Norway the Kingdom of Norway, is a Nordic country in Northern Europe whose territory comprises the western and northernmost portion of the Scandinavian Peninsula. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the kingdom. Norway lays claim to a section of Antarctica known as Queen Maud Land. Norway has a total area of 385,207 square kilometres and a population of 5,312,300; the country shares a long eastern border with Sweden. Norway is bordered by Finland and Russia to the north-east, the Skagerrak strait to the south, with Denmark on the other side. Norway has an extensive coastline, facing the Barents Sea. Harald V of the House of Glücksburg is the current King of Norway. Erna Solberg has been prime minister since 2013. A unitary sovereign state with a constitutional monarchy, Norway divides state power between the parliament, the cabinet and the supreme court, as determined by the 1814 constitution; the kingdom was established in 872 as a merger of a large number of petty kingdoms and has existed continuously for 1,147 years.
From 1537 to 1814, Norway was a part of the Kingdom of Denmark-Norway, from 1814 to 1905, it was in a personal union with the Kingdom of Sweden. Norway was neutral during the First World War. Norway remained neutral until April 1940 when the country was invaded and occupied by Germany until the end of Second World War. Norway has both administrative and political subdivisions on two levels: counties and municipalities; the Sámi people have a certain amount of self-determination and influence over traditional territories through the Sámi Parliament and the Finnmark Act. Norway maintains close ties with both the United States. Norway is a founding member of the United Nations, NATO, the European Free Trade Association, the Council of Europe, the Antarctic Treaty, the Nordic Council. Norway maintains the Nordic welfare model with universal health care and a comprehensive social security system, its values are rooted in egalitarian ideals; the Norwegian state has large ownership positions in key industrial sectors, having extensive reserves of petroleum, natural gas, lumber and fresh water.
The petroleum industry accounts for around a quarter of the country's gross domestic product. On a per-capita basis, Norway is the world's largest producer of oil and natural gas outside of the Middle East; the country has the fourth-highest per capita income in the world on the World IMF lists. On the CIA's GDP per capita list which includes autonomous territories and regions, Norway ranks as number eleven, it has the world's largest sovereign wealth fund, with a value of US$1 trillion. Norway has had the highest Human Development Index ranking in the world since 2009, a position held between 2001 and 2006, it had the highest inequality-adjusted ranking until 2018 when Iceland moved to the top of the list. Norway ranked first on the World Happiness Report for 2017 and ranks first on the OECD Better Life Index, the Index of Public Integrity, the Democracy Index. Norway has one of the lowest crime rates in the world. Norway has two official names: Norge in Noreg in Nynorsk; the English name Norway comes from the Old English word Norþweg mentioned in 880, meaning "northern way" or "way leading to the north", how the Anglo-Saxons referred to the coastline of Atlantic Norway similar to scientific consensus about the origin of the Norwegian language name.
The Anglo-Saxons of Britain referred to the kingdom of Norway in 880 as Norðmanna land. There is some disagreement about whether the native name of Norway had the same etymology as the English form. According to the traditional dominant view, the first component was norðr, a cognate of English north, so the full name was Norðr vegr, "the way northwards", referring to the sailing route along the Norwegian coast, contrasting with suðrvegar "southern way" for, austrvegr "eastern way" for the Baltic. In the translation of Orosius for Alfred, the name is Norðweg, while in younger Old English sources the ð is gone. In the 10th century many Norsemen settled in Northern France, according to the sagas, in the area, called Normandy from norðmann, although not a Norwegian possession. In France normanni or northmanni referred to people of Sweden or Denmark; until around 1800 inhabitants of Western Norway where referred to as nordmenn while inhabitants of Eastern Norway where referred to as austmenn. According to another theory, the first component was a word nór, meaning "narrow" or "northern", referring to the inner-archipelago sailing route through the land.
The interpretation as "northern", as reflected in the English and Latin forms of the name, would have been due to folk etymology. This latter view originated with philologist Niels Halvorsen Trønnes in 1847; the form Nore is still used in placenames such as the village of Nore and lake Norefjorden in Buskerud county, still has the same meaning. Among other arguments in favour of the theor
In earth science, erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, transports it to another location. This natural process is caused by the dynamic activity of erosive agents, that is, ice, air, plants and humans. In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind erosion, zoogenic erosion, anthropogenic erosion; the particulate breakdown of rock or soil into clastic sediment is referred to as physical or mechanical erosion. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Natural rates of erosion are controlled by the action of geological weathering geomorphic drivers, such as rainfall; the rates at which such processes act control. Physical erosion proceeds fastest on steeply sloping surfaces, rates may be sensitive to some climatically-controlled properties including amounts of water supplied, wind speed, wave fetch, or atmospheric temperature.
Feedbacks are possible between rates of erosion and the amount of eroded material, carried by, for example, a river or glacier. Processes of erosion that produce sediment or solutes from a place contrast with those of deposition, which control the arrival and emplacement of material at a new location. While erosion is a natural process, human activities have increased by 10-40 times the rate at which erosion is occurring globally. At well-known agriculture sites such as the Appalachian Mountains, intensive farming practices have caused erosion up to 100x the speed of the natural rate of erosion in the region. Excessive erosion causes both "on-site" and "off-site" problems. On-site impacts include decreases in agricultural productivity and ecological collapse, both because of loss of the nutrient-rich upper soil layers. In some cases, the eventual end result is desertification. Off-site effects include sedimentation of waterways and eutrophication of water bodies, as well as sediment-related damage to roads and houses.
Water and wind erosion are the two primary causes of land degradation. Intensive agriculture, roads, anthropogenic climate change and urban sprawl are amongst the most significant human activities in regard to their effect on stimulating erosion. However, there are many prevention and remediation practices that can curtail or limit erosion of vulnerable soils. Rainfall, the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, gully erosion. Splash erosion is seen as the first and least severe stage in the soil erosion process, followed by sheet erosion rill erosion and gully erosion. In splash erosion, the impact of a falling raindrop creates a small crater in the soil, ejecting soil particles; the distance these soil particles travel can be as much as 0.6 m vertically and 1.5 m horizontally on level ground. If the soil is saturated, or if the rainfall rate is greater than the rate at which water can infiltrate into the soil, surface runoff occurs.
If the runoff has sufficient flow energy, it will transport loosened soil particles down the slope. Sheet erosion is the transport of loosened soil particles by overland flow. Rill erosion refers to the development of small, ephemeral concentrated flow paths which function as both sediment source and sediment delivery systems for erosion on hillslopes. Where water erosion rates on disturbed upland areas are greatest, rills are active. Flow depths in rills are of the order of a few centimetres or less and along-channel slopes may be quite steep; this means that rills exhibit hydraulic physics different from water flowing through the deeper, wider channels of streams and rivers. Gully erosion occurs when runoff water accumulates and flows in narrow channels during or after heavy rains or melting snow, removing soil to a considerable depth. Valley or stream erosion occurs with continued water flow along a linear feature; the erosion is both downward, deepening the valley, headward, extending the valley into the hillside, creating head cuts and steep banks.
In the earliest stage of stream erosion, the erosive activity is dominantly vertical, the valleys have a typical V cross-section and the stream gradient is steep. When some base level is reached, the erosive activity switches to lateral erosion, which widens the valley floor and creates a narrow floodplain; the stream gradient becomes nearly flat, lateral deposition of sediments becomes important as the stream meanders across the valley floor. In all stages of stream erosion, by far the most erosion occurs during times of flood when more and faster-moving water is available to carry a larger sediment load. In such processes, it is not the water alone
The Earth scientists, who study rivers and streams, define a pothole as a smooth, bowl-shaped or cylindrical hollow deeper than wide, found carved into the rocky bed of a watercourse. Other names used for riverine potholes are pot, giant's kettle, hollow, rock mill, churn hole, eddy mill, kolk. Although somewhat related to a pothole in origin, a plunge pool is the deep depression in a stream bed at the base of a waterfall. Potholes are sometimes referred to as swirlholes; this word was created to avoid confusion with an English term for a vertical or steeply inclined karstic shaft in limestone. However, given widespread usage of this term for a type of fluvial sculpted bedrock landform, pothole is preferred in usage to swirlhole; the term pothole is used to refer to other types of depressions and basins that differ in origin. For example, some authors refer to panholes found in the Colorado Plateau as potholes. Other terms used for panholes are gnamma, armchair hollows, weathering pans and solution pans or solution pits.
In another case, the term pothole is used to refer to a shallow depression less than 10-acre in area that occurs between dunes or on subdued morainic relief on a prairie, as in Minnesota and the Dakotas, contains an intermittent pond or marsh that serves as a nesting place for waterfowl. The consensus of geomorphologists and sedimentologists is that fluvial potholes are created by the grinding action of either a stone or stones or coarse sediment, whirled around and kept in motion by eddies within and force of the stream current in a given spot. Being a spectacular feature of bedrock river channels, they have been and still are studied extensively and considered as a key factor in bedrock channel development and morphology and important factor in the incision of bedrock channels
Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice, it is abundant on Earth's surface – in the polar regions and above the snow line – and, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It occurs as frost, icicles or ice spikes. Ice molecules can exhibit more different phases that depend on temperature and pressure; when water is cooled up to three different types of amorphous ice can form depending on the history of its pressure and temperature. When cooled correlated proton tunneling occurs below −253.15 °C giving rise to macroscopic quantum phenomena. All the ice on Earth's surface and in its atmosphere is of a hexagonal crystalline structure denoted as ice Ih with minute traces of cubic ice denoted as ice Ic.
The most common phase transition to ice Ih occurs when liquid water is cooled below 0 °C at standard atmospheric pressure. It may be deposited directly by water vapor, as happens in the formation of frost; the transition from ice to water is melting and from ice directly to water vapor is sublimation. Ice is used in a variety including cooling, winter sports and ice sculpture; as a occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral. It possesses a regular crystalline structure based on the molecule of water, which consists of a single oxygen atom covalently bonded to two hydrogen atoms, or H–O–H. However, many of the physical properties of water and ice are controlled by the formation of hydrogen bonds between adjacent oxygen and hydrogen atoms. An unusual property of ice frozen at atmospheric pressure is that the solid is 8.3% less dense than liquid water. The density of ice is 0.9167–0.9168 g/cm3 at 0 °C and standard atmospheric pressure, whereas water has a density of 0.9998–0.999863 g/cm3 at the same temperature and pressure.
Liquid water is densest 1.00 g/cm3, at 4 °C and becomes less dense as the water molecules begin to form the hexagonal crystals of ice as the freezing point is reached. This is due to hydrogen bonding dominating the intermolecular forces, which results in a packing of molecules less compact in the solid. Density of ice increases with decreasing temperature and has a value of 0.9340 g/cm3 at −180 °C. When water freezes, it increases in volume; the effect of expansion during freezing can be dramatic, ice expansion is a basic cause of freeze-thaw weathering of rock in nature and damage to building foundations and roadways from frost heaving. It is a common cause of the flooding of houses when water pipes burst due to the pressure of expanding water when it freezes; the result of this process is that ice floats on liquid water, an important feature in Earth's biosphere. It has been argued that without this property, natural bodies of water would freeze, in some cases permanently, from the bottom up, resulting in a loss of bottom-dependent animal and plant life in fresh and sea water.
Sufficiently thin ice sheets allow light to pass through while protecting the underside from short-term weather extremes such as wind chill. This creates a sheltered environment for algal colonies; when sea water freezes, the ice is riddled with brine-filled channels which sustain sympagic organisms such as bacteria, algae and annelids, which in turn provide food for animals such as krill and specialised fish like the bald notothen, fed upon in turn by larger animals such as emperor penguins and minke whales. When ice melts, it absorbs as much energy as it would take to heat an equivalent mass of water by 80 °C. During the melting process, the temperature remains constant at 0 °C. While melting, any energy added breaks the hydrogen bonds between ice molecules. Energy becomes available to increase the thermal energy only after enough hydrogen bonds are broken that the ice can be considered liquid water; the amount of energy consumed in breaking hydrogen bonds in the transition from ice to water is known as the heat of fusion.
As with water, ice absorbs light at the red end of the spectrum preferentially as the result of an overtone of an oxygen–hydrogen bond stretch. Compared with water, this absorption is shifted toward lower energies. Thus, ice appears blue, with a greener tint than liquid water. Since absorption is cumulative, the color effect intensifies with increasing thickness or if internal reflections cause the light to take a longer path through the ice. Other colors can appear in the presence of light absorbing impurities, where the impurity is dictating the color rather than the ice itself. For instance, icebergs containing impurities can appear grey or green. Ice may be any one of the 18 known solid crystalline phases of water, or in an amorphous solid state at various densities. Most liquids under increased pressure freeze at higher temperatures because the pressure helps to hold the molecules together. However, the strong hydrogen bonds in water make it different: For some pressures higher than 1 atm, water freezes at a temperature below
Rovaniemi is a city and municipality of Finland. It is the administrative capital and commercial centre of Lapland, it is situated about 6 kilometres south of the Arctic Circle and is between the hills of Ounasvaara and Korkalovaara, at the confluence of the river Kemijoki and its tributary, the Ounasjoki. The city and the surrounding Rovaniemen maalaiskunta were consolidated into a single entity on 1 January 2006; the new municipality has an area of 8,016.75 square kilometres, thus making it the largest city in the European Union by land. Rovaniemi has an approximate population of 63,000. Rovaniemi is a unilingual Finnish-speaking municipality and uncommonly for larger Finnish towns, it is known by its Finnish name and spelling in the Swedish language; the rova part in the name Rovaniemi has been considered to be of Saamic origin, as roavve in Saami denotes a forested ridge or hill or the site of an old forest fire. In Southern Saami dialects, rova means a heap of stones, a rock or a group of rocks in a stretch of rapids or a sauna stove.
The niemi part of the name means "cape". Names in the Samic languages include Inari Sami: Ruávinjargâ, Northern Sami: Roavenjárga and Roavvenjárga and Skolt Sami: Ruäˊvnjargg. Periodic clearance of new land for agriculture and the practise of slash-and-burn cultivation began around 750–530 BC. Artifacts found in the area suggest that an increasing number of travellers from Karelia in the east, Häme in the south and the Arctic Ocean coast in the north must have come there from 500 AD onwards; the Sami are considered to be Lapland's most indigenous existing population. It is first mentioned by name in official documents in 1453, existing as a set of small villages whose inhabitants earned their living in agriculture and animal husbandry—with fishing and hunting the most important offshoots; the exploitation of Lapland's natural resources in the 1800s boosted Rovaniemi's growth. Extensive logging sites and gold fever attracted thousands of people to Lapland; as the mining of natural resources was increased, Rovaniemi became the business centre of the province of Lapland.
During the Second World War, Finland signed the Moscow Armistice and found itself involved in the Lapland War with its former German ally. Retreating German forces utilised scorched earth tactics, though German General Lothar Rendulic ordered only the public buildings in Rovaniemi to be destroyed, on 13 October 1944 the German army received orders to destroy all the buildings in Rovaniemi, only excluding hospitals and houses where inhabitants were present. While the German rear guard was going about the destruction, an ammunition train in Rovaniemi station exploded and set fire to the wooden houses of the town; the German troops suffered many casualties from glass splinters. A Finnish commando unit claimed to have blown up the ammunition train and may well have been the primary cause of the town's ruin; the cause was unknown and assumed to be the deliberate intent of Rendulic. During these hostilities 90% of all the buildings in Rovaniemi were destroyed. There is a German cemetery 19 km from Rovaniemi where soldiers killed fighting in Lapland during the war are buried.
Because of the unspoiled nature of the area and numerous recreational opportunities, tourism is an important industry in Rovaniemi. The city has a number of hotels and restaurants located both in the centre and on the outskirts of the town, hosting over 481,000 visitors in 2013. Since Rovaniemi is the capital of the Province of Lapland, many government institutions have their offices there. About 10,000 of the inhabitants are students. Rovaniemi is home to not only the University of Lapland but the Lapland University of Applied Sciences, which comprises institutes of information and traditional technology, business and social care, culinary studies, rural studies and sports. Local newspapers include Uusi Rovaniemi and Lappilainen. Rovaniemi's most prominent landmarks include the Jätkänkynttilä bridge with its eternal flame over the Kemijoki river, the Arktikum House which rises out of the bank of the Ounasjoki river, the Rovaniemi Town Hall, the Lappia House which serves as a theatre, concert hall and congress centre, the library.
The last three mentioned. Rovaniemi is considered by Finns to be the official home town of Santa Claus, is home to the Santa Claus Village at the Arctic Circle and Santa Park, located 8 km north of the centre; the Arktikum is a comprehensive museum of Finland's and the world's Arctic regions. Directly across the river from the town is the Ounasvaara ski centre; the top of the Ounasvaara hill bears the site of some of the earliest known human settlements in the area. A phenomenon attracting numerous tourists is the Aurora Borealis or Northern Lights. In Finnish Lapland the number of auroral displays can be as high as 200 a year whereas in southern Finland the number is fewer than 20. VR Group, the Finnish state railway system, operates direct daytime and overnight passenger trains from Rovaniemi Station to Oulu, Tampere and Turku. Diesel-powered passenger trains operated north-east of Rovaniemi to Kemijärvi until March 2014, when electrification to Kemijärvi was completed. Rovaniemi Airport is located about 10 kilometres north of the Rovaniemi city centre.

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
Wisconsin is a U. S. state located in the Midwest and Great Lakes regions. It is bordered by Minnesota to the west, Iowa to the southwest, Illinois to the south, Lake Michigan to the east, Michigan to the northeast, Lake Superior to the north. Wisconsin is the 20th most populous; the state capital is Madison, its largest city is Milwaukee, located on the western shore of Lake Michigan. The state is divided into 72 counties. Wisconsin's geography is diverse, having been impacted by glaciers during the Ice Age with the exception of the Driftless Area; the Northern Highland and Western Upland along with a part of the Central Plain occupies the western part of the state, with lowlands stretching to the shore of Lake Michigan. Wisconsin is second to Michigan in the length of its Great Lakes coastline. During the 19th and early 20th centuries, a large number of European settlers entered the state, many of whom emigrated from Germany and Scandinavia. Like neighboring Minnesota, the state remains a center of German American and Scandinavian American culture.
Wisconsin is known as "America's Dairyland" because it is one of the nation's leading dairy producers famous for its cheese. Manufacturing, information technology, cranberries and tourism are major contributors to the state's economy; the word Wisconsin originates from the name given to the Wisconsin River by one of the Algonquian-speaking Native American groups living in the region at the time of European contact. French explorer Jacques Marquette was the first European to reach the Wisconsin River, arriving in 1673 and calling the river Meskousing in his journal. Subsequent French writers changed the spelling from Meskousing to Ouisconsin, over time this became the name for both the Wisconsin River and the surrounding lands. English speakers anglicized the spelling from Ouisconsin to Wisconsin when they began to arrive in large numbers during the early 19th century; the legislature of Wisconsin Territory made the current spelling official in 1845. The Algonquin word for Wisconsin and its original meaning have both grown obscure.
Interpretations vary. One leading theory holds that the name originated from the Miami word Meskonsing, meaning "it lies red", a reference to the setting of the Wisconsin River as it flows through the reddish sandstone of the Wisconsin Dells. Other theories include claims that the name originated from one of a variety of Ojibwa words meaning "red stone place", "where the waters gather", or "great rock". Wisconsin has been home to a wide variety of cultures over the past 14,000 years; the first people arrived around 10,000 BCE during the Wisconsin Glaciation. These early inhabitants, called Paleo-Indians, hunted now-extinct ice age animals such as the Boaz mastodon, a prehistoric mastodon skeleton unearthed along with spear points in southwest Wisconsin. After the ice age ended around 8000 BCE, people in the subsequent Archaic period lived by hunting and gathering food from wild plants. Agricultural societies emerged over the Woodland period between 1000 BCE to 1000 CE. Toward the end of this period, Wisconsin was the heartland of the "Effigy Mound culture", which built thousands of animal-shaped mounds across the landscape.
Between 1000 and 1500 CE, the Mississippian and Oneota cultures built substantial settlements including the fortified village at Aztalan in southeast Wisconsin. The Oneota may be the ancestors of the modern Ioway and Ho-Chunk tribes who shared the Wisconsin region with the Menominee at the time of European contact. Other Native American groups living in Wisconsin when Europeans first settled included the Ojibwa, Fox and Pottawatomie, who migrated to Wisconsin from the east between 1500 and 1700; the first European to visit what became Wisconsin was the French explorer Jean Nicolet. He canoed west from Georgian Bay through the Great Lakes in 1634, it is traditionally assumed that he came ashore near Green Bay at Red Banks. Pierre Radisson and Médard des Groseilliers visited Green Bay again in 1654–1666 and Chequamegon Bay in 1659–1660, where they traded for fur with local Native Americans. In 1673, Jacques Marquette and Louis Jolliet became the first to record a journey on the Fox-Wisconsin Waterway all the way to the Mississippi River near Prairie du Chien.
Frenchmen like Nicholas Perrot continued to ply the fur trade across Wisconsin through the 17th and 18th centuries, but the French made no permanent settlements in Wisconsin before Great Britain won control of the region following the French and Indian War in 1763. So, French traders continued to work in the region after the war, some, beginning with Charles de Langlade in 1764, settled in Wisconsin permanently, rather than returning to British-controlled Canada; the British took over Wisconsin during the French and Indian War, taking control of Green Bay in 1761 and gaining control of all of Wisconsin in 1763. Like the French, the British were interested in little but the fur trade. One notable event in the fur trading industry in Wisconsin occurred in 1791, when two free African Americans set up a fur trading post among the Menominee at present day Marinette; the first permanent settlers French Canadians, some Anglo-New Englanders and a few African American freedmen, arrived in Wisconsin while it was under British control.
Charles Michel de Langlade is recognized as the first settler, establishing a trading post at Green Bay in 1745, moving there permanently in 1764. Settlement began at Prairie du Chien around 1781; the French residents at the trading post in what is now Green Bay, referred to the t
