Introduction to the United Kingdom


The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain,is a sovereign country in north-western Europe, off the north-­western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-­eastern part of the island of Ireland, and many 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, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world. The Irish Sea separates Great Britain and Ireland. The total area of the United Kingdom is 93,628 square miles (242,500 km2).

The United Kingdom is a unitary parliamentary democracy and constitutional monarchy. The monarch, Queen Elizabeth II, has reigned since 1952. The capital is London, a global city and financial centre with an urban area population of 10.3 million. The United Kingdom consists of four countries: England, Scotland, Wales and Northern Ireland. Their capitals are London, Edinburgh, Cardiff and Belfast, respectively. Other than England, the constituent countries have their own devolved governments, each with varying powers.

The union between the Kingdom of England (which included Wales) and the Kingdom of Scotland in 1707 to form the Kingdom of Great Britain, followed by their 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 formulation of the United Kingdom of Great Britain and Northern Ireland, which formally adopted the name in 1927 to reflect the change.

The nearby Isle of Man, Guernsey and Bailiwick of Jersey are not part of the UK, being Crown Dependencies with the British Government responsible for defence and international representation. There are also 14 British Overseas Territories,the last remnants of the British Empire which, at its height in the 1920s, encompassed almost a quarter of the world's landmass and a third of the world's population, and was the largest empire in history. British influence can be observed in the language, culture and the legal and political systems of many of its former colonies.

The United Kingdom has the world's fifth-largest economy by nominal gross domestic product (GDP), and the tenth-largest by purchasing power parity (PPP). It has a high-income economy and a very high human development index rating, ranking 13th in the world. The UK became the world's first industrialised country and was the world's foremost power during the 19th and early 20th centuries. Today the UK remains one of the world's great powers, with considerable economic, cultural, military, scientific, technological and political influence internationally.It is a recognised nuclear weapon state and is ranked sixth globally in military expenditure. It has been a permanent member of the United Nations Security Council since its first session in 1946.

The United Kingdom is a member of the Commonwealth of Nations, the Council of Europe, the G7, the G20, NATO, the Organisation for Economic Co-operation and Development (OECD), Interpol and the World Trade Organization (WTO). It was a member of the European Union (EU) and its predecessor, the European Economic Community (EEC), from 1973 until withdrawing in 2020.

Introduction to China


China (Chinese: 中国; pinyin: Zhōngguó; lit. 'Central State; Middle Kingdom'), officially the People's Republic of China (Chinese: 中华人民共和国; pinyin: Zhōnghuá Rénmín Gònghéguó; PRC), is a country in East Asia. It is the world's most populous country, with a population of more than 1.4 billion. It borders 14 countries, the second most of any country in the world, after Russia. Covering an area of approximately 9.6 million square kilometers (3.7 million mi2), it is the world's third or fourth largest country.[k] The country is officially divided into 23 provinces,[l] five autonomous regions, and four direct-controlled municipalities of Beijing (the capital city), Tianjin, Shanghai (the largest city), and Chongqing, as well as two special administrative regions of Hong Kong and Macau.

China emerged as one of the world's first civilizations, in the fertile basin of the Yellow River in the North China Plain. China was one of the world's foremost economic powers for most of the two millennia from the 1st until the 19th century. For millennia, China's political system was based on absolute hereditary monarchies, or dynasties, beginning with the Xia dynasty in 21st century BCE. Since then, China has expanded, fractured, and re-unified numerous times. In the 3rd century BCE, the Qin reunited core China and established the first Chinese empire. The succeeding Han dynasty (206 BCE–220 CE) saw some of the most advanced technology at that time, including papermaking and the compass, along with agricultural and medical improvements. The invention of gunpowder and movable type in the Tang dynasty (618–907) and Northern Song Dynasty (960–1127) completed the Four Great Inventions. Tang culture spread widely in Asia, as the new Silk Route brought traders to as far as Mesopotamia and the Horn of Africa. The Qing Empire, China's last dynasty, which formed the territorial basis for modern China suffered heavy losses to foreign imperialism. The Chinese monarchy collapsed in 1912 with the 1911 Revolution, when the Republic of China (ROC) replaced the Qing dynasty. China was invaded by the Empire of Japan during World War II. The Chinese Civil War resulted in a division of territory in 1949 when the Chinese Communist Party (CCP) led by Mao Zedong established the People's Republic of China on mainland China while the Kuomintang-led ROC government retreated to the island of Taiwan.[m] Both the PRC and the ROC currently claim to be the sole legitimate government of China, resulting in an ongoing dispute even after the United Nations recognized the PRC as the government to represent China at all UN conferences in 1971.

China is nominally a unitary one-party socialist republic. The country is a permanent member of the United Nations Security Council and a founding member of several multilateral and regional cooperation organizations such as the Asian Infrastructure Investment Bank, the Silk Road Fund, the New Development Bank, the Shanghai Cooperation Organization, and the Regional Comprehensive Economic Partnership, and is a member of the BRICS, the G8+5, the G20, the APEC, and the East Asia Summit. It ranks among the lowest in international measurements of civil liberties, government transparency, freedom of the press, freedom of religion and ethnic minorities. Chinese authorities have been criticized by political dissidents and human rights activists for widespread human rights abuses, including political repression, mass censorship, mass surveillance of their citizens and violent suppression of protests.

After economic reforms in 1978, and its entry into the World Trade Organization in 2001, China's economy became the second-largest country by nominal GDP in 2010 and grew to the largest in the world by PPP in 2014. China is the world's fastest-growing major economy, the second-wealthiest nation in the world, and the world's largest manufacturer and exporter. The nation has the world's largest standing army — the People's Liberation Army — the second-largest defense budget and is a recognized nuclear weapons state. China has been characterized as a potential superpower due to its large economy and powerful military.

Introduction to India

India, officially the Republic of India (Hindi: Bhārat Gaṇarājya),is a country in South Asia. It is the second-most populous country, the seventh-largest country by land area, and the most populous democracy in the world. 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;[f] 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.[25] 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, unfolding as the language of the Rigveda, and recording the dawning of Hinduism in India.[28] 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,[34] 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 put down roots on India's southern and western coasts. Muslim armies from Central Asia intermittently overran India's northern plains,eventually establishing 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 ideas of education, modernity 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. India has been a federal republic since 1950, governed in a democratic parliamentary system. It is a pluralistic, multilingual and multi-ethnic society. India's population grew from 361 million in 1951 to 1.211 billion in 2011.During the same time, its nominal per capita income increased from US$64 annually to US$1,498, and its literacy rate from 16.6% to 74%. From being a comparatively destitute country in 1951,India has become a fast-growing major economy and a hub for information technology services, with an expanding middle class.It has a space programme which includes several planned or completed extraterrestrial missions. Indian movies, music, and spiritual teachings play an increasing role in global culture. India has substantially reduced its rate of poverty, though at the cost of increasing economic inequality. India is a nuclear-weapon state, which ranks high in military expenditure. It has disputes over Kashmir with its neighbours, Pakistan and China, unresolved since the mid-20th century. Among the socio-economic challenges India faces are gender inequality, child malnutrition, and rising levels of air pollution. India's land is megadiverse, with four biodiversity hotspots.Its forest cover comprises 21.7% of its area. India's wildlife, which has traditionally been viewed with tolerance in India's culture, is supported among these forests, and elsewhere, in protected habitats.

Introduction to Japan

Japan (Japanese: 日本, Nippon [ɲippoꜜɴ] (About this soundlisten) or Nihon [ɲihoꜜɴ] (About this soundlisten)) is an island country in East Asia, located in the northwest Pacific Ocean. It is bordered on the west by the Sea of Japan, and extends from the Sea of Okhotsk in the north toward the East China Sea and Taiwan in the south. Part of the Ring of Fire, Japan spans an archipelago of 6852 islands covering 377,975 square kilometers (145,937 sq mi); the five main islands are Hokkaido, Honshu, Shikoku, Kyushu, and Okinawa. Tokyo is Japan's capital and largest city; other major cities include Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto. Japan is the eleventh-most populous country in the world, as well as one of the most densely populated and urbanized. About three-fourths of the country's terrain is mountainous, concentrating its population of 125.47 million 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, with more than 37.4 million residents. Japan has been inhabited since the Upper Paleolithic period (30,000 BC), though the first written mention of the archipelago appears in a Chinese chronicle finished in the 2nd century AD. Between the 4th and 9th 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. In 1937, Japan invaded China; in 1941, it entered World War II as an Axis power. 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 unitary parliamentary constitutional monarchy with a bicameral legislature, the National Diet. Japan is a great power and a member of numerous international organizations, including the United Nations (since 1956), the OECD, and the Group of Seven. Although it has renounced its right to declare war, the country maintains Self-Defense Forces that rank as one of the world's strongest militaries. After World War II, Japan experienced record growth in an economic miracle, becoming the second-largest economy in the world by 1990. As of 2021, the country's economy is the third-largest by nominal GDP and the fourth-largest by PPP. A global leader in the automotive and electronics industries, Japan has made significant contributions to science and technology. Ranked "very high" on the Human Development Index, Japan has the world's highest life expectancy, though it is experiencing a decline in population. The culture of Japan is well known around the world, including its art, cuisine, music, and popular culture, which encompasses prominent comic, animation and video game industries.
