A bus is a road vehicle designed to carry many passengers. Buses can have a capacity as high as 300 passengers; the most common type of bus is the single-deck rigid bus, with larger loads carried by double-decker and articulated buses, smaller loads carried by midibuses and minibuses. Many types of buses, such as city transit buses and inter-city coaches, charge a fare. Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus do not charge a fare. In many jurisdictions, bus drivers require a special licence above and beyond a regular driver's licence. Buses may be used for scheduled bus transport, scheduled coach transport, school transport, private hire, or tourism. Horse-drawn buses were used from the 1820s, followed by steam buses in the 1830s, electric trolleybuses in 1882; the first internal combustion engine buses, or motor buses, were used in 1895. Interest has been growing in hybrid electric buses, fuel cell buses, electric buses, as well as ones powered by compressed natural gas or biodiesel.
As of the 2010s, bus manufacturing is globalised, with the same designs appearing around the world. Bus is a clipped form of the dative plural of omnis-e; the theoretical full name is in French voiture omnibus. The name originates from a mass-transport service started in 1823 by a French corn-mill owner named Stanislas Baudry in Richebourg, a suburb of Nantes. A by-product of his mill was hot water, thus next to it he established a spa business. In order to encourage customers he started a horse-drawn transport service from the city centre of Nantes to his establishment; the first vehicles stopped in front of the shop of a hatter named Omnés, which displayed a large sign inscribed "Omnes Omnibus", a pun on his Latin-sounding surname, omnes being the male and female nominative and accusative form of the Latin adjective omnis-e, combined with omnibus, the dative plural form meaning "for all", thus giving his shop the name "Omnés for all". His transport scheme was a huge success, although not as he had intended as most of his passengers did not visit his spa.
He turned the transport service into his principal lucrative business venture and closed the mill and spa. Nantes citizens soon gave the nickname "omnibus" to the vehicle. Having invented the successful concept Baudry moved to Paris and launched the first omnibus service there in April 1828. A similar service was introduced in London in 1829. Regular intercity bus services by steam-powered buses were pioneered in England in the 1830s by Walter Hancock and by associates of Sir Goldsworthy Gurney, among others, running reliable services over road conditions which were too hazardous for horse-drawn transportation; the first mechanically propelled omnibus appeared on the streets of London on 22 April 1833. Steam carriages were much less to overturn, they travelled faster than horse-drawn carriages, they were much cheaper to run, caused much less damage to the road surface due to their wide tyres. However, the heavy road tolls imposed by the turnpike trusts discouraged steam road vehicles and left the way clear for the horse bus companies, from 1861 onwards, harsh legislation eliminated mechanically propelled vehicles from the roads of Great Britain for 30 years, the Locomotive Act of that year imposing restrictive speed limits on "road locomotives" of 5 mph in towns and cities, 10 mph in the country.
In parallel to the development of the bus was the invention of the electric trolleybus fed through trolley poles by overhead wires. The Siemens brothers, William in England and Ernst Werner in Germany, collaborated on the development of the trolleybus concept. Sir William first proposed the idea in an article to the Journal of the Society of Arts in 1881 as an "...arrangement by which an ordinary omnibus...would have a suspender thrown at intervals from one side of the street to the other, two wires hanging from these suspenders. Although this experimental vehicle fulfilled all the technical criteria of a typical trolleybus, it was dismantled in the same year after the demonstration. Max Schiemann opened a passenger-carrying trolleybus in 1901 in Germany. Although this system operated only until 1904, Schiemann had developed what is now the standard trolleybus current collection system. In the early days, a few other methods of current collection were used. Leeds and Bradford became the first cities to put trolleybuses into service in Great Britain on 20 June 1911.
In Siegerland, two passenger bus lines ran but unprofitably, in 1895 using a six-passenger motor carriage developed from the 1893 Benz Viktoria. Another commercial bus line using the same model Benz omnibuses ran for a short time in 1898 in the rural area around Llandudno, Wales. Daimler produced one of the earliest motor-bus models in 1898, selling a double-decker bus to the Motor Traction Company, first used on the streets of London on 23 April 1898; the vehicle had a maximum speed of 18 km/h and accommodated up to 20 passengers, in an enclosed area below and on an open-air pl
American Samoa is an unincorporated territory of the United States located in the South Pacific Ocean, southeast of Samoa. Its location is centered around 14.2710° S, 170.1322° W. It is on the eastern border of the International Date Line. American Samoa consists of two coral atolls; the largest and most populous island is Tutuila, with the Manuʻa Islands, Rose Atoll, Swains Island included in the territory. All islands except for Swains Island are part of the Samoan Islands, located west of the Cook Islands, north of Tonga, some 300 miles south of Tokelau. To the west are the islands of the Wallis and Futuna group; as of April 2019 the population of American Samoa is 55,689 people. Most of them are "nationals but not citizens of the United States at birth". Most American Samoans can speak English and Samoan fluently. Samoan is the same language spoken in neighboring independent Samoa; the total land area is 199 square kilometers more than Washington, D. C. American Samoa is the southernmost territory of the United States and one of two U.
S. territories south of the Equator, along with the uninhabited Jarvis Island. Tuna products are the main exports, the main trading partner is the United States. American Samoa has been a member of the Pacific Community since 1983. During the 1918 flu pandemic, Governor John Martin Poyer quarantined the territory, because of his actions, American Samoa was one of the few places in the world where no flu-related deaths occurred. American Samoa is noted for having the highest rate of military enlistment of any U. S. state or territory. As of September 9, 2014, the local U. S. Army recruiting station in Pago Pago was ranked first in production out of the 885 Army recruiting stations and centers under the United States Army Recruiting Command, which includes the 50 states, the District of Columbia, Puerto Rico, the U. S. Virgin Islands, the Commonwealth of Northern Mariana Islands, the Federated States of Micronesia, the Marshall Islands, South Korea and Europe. Contact with Europeans began in the early 18th century.
Dutchman Jacob Roggeveen was the first known European to sight the Samoan Islands in 1722, calling them the "Baumann Islands" after one of his captains. This visit was followed by French explorer Louis-Antoine de Bougainville who named them the "Îles des Navigateurs" in 1768. British explorer James Cook recorded the island names in 1773, but never visited; the 1789 visit by La Perouse ended in an attack and resulted in the death of his second in command Capt. de Langle and several of his crew on a Tutuila water collection expedition. La Perouse named the island "Massacre Island", the bay near Aasu is still called "Massacre Bay". H. M. S. Pandora, under the command of Edwards, visited the island in 1791 during its search for the H. M. S. Bounty mutineers. Von Kotzebue visited in 1824. Mission work in the Samoas had begun in late 1830 when John Williams of the London Missionary Society arrived from the Cook Islands and Tahiti. By that time, the Samoans had gained a reputation for being savage and warlike, as violent altercations had occurred between natives and European visitors.
By the late nineteenth century, British and American vessels stopped at Samoa, as they valued Pago Pago Harbor as a refueling station for coal-fired shipping and whaling. The US Exploring Expedition visited in 1839. In March 1889, an Imperial German naval force entered a village on Samoa, in doing so destroyed some American property. Three American warships entered the Apia harbor and prepared to engage the three German warships found there. Before any shots were fired, a typhoon wrecked both German ships. A compulsory armistice was called because of the lack of any warships. At the turn of the twentieth century, international rivalries in the latter half of the century were settled by the 1899 Tripartite Convention in which Germany and the United States partitioned the Samoan Islands into two parts: The eastern island group became a territory of the United States and is today known as American Samoa. Forerunners to the Tripartite Convention of 1899 were the Washington Conference of 1887, the Treaty of Berlin of 1889 and the Anglo-German Agreement on Samoa of 1899.
The following year, the U. S. formally annexed its portion, a smaller group of eastern islands, one of which contains the noted harbor of Pago Pago. After the United States Navy took possession of eastern Samoa for the United States government, the existing coaling station at Pago Pago Bay was expanded into a full naval station, known as United States Naval Station Tutuila and commanded by a commandant; the Navy secured a Deed of Cession of Tutuila in 1900 and a Deed of Cession of Manuʻa in 1904 on behalf of the US government. The last sovereign of Manuʻa, the Tui Manuʻa Elisala, signed a Deed of Cession of Manuʻa following a series of U. S. naval trials, known as the "Trial of the Ipu", in Pago Pago, Taʻu, aboard a Pacific Squadron gunboat. The territory became known as the U. S. Naval Station Tutuila. On July 17, 1911, the US Naval Station Tutuila, composed of Tutuila, Aunu'u and Manu'a, was renamed American Samoa. In 1918, during the final stages of World War I, the flu pandemic had taken its toll, spreading from country to country.

The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
A driver's license is an official document plastic and the size of a credit card, permitting a specific individual to operate one or more types of motorized vehicles, such as a motorcycle, truck, or bus on a public road. In most international agreements the wording driving permit is used, for instance in the Vienna Convention on Road Traffic; the term driver's license is American English. In this article, the American terminology and spelling is used but in country specific sections, the local spelling variant is used; the laws relating to the licensing of drivers vary between jurisdictions. In some jurisdictions, a permit is issued after the recipient has passed a driving test, while in others, a person acquires their permit before beginning to drive. Different categories of permit exist for different types of motor vehicles large trucks and passenger vehicles; the difficulty of the driving test varies between jurisdictions, as do factors such as age and the required level of competence and practice.
Karl Benz, inventor of the modern automobile, received a written "Genehmigung" from the Grand Ducal authorities to operate his car on public roads in 1888 after residents complained about the noise and smell of his Motorwagen. Up until the start of the 20th century, European authorities issued similar permits to drive motor vehicles ad hoc, if at all. Mandatory licensing for drivers came into force on 1 January 1904 after the Motor Car Act 1903 received royal assent in the United Kingdom; every car owner had to register their vehicle with their local government authority and be able to prove registration of their vehicle on request. The minimum qualifying age was set at 17; the "driving licence" gave its holder'freedom of the road' with a maximum 20 mph speed limit. Compulsory testing was introduced with the passing of the Road Traffic Act. Prussia a state within the German Empire, introduced compulsory licensing on 29 September 1903. A test on mechanical aptitude had to be passed and the Dampfkesselüberwachungsverein was charged with conducting these tests.
In 1910, the German imperial government mandated the licensing of drivers on a national scale, establishing a system of tests and driver's education requirements, adopted in other countries. In 1909, the Convention with Respect to the International Circulation of Motor Vehicles recognized the need for qualifications and authorization for international driving. In 1929, the notion of an "International Driving Permit" was first mooted in an international convention. In 1949, the United Nations hosted another convention on road traffic that standardised rules on roads, rules, driver's permits and such, it specified that national "driving permits" should be pink and that an "International Driving Permit" for driving in a number of countries should have "grey" covers with white pages and that "The entire last page shall be drawn up in French". In 1968, the Convention on road traffic, ratified in 1977 and further updated in 2011, further modernised these agreements, its main regulations about drivers permits are in Annex 6 and Annex 7.
The active version of those is in force in each contracting party no than "29 March 2011". Article 41 of the convention describes key requirements: every driver of a motor vehicle must hold appropriate documentation. Other countries in Europe introduced driving tests during the twentieth century, the last of them being Belgium where, until as as 1977, it was possible to purchase and hold a permit without having to undergo a driving test; as automobile-related fatalities soared in North America, public outcry provoked legislators to begin studying the French and German statutes as models. On August 1, 1910, North America's first licensing law for motor vehicles went into effect in the U. S. state of New York, though it applied only to professional chauffeurs. In July 1913, the state of New Jersey became the first to require all drivers to pass a mandatory examination before receiving a license. Many countries, including Australia, New Zealand, the United Kingdom, the United States, have
The police are a constituted body of persons empowered by a state to enforce the law, to protect the lives and possessions of citizens, to prevent crime and civil disorder. Their powers include the legitimized use of force; the term is most associated with the police forces of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are defined as being separate from the military and other organizations involved in the defense of the state against foreign aggressors. Police forces are public sector services, funded through taxes. Law enforcement is only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order. In some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Police forces have become ubiquitous in modern societies.
Their role can be controversial, as some are involved to varying degrees in corruption, police brutality and the enforcement of authoritarian rule. A police force may be referred to as a police department, police service, gendarmerie, crime prevention, protective services, law enforcement agency, civil guard or civic guard. Members may be referred to as police officers, sheriffs, rangers, peace officers or civic/civil guards. Ireland differs from other English-speaking countries by using the Irish language terms Garda and Gardaí, for both the national police force and its members; the word police is the most universal and similar terms can be seen in many non-English speaking countries. Numerous slang terms exist for the police. Many slang terms for police officers are centuries old with lost etymology. One of the oldest, "cop", has lost its slang connotations and become a common colloquial term used both by the public and police officers to refer to their profession. First attested in English in the early 15th century in a range of senses encompassing' policy.
This is derived from πόλις, "city". Law enforcement in ancient China was carried out by "prefects" for thousands of years since it developed in both the Chu and Jin kingdoms of the Spring and Autumn period. In Jin, dozens of prefects were spread across the state, each having limited authority and employment period, they were appointed by local magistrates, who reported to higher authorities such as governors, who in turn were appointed by the emperor, they oversaw the civil administration of their "prefecture", or jurisdiction. Under each prefect were "subprefects" who helped collectively with law enforcement in the area; some prefects were responsible for handling investigations, much like modern police detectives. Prefects could be women; the concept of the "prefecture system" spread to other cultures such as Japan. In ancient Greece, publicly owned slaves were used by magistrates as police. In Athens, a group of 300 Scythian slaves was used to guard public meetings to keep order and for crowd control, assisted with dealing with criminals, handling prisoners, making arrests.
Other duties associated with modern policing, such as investigating crimes, were left to the citizens themselves. In the Roman empire, the army, rather than a dedicated police organization, provided security. Local watchmen were hired by cities to provide some extra security. Magistrates such as procurators fiscal and quaestors investigated crimes. There was no concept of public prosecution, so victims of crime or their families had to organize and manage the prosecution themselves. Under the reign of Augustus, when the capital had grown to one million inhabitants, 14 wards were created, their duties included capturing runaway slaves. The vigiles were supported by the Urban Cohorts who acted as a heavy-duty anti-riot force and the Praetorian Guard if necessary. In medieval Spain, Santa Hermandades, or "holy brotherhoods", peacekeeping associations of armed individuals, were a characteristic of municipal life in Castile; as medieval Spanish kings could not offer adequate protection, protective municipal leagues began to emerge in the twelfth century against banditry and other rural criminals, against the lawless nobility or to support one or another claimant to a crown.
These organizations became a long-standing fixture of Spain. The first recorded case of the formation of an hermandad occurred when the towns and the peasantry of the north united to police the pilgrim road to Santiago de Compostela in Galicia, protect the pilgrims against robber knights. Throughout the Middle Ages such alliances were formed by combinations of towns to protect the roads connecting them, were extended to political purposes. Among the most powerful was the league of North Castilian and Basque ports, the Hermandad de las marismas: Toledo and Villarreal; as one of their first acts after end of the War of the Castilian Succession in 1479, Ferdinand II of Aragon and Isabella I of Castile established the centrally-organized and efficient Holy
Guam is an unincorporated and organized territory of the United States in Micronesia in the western Pacific Ocean. It is the easternmost point and territory of the United States, along with the Northern Mariana Islands; the capital city of Guam is Hagåtña and the most populous city is Dededo. The inhabitants of Guam are called Guamanians, they are American citizens by birth. Indigenous Guamanians are the Chamorros, who are related to other Austronesian natives of Eastern Indonesia, the Philippines, Taiwan. Guam has been a member of the Pacific Community since 1983. In 2016, 162,742 people resided on Guam. Guam has a population density of 775 per square mile. In Oceania, it is the largest and southernmost of the Mariana Islands and the largest island in Micronesia. Among its municipalities, Mongmong-Toto-Maite has the highest population density at 3,691 per square mile, whereas Inarajan and Umatac have the lowest density at 119 per square mile; the highest point is Mount Lamlam at 1,332 feet above sea level.
Since the 1960s, the economy has been supported by two industries: tourism and the United States Armed Forces. The indigenous Chamorros settled the island 4,000 years ago. Portuguese explorer Ferdinand Magellan, while in the service of Spain, was the first European to visit the island, on March 6, 1521. Guam was colonized by Spain in 1668 with settlers, including Diego Luis de San Vitores, a Catholic Jesuit missionary. Between the 16th century and the 18th century, Guam was an important stopover for the Spanish Manila Galleons. During the Spanish–American War, the United States captured Guam on June 21, 1898. Under the Treaty of Paris, Spain ceded Guam to the United States on December 10, 1898. Guam is among the 17 non-self-governing territories listed by the United Nations. Before World War II, there were five American jurisdictions in the Pacific Ocean: Guam and Wake Island in Micronesia, American Samoa and Hawaii in Polynesia, the Philippines. On December 7, 1941, hours after the attack on Pearl Harbor, Guam was captured by the Japanese, who occupied the island for two and a half years.
During the occupation, Guamanians were subjected to beheadings, forced labor and torture. American forces recaptured the island on July 21, 1944. An unofficial but used territorial motto is "Where America's Day Begins", which refers to the island's close proximity to the international date line; the original inhabitants of Guam and the Northern Mariana Islands were the Chamorro people, who are believed to be descendants of Austronesian people originating from Southeast Asia as early as 2000 BC. The ancient Chamorro society had four classes: chamorri, matua and mana'chang; the matua were located in the coastal villages, which meant they had the best access to fishing grounds, whereas the mana'chang were located in the interior of the island. Matua and mana'chang communicated with each other, matua used achaot as intermediaries. There were "makåhna" or "kakahna", shamans with magical powers and "Suruhånu" or "Suruhåna" healers who use different kinds of plants and natural materials to make medicine.
Belief in spirits of ancient Chamorros called "Taotao mo'na" still persists as a remnant of pre-European culture. It is believed that "Suruhånu" or "Suruhåna" are the only ones who can safely harvest plants and other natural materials from their homes or "hålomtåno" without incurring the wrath of the "Taotao mo'na", their society was organized along matrilineal clans. Latte stones are stone pillars; the latte-stone was used as a foundation. Latte stones consist of a base shaped from limestone called the haligi and with a capstone, or tåsa, made either from a large brain coral or limestone, placed on top. A possible source for these stones, the Rota Latte Stone Quarry, was discovered in 1925 on Rota; the first European to travel to Guam was Portuguese navigator Ferdinand Magellan, sailing for the King of Spain, when he sighted the island on March 6, 1521, during his fleet's circumnavigation of the globe. When Magellan arrived on Guam, he was greeted by hundreds of small outrigger canoes that appeared to be flying over the water, due to their considerable speed.
These outrigger canoes were called Proas, resulted in Magellan naming Guam Islas de las Velas Latinas. Antonio Pigafetta said that the name was "Island of Sails", but he writes that the inhabitants "entered the ships and stole whatever they could lay their hands on", including "the small boat, fastened to the poop of the flagship." "Those people are poor, but ingenious and thievish, on account of which we called those three islands Islas de los Ladrones." Despite Magellan's visit, Guam was not claimed by Spain until January 26, 1565, by General Miguel López de Legazpi. From 1565 to 1815, Guam and the Northern Mariana Islands, the only Spanish outposts in the Pacific Ocean east of the Philippines, were an important resting stop for the Manila galleons, a fleet that covered the Pacific trade route between Acapulco and Manila. To protect these Pacific fleets, Spain built several defensive structures that still stand today, such as Fort Nuestra Señora de la Soledad in Umatac. Guam is the biggest single segment of Micronesia, the largest islands between the island of Kyushu, New Guinea, the Philippines, the Hawaiian Islands.
Spanish colonization commenced on June 15, 1
Australia the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area; the neighbouring countries are Papua New Guinea and East Timor to the north. The population of 25 million is urbanised and concentrated on the eastern seaboard. Australia's capital is Canberra, its largest city is Sydney; the country's other major metropolitan areas are Melbourne, Brisbane and Adelaide. Australia was inhabited by indigenous Australians for about 60,000 years before the first British settlement in the late 18th century, it is documented. After the European exploration of the continent by Dutch explorers in 1606, who named it New Holland, Australia's eastern half was claimed by Great Britain in 1770 and settled through penal transportation to the colony of New South Wales from 26 January 1788, a date which became Australia's national day; the population grew in subsequent decades, by the 1850s most of the continent had been explored and an additional five self-governing crown colonies established.
On 1 January 1901, the six colonies federated. Australia has since maintained a stable liberal democratic political system that functions as a federal parliamentary constitutional monarchy, comprising six states and ten territories. Being the oldest and driest inhabited continent, with the least fertile soils, Australia has a landmass of 7,617,930 square kilometres. A megadiverse country, its size gives it a wide variety of landscapes, with deserts in the centre, tropical rainforests in the north-east and mountain ranges in the south-east. A gold rush began in Australia in the early 1850s, its population density, 2.8 inhabitants per square kilometre, remains among the lowest in the world. Australia generates its income from various sources including mining-related exports, telecommunications and manufacturing. Indigenous Australian rock art is the oldest and richest in the world, dating as far back as 60,000 years and spread across hundreds of thousands of sites. Australia is a developed country, with the world's 14th-largest economy.
It has a high-income economy, with the world's tenth-highest per capita income. It is a regional power, has the world's 13th-highest military expenditure. Australia has the world's ninth-largest immigrant population, with immigrants accounting for 26% of the population. Having the third-highest human development index and the eighth-highest ranked democracy globally, the country ranks in quality of life, education, economic freedom, civil liberties and political rights, with all its major cities faring well in global comparative livability surveys. Australia is a member of the United Nations, G20, Commonwealth of Nations, ANZUS, Organisation for Economic Co-operation and Development, World Trade Organization, Asia-Pacific Economic Cooperation, Pacific Islands Forum and the ASEAN Plus Six mechanism; the name Australia is derived from the Latin Terra Australis, a name used for a hypothetical continent in the Southern Hemisphere since ancient times. When Europeans first began visiting and mapping Australia in the 17th century, the name Terra Australis was applied to the new territories.
Until the early 19th century, Australia was best known as "New Holland", a name first applied by the Dutch explorer Abel Tasman in 1644 and subsequently anglicised. Terra Australis still saw occasional usage, such as in scientific texts; the name Australia was popularised by the explorer Matthew Flinders, who said it was "more agreeable to the ear, an assimilation to the names of the other great portions of the earth". The first time that Australia appears to have been used was in April 1817, when Governor Lachlan Macquarie acknowledged the receipt of Flinders' charts of Australia from Lord Bathurst. In December 1817, Macquarie recommended to the Colonial Office. In 1824, the Admiralty agreed that the continent should be known by that name; the first official published use of the new name came with the publication in 1830 of The Australia Directory by the Hydrographic Office. Colloquial names for Australia include "Oz" and "the Land Down Under". Other epithets include "the Great Southern Land", "the Lucky Country", "the Sunburnt Country", "the Wide Brown Land".
The latter two both derive from Dorothea Mackellar's 1908 poem "My Country". Human habitation of the Australian continent is estimated to have begun around 65,000 to 70,000 years ago, with the migration of people by land bridges and short sea-crossings from what is now Southeast Asia; these first inhabitants were the ancestors of modern Indigenous Australians. Aboriginal Australian culture is one of the oldest continual civilisations on earth. At the time of first European contact, most Indigenous Australians were hunter-gatherers with complex economies and societies. Recent archaeological finds suggest. Indigenous Australians have an oral culture with spiritual values based on reverence for the land and a belief in the Dreamtime; the Torres Strait Islanders, ethnically Melanesian, obtained their livelihood from seasonal horticulture and the resources of their reefs and seas. The northern coasts and waters of Australia were visited s
