Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write') is the——study of the "lands," features, "inhabitants," and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth. And its human and natural complexities—not merely where objects are. But also how they have changed and "come to be." While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."
Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (c. 276 BC – c. 195/194 BC). The first recorded use of the word γεωγραφία was as the title of a book by, Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." However, the concepts of geography (such as cartography) date back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to the 9th century BCE in ancient Babylon. The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups. And cross-pollinated by trade between these groups. The core concepts of geography consistent between all approaches are a focus on space, place, time, and scale.
Today, geography is an extremely broad discipline with multiple approaches and modalities. There have been multiple attempts to organize the discipline, including the four traditions of geography, and into branches. Techniques employed can generally be broken down into quantitative and qualitative approaches, with many studies taking mixed-methods approaches. Common techniques include cartography, remote sensing, interviews, and surveying. (Full article...)

Black Moshannon State Park is a 3,480-acre (1,410 ha) Pennsylvania state park in Rush Township, Centre County, Pennsylvania, United States. It surrounds Black Moshannon Lake, formed by a dam on Black Moshannon Creek, which has given its name to the lake and park. The park is just west of the Allegheny Front, 9 miles (14 km) east of Philipsburg on Pennsylvania Route 504, and is largely surrounded by Moshannon State Forest. A bog in the park provides a habitat for diverse wildlife not common in other areas of the state, such as carnivorous plants, orchids, and species normally found farther north. As home to the "largest reconstituted bog in Pennsylvania", it was chosen by the Pennsylvania Department of Conservation and Natural Resources for its "25 Must-see Pennsylvania State Parks" list.
Humans have long used the Black Moshannon area for recreational, industrial, and subsistence purposes. The Seneca tribe used it as hunting and fishing grounds. European settlers cleared some land for farming, then clear-cut the vast stands of old-growth white pine and eastern hemlock. Black Moshannon State Park rose from the ashes of a depleted forest which had been largely destroyed by wildfire in the years following the lumber era. The forests were rehabilitated by the Civilian Conservation Corps during the Great Depression in the 1930s. Many of the buildings built by the Civilian Conservation Corps stand in the park today and are protected on the list of National Register of Historic Places in three historic districts.

Ireland is an island in Northern Europe in the north Atlantic Ocean. The island, of up to around 480 km (300 mi) north-south, and 275 km (171 mi) east-west, lies near the western edge of the European continental shelf, part of the Eurasian Plate. Its main geographical features include low central plains surrounded by coastal mountains. The highest peak is Carrauntoohil (Irish: Corrán Tuathail), which is 1,039 metres (3,409 ft) above sea level. The western coastline is rugged, with many islands, peninsulas, headlands and bays, while the southern and northern coasts feature a smaller number of substantial sea inlets, such as Lough Foyle and Cork Harbour; no part of the land is more than around 110 km (68 mi) from the sea. It was administratively divided into 32 counties, gathered in 4 provinces, though current arrangements, especially in Northern Ireland, differ from this model. The island is almost bisected by the River Shannon, which at 360.5 km (224 mi) with a 102.1 km (63 mi) estuary is the longest river in Ireland and flows south from County Cavan in the province of Ulster to form the boundary between Connacht and Leinster, and later Munster, and meet the Atlantic just south and west of Limerick. There are a number of sizeable lakes along Ireland's rivers, of which Lough Neagh is the largest.
Politically, the island consists of the Republic of Ireland, with jurisdiction over about five-sixths of the island, and Northern Ireland, a constituent part of the United Kingdom, with jurisdiction over the remaining sixth. Located west of the island of Great Britain, Ireland lies at approximately . It has a total area of 84,421 km (32,595 sq mi) and is separated from Great Britain by the Irish Sea, bounded to the north and south respectively by the North Channel and St George's Channel, and from mainland Europe by the Celtic Sea. Ireland forms the second largest landmass in the British Isles, together with Great Britain and the Isle of Man. (Full article...) -

The Schichau class consisted of 22 torpedo boats built for the Austro-Hungarian Navy between 1885 and 1891. The class was one of the first torpedo boat classes built for the Austro-Hungarian Navy, and they were initially powered by steam from a single locomotive boiler and were armed with two 37 mm (1.5 in) Hotchkiss guns and two 356 mm (14 in) torpedo tubes. The entire class was reconstructed between 1900 and 1910, when they received two Yarrow boilers and a second funnel.
Ten of the class were converted into minesweepers between 1911 and 1913. One boat was discarded in 1911, with the rest seeing active service as part of local defence forces for the Adriatic naval bases during World War I, with one being lost in the early days of the war. The remaining ten torpedo boats were also converted to minesweepers in 1917, although five still carried torpedoes. After the war, sixteen of the boats were allocated to Italy and four were allocated to the navy of the newly created Kingdom of the Serbs, Croats and Slovenes (later Yugoslavia). Two were commissioned while the other two were used for spare parts. Except for one of the Yugoslav boats which was retained as a training vessel, all of the boats had been discarded by 1929. After capture during the April 1941 Axis invasion of Yugoslavia in World War II, the remaining boat saw service with the Italians and then the Germans. She was lost while in German hands sometime after September 1943. (Full article...) -

Mount Melbourne is a 2,733-metre-high (8,967 ft) ice-covered stratovolcano in Victoria Land, Antarctica, between Wood Bay and Terra Nova Bay. It is an elongated mountain with a summit caldera filled with ice with numerous parasitic vents; a volcanic field surrounds the edifice. Mount Melbourne has a volume of about 180 cubic kilometres (43 cu mi) and consists of tephra deposits and lava flows; tephra deposits are also found encased within ice and have been used to date the last eruption of Mount Melbourne to 1892 ± 30 years. The volcano is fumarolically active.
The volcano is part of the McMurdo Volcanic Group, and together with The Pleiades, Mount Overlord, Mount Rittmann and the Malta Plateau forms a subprovince, the Melbourne volcanic province. The volcanism is related both to the West Antarctic Rift and to local tectonic structures such as faults and grabens. Mount Melbourne has mainly erupted trachyandesite and trachyte, which formed within a magma chamber; basaltic rocks are less common. (Full article...) -

Saguaro National Park is a United States national park in Pima County, southeastern Arizona. The 92,000-acre (37,000 ha) park consists of two separate areas—the Tucson Mountain District (TMD), about 10 miles (16 km) west of Tucson, and the Rincon Mountain District (RMD), about 10 miles (16 km) east of the city. Both districts preserve Sonoran Desert landscapes, fauna, and flora, including the giant saguaro cactus.
The volcanic rocks on the surface of the Tucson Mountain District differ greatly from the surface rocks of the Rincon Mountain District; over the past 30 million years, crustal stretching displaced rocks from beneath the Tucson Mountains of the Tucson Mountain District to form the Rincon Mountains of the Rincon Mountain District. Uplifted, domed, and eroded, the Rincon Mountains are significantly higher and wetter than the Tucson Mountains. The Rincons, as one of the Madrean Sky Islands between the southern Rocky Mountains and the Sierra Madre Oriental in Mexico, support high biodiversity and are home to many plants and animals that do not live in the Tucson Mountain District.

Lethbridge (/ˈlɛθbrɪdʒ/ LETH-brij) is a city in the province of Alberta, Canada. With a population of 106,550 in the 2023 municipal census. Lethbridge became the fourth Alberta city to surpass 100,000 people. The nearby Canadian Rocky Mountains contribute to the city's warm summers, mild winters, and windy climate. Lethbridge lies southeast of Calgary on the Oldman River.
Lethbridge is the commercial, financial, transportation and industrial centre of southern Alberta. The city's economy developed from drift mining for coal in the late 19th century and agriculture in the early 20th century. Half of the workforce is employed in the health, education, retail and hospitality sectors, and the top five employers are government-based. The only university in Alberta south of Calgary is in Lethbridge, and two of the three colleges in southern Alberta have campuses in the city. Cultural venues in the city include performing art theatres, museums and sports centres. (Full article...) -
Image 72005 USDA aerial imagery of Powder House Island
Powder House Island (also known as Dynamite Island) is an artificial island on the lower Detroit River in southeast Michigan, directly adjacent to the Canada–United States border. It was constructed in the late 1880s by the Dunbar & Sullivan Company to store explosives during their dredging of the Livingstone Channel, with the purpose of circumventing an 1880 court order forbidding the company to store explosives on nearby Fox Island.
Powder House Island was the location of dynamite storage sheds, as well as a dynamite factory and several ice houses. During this time, it was the site of a series of accidents, including fires in 1895 and 1919 (which both burned the island "to the water's edge"). Twenty short tons (18,000 kg) of the island's dynamite exploded in 1906 after two men "had been shooting with a revolver" near it; while there were no deaths (and only minor injuries to the two men), windows were shattered 3 mi (4.8 km) away and the explosion was clearly audible from 85 mi (137 km) away.

Biscayne National Park is an American national park located south of Miami, Florida in Miami-Dade County. The park preserves Biscayne Bay and its offshore barrier reefs. Ninety-five percent of the park is water, and the shore of the bay is the location of an extensive mangrove forest. The park covers 172,971 acres (270.3 sq mi; 700.0 km) and includes Elliott Key, the park's largest island and northernmost of the true Florida Keys, formed from fossilized coral reef. The islands farther north in the park are transitional islands of coral and sand. The offshore portion of the park includes the northernmost region of the Florida Reef, one of the largest coral reefs in the world.
Biscayne National Park protects four distinct ecosystems: the shoreline mangrove swamp, the shallow waters of Biscayne Bay, the coral limestone keys and the offshore Florida Reef. The shoreline swamps of the mainland and island margins provide a nursery for larval and juvenile fish, molluscs and crustaceans. The bay waters harbor immature and adult fish, seagrass beds, sponges, soft corals, and manatees. The keys are covered with tropical vegetation including endangered cacti and palms, and their beaches provide nesting grounds for endangered sea turtles. Offshore reefs and waters harbor more than 200 species of fish, pelagic birds, whales and hard corals. Sixteen endangered species including Schaus' swallowtail butterflies, smalltooth sawfish, manatees, and green and hawksbill sea turtles may be observed in the park. Biscayne also has a small population of threatened American crocodiles and a few American alligators. (Full article...) -

The Song dynasty (/sʊŋ/) was an imperial dynasty of China that ruled from 960 to 1279. The dynasty was founded by Emperor Taizu of Song, who usurped the throne of the Later Zhou dynasty and went on to conquer the rest of the Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period. The Song often came into conflict with the contemporaneous Liao, Western Xia and Jin dynasties in northern China. After retreating to southern China following attacks by the Jin dynasty, the Song was eventually conquered by the Mongol-led Yuan dynasty.
The dynasty is divided into two periods: Northern Song and Southern Song. During the Northern Song (Chinese: 北宋; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now Eastern China. The Southern Song (Chinese: 南宋; 1127–1279) refers to the period after the Song lost control of its northern half to the Jurchen-led Jin dynasty in the Jin–Song Wars. At that time, the Song court retreated south of the Yangtze and established its capital at Lin'an (now Hangzhou). Although the Song dynasty had lost control of the traditional Chinese heartlands around the Yellow River, the Southern Song Empire contained a large population and productive agricultural land, sustaining a robust economy. In 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire, died in 1259 while besieging the mountain castle Diaoyucheng, Chongqing. His younger brother Kublai Khan was proclaimed the new Great Khan and in 1271 founded the Yuan dynasty. After two decades of sporadic warfare, Kublai Khan's armies conquered the Song dynasty in 1279 after defeating the Southern Song in the Battle of Yamen, and reunited China under the Yuan dynasty.

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.

The Tang dynasty (/tɑːŋ/, ※; Chinese: 唐朝), or the Tang Empire, was an imperial dynasty of China that ruled from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilization, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty.
The Li family founded the dynasty after taking advantage of a period of Sui decline and precipitating their final collapse, in turn inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant. The devastating An Lushan Rebellion (755–763) shook the nation and led to the decline of central authority in the dynasty's latter half. Like the previous Sui dynasty, the Tang maintained a civil-service system by recruiting scholar-officials through standardized examinations and recommendations to office. The rise of regional military governors known as jiedushi during the 9th century undermined this civil order. The dynasty and central government went into decline by the latter half of the 9th century; agrarian rebellions resulted in mass population loss and displacement, widespread poverty, and further government dysfunction that ultimately ended the dynasty in 907.

Tutupaca is a volcano in the region of Tacna in Peru. It is part of the Peruvian segment of the Central Volcanic Zone, one of several volcanic belts in the Andes. Tutupaca consists of three overlapping volcanoes formed by lava flows and lava domes made out of andesite and dacite, which grew on top of older volcanic rocks. The highest of these is usually reported to be 5,815 metres (19,078 ft) tall and was glaciated in the past.
Several volcanoes in Peru have been active in recent times, including Tutupaca. Their volcanism is caused by the subduction of the Nazca Plate beneath the South America Plate. One of these volcanoes collapsed in historical time, probably in 1802, generating a large debris avalanche with a volume likely exceeding 0.6–0.8 cubic kilometres (0.14–0.19 cu mi) and a pyroclastic flow. The associated eruption was among the largest in Peru for which there are historical records. The volcano became active about 700,000 years ago, and activity continued into the Holocene, but whether there were historical eruptions was initially unclear; some eruptions were instead attributed to the less eroded Yucamane volcano. The Peruvian government plans to monitor the volcano for future activity. Tutupaca features geothermal manifestations with fumaroles and hot springs. (Full article...) -

- Protectorate of the Western Regions (Tarim Basin)
The Han dynasty was an imperial dynasty of China (202 BC – 9 AD, 25–220 AD), established by Liu Bang and ruled by the House of Liu. The dynasty was preceded by the short-lived Qin dynasty (221–206 BC) and a warring interregnum known as the Chu–Han contention (206–202 BC), and it was succeeded by the Three Kingdoms period (220–280 AD). The dynasty was briefly interrupted by the Xin dynasty (9–23 AD) established by the usurping regent Wang Mang, and is thus separated into two periods—the Western Han (202 BC – 9 AD) and the Eastern Han (25–220 AD). Spanning over four centuries, the Han dynasty is considered a golden age in Chinese history, and had a permanent impact on Chinese identity in later periods. The majority ethnic group of modern China refer to themselves as the "Han people" or "Han Chinese". The spoken Sinitic language and written Chinese are referred to respectively as the "Han language" and "Han characters".
The emperor was at the pinnacle of Han society and culture. He presided over the Han government but shared power with both the nobility and the appointed ministers who came largely from the scholarly gentry class. The Han Empire was divided into areas directly controlled by the central government called commanderies, as well as a number of semi-autonomous kingdoms. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States. From the reign of Emperor Wu (r. 141–87 BC) onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in 1912. (Full article...) -

The Bull Run River is a 21.9-mile (35.2 km) tributary of the Sandy River in the U.S. state of Oregon. Beginning at the lower end of Bull Run Lake in the Cascade Range, it flows generally west through the Bull Run Watershed Management Unit (BRWMU), a restricted area meant to protect the river and its tributaries from contamination. The river, impounded by two artificial storage reservoirs as well as the lake, is the primary source of drinking water for the city of Portland, Oregon.
It is likely that Native Americans living along the Columbia River as early as 10,000 years ago visited the Bull Run watershed in search of food. Within the past few thousand years they created trails over the Cascade Range and around Mount Hood, near the upper part of the Bull Run watershed. By the mid-19th century, pioneers used these trails to cross the mountains from east to west to reach the fertile Willamette Valley. In the 1890s, the City of Portland, searching for sources of clean drinking water, chose the Bull Run River. Dam-building, road construction, and legal action to protect the watershed began shortly thereafter, and Bull Run water began to flow through a large pipe to the city in 1895. (Full article...) -

Harry R. Truman (October 1896 – May 18, 1980) was an American businessman, bootlegger, and prospector. He
lived near Mount St. Helens, an active volcano in the state of Washington, and was the owner and caretaker of Mount St. Helens Lodge at Spirit Lake near the base of the mountain. Truman came to fame as a folk hero in the months leading up to the volcano's 1980 eruption after refusing to leave his home despite evacuation orders. He was killed by a pyroclastic flow that overtook his lodge and buried the site under 150 ft (46 m) of volcanic debris.
After Truman's death, his family and friends reflected on his love for the mountain. In 1981, Art Carney portrayed Truman in the docudrama film St. Helens. He was commemorated in a book by his niece, and also in various pieces of music, including songs by Headgear, Billy Jonas, and Shawn Wright and the Brothers Band. (Full article...)

Image 3Map credit: Heinrich C. BerannYellowstone National Park is an American national park located mostly in Wyoming and extending into Montana and Idaho. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular landmarks. It has many types of ecosystems, but the subalpine forest is the most abundant. The park is part of the South Central Rockies forests ecoregion. In 1978, Yellowstone was named a World Heritage Site by UNESCO.
This picture is a stylized panoramic map of Yellowstone National Park as viewed from the northeast, created in 1991 by Austrian painter and cartographer Heinrich C. Berann for the National Park Service.

Image 14Map: Strebe, using GeocartThe Gall–Peters projection, named after James Gall and Arno Peters, is a specialization of a configurable equal-area map projection known as the cylindrical equal-area projection. It achieved considerable notoriety in the late 20th century as the centerpiece of a controversy surrounding the political implications of map design; Peters promoted it as a more faithful representation than the Mercator projection, which inflates the sizes of regions farther from the equator and thus makes the (mostly technologically underdeveloped) equatorial countries appear smaller and therefore, according to Peters, less significant.
-
Image 15Map: Strebe, using GeocartThe Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. Because it represents paths of constant course as straight lines, it long served as the standard map projection for nautical purposes. However, it distorts the size of objects as the latitude increases: thus areas in the mid-latitudes appear significantly larger than their actual size relative to those the equator, and those near the poles are even more exaggerated. Most modern atlases no longer use the Mercator projection for world maps or for areas distant from the equator, preferring other cylindrical projections, or forms of equal-area projection.
Robert Hues (1553 – 24 May 1632) was an English mathematician and geographer. He attended St. Mary Hall at Oxford, and graduated in 1578. Hues became interested in geography and mathematics, and studied navigation at a school set up by Walter Raleigh. During a trip to Newfoundland, he made observations which caused him to doubt the accepted published values for variations of the compass. Between 1586 and 1588, Hues travelled with Thomas Cavendish on a circumnavigation of the globe, performing astronomical observations and taking the latitudes of places they visited. Beginning in August 1591, Hues and Cavendish again set out on another circumnavigation of the globe. During the voyage, Hues made astronomical observations in the South Atlantic, and continued his observations of the variation of the compass at various latitudes and at the Equator. Cavendish died on the journey in 1592, and Hues returned to England the following year.
In 1594, Hues published his discoveries in the Latin work Tractatus de globis et eorum usu (Treatise on Globes and Their Use) which was written to explain the use of the terrestrial and celestial globes that had been made and published by Emery Molyneux in late 1592 or early 1593, and to encourage English sailors to use practical astronomical navigation. Hues' work subsequently went into at least 12 other printings in Dutch, English, French and Latin. (Full article...)More featured biographies

A map of the United States showing its 50 states, federal district and five inhabited territories. Alaska, Hawaii, and the territories are shown at different scales, and the Aleutian Islands and the uninhabited northwestern Hawaiian Islands are omitted from the map.
The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. Both the states and the United States as a whole are each sovereign jurisdictions. The Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government. Each state has its own constitution and government, and all states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state is represented by two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state. The federal district does not have representatives in the Senate, but has a non-voting delegate in the House, and it is also entitled to electors in the Electoral College. Congress can admit more states, but it cannot create a new state from territory of an existing state or merge two or more states into one without the consent of all states involved, and each new state is admitted on an equal footing with the existing states.

Image 3The Blue Marble, Apollo 17, December 1972
Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is somewhat humid and covered by vegetation, while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers and atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth has a liquid outer core that generates a magnetosphere capable of deflecting most of the destructive solar winds and cosmic radiation. (Full article...) -

London (/ˈlʌndən/ LUN-dən) is the capital and largest city of both England and the United Kingdom, with a population of around 8.8 million. The wider metropolitan area is the largest in Western Europe, with a population of 14.9 million. London stands on the River Thames in southeast England, at the head of a 50-mile (80 km) estuary down to the North Sea, and has been a major settlement for nearly 2,000 years. Its ancient core and financial centre, the City of London, was founded by the Romans as Londinium and has retained its medieval boundaries. The City of Westminster, to the west of the City of London, has been the centuries-long host of the national government and parliament. London grew rapidly in the 19th century, becoming the world's largest city at the time as it expanded and absorbed the surrounding county of Middlesex alongside parts of Surrey and Kent. In 1965, it was combined with parts of Essex and Hertfordshire to create the administrative area of Greater London, which is governed by 33 local authorities and the Greater London Authority.

Cartogram of the world's population in 2018; each square represents 500,000 people.
This is a list of countries and dependencies by population. It includes sovereign states, inhabited dependent territories and, in some cases, constituent countries of sovereign states, with inclusion within the list being primarily based on the ISO standard ISO 3166-1. For instance, the United Kingdom is considered a single entity, while the constituent countries of the Kingdom of the Netherlands are considered separately. In addition, this list includes certain states with limited recognition not found in ISO 3166-1. Also given in a percentage is each country's population compared with the world population, which the United Nations estimates at 8.12 billion as of 2024. (Full article...) -
