Etymology

The Americas are generally accepted as having been named after the Italian Italy (pronounced /ˈɪtəli/ ; Italian: Italia [iˈtaːlja]), officially the Italian Republic (Italian: Repubblica italiana), is a country located partly on the European Continent and partly on the Italian Peninsula in Southern Europe and on the two largest islands in the Mediterranean Sea, Sicily and Sardinia. Italy shares its northern, Alpine explorer Amerigo Vespucci Amerigo Vespucci was an Italian explorer, navigator and cartographer. The continents of North America and South America are generally believed to have derived their name from the feminized Latin version of his first name by the German cartographers Martin Waldseemüller Martin Waldseemüller was a German cartographer. He and Matthias Ringmann are credited with the first recorded usage of the word America, on the 1507 map Universalis Cosmographia in honor of the Florentine explorer Amerigo Vespucci and Matthias Ringmann Matthias Ringmann was a German cartographer and humanist poet. He is credited with naming America on the map of his friend Martin Waldseemüller. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies East Indies was a term used in from 1600 onwards for what is now known as Southeast Asia, and predominantly for the islands of Maritime Southeast Asia. The term is sometimes used to refer to all of Southeast Asia that came under Indian influence. It was contrasted with the West Indies, but a different landmass previously 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 (from Americus the discoverer ... as if it were the land of Americus, thus America).^[5]

For Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespucci's name (Americus Vespucius), but in its feminine form "America", following the examples of "Europa" and "Asia".

Later, when other mapmakers added North America, they extended the original name to it as well: in 1538, Gerard Mercator Gerardus Mercator was a Flemish cartographer. He was born in Rupelmonde in the County of Flanders. He is remembered for the Mercator projection world map, which is named after him. This proved very useful to many later explorers used the name America to all of the Western Hemisphere on his world map.^[6]

Some argue that the convention is to use the surname for naming discoveries except in the case of royalty and so a derivation from "Amerigo Vespucci" could be problematic.^[7] Ricardo Palma (1949) proposed a derivation from the "Amerrique" mountains of Central America—Vespucci was the first to discover South America and the Amerrique mountains of Central America, which connected his discoveries to those of Christopher Columbus Christopher Columbus was an Italian navigator, colonizer, and explorer whose voyages across the Atlantic Ocean led to general European awareness of the American continents in the Western Hemisphere. With his four voyages of exploration and several attempts at establishing a settlement on the island of Hispaniola, all funded by Isabella I of.

Alfred E. Hudd proposed a theory in 1908 that the continents are named after a Welsh merchant named Richard Amerike Richard Amerike (c. 1445–1503) was a wealthy English born merchant, royal customs officer and sheriff of Welsh descent. He was the principal owner of John Cabot's ship Matthew during his voyage of exploration to North America in 1497. It has been speculated that "America" is derived from his name, owing to his sponsorship of the from Bristol, who is believed to have financed John Cabot Giovanni Caboto was an Italian navigator and explorer whose 1497 discovery of North America is commonly held to be the second European voyage to the continent since Christopher Columbus a few years earlier. The official position of the Canadian and United Kingdom governments is that he landed on the island of Newfoundland's voyage of discovery from England to Newfoundland in 1497. A minutely explored belief that has been advanced is that America was named for a Spanish sailor bearing the ancient Visigothic The Visigoths were one of two main branches of the Goths, an East Germanic tribe; the Ostrogoths being the other. Together these tribes were among the barbarians who disturbed the late Roman Empire during the Migration Period. The romanized Visigoths first emerged as a distinct people during the fourth century, initially in the Balkans, where they name of 'Amairick'. Another is that the name is rooted in a Native American The indigenous peoples of the Americas are the pre-Columbian inhabitants of North, Central, and South America, their descendants, and many ethnic groups who identify with those peoples. They are often also referred to as Native Americans, Aboriginals, First Nations , Amerigine[dubious – discuss], and by Christopher Columbus' geographical and language.^[6]

History

Paleohistory

North America is the source of much of what humanity knows about geologic time The geologic time scale provides a system of chronologic measurement relating stratigraphy to time that is used by geologists, paleontologists and other earth scientists to describe the timing and relationships between events that have occurred during the history of the Earth. The table of geologic time spans presented here agrees with the dates periods.^[8] The geographic area that would later become the United States has been the source of more varieties of dinosaurs Dinosaurs are a diverse group of reptiles. They were the dominant terrestrial vertebrates for over 160 million years, from the late Triassic period until the end of the Cretaceous period (about 65 million years ago), when the Cretaceous–Tertiary extinction event caused the extinction of most dinosaur species, except for some birds. The fossil than any other modern country.^[8] According to paleontologist Paleontology [note 1] is the study of prehistoric life, including organisms' evolution and interactions with each other and their environments (their paleoecology). As a "historical science" it tries to explain causes rather than conduct experiments to observe effects. Paleontological observations have been documented as far back as the 5 Peter Dodson, this is primarily due to stratigraphy, climate and geography, human resources, and history.^[8] Much of the Mesozoic Era The Mesozoic Era is a period from about 250 million years ago to about 67 million years ago. It is called the Age of Dinosaurs because most dinosaurs developed, and went extinct, during that time. The Chicxulub impact and other events ended the era when a majority of species on earth went extinct is represented by exposed outcrops in the many arid regions of the continent.^[8] The most significant Late The Late Jurassic epoch of the Jurassic Period is the unit of geologic time from 161.2 ± 4.0 to 145.5 ± 4.0 million years ago, which is preserved in Upper Jurassic strata. In European lithostratigraphy, the name Malm indicates rocks of Late Jurassic age. In the past this name was also used to indicate the unit of geological time, but this usage Jurassic The Jurassic is a geologic period and system that extends from about 199.6± 0.6 Ma to 145.5± 4 Ma, that is, from the end of the Triassic to the beginning of the Cretaceous. The Jurassic constitutes the middle period of the Mesozoic Era, also known as the "Age of Reptiles". The start of the period is marked by the major Triassic– dinosaur-bearing fossil deposit in North America is the Morrison Formation The Morrison Formation is a distinctive sequence of Late Jurassic sedimentary rock that is found in the western United States, which has been the most fertile source of dinosaur fossils in North America. It is composed of mudstone, sandstone, siltstone and limestone and is light grey, greenish gray, or red. Most of the fossils occur in the green of the western United States.^[9]

Prehistory

Scientists have several theories as to the origins There have been several models of migration to the New World proposed by various academic communities. The question of how, when and why humans (Paleo-Indians) first entered the Americas is of intense interest to archaeologists and anthropologists, and has been a subject of heated debate for centuries. Current understanding of human migration into of the early human population of North America The Lithic peoples or Paleo-Indians are the earliest known humans of the Americas. The period's name derives from the appearance of "lithic flaked" stone tools. The indigenous peoples of North America The indigenous peoples of the Americas are the pre-Columbian inhabitants of North, Central, and South America, their descendants, and many ethnic groups who identify with those peoples. They are often also referred to as Native Americans, Aboriginals, First Nations , Amerigine[dubious – discuss], and by Christopher Columbus' geographical and themselves have many creation myths A creation myth or creation story is a symbolic narrative of a culture, tradition or people that describes their earliest beginnings, how the world they know began and how they first came into it. They are stories expressing, usually through metaphor and imagery, how the world came to be and what humanity’s place and role is in it. Creation, by which they assert that they have been present on the land since its creation.

Before contact with Europeans The pre-Columbian era incorporates all period subdivisions in the history and prehistory of the Americas before the appearance of significant European influences on the American continents, spanning the time of the original settlement in the Upper Paleolithic period to European colonization during the Early Modern period, the natives of North America were divided into many different polities A body politic refers to the people of a nation, state or country considered collectively as a body of organized citizens, from small bands A band society is the simplest form of human society. A band generally consists of a small kin group, no larger than an extended family or clan; it has been defined as consisting of no more than 30 to 50 individuals of a few families to large empires The term empire derives from the Latin imperium . Politically, an empire is a geographically extensive group of states and peoples (ethnic groups) united and ruled either by a monarch (emperor, empress) or an oligarchy. Geopolitically, the term empire has denoted very different, territorially-extreme states — at the strong end, the extensive. They lived in several "culture areas Ethnographers commonly classify indigenous peoples in the United States and Canada into ten geographical regions with shared cultural traits . The following list groups peoples by their region of origin, followed by the current location. See the individual article on each tribe or First Nation for a history of their movements. See the List of", which roughly correspond to geographic and biological zones North America is the third largest continent, or a portion of the second largest if North and South America are combined into the Americas and Africa, Europe and Asia are considered to be part of one supercontinent called Afro-Eurasia. With an estimated population of 460 million and an area of 24,346,000 km² , the northernmost of the two and give a good indication of the main lifeway Types of societies are categories of social groups that differ according to subsistence strategies; the way that humans use technology to provide needs for themselves. Although humans have established many types of societies throughout history, anthropologists tend to classify different societies according to the degree to which different groups or occupation of the people who lived there (e.g. the Bison hunters of the Great Plains, or the farmers of Mesoamerica). Native groups can also be classified by their language family (e.g. Athapascan or Uto-Aztecan). It is important to note that peoples with similar languages did not always share the same material culture, nor were they always allies.

Scientists believe that the Inuit people of the high Arctic came to North America much later than other native groups, as evidenced by the disappearance of Dorset culture artifacts from the archaeological record, and their replacement by the Thule people.

During the thousands of years of native inhabitation on the continent, cultures changed and shifted. Archaeologists often name different cultural groups they discover after the site where they were first found. One of the oldest cultures yet found is the Clovis culture of modern New Mexico. A more recent example is the group of related cultures called the Mound builders (e.g. the Fort Walton Culture), found in the Mississippi river valley. They flourished from 300 BC to the 150s AD.

The more southern cultural groups of North America were responsible for the domestication of many common crops now used around the world, such as tomatoes and squash. Perhaps most importantly they domesticated one of the world's major staples, maize (corn).

History

As a result of the development of agriculture in the south, many important cultural advances were made there. For example, the Maya civilization developed a writing system, built huge pyramids and temples, had a complex calendar, and developed the concept of zero around 400 CE, a few hundred years after the Mesopotamians.^[10] The Mayan culture was still present when the Spanish arrived in Central America, but political dominance in the area had shifted to the Aztec Empire further north.

Upon the arrival of the Europeans in the "New World", Native American population declined substantially, primarily due to the introduction of European diseases to which the Native Americans lacked immunity.^[11] Native peoples found their culture changed drastically. As such, their affiliation with political and cultural groups changed as well, several linguistic groups went extinct, and others changed quite quickly. The names and cultures that Europeans recorded for the natives were not necessarily the same as the ones they had used a few generations before, or the ones in use today.
