the 1850s gold rush, most of the continent had been explored by European settlers and an additional five self-governing British colonies established. Democratic parliaments were gradually established through the 19th century, culminating with a vote for the federation of the six colonies and foundation of the Commonwealth of Australia on 1 January 1901. This began a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster Adoption Act 1942, and culminating in the Australia Act 1986.

Australia is a federal parliamentary constitutional monarchy, comprising six states and ten territories. Australia's 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 city and financial centre is Sydney. The next four largest cities are Melbourne, Brisbane, Perth, and Adelaide. It is ethnically diverse and multicultural, the product of large-scale immigration, with almost half of the population having at least one parent born overseas. Australia's abundant natural resources and well-developed international trade relations are crucial to the country's economy, which generates its income from various sources including services, mining exports, banking, manufacturing, agriculture and international education. Australia ranks highly for quality of life, health, education, economic freedom, civil liberties and political rights. (Full article...)

Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, making it the world's second-largest country by total area, with the world's longest coastline. Its border with the United States is the world's longest international land border. The country is characterized by a wide range of both meteorologic and geological regions. It is a sparsely inhabited country of 40 million people, the vast majority residing south of the 55th parallel in urban areas. Canada's capital is Ottawa and its three largest metropolitan areas are Toronto, Montreal, and Vancouver.

Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster, 1931, and culminating in the Canada Act 1982, which severed the vestiges of legal dependence on the Parliament of the United Kingdom.

Canada is a parliamentary democracy and a constitutional monarchy in the Westminster tradition. The country's head of government is the prime minister, who holds office by virtue of their ability to command the confidence of the elected House of Commons and is "called upon" by the governor general, representing the monarch of Canada, the head of state. The country is a Commonwealth realm and is officially bilingual (English and French) in the federal jurisdiction. It is very highly ranked in international measurements of government transparency, quality of life, economic competitiveness, innovation, education and gender equality. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration. Canada's long and complex relationship with the United States has had a significant impact on its history, economy, and culture. (Full article...)

China (Chinese: 中国; pinyin: Zhōngguó), officially the People's Republic of China (PRC), is a country in East Asia. It is the world's second-most populous country with a population exceeding 1.4 billion. China spans the equivalent of five time zones and borders fourteen countries by land, tied with Russia as having the most of any country in the world. With an area of nearly 9.6 million square kilometres (3,700,000 sq mi), it is the world's third largest country by total land area. The country is divided into 22 provinces, five autonomous regions, four municipalities, and two semi-autonomous special administrative regions. The national capital is Beijing, and the most populous city and largest financial center is Shanghai.

The region that is now China has been inhabited since the Paleolithic era. The earliest Chinese dynastic states, such as the Shang and the Zhou, emerged in the basin of the Yellow River before the late second millennium BCE. The eighth to third centuries BCE saw a breakdown in Zhou authority and significant conflict, as well as the emergence of Classical Chinese literature and philosophy. In 221 BCE, China was unified under an emperor, ushering in more than two millennia in which China was governed by one or more imperial dynasties, such as the Han, Tang, Ming and Qing. Some of China's most notable achievements, such as the invention of gunpowder and paper, the establishment of the Silk Road, and the building of the Great Wall, occurred during this period. The Chinese culture, including languages, traditions, architecture, philosophy and more, has heavily influenced East Asia during this imperial period.

In 1912, the Chinese monarchy was overthrown and the Republic of China established. The Republic saw consistent conflict for most of the mid-20th century, including a civil war between the Kuomintang government and the Chinese Communist Party (CCP), which began in 1927, as well as the Second Sino-Japanese War that began in 1937 and continued until 1945, therefore becoming involved in World War II. The latter led to a temporary stop in the civil war and numerous Japanese atrocities such as the Nanjing Massacre, which continue to influence China-Japan relations. In 1949, the CCP established control over China as the Kuomintang fled to Taiwan. Early communist rule saw two major projects: the Great Leap Forward, which resulted in a sharp economic decline and massive famine; and the Cultural Revolution, a movement to purge all non-communist elements of Chinese society that led to mass violence and persecution. Beginning in 1978, the Chinese government began economic reforms that moved the country away from planned economics, but political reforms were cut short by the 1989 Tiananmen Square protests, which ended in a massacre. Despite the event, the economic reform continued to strengthen the nation's economy in the following decades while raising China's standard of living significantly. (Full article...)

Russia (Russian: Россия, romanized: Rossiya, [rɐˈsʲijə]), or the Russian Federation, is a country spanning Eastern Europe and Northern Asia. It is the largest country in the world by area, extends across eleven time zones, and shares land boundaries with fourteen countries. It is the world's ninth-most populous country and Europe's most populous country. The country's capital and largest city is Moscow. Saint Petersburg is Russia's cultural centre and second-largest city. Other major urban areas in the country include Novosibirsk, Yekaterinburg, Nizhny Novgorod, Chelyabinsk, Krasnoyarsk, and Kazan.

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 neighbouring states, which have included the internationally unrecognised annexations of Crimea in 2014 from neighbouring Ukraine, followed by the further annexation of four other regions in 2022 during an ongoing invasion.

Japan (Japanese: 日本, [ɲihoɴ] ^ⓘ, Nippon or Nihon, and formally 日本国, Nippon-koku or Nihon-koku) 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 five main islands being Hokkaido, Honshu (the "mainland"), Shikoku, Kyushu, and Okinawa. Tokyo is the nation's capital and largest city, followed by Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto.

Japan has over 125 milion 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 the world's highest life expectancy, though it is experiencing a population decline due to its very low birth rate.

Japan has been inhabited since the Upper Paleolithic period (30,000 BC). Between the fourth and ninth centuries, the kingdoms of Japan 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.

Pakistan (Urdu: پَاکِسْتَان [ˈpaːkɪstaːn]), officially the Islamic Republic of Pakistan (ISO: اِسْلامیجَمْہُورِیَہ پَاکِسْتَان, islāmi jamhūriyāh pākistān), is a country in South Asia. It is the world's fifth-most populous country, with a population of 241.5 million people, and has the world's largest Muslim population as of 2023. Islamabad is the nation's capital, while Karachi is its largest city and financial centre, followed by Lahore, Faisalabad, Multan, Peshawar and Hyderabad. Pakistan is the 33rd-largest country in the world by area and the second largest in South Asia, spanning 881,913 square kilometres (340,509 square miles). It has a 1,046-kilometre (650-mile) coastline along the Arabian Sea and Gulf of Oman in the south, and is bordered by India to the east, Afghanistan to the west, Iran to the southwest, and China to the northeast. It is separated from Tajikistan by Afghanistan's narrow Wakhan Corridor in the north, and also shares a maritime border with Oman.

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 comprise 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 Samma, the Hindu Shahis, the Shah Miris, the Ghaznavids, the Delhi Sultanate, the Mughals, and most recently, the British Raj from 1858 to 1947.

Spurred by the Pakistan Movement, which sought a homeland for the Muslims of British India, and election victories in 1946 by the All-India Muslim League, Pakistan gained independence in 1947 after the Partition of the British Indian Empire, which awarded separate statehood to its Muslim-majority regions and was accompanied by an unparalleled mass migration and loss of life. Initially a Dominion of the British Commonwealth, Pakistan officially drafted its constitution in 1956, and emerged as a declared Islamic republic. In 1971, the exclave of East Pakistan seceded as the new country of Bangladesh after a nine-month-long civil war. In the following four decades, Pakistan has been ruled by governments whose descriptions, although complex, commonly alternated between civilian and military, democratic and authoritarian, relatively secular and Islamist. Pakistan elected a civilian government in 2008, and in 2010 adopted a parliamentary system with periodic elections. (Full article...)
