Lesotho the Kingdom of Lesotho, is an enclaved country–the only one in the world outside of the Italian peninsula–within the border of South Africa. It has a population of around 2 million, its capital and largest city is Maseru. Lesotho was the British Crown Colony of Basutoland, but it declared independence from the United Kingdom on 4 October 1966, it is now a sovereign state, a member of the United Nations, the Commonwealth of Nations, the Southern African Development Community. The name Lesotho translates to "the land of the people who speak Sesotho"; the original inhabitants of the area now known as Lesotho were the San people. Examples of their rock art can be found in the mountains throughout the area; the present Lesotho called Basutoland, emerged as a single polity under King Moshoeshoe I in 1822. Moshoeshoe, a son of Mokhachane, a minor chief of the Bakoteli lineage, formed his own clan and became a chief around 1804. Between 1821 and 1823, he and his followers settled at the Butha-Buthe Mountain, joining with former adversaries in resistance against the Lifaqane associated with the reign of Shaka Zulu from 1818 to 1828.
Subsequent evolution of the state hinged on conflicts between British and Dutch colonists leaving the Cape Colony following its seizure from the French-allied Dutch by the British in 1795, subsequently associated with the Orange River Sovereignty and subsequent Orange Free State. Missionaries invited by Moshoeshoe I, Thomas Arbousset, Eugène Casalis and Constant Gosselin from the Paris Evangelical Missionary Society, placed at Morija, developed orthography and printed works in the Sesotho language between 1837 and 1855. Casalis, acting as translator and providing advice on foreign affairs, helped to set up diplomatic channels and acquire guns for use against the encroaching Europeans and the Griqua people. Trekboers from the Cape Colony arrived on the western borders of Basutoland and claimed land rights, beginning with Jan de Winnaar, who settled in the Matlakeng area in May–June 1838; as more Boers were moving into the area they tried to colonise the land between the two rivers north of the Caledon, claiming that it had been abandoned by the Sotho people.
Moshoeshoe subsequently signed a treaty with the British Governor of the Cape Colony, Sir George Thomas Napier, that annexed the Orange River Sovereignty that many Boers had settled. These outraged Boers were suppressed in a brief skirmish in 1848. In 1851 a British force was defeated by the Basotho army at Kolonyama, touching off an embarrassing war for the British. After repelling another British attack in 1852, Moshoeshoe sent an appeal to the British commander that settled the dispute diplomatically defeated the Batlokoa in 1853. In 1854 the British pulled out of the region, in 1858 Moshoeshoe fought a series of wars with the Boers in the Free State–Basotho War, losing a great portion of the western lowlands; the last war in 1867 ended when Moshoeshoe appealed to Queen Victoria, who agreed to make Basutoland a British protectorate in 1868. In 1869, the British signed a treaty at Aliwal North with the Boers that defined the boundaries of Basutoland, Lesotho, which by ceding the western territories reduced Moshoeshoe's Kingdom to half its previous size.
Following the cession in 1869, the British transferred functions from Moshoeshoe's capital in Thaba Bosiu to a police camp on the northwest border, until administration of Basutoland was transferred to the Cape Colony in 1871. Moshoeshoe died on 11 March 1870, marking the end of the traditional era and the beginning of the colonial era, he was buried at Thaba Bosiu. In the early years of British rule between 1871 and 1884, Basutoland was treated to other territories, forcibly annexed, much to the chagrin of the Basotho; this led to the Gun War in 1881. In 1884, Basutoland was restored to its status as a protectorate, with Maseru again its capital, but remained under direct rule by a governor, though effective internal power was wielded by traditional chiefs. Basutoland gained its independence from Britain and became the Kingdom of Lesotho in 1966. In January 1970, the ruling Basotho National Party lost the first post-independence general elections, with 23 seats to the Basutoland Congress Party's 36.
Prime Minister Leabua Jonathan refused to cede power to the Basotho Congress Party, declared himself Tona Kholo, imprisoned the BCP leadership. BCP began a rebellion and received training in Libya for its Lesotho Liberation Army under the pretense of being Azanian People's Liberation Army soldiers of the Pan Africanist Congress. Deprived of arms and supplies by the Sibeko faction of the PAC in 1978, the 178-strong LLA was rescued from their Tanzanian base by the financial assistance of a Maoist PAC officer, but they launched the guerrilla war with only a handful of old weapons; the main force was defeated in northern Lesotho, guerrillas launched sporadic but ineffectual attacks. The campaign was compromised when BCP's leader, Ntsu Mokhehle, went to Pretoria. In the early 1980s, several Basotho who sympathised with the exiled BCP were threatened with death and attacked by the government of Leabua Jonathan. On 4 September 1981, the family of Benjamin Masilo was attacked. In the attack his 3-year-old grandson lost his life.
Four days Edgar Mahlomola Motuba, the editor of the popular newspaper Leselinyana la Lesotho, was abducted from his home together with two friends and murdered. The BNP ruled from 1966 until January 1970. What ensued was a de facto government led by Dr. Leab
South America is a continent in the Western Hemisphere in the Southern Hemisphere, with a small portion in the Northern Hemisphere. It may be considered a subcontinent of the Americas, how it is viewed in the Spanish and Portuguese-speaking regions of the Americas; the reference to South America instead of other regions has increased in the last decades due to changing geopolitical dynamics. It is bordered on the west on the north and east by the Atlantic Ocean, it includes twelve sovereign states, a part of France, a non-sovereign area. In addition to this, the ABC islands of the Kingdom of the Netherlands and Tobago, Panama may be considered part of South America. South America has an area of 17,840,000 square kilometers, its population as of 2016 has been estimated at more than 420 million. South America ranks fourth in fifth in population. Brazil is by far the most populous South American country, with more than half of the continent's population, followed by Colombia, Argentina and Peru. In recent decades Brazil has concentrated half of the region's GDP and has become a first regional power.
Most of the population lives near the continent's western or eastern coasts while the interior and the far south are sparsely populated. The geography of western South America is dominated by the Andes mountains. Most of the continent lies in the tropics; the continent's cultural and ethnic outlook has its origin with the interaction of indigenous peoples with European conquerors and immigrants and, more locally, with African slaves. Given a long history of colonialism, the overwhelming majority of South Americans speak Portuguese or Spanish, societies and states reflect Western traditions. South America occupies the southern portion of the Americas; the continent is delimited on the northwest by the Darién watershed along the Colombia–Panama border, although some may consider the border instead to be the Panama Canal. Geopolitically and geographically all of Panama – including the segment east of the Panama Canal in the isthmus – is included in North America alone and among the countries of Central America.
All of mainland South America sits on the South American Plate. South America is home to Angel Falls in Venezuela. South America's major mineral resources are gold, copper, iron ore and petroleum; these resources found in South America have brought high income to its countries in times of war or of rapid economic growth by industrialized countries elsewhere. However, the concentration in producing one major export commodity has hindered the development of diversified economies; the fluctuation in the price of commodities in the international markets has led to major highs and lows in the economies of South American states causing extreme political instability. This is leading to efforts to diversify production to drive away from staying as economies dedicated to one major export. South America is one of the most biodiverse continents on earth. South America is home to many interesting and unique species of animals including the llama, piranha, vicuña, tapir; the Amazon rainforests possess high biodiversity, containing a major proportion of the Earth's species.
Brazil is the largest country in South America, encompassing around half of the continent's land area and population. The remaining countries and territories are divided among three regions: The Andean States, the Guianas and the Southern Cone. Traditionally, South America includes some of the nearby islands. Aruba, Curaçao, Trinidad and the federal dependencies of Venezuela sit on the northerly South American continental shelf and are considered part of the continent. Geo-politically, the island states and overseas territories of the Caribbean are grouped as a part or subregion of North America, since they are more distant on the Caribbean Plate though San Andres and Providencia are politically part of Colombia and Aves Island is controlled by Venezuela. Other islands that are included with South America are the Galápagos Islands that belong to Ecuador and Easter Island, Robinson Crusoe Island, Chiloé and Tierra del Fuego. In the Atlantic, Brazil owns Fernando de Noronha and Martim Vaz, the Saint Peter and Saint Paul Archipelago, while the Falkland Islands are governed by the United Kingdom, whose sovereignty over the islands is disputed by Argentina.

North America is a continent within the Northern Hemisphere and all within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16.5% of the earth's land area and about 4.8% of its total surface. North America is the third largest continent by area, following Asia and Africa, the fourth by population after Asia and Europe. In 2013, its population was estimated at nearly 579 million people in 23 independent states, or about 7.5% of the world's population, if nearby islands are included. North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge 40,000 to 17,000 years ago; the so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago. The Classic stage spans the 6th to 13th centuries.
The Pre-Columbian era ended in 1492, the transatlantic migrations—the arrival of European settlers during the Age of Discovery and the Early Modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, African slaves and their descendants. Owing to the European colonization of the Americas, most North Americans speak English, Spanish or French, their culture reflects Western traditions; the Americas are accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass unknown by Europeans. In 1507, Waldseemüller produced a world map, in which he placed the word "America" on the continent of South America, in the middle of what is today Brazil, he explained the rationale for the name in the accompanying book Cosmographiae Introductio:... ab Americo inventore... quasi Americi terram sive Americam.
For Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespucci's name, but in its feminine form "America", following the examples of "Europa", "Asia" and "Africa". Other mapmakers extended the name America to the northern continent, In 1538, Gerard Mercator used America on his map of the world for all the Western Hemisphere; some argue that because the convention is to use the surname for naming discoveries, the derivation from "Amerigo Vespucci" could be put in question. In 1874, Thomas Belt proposed a derivation from the Amerrique mountains of Central America. Marcou corresponded with Augustus Le Plongeon, who wrote: "The name AMERICA or AMERRIQUE in the Mayan language means, a country of perpetually strong wind, or the Land of the Wind, and... the can mean... a spirit that breathes, life itself." The United Nations formally recognizes "North America" as comprising three areas: Northern America, Central America, The Caribbean.
This has been formally defined by the UN Statistics Division. The term North America maintains various definitions in accordance with context. In Canadian English, North America refers to the land mass as a whole consisting of Mexico, the United States, Canada, although it is ambiguous which other countries are included, is defined by context. In the United States of America, usage of the term may refer only to Canada and the US, sometimes includes Greenland and Mexico, as well as offshore islands. In France, Portugal, Romania and the countries of Latin America, the cognates of North America designate a subcontinent of the Americas comprising Canada, the United States, Mexico, Greenland, Saint Pierre et Miquelon, Bermuda. North America has been referred to by other names. Spanish North America was referred to as Northern America, this was the first official name given to Mexico. Geographically the North American continent has many subregions; these include cultural and geographic regions. Economic regions included those formed by trade blocs, such as the North American Trade Agreement bloc and Central American Trade Agreement.
Linguistically and culturally, the continent could be divided into Latin America. Anglo-America includes most of Northern America and Caribbean islands with English-speaking populations; the southern North American continent is composed of two regions. These are the Caribbean; the north of the continent maintains recognized regions as well. In contrast to the common definition of "North America", which encompasses the whole continent, the term "North America" is sometimes used to refer only to Mexico, the United States, Greenland; the term Northern America refers to the northern-most countries and territories of North America: the United States, Bermuda, St. Pierre and Miquelon and Greenland. Although the term does not refer to a unifie
Mauna Kea is a dormant volcano on the island of Hawaii. Its peak is 4,207.3 m above sea level. Most of the mountain is under water, when measured from its oceanic base, Mauna Kea is the tallest mountain in the world measuring over 10,000 m. Mauna Kea is about a million years old, has thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous. Late volcanism has given it a much rougher appearance than its neighboring volcanoes due to construction of cinder cones, decentralization of its rift zones, glaciation on its peak, weathering by the prevailing trade winds. Mauna Kea last is now considered dormant; the peak is about 38 m higher than its more massive neighbor. In Hawaiian mythology, the peaks of the island of Hawaii are sacred. An ancient law allowed only high-ranking aliʻi to visit its peak. Ancient Hawaiians living on the slopes of Mauna Kea relied on its extensive forests for food, quarried the dense volcano-glacial basalts on its flanks for tool production.
When Europeans arrived in the late 18th century, settlers introduced cattle and game animals, many of which became feral and began to damage the mountain's ecological balance. Mauna Kea can be ecologically divided into three sections: an alpine climate at its summit, a Sophora chrysophylla–Myoporum sandwicense forest on its flanks, an Acacia koa–Metrosideros polymorpha forest, now cleared by the former sugar industry, at its base. In recent years, concern over the vulnerability of the native species has led to court cases that have forced the Hawai'i Department of Land and Natural Resources to eradicate all feral species on the mountain. With its high elevation, dry environment, stable airflow, Mauna Kea's summit is one of the best sites in the world for astronomical observation. Since the creation of an access road in 1964, thirteen telescopes funded by eleven countries have been constructed at the summit; the Mauna Kea Observatories are used for scientific research across the electromagnetic spectrum and comprise the largest such facility in the world.
Their construction on a landscape considered sacred by Native Hawaiians continues to be a topic of debate. Mauna Kea is one of five volcanoes that form the island of Hawaii, the largest and youngest island of the Hawaiian–Emperor seamount chain. Of these five hotspot volcanoes, Mauna Kea is the fourth oldest and fourth most active, it began as a preshield volcano driven by the Hawaii hotspot around one million years ago, became exceptionally active during its shield stage until 500,000 years ago. Mauna Kea entered its quieter post-shield stage 250,000 to 200,000 years ago, is dormant. Mauna Kea does not have a visible summit caldera, but contains a number of small cinder and pumice cones near its summit. A former summit caldera may have been filled and buried by summit eruption deposits. Mauna Kea is over 32,000 km3 in volume, so massive that it and its neighbor, Mauna Loa, depress the ocean crust beneath it by 6 km; the volcano continues to slip and flatten under its own weight at a rate of less than 0.2 mm per year.
Much of its mass lies east of its present summit. Mauna Kea stands 4,207.3 m above sea level, about 38 m higher than its neighbor Mauna Loa, is the highest point in the state of Hawaii. Measured from its base on the ocean floor, it rises over 10,000 m greater than the elevation of Mount Everest above sea level. Like all Hawaiian volcanoes, Mauna Kea has been created as the Pacific tectonic plate has moved over the Hawaiian hotspot in the Earth's underlying mantle; the Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has created the 6,000 km -long Hawaiian Ridge–Emperor seamount chain. The prevailing, though not settled, view is that the hotspot has been stationary within the planet's mantle for much, if not all of the Cenozoic Era. However, while Hawaiian volcanism is well understood and extensively studied, there remains no definite explanation of the mechanism that causes the hotspot effect. Lava flows from Mauna Kea overlapped in complex layers with those of its neighbors during its growth.
Most prominently, Mauna Kea is built upon older flows from Kohala to the northwest, intersects the base of Mauna Loa to the south. The original eruptive fissures in the flanks of Mauna Kea were buried by its post-shield volcanism. Hilo Ridge, a prominent underwater rift zone structure east of Mauna Kea, was once believed to be a part of the volcano; the shield-stage lavas that built the enormous main mass of the mountain are tholeiitic basalts, like those of Mauna Loa, created through the mixing of primary magma and subducted oceanic crust. They are covered by the oldest exposed rock strata on Mauna Kea, the post-shield alkali basalts of the Hāmākua Volcanics, which erupted between 250,000 and 70–65,000 years ago; the most recent volcanic flows are hawaiites and mugearites: they are the post-shield Laupāhoehoe Volcanics, erupted between 65,000 and 4,000 years ago. These changes in lava composition accompanied the slow reduction of the supply of magma to the summit, which led to weaker eruptions that gave way to isolated episodes associated with volcanic dormancy.
The Laupāhoehoe lavas are more viscous and contain more volatiles than the earlier tholeiitic basalts.
Aconcagua, with a summit elevation of 6,960.8 metres, is the highest mountain in both the Southern and Western Hemispheres. It is located in the Andes mountain range, in the Mendoza Province and lies 112 km northwest of its capital, the city of Mendoza, about five km from San Juan Province and 15 km from the international border with Chile; the mountain itself lies within Argentina east of Argentina's border with Chile. Its nearest higher neighbor is Tirich Mir in the Hindu Kush, 16,520 kilometres away, it is one of the Seven Summits. Aconcagua is bounded by the Valle de las Vacas to the north and east and the Valle de los Horcones Inferior to the west and south; the mountain and its surroundings are part of the Aconcagua Provincial Park. The mountain has a number of glaciers; the largest glacier is the Ventisquero Horcones Inferior at about 10 km long, which descends from the south face to about 3,600 m in altitude near the Confluencia camp. Two other large glacier systems are the Ventisquero de las Vacas Sur and Glaciar Este/Ventisquero Relinchos system at about five kilometres long.
The most well-known is Polish Glacier, as it is a common route of ascent. The origin of the name is contested; the mountain was created by the subduction of the Nazca Plate beneath the South American Plate. Aconcagua used to be an active stratovolcano and consisted of several volcanic complexes on the edge of a basin with a shallow sea. However, sometime in the Miocene, about 8 to 10 million years ago, the subduction angle started to decrease resulting in a stop of the melting and more horizontal stresses between the oceanic plate and the continent, causing the thrust faults that lifted Aconcagua up off its volcanic root; the rocks found on Aconcagua's flanks are all volcanic and consist of lavas and pyroclastics. The shallow marine basin had formed earlier before Aconcagua arose as a volcano. However, volcanism has been present in this region for as long as this basin was around and volcanic deposits interfinger with marine deposits throughout the sequence; the colorful greenish and grey deposits that can be seen in the Horcones Valley and south of Puente Del Inca, are carbonates, limestones and evaporates that filled this basin.
The red colored rocks are cinder deposits and conglomerates of volcanic origin. In mountaineering terms, Aconcagua is technically an easy mountain if approached from the north, via the normal route. Aconcagua is arguably the highest non-technical mountain in the world, since the northern route does not require ropes and pins. Although the effects of altitude are severe, the use of supplemental oxygen is not common. Altitude sickness will affect most climbers to some extent, depending on the degree of acclimatization. Although the normal climb is technically easy, multiple casualties occur every year on this mountain; this is due to the large numbers of climbers who make the attempt and because many climbers underestimate the objective risks of the elevation and of cold weather, the real challenge on this mountain. Given the weather conditions close to the summit, cold weather injuries are common; the routes to the peak from the south and south-west ridges are more demanding and the south face climb is considered quite difficult.
The Polish Glacier Traverse route known as the "Falso de los Polacos" route, crosses through the Vacas valley, ascends to the base of the Polish Glacier traverses across to the normal route for the final ascent to the summit. The third most popular route is by the Polish Glacier itself. Provincial Park rangers do not maintain records of successful summits but estimates suggest a summit rate of 30-40%. About 75% of climbers are foreigners and 25% are Argentinean. Among foreigners, the United States leads in number of climbers, followed by Germany and the UK. About 54% of climbers ascend the Normal Route, 43% up the Polish Glacier Route, the remaining 3% on other routes; the camp sites on the normal route are listed below. Puente del Inca, 2,740 metres: A small village on the main road, with facilities including a lodge. Confluencia, 3,380 metres: A camp site a few hours into the national park. Plaza de Mulas, 4,370 metres: Base camp, claimed to be the second largest in the world. There are several meal tents and internet access.
There is a lodge approx. 1 km from the main campsite across the glacier. At this camp, climbers are screened by a medical team to check if they are fit enough to continue the climb. Camp Canadá, 5,050 metres: A large ledge overlooking Plaza de Mulas. Camp Alaska, 5,200 metres: Called'change of slope' in Spanish, a small site as the slope from Plaza de Mulas to Nido de Cóndores lessens. Not used. Nido de Cóndores, 5,570 metres: A large plateau with beautiful views. There is a park ranger camped here. Camp Berlín, 5,940 metres: The classic high camp, offering reasonable wind protection. Camp Colera, 6,000 metres: A larger, while more exposed, camp situated directly at the north ridge near Camp Berlín, with growing popularity. In January 20
Mount Everest, known in Nepali as Sagarmatha and in Tibetan as Chomolungma, is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The international border between Nepal and China runs across its summit point; the current official elevation of 8,848 m, recognized by China and Nepal, was established by a 1955 Indian survey and subsequently confirmed by a Chinese survey in 1975. In 2005, China remeasured the rock height of the mountain, with a result of 8844.43 m. There followed an argument between China and Nepal as to whether the official height should be the rock height or the snow height. In 2010, an agreement was reached by both sides that the height of Everest is 8,848 m, Nepal recognizes China's claim that the rock height of Everest is 8,844 m. In 1865, Everest was given its official English name by the Royal Geographical Society, upon a recommendation by Andrew Waugh, the British Surveyor General of India; as there appeared to be several different local names, Waugh chose to name the mountain after his predecessor in the post, Sir George Everest, despite Everest's objections.
Mount Everest attracts many climbers, some of them experienced mountaineers. There are two main climbing routes, one approaching the summit from the southeast in Nepal and the other from the north in Tibet. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness and wind, as well as significant hazards from avalanches and the Khumbu Icefall; as of 2017, nearly 300 people have died on Everest. The first recorded efforts to reach Everest's summit were made by British mountaineers; as Nepal did not allow foreigners into the country at the time, the British made several attempts on the north ridge route from the Tibetan side. After the first reconnaissance expedition by the British in 1921 reached 7,000 m on the North Col, the 1922 expedition pushed the north ridge route up to 8,320 m, marking the first time a human had climbed above 8,000 m. Seven porters were killed in an avalanche on the descent from the North Col; the 1924 expedition resulted in one of the greatest mysteries on Everest to this day: George Mallory and Andrew Irvine made a final summit attempt on 8 June but never returned, sparking debate as to whether or not they were the first to reach the top.
They had been spotted high on the mountain that day but disappeared in the clouds, never to be seen again, until Mallory's body was found in 1999 at 8,155 m on the north face. Tenzing Norgay and Edmund Hillary made the first official ascent of Everest in 1953, using the southeast ridge route. Norgay had reached 8,595 m the previous year as a member of the 1952 Swiss expedition; the Chinese mountaineering team of Wang Fuzhou, Qu Yinhua made the first reported ascent of the peak from the north ridge on 25 May 1960. The history of this area dates back to 800 BCE, when the ancient Kirati had their Kirata Kingdom in the Himalayan mountains; the Mahalangur range of the Himalaya is known as Kirat area of eastern Nepal. In 1715, the Qing Empire of China surveyed the mountain while mapping its territory and depicted it as Mount Qomolangma no than 1719. In 1802, the British began the Great Trigonometric Survey of India to fix the locations and names of the world's highest mountains. Starting in southern India, the survey teams moved northward using giant theodolites, each weighing 500 kg and requiring 12 men to carry, to measure heights as as possible.
They reached the Himalayan foothills by the 1830s, but Nepal was unwilling to allow the British to enter the country due to suspicions of political aggression and possible annexation. Several requests by the surveyors to enter Nepal were turned down; the British were forced to continue their observations from Terai, a region south of Nepal, parallel to the Himalayas. Conditions in Terai were difficult because of malaria. Three survey officers died from malaria. Nonetheless, in 1847, the British continued the survey and began detailed observations of the Himalayan peaks from observation stations up to 240 km distant. Weather restricted work to the last three months of the year. In November 1847, Andrew Waugh, the British Surveyor General of India made several observations from the Sawajpore station at the east end of the Himalayas. Kangchenjunga was considered the highest peak in the world, with interest, he noted a peak beyond it, about 230 km away. John Armstrong, one of Waugh's subordinates saw the peak from a site farther west and called it peak "b".
Waugh would write that the observations indicated that peak "b" was higher than Kangchenjunga, but given the great distance of the observations, closer observations were required for verification. The following year, Waugh sent a survey official back to Terai to make closer observations of peak "b", but clouds thwarted his attempts. In 1849, Waugh dispatched James Nicolson to the area, who made two observations from Jirol, 190 km away. Nicolson took the largest theodolite and headed east, obtaining over 30 observations from five different locations, with the closest being 174 km from the peak. Nicolson retreated to Patna on the Ganges to perform the necessary calculations based on his observations, his raw data gave an average height of 9,200 m for peak "b", but this did not consider light refraction, which distorts heights. However, the number indica
China the People's Republic of China, is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering 9,600,000 square kilometers, it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, the special administrative regions of Hong Kong and Macau. China emerged as one of the world's earliest civilizations, in the fertile basin of the Yellow River in the North China Plain. For millennia, China's political system was based on hereditary monarchies, or dynasties, beginning with the semi-legendary Xia dynasty in 21st century BCE. Since China has expanded, re-unified numerous times. In the 3rd century BCE, the Qin established the first Chinese empire; the succeeding Han dynasty, which ruled from 206 BC until 220 AD, 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 and Northern Song completed the Four Great Inventions. Tang culture spread in Asia, as the new Silk Route brought traders to as far as Mesopotamia and Horn of Africa. Dynastic rule ended in 1912 with the Xinhai Revolution; the Chinese Civil War resulted in a division of territory in 1949, when the Communist Party of China established the People's Republic of China, a unitary one-party sovereign state on Mainland China, while the Kuomintang-led government retreated to the island of Taiwan. The political status of Taiwan remains disputed. Since the introduction of economic reforms in 1978, China's economy has been one of the world's fastest-growing with annual growth rates above 6 percent. According to the World Bank, China's GDP grew from $150 billion in 1978 to $12.24 trillion by 2017. Since 2010, China has been the world's second-largest economy by nominal GDP and since 2014, the largest economy in the world by purchasing power parity.
China is the world's largest exporter and second-largest importer of goods. China is a recognized nuclear weapons state and has the world's largest standing army and second-largest defense budget; the PRC is a permanent member of the United Nations Security Council as it replaced the ROC in 1971, as well as an active global partner of ASEAN Plus mechanism. China is a leading member of numerous formal and informal multilateral organizations, including the Shanghai Cooperation Organization, WTO, APEC, BRICS, the BCIM, the G20. In recent times, scholars have argued that it will soon be a world superpower, rivaling the United States; the word "China" has been used in English since the 16th century. It is not a word used by the Chinese themselves, it has been traced through Portuguese and Persian back to the Sanskrit word Cīna, used in ancient India."China" appears in Richard Eden's 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. Barbosa's usage was derived from Persian Chīn, in turn derived from Sanskrit Cīna.
Cīna was first used including the Mahābhārata and the Laws of Manu. In 1655, Martino Martini suggested that the word China is derived from the name of the Qin dynasty. Although this derivation is still given in various sources, it is complicated by the fact that the Sanskrit word appears in pre-Qin literature; the word may have referred to a state such as Yelang. The meaning transferred to China as a whole; the origin of the Sanskrit word is still a matter of debate, according to the Oxford English Dictionary. The official name of the modern state is the "People's Republic of China"; the shorter form is "China" Zhōngguó, from zhōng and guó, a term which developed under the Western Zhou dynasty in reference to its royal demesne. It was applied to the area around Luoyi during the Eastern Zhou and to China's Central Plain before being used as an occasional synonym for the state under the Qing, it was used as a cultural concept to distinguish the Huaxia people from perceived "barbarians".

Archaeological evidence suggests that early hominids inhabited China between 2.24 million and 250,000 years ago. The hominid fossils of Peking Man, a Homo erectus who used fire, were discovered in a cave at Zhoukoudian near Beijing; the fossilized teeth of Homo sapiens have been discovered in Fuyan Cave in Hunan. Chinese proto-writing existed in Jiahu around 7000 BCE, Damaidi around 6000 BCE, Dadiwan from 5800–5400 BCE, Banpo dating from the 5th millennium BCE; some scholars have suggested. According to Chinese tradition, the first dynasty was the Xia, which emerged around 2100 BCE; the dynasty was considered mythical by historians until scientific excavations found early Bronze Age sites at Erlitou, Henan in 1959. It remains unclear whether these sites are the remains of the Xia dynasty or of another culture from the same period; the succeeding Shang dynasty is the earliest to be confirmed by contemporary records. The Shang ruled the plain of the Yellow River in eastern China from the 17th to the 11th century BCE.
