127-1032: Founded in 1973, the Center for Louisiana Studies grew around the University's copies of the Louisiana Colonial Records Collection. Begun in 1967, the Collection attempts to draw together available microfilmed copies of any and all primary source records focused on the discovery, exploration, settlement, and development of the Mississippi Valley between 1682 and 1803. To date, over 1,000,000 pages of archival material have been photo-duplicated from French archives; over 1.5 million pages copied from Spanish archives; over 20,000 pages of documentary evidence from British depositories; and over 165,000 pages of material have been collected from various Louisiana sources. Together with

254-489: A collective noun (also describing First Nations, Inuit, and Métis) is a specific term of art used in some legal documents, including the Constitution Act, 1982 . Over time, as societal perceptions and government–indigenous relationships have shifted, many historical terms have changed definitions or been replaced as they have fallen out of favor. The use of the term "Indian" is frowned upon because it represents

381-667: A colonial state. The peopling of the Americas began when Paleolithic hunter-gatherers ( Paleo-Indians ) entered North America from the North Asian Mammoth steppe via the Beringia land bridge , which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26,000 to 19,000 years ago). These populations expanded south of

508-640: A connection to residential schools. Additionally, Indigenous respondents with higher HLS and HLASS scores had one or more negative health outcomes. While there are many studies that found an association between IHT and adverse health outcomes, scholars continue to suggest that it remains difficult to understand the impact of IHT. IHT needs to be systematically measured. Indigenous people also need to be understood in separate categories based on similar experiences, location, and background as opposed to being categorized as one monolithic group. For thousands of years, Indigenous peoples domesticated, bred, and cultivated

635-855: A few still considered uncontacted peoples . The Americas also host millions of individuals of mixed Indigenous, European, and sometimes African or Asian descent, historically referred to as mestizos in Spanish-speaking countries. In many Latin American nations, people of partial Indigenous descent constitute a majority or significant portion of the population, particularly in Central America , Mexico , Peru, Bolivia, Ecuador , Colombia , Venezuela , Chile , and Paraguay. Mestizos outnumber Indigenous peoples in most Spanish-speaking countries, according to estimates of ethnic cultural identification. However, since Indigenous communities in

762-476: A large array of plant species. These species now constitute between 50% and 60% of all crops in cultivation worldwide. In certain cases, the Indigenous peoples developed entirely new species and strains through artificial selection , as with the domestication and breeding of maize from wild teosinte grasses in the valleys of southern Mexico. Numerous such agricultural products retain their native names in

889-424: A large citizenry. Indigenous civilizations also displayed impressive accomplishments in astronomy and mathematics, including the most accurate calendar in the world. The domestication of maize or corn required thousands of years of selective breeding, and continued cultivation of multiple varieties was done with planning and selection, generally by women. Inuit, Yupik, Aleut, and Indigenous creation myths tell of

1016-542: A large mound of sand spanning the width of the river 55 feet below the surface, allowing fresh water and large cargo ships to pass over. Fresh river water flowing from the Mississippi into the Gulf of Mexico does not mix into the salt water immediately. The images from NASA 's MODIS show a large plume of fresh water, which appears as a dark ribbon against the lighter-blue surrounding waters. These images demonstrate that

1143-734: A length of 3,710 miles (5,971 km), making it the fourth longest river in the world after the Nile , Amazon , and Yangtze . When measured by the largest stream source (by water volume), the Ohio River , by extension the Allegheny River , would be the source, and the Mississippi would begin in Pennsylvania . At its source at Lake Itasca , the Mississippi River is about 3 feet (0.91 m) deep. The average depth of

1270-551: A multitude of ways because the Indigenous community and their history are diverse. Many studies (such as Whitbeck et al., 2014; Brockie, 2012; Anastasio et al., 2016; Clark & Winterowd, 2012; Tucker et al., 2016) have evaluated the impact of IHT on health outcomes of Indigenous communities from the United States and Canada. IHT is a difficult term to standardize and measure because of the vast and variable diversity of Indigenous people and their communities. Therefore, it

1397-478: A natural process known as avulsion or delta switching, the lower Mississippi River has shifted its final course to the mouth of the Gulf of Mexico every thousand years or so. This occurs because the deposits of silt and sediment begin to clog its channel, raising the river's level and causing it to eventually find a steeper, more direct route to the Gulf of Mexico. The abandoned distributaries diminish in volume and form what are known as bayous . This process has, over

1524-416: A pre-Columbian high of an estimated three million to some 300,000 in 1997. The Spanish Empire and other Europeans re-introduced horses to the Americas. Some of these animals escaped and began to breed and increase their numbers in the wild. The reintroduction of the horse , extinct in the Americas for over 7500 years, had a profound impact on Indigenous cultures in several regions, such as those of

1651-592: A second, more recent wave of migration several thousand years later and have much more recent genetic and cultural commonalities with the Indigenous peoples of Siberia . However, these groups are nonetheless considered "Indigenous peoples of the Americas". The term Amerindian , a portmanteau of "American Indian", was coined in 1902 by the American Anthropological Association . It has been controversial ever since its creation. It

1778-611: A threat to livestock. Several bird species, such as turkeys , Muscovy ducks , Puna ibis , and neotropic cormorants were domesticated by various peoples in Mesoamerica and South America to be used for poultry. In the Andean region, indigenous peoples domesticated llamas and alpacas to produce fiber and meat. The llama was the only beast of burden in the Americas before European colonization. Guinea pigs were domesticated from wild cavies to be raised for meat consumption in

1905-493: A variety of origins of their respective peoples. Some were "always there" or were created by gods or animals, some migrated from a specified compass point , and others came from "across the ocean". The European colonization of the Americas fundamentally changed the lives and cultures of the resident Indigenous peoples. Although the exact pre-colonization population count of the Americas is unknown, scholars estimate that Indigenous populations diminished by between 80% and 90% during

2032-666: A violent poison. Eventually, a Taíno Cacique named Enriquillo managed to hold out in the Baoruco Mountain Range for thirteen years, causing serious damage to the Spanish, Carib-held plantations and their Indian auxiliaries . Hearing of the seriousness of the revolt, Emperor Charles V (also King of Spain) sent Captain Francisco Barrionuevo to negotiate a peace treaty with the ever-increasing number of rebels. Two months later, after consultation with

2159-476: A vital transportation artery and communications link. In the 19th century, during the height of the ideology of manifest destiny , the Mississippi and several tributaries, most notably its largest, the Ohio and Missouri , formed pathways for the western expansion of the United States. The river also became the subject of American literature , particularly in the writings of Mark Twain . Formed from thick layers of

2286-437: A whole, in general, most Indigenous peoples prefer to be identified by the name of their specific nation, tribe, or band. Early settlers often adopted terms that some tribes used for each other, not realizing these were derogatory terms used by enemies. When discussing broader subsets of peoples, naming has often been based on shared language, region, or historical relationship. Many English exonyms have been used to refer to

2413-534: A whole. Since the 1970s, the word "Indigenous", which is capitalized when referring to people, has gradually emerged as a favored umbrella term. The capitalization is to acknowledge that Indigenous peoples have cultures and societies that are equal to Europeans, Africans, and Asians. This has recently been acknowledged in the AP Stylebook . Some consider it improper to refer to Indigenous people as "Indigenous Americans" or to append any colonial nationality to

2540-861: Is 208,200 cu ft/s (5,900 m /s). Thus, by volume, the main branch of the Mississippi River system at Cairo can be considered to be the Ohio River (and the Allegheny River further upstream), rather than the Middle Mississippi. In addition to the Ohio River , the major tributaries of the Lower Mississippi River are the White River , flowing in at the White River National Wildlife Refuge in east-central Arkansas;

2667-533: Is a common term, though nativos or pueblos nativos ('native peoples') may also be heard; moreover, aborigen ('aborigine') is used in Argentina and pueblos originarios ('original peoples') is common in Chile . In Brazil, indígenas and povos originários ('Indigenous peoples') are common formal-sounding designations, while índio ('Indian') is still the more often heard term (the noun for

The Mississippi River is known as the Middle Mississippi from the Upper Mississippi River's confluence with the Missouri River at St. Louis, Missouri , for 190 miles (310 km) to its confluence with the Ohio River at Cairo, Illinois . The Middle Mississippi is relatively free-flowing. From St. Louis to

2921-416: Is an arduous task to assign an operational definition and systematically collect data when studying IHT. Many of the studies that incorporate IHT measure it in different ways, making it hard to compile data and review it holistically. This is an important point that provides context for the following studies that attempt to understand the relationship between IHT and potential adverse health impacts. Some of

3048-498: Is called the Lower Mississippi River from its confluence with the Ohio River to its mouth at the Gulf of Mexico, a distance of about 1,000 miles (1,600 km). At the confluence of the Ohio and the Middle Mississippi, the long-term mean discharge of the Ohio at Cairo, Illinois is 281,500 cubic feet per second (7,970 cubic meters per second), while the long-term mean discharge of the Mississippi at Thebes, Illinois (just upriver from Cairo)

3175-912: Is controlled and managed as a series of pools created by 26 locks and dams. The Upper Mississippi River is joined by the Minnesota River at Fort Snelling in the Twin Cities ; the St. Croix River near Prescott, Wisconsin ; the Cannon River near Red Wing, Minnesota ; the Zumbro River at Wabasha, Minnesota ; the Black , La Crosse , and Root rivers in La Crosse, Wisconsin ; the Wisconsin River at Prairie du Chien, Wisconsin ;

3302-546: Is entirely within the United States; the total drainage basin is 1,151,000 sq mi (2,980,000 km ), of which only about one percent is in Canada. The Mississippi ranks as the world's tenth-largest river by discharge flow, and the largest in North America. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Many were hunter-gatherers , but some, such as

3429-551: Is general agreement that the Americas were first settled from Asia, the pattern of migration and the place(s) of origin in Eurasia of the peoples who migrated to the Americas remain unclear. The traditional theory is that Ancient Beringians moved when sea levels were significantly lowered due to the Quaternary glaciation , following herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between

3556-520: Is largely a multi-thread stream with many bars and islands. From its confluence with the St. Croix River downstream to Dubuque, Iowa , the river is entrenched, with high bedrock bluffs lying on either side. The height of these bluffs decreases to the south of Dubuque, though they are still significant through Savanna, Illinois . This topography contrasts strongly with the Lower Mississippi, which

3683-539: Is the only true waterfall on the entire Mississippi River. The water elevation continues to drop steeply as it passes through the gorge carved by the waterfall. After the completion of the St. Anthony Falls Lock and Dam in 1963, the river's head of navigation moved upstream, to the Coon Rapids Dam . However, the Locks were closed in 2015 to control the spread of invasive Asian carp , making Minneapolis once again

3810-570: The Archaic period of North American cultures. Technology had advanced to the point where pottery had started to become common and the small-scale felling of trees had become feasible. Concurrently, the Archaic Indigenous peoples began using fire in a controlled manner. They carried out the intentional burning of vegetation to mimic the effects of natural fires that tended to clear forest understories. It made travel easier and facilitated

3937-880: The Arkansas River , joining the Mississippi at Arkansas Post ; the Big Black River in Mississippi; and the Yazoo River , meeting the Mississippi at Vicksburg, Mississippi . Deliberate water diversion at the Old River Control Structure in Louisiana allows the Atchafalaya River in Louisiana to be a major distributary of the Mississippi River, with 30% of the combined flow of the Mississippi and Red Rivers flowing to

The Fuegian dog was a domesticated variation of the culpeo that was raised by several cultures in Tierra del Fuego , like the Selk'nam and the Yahgan . It was exterminated by Argentine and Chilean settlers, due to supposedly posing as

4191-771: The Great Plains , the Northwest Plateau , the Great Basin , Aridoamerica , the Gran Chaco and the Southern Cone . By domesticating horses, some tribes had great success: horses enabled them to expand their territories, exchange more goods with neighboring tribes, and more easily capture game , such as bison . According to Erin McKenna and Scott L. Pratt, the Indigenous population of the Americas

4318-577: The Gulf of Mexico , part of the Atlantic Ocean. The total catchment of the Mississippi River covers nearly 40% of the landmass of the continental United States. The highest point within the watershed is also the highest point of the Rocky Mountains , Mount Elbert at 14,440 feet (4,400 m). In the United States, the Mississippi River drains the majority of the area between the crest of

The river either borders or passes through the states of Minnesota , Wisconsin , Iowa , Illinois , Missouri , Kentucky , Tennessee , Arkansas , Mississippi , and Louisiana . The main stem

4572-503: The Inca Civil War of 1529–1532. Smallpox was only the first epidemic. Typhus (probably) in 1546, influenza and smallpox together in 1558, smallpox again in 1589, diphtheria in 1614, and measles in 1618—all ravaged the remains of Inca culture. Smallpox killed millions of native inhabitants of Mexico. Unintentionally introduced at Veracruz with the arrival of Pánfilo de Narváez on 23 April 1520, smallpox ravaged Mexico in

4699-573: The Laurentide and Cordilleran ice sheets. Another route proposed is that, either on foot or using boats , they migrated down the Pacific coast to South America as far as Chile . Any archaeological evidence of coastal occupation during the last Ice Age would now have been covered by the sea level rise , up to a hundred metres since then. While technically referring to the era before Christopher Columbus ' voyages of 1492 to 1504, in practice

The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians . Indigenous peoples of the Americas have been linked to Siberian populations by proposed linguistic factors , the distribution of blood types , and in genetic composition as reflected by molecular data, such as DNA . While there

4953-607: The Library of Congress and the University of Memphis , the Center is one of only three repositories for the colonial documents of France in the United States . Another important impetus for the founding of the Center was the creation of The University of Southwestern Louisiana History Series (U.S.L. being the former name of The University of Louisiana).

5334-603: The Minnesota River , James River , and Milk River valleys. When the ice sheet completely retreated, many of these "temporary" rivers found paths to Hudson Bay or the Arctic Ocean, leaving the Mississippi Basin with many features "over-sized" for the existing rivers to have carved in the same time period. Ice sheets during the Illinoian Stage , about 300,000 to 132,000 years before present, blocked

The remaining 29 dams, beginning in downtown Minneapolis, all contain locks and were constructed to improve commercial navigation of the upper river. Taken as a whole, these 43 dams significantly shape the geography and influence the ecology of the upper river. Beginning just below Saint Paul, Minnesota , and continuing throughout

5969-418: The history and prehistory of the Americas before the appearance of significant European and African influences on the American continents, spanning the time of the original arrival in the Upper Paleolithic to European colonization during the early modern period . The Norte Chico civilization (in present-day Peru) is one of the defining six original civilizations of the world, arising independently around

6096-422: The most recent Ice Age . The southernmost extent of this enormous glaciation extended well into the present-day United States and Mississippi basin. When the ice sheet began to recede, hundreds of feet of rich sediment were deposited, creating the flat and fertile landscape of the Mississippi Valley. During the melt, giant glacial rivers found drainage paths into the Mississippi watershed, creating such features as

6223-448: The residential school ancestry studies ask respondents if their parents, grandparents, great-grandparents, or "elders from their community" went to a residential school to understand if family or community history in residential schools is associated with negative health outcomes. In a comprehensive review of the research literature, Joseph Gone and colleagues compiled and compared outcomes for studies using these IHT measures relative to

6350-431: The " West Indies " (or " Antilles "), a name that is still used to describe the islands. This led to the blanket term "Indies" and "Indians" ( Spanish : indios ; Portuguese : índios ; French : indiens ; Dutch : indianen ) for the Indigenous inhabitants, which implied some kind of ethnic or cultural unity among the Indigenous peoples of the Americas. This unifying concept, codified in law, religion, and politics,

6604-439: The 1520s, possibly killing over 150,000 in Tenochtitlán (the heartland of the Aztec Empire) alone, and aiding in the victory of Hernán Cortés over the Aztec Empire at Tenochtitlan (present-day Mexico City) in 1521. There are many factors as to why Indigenous peoples suffered such immense losses from Afro-Eurasian diseases. Many Old World diseases, like cow pox, are acquired from domesticated animals that are not indigenous to

6731-473: The 16th century were Constantinople and Paris with 300,000 and 200,000 inhabitants respectively. The population in London, Madrid, and Rome hardly exceeded 50,000 people. In 1523, right around the time of the Spanish conquest, the entire population in the country of England was just under three million people. This fact speaks to the level of sophistication, agriculture, governmental procedure, and rule of law that existed in Tenochtitlan, needed to govern over such

6858-406: The 18th century, the river was set by the Treaty of Paris as, for the most part, the western border of the new United States. With the Louisiana Purchase and the country's westward expansion, it became a convenient boundary line between the western and eastern halves of the country. This is reflected in the Gateway Arch in St. Louis, which was designed to symbolize the opening of the West, and

6985-423: The 20th century, the Mississippi River has also experienced major pollution and environmental problems — most notably elevated nutrient and chemical levels from agricultural runoff, the primary contributor to the Gulf of Mexico dead zone . The word Mississippi itself comes from Misi zipi , the French rendering of the Anishinaabe ( Ojibwe or Algonquin ) name for the river, Misi-ziibi (Great River). In

They had no immunity to European diseases, so outbreaks of measles and smallpox ravaged their population. One such outbreak occurred in a camp of enslaved Africans, where smallpox spread to the nearby Taíno population and reduced their numbers by 50%. Increasing punishment of

7239-462: The Americas are defined by cultural identification and kinship rather than ancestry or race , mestizos are typically not counted among the Indigenous population unless they speak an Indigenous language or identify with a specific Indigenous culture. Additionally, many individuals of wholly Indigenous descent who do not follow Indigenous traditions or speak an Indigenous language have been classified or self-identify as mestizo due to assimilation into

7366-416: The Americas have been more vocal about how they want to be addressed, pushing to suppress the use of terms widely considered to be obsolete, inaccurate, or racist . During the latter half of the 20th century and the rise of the Indian rights movement , the United States federal government responded by proposing the use of the term " Native American ", to recognize the primacy of Indigenous peoples' tenure in

7493-899: The Americas, with significant populations in countries such as Bolivia , Canada , Chile , Colombia , Ecuador , Guatemala , Mexico , Peru , and the United States . There are at least 1,000 different indigenous languages spoken across the Americas, with 574 federally recognized tribes in the US alone. Some languages, including Quechua , Arawak , Aymara , Guaraní , Mayan , and Nahuatl , have millions of speakers and are recognized as official by governments in Bolivia , Peru , Paraguay , and Greenland . Indigenous peoples, whether residing in rural or urban areas, often maintain aspects of their cultural practices, including religion , social organization , and subsistence practices. Over time, these cultures have evolved, preserving traditional customs while adapting to modern needs. Some Indigenous groups remain relatively isolated from Western culture , with

Many of the Old World diseases that were brought over to the Americas were diseases, like yellow fever , that were relatively manageable if infected as a child, but were deadly if infected as an adult. Children could often survive the disease, resulting in immunity to the disease for

Like Indigenous peoples, these African people, newly exposed to European diseases, lacked any inherited resistance to the diseases of Europe. In 1520, an African who had been infected with smallpox had arrived in Yucatán. By 1558, the disease had spread throughout South America and had arrived at

8382-588: The Gulf of Mexico by this route, rather than continuing down the Mississippi's current channel past Baton Rouge and New Orleans on a longer route to the Gulf. Although the Red River was once an additional tributary, its water now flows separately into the Gulf of Mexico through the Atchafalaya River. The Mississippi River has the world's fourth-largest drainage basin ("watershed" or "catchment"). The basin covers more than 1,245,000 square miles (3,220,000 km ), including all or parts of 32 U.S. states and two Canadian provinces. The drainage basin empties into

8509-409: The Gulf. The Mississippi River empties into the Gulf of Mexico about 100 miles (160 km) downstream from New Orleans. Measurements of the length of the Mississippi from Lake Itasca to the Gulf of Mexico vary somewhat, but the United States Geological Survey 's number is 2,340 miles (3,766 km). The retention time from Lake Itasca to the Gulf is typically about 90 days; while speed varies along

Timeline of outflow course changes In March 1876, the Mississippi suddenly changed course near the settlement of Reverie, Tennessee , leaving a small part of Tipton County, Tennessee , attached to Arkansas and separated from the rest of Tennessee by the new river channel. Since this event was an avulsion , rather than the effect of incremental erosion and deposition,

Some of these names were based on foreign language terms used by earlier explorers and colonists, while others resulted from the colonists' attempts to translate or transliterate endonyms from the native languages. Other terms arose during periods of conflict between the colonists and Indigenous peoples. Since the late 20th century, Indigenous peoples in

Some 90 percent of the native population near Massachusetts Bay Colony died of smallpox in an epidemic in 1617–1619. In 1633, in Fort Orange (New Netherland) , the Native Americans there were exposed to smallpox because of contact with Europeans. As it had done elsewhere, the virus wiped out entire population groups of Native Americans. It reached Lake Ontario in 1636, and

This area is still quite active seismically. Four great earthquakes in 1811 and 1812 , estimated at 8 on the Richter magnitude scale , had tremendous local effects in the then sparsely settled area, and were felt in many other places in

9652-1164: The Mississippi River. Indigenous peoples of the Americas In the Americas , indigenous peoples comprise the two continents' pre-Columbian inhabitants prior to European settlement in the 15th century, as well as the ethnic groups that identify with the pre-Columbian population of the Americas as such. These populations exhibit significant diversity; some Indigenous peoples were historically hunter-gatherers , while others practiced agriculture and aquaculture . Various Indigenous societies developed complex social structures , including pre-contact monumental architecture, organized cities , city-states , chiefdoms , states , kingdoms , republics , confederacies , and empires . These societies possessed varying levels of knowledge in fields such as engineering , architecture , mathematics , astronomy , writing , physics , medicine , agriculture , irrigation , geology , mining , metallurgy , art , sculpture , and goldsmithing . Indigenous peoples continue to inhabit many regions of

9779-456: The Mississippi near Rock Island, Illinois, diverting it to its present channel farther to the west, the current western border of Illinois. The Hennepin Canal roughly follows the ancient channel of the Mississippi downstream from Rock Island to Hennepin, Illinois . South of Hennepin, to Alton, Illinois , the current Illinois River follows the ancient channel used by the Mississippi River before

9906-640: The Ohio River confluence, the Middle Mississippi falls 220 feet (67 m) over 180 miles (290 km) for an average rate of 1.2 feet per mile (23 cm/km). At its confluence with the Ohio River, the Middle Mississippi is 315 feet (96 m) above sea level. Apart from the Missouri and Meramec rivers of Missouri and the Kaskaskia River of Illinois, no major tributaries enter the Middle Mississippi River. The Mississippi River

10033-610: The Ohio to the Gulf of Mexico. The Upper Mississippi runs from its headwaters to its confluence with the Missouri River at St. Louis, Missouri. It is divided into two sections: The source of the Upper Mississippi branch is traditionally accepted as Lake Itasca , 1,475 feet (450 m) above sea level in Itasca State Park in Clearwater County, Minnesota . The name Itasca was chosen to designate

10160-665: The Plata basin. Colonist violence towards Indigenous peoples accelerated the loss of lives. European colonists perpetrated massacres on the Indigenous peoples and enslaved them. According to the U.S. Bureau of the Census (1894), the North American Indian Wars of the 19th century had a known death toll of about 19,000 Europeans and 30,000 Native Americans, and an estimated total death toll of 45,000 Native Americans. The first Indigenous group encountered by Columbus,

10287-748: The South-Asian nationality being indiano ), but for the past 10 years has been considered offensive and pejorative. Aborígene and nativo are rarely used in Brazil in Indigenous-specific contexts (e.g., aborígene is usually understood as the ethnonym for Indigenous Australians ). The Spanish and Portuguese equivalents to Indian , nevertheless, could be used to mean any hunter-gatherer or full-blooded Indigenous person, particularly to continents other than Europe or Africa—for example, indios filipinos . Indigenous peoples of

10414-474: The Taínos for revolting against forced labor, despite measures put in place by the encomienda , which included religious education and protection from warring tribes, eventually led to the last great Taíno rebellion (1511–1529). Following years of mistreatment, the Taínos began to adopt suicidal behaviors, with women aborting or killing their infants and men jumping from cliffs or ingesting untreated cassava ,

10541-464: The U.S.L. History Series from its establishment in 1970 until the fifteenth and final title in 1985. This Series established the Center for Louisiana Studies as a significant regional publishing center. The Center received a significant boost with the publication of The Courthouses of Louisiana and The Cajuns: Essays on their History and Culture . Although sales of these titles were modest by publishing standards, that small amount nevertheless allowed

10668-616: The UL Press, a university press that is currently an introductory member of the Association of University Presses . Mississippi Valley The Mississippi River is the primary river of the largest drainage basin in the United States . From its traditional source of Lake Itasca in northern Minnesota , it flows generally south for 2,340 miles (3,766 km) to the Mississippi River Delta in

10795-568: The United States are commonly known as Native Americans , Indians, as well as Alaska Natives . The term "Indian" is still used in some communities and remains in use in the official names of many institutions and businesses in Indian Country . The various nations, tribes, and bands of Indigenous peoples of the Americas have differing preferences in terminology for themselves. While there are regional and generational variations in which umbrella terms are preferred for Indigenous peoples as

10922-546: The Upper Mississippi River is the Upper St. Anthony Falls Lock and Dam in Minneapolis. Above the dam, the river's elevation is 799 feet (244 m). Below the dam, the river's elevation is 750 feet (230 m). This 49-foot (15 m) drop is the largest of all the Mississippi River locks and dams. The origin of the dramatic drop is a waterfall preserved adjacent to the lock under an apron of concrete. Saint Anthony Falls

11049-604: The Upper Mississippi is a simple steel culvert, through which the river (locally named "Nicolet Creek") flows north from Lake Nicolet under "Wilderness Road" to the West Arm of Lake Itasca, within Itasca State Park . The earliest bridge across the Mississippi River was built in 1855. It spanned the river in Minneapolis where the current Hennepin Avenue Bridge is located. No highway or railroad tunnels cross under

11176-555: The areas drained by them. Denser salt water from the Gulf of Mexico forms a salt wedge along the river bottom near the mouth of the river, while fresh water flows near the surface. In drought years, with less fresh water to push it out, salt water can travel many miles upstream—64 miles (103 km) in 2022—contaminating drinking water supplies and requiring the use of desalination . The United States Army Corps of Engineers constructed "saltwater sills" or "underwater levees" to contain this in 1988, 1999, 2012, and 2022. This consists of

11303-680: The contact and colonization period and were documented in historical accounts of the time. A few, such as the Mayan, Olmec, Mixtec, Aztec , and Nahua peoples , had their written languages and records. However, the European colonists of the time worked to eliminate non-Christian beliefs and burned many pre-Columbian written records. Only a few documents remained hidden and survived, leaving contemporary historians with glimpses of ancient culture and knowledge. According to both Indigenous and European accounts and documents, American civilizations before and at

11430-427: The course of the river, this gives an overall average of around 26 mi (42 km) per day, or 1 mi (1.6 km) per hour. The stream gradient of the entire river is 0.01%, a drop of 450 m over 3,766 km. The Mississippi River discharges at an annual average rate of between 200 and 700 thousand cubic feet per second (6,000 and 20,000 m /s). The Mississippi is the fourteenth largest river in

11557-466: The delta of the Chippewa River of Wisconsin as it enters the Upper Mississippi, is more than 2 miles (3.2 km) wide. By the time the Upper Mississippi reaches Saint Paul , Minnesota, below Lock and Dam No. 1, it has dropped more than half its original elevation and is 687 feet (209 m) above sea level. From St. Paul to St. Louis, Missouri, the river elevation falls much more slowly and

11684-592: The depth averages 50–100 feet (15–30 m) deep. The deepest part of the river is in New Orleans, where it reaches 200 feet (61 m) deep. The Mississippi River runs through or along 10 states, from Minnesota to Louisiana , and is used to define portions of these states' borders, with Wisconsin , Illinois , Kentucky , Tennessee , and Mississippi along the east side of the river, and Iowa , Missouri , and Arkansas along its west side. Substantial parts of both Minnesota and Louisiana are on either side of

11811-504: The dominant Hispanic culture . In recent years, the self-identified Indigenous population in many countries has increased as individuals reclaim their heritage amid rising Indigenous-led movements for self-determination and social justice . Application of the term " Indian " originated with Christopher Columbus , who, in his search for India , thought that he had arrived in the East Indies . The islands came to be known as

11938-630: The first centuries of European colonization. Most scholars estimate a pre-colonization population of around 50 million, with other scholars arguing for an estimate of 100 million. Estimates reach as high as 145 million. Epidemics ravaged the Americas with diseases, such as smallpox , measles , and cholera , which the early colonists brought from Europe. The spread of infectious diseases was slow initially, as most Europeans were not actively or visibly infected, due to inherited immunity from generations of exposure to these diseases in Europe. This changed when

12065-495: The focus on the " Trans-Mississippi " region in the Trans-Mississippi Exposition . Regional landmarks are often classified in relation to the river, such as "the highest peak east of the Mississippi " or "the oldest city west of the Mississippi". The FCC also uses it as the dividing line for broadcast call-signs , which begin with W to the east and K to the west, overlapping in media markets along

12192-512: The growth of herbs and berry-producing plants, which were important both for food and for medicines. In the Mississippi River valley, Europeans noted that Native Americans managed groves of nut and fruit trees not far from villages and towns and their gardens and agricultural fields. They would have used prescribed burning farther away, in forest and prairie areas. Many crops first domesticated by Indigenous peoples are now produced and used globally, most notably maize (or "corn") arguably

12319-435: The health outcomes of Indigenous peoples. The study defined negative health outcomes to include such concepts as anxiety , suicidal ideation , suicide attempts , polysubstance abuse , PTSD , depression , binge eating , anger, and sexual abuse. The connection between IHT and health conditions is complicated because of the difficult nature of measuring IHT, the unknown directionality of IHT and health outcomes, and because

12446-503: The hotspot's activity declined, the crust beneath the embayment region cooled, contracted and subsided to a depth of 2.6 km, and around 80 million years ago the Reelfoot Rift formed a trough that was flooded by the Gulf of Mexico . As sea levels dropped, the Mississippi and other rivers extended their courses into the embayment , which gradually became filled with sediment with the Mississippi River at its center. Through

12573-570: The imposition and restriction of Indigenous peoples and cultures by the Canadian Government. The terms "Native" and " Eskimo " are generally regarded as disrespectful (in Canada), and so are rarely used unless specifically required. While "Indigenous peoples" is the preferred term, many individuals or communities may choose to describe their identity using a different term. The Métis people of Canada can be contrasted, for instance, to

12700-707: The lands of the Iroquois by 1679. During the 1770s smallpox killed at least 30% of the West Coast Native Americans. The 1775–82 North American smallpox epidemic and the 1837 Great Plains smallpox epidemic brought devastation and drastic population depletion among the Plains Indians . In 1832 the federal government of the United States established a smallpox vaccination program for Native Americans ( The Indian Vaccination Act of 1832 ). The Indigenous peoples in Brazil declined from

12827-402: The last two decades, this number was only 160 million short tons (145 million metric tons) per year. The reduction in sediment transported down the Mississippi River is the result of engineering modification of the Mississippi, Missouri, and Ohio rivers and their tributaries by dams, meander cutoffs , river-training structures, and bank revetments and soil erosion control programs in

12954-502: The lower 10 miles (16 km) of the Kaskaskia River, forming a new Mississippi channel and cutting off the town from the rest of the state. Later flooding destroyed most of the remaining town, including the original State House. Today, the remaining 2,300 acres (930 ha) island and community of 14 residents is known as an enclave of Illinois and is accessible only from the Missouri side. The New Madrid Seismic Zone , along

13081-476: The methodologies to measure IHT include a "Historical Losses Scale" (HLS), "Historical Losses Associated Symptoms Scale" (HLASS), and residential school ancestry studies. HLS uses a survey format that includes "12 kinds of historical losses", such as loss of language and loss of land and asks participants how often they think about those losses. The HLASS includes 12 emotional reactions, and asks participants how they feel when they think about these losses. Lastly,

13208-887: The most important crop in the world. Other significant crops include cassava ; chia ; squash (pumpkins, zucchini, marrow , acorn squash , butternut squash ); the pinto bean , Phaseolus beans including most common beans , tepary beans , and lima beans ; tomatoes ; potatoes ; sweet potatoes ; avocados ; peanuts ; cocoa beans (used to make chocolate ); vanilla ; strawberries ; pineapples ; peppers (species and varieties of Capsicum , including bell peppers , jalapeños , paprika , and chili peppers ); sunflower seeds ; rubber ; brazilwood ; chicle ; tobacco ; coca ; blueberries , cranberries , and some species of cotton . Studies of contemporary Indigenous environmental management—including agro-forestry practices among Itza Maya in Guatemala and hunting and fishing among

13335-458: The nation. As may be expected among people of over 400 different cultures in the US alone, not all of the people intended to be described by this term have agreed on its use or adopted it. No single group naming convention has been accepted by all Indigenous peoples in the Americas. Most prefer to be addressed as people of their tribe or nations when not speaking about Native Americans/American Indians as

13462-449: The new river channel, contiguous with the adjacent state. Also, due to a meander in the river, a small part of western Kentucky is contiguous with Tennessee but isolated from the rest of its state. Many of the communities along the Mississippi River are listed below; most have either historic significance or cultural lore connecting them to the river. They are sequenced from the source of the river to its end. The road crossing highest on

13589-549: The past 5,000 years, caused the coastline of south Louisiana to advance toward the Gulf from 15 to 50 miles (24 to 80 km). The currently active delta lobe is called the Birdfoot Delta, after its shape, or the Balize Delta , after La Balize, Louisiana , the first French settlement at the mouth of the Mississippi. The current form of the Mississippi River basin was largely shaped by the Laurentide Ice Sheet of

13716-549: The plume did not mix with the surrounding sea water immediately. Instead, it stayed intact as it flowed through the Gulf of Mexico, into the Straits of Florida , and entered the Gulf Stream . The Mississippi River water rounded the tip of Florida and traveled up the southeast coast to the latitude of Georgia before finally mixing in so thoroughly with the ocean that it could no longer be detected by MODIS. Over geologic time,

13843-774: The rest of their lives. But contact with adult populations without this childhood or inherited immunity would result in these diseases proving fatal. Colonization of the Caribbean led to the destruction of the Arawaks of the Lesser Antilles . Their culture was destroyed by 1650. Only 500 had survived by the year 1550, though the bloodlines continued through to the modern populace. In Amazonia, Indigenous societies weathered, and continue to suffer, centuries of colonization and genocide. Contact with European diseases such as smallpox and measles killed between 50 and 67 percent of

13970-612: The river's silt deposits, the Mississippi embayment is one of the most fertile regions of the United States; steamboats were widely used in the 19th and early 20th centuries to ship agricultural and industrial goods. During the American Civil War , the Mississippi's capture by Union forces marked a turning point towards victory , due to the river's strategic importance to the Confederate war effort. Because of

14097-479: The river, although the Mississippi defines part of the boundary of each of these states. In all of these cases, the middle of the riverbed at the time the borders were established was used as the line to define the borders between adjacent states. In various areas, the river has since shifted, but the state borders have not changed, still following the former bed of the Mississippi River as of their establishment, leaving several small isolated areas of one state across

14224-552: The river. Due to its size and importance, it has been nicknamed The Mighty Mississippi River or simply The Mighty Mississippi . The Mississippi River can be divided into three sections: the Upper Mississippi , the river from its headwaters to the confluence with the Missouri River; the Middle Mississippi, which is downriver from the Missouri to the Ohio River; and the Lower Mississippi , which flows from

14351-540: The same time as that of Egypt . Many later pre-Columbian civilizations achieved great complexity, with hallmarks that included permanent or urban settlements, agriculture, engineering, astronomy, trade, civic and monumental architecture, and complex societal hierarchies . Some of these civilizations had long faded by the time of the first significant European and African arrivals (ca. late 15th–early 16th centuries), and are known only through oral history and through archaeological investigations. Others were contemporary with

14478-400: The site of the head of navigation of the river. The Upper Mississippi has a number of natural and artificial lakes, with its widest point being Lake Winnibigoshish , near Grand Rapids, Minnesota , over 11 miles (18 km) across. Lake Onalaska , created by Lock and Dam No. 7 , near La Crosse, Wisconsin , is more than 4 miles (6.4 km) wide. Lake Pepin , a natural lake formed behind

14605-532: The state line still follows the old channel. The town of Kaskaskia, Illinois once stood on a peninsula at the confluence of the Mississippi and Kaskaskia (Okaw) Rivers . Founded as a French colonial community, it later became the capital of the Illinois Territory and was the first state capital of Illinois until 1819. Beginning in 1844, successive flooding caused the Mississippi River to slowly encroach east. A major flood in 1881 caused it to overtake

14732-412: The substantial growth of cities and the larger ships and barges that replaced steamboats, the first decades of the 20th century saw the construction of massive engineering works such as levees , locks and dams , often built in combination. A major focus of this work has been to prevent the lower Mississippi from shifting into the channel of the Atchafalaya River and bypassing New Orleans . Since

14859-474: The term Indigenous people used in the various samples comprises a huge population of individuals with drastically different experiences and histories. That being said some studies such as Bombay, Matheson, and Anisman (2014), Elias et al. (2012), and Pearce et al. (2008) found that Indigenous respondents with a connection to residential schools have more negative health outcomes (e.g., suicide ideation, suicide attempts, and depression) than those who did not have

14986-497: The term because Indigenous cultures existed before European colonization. Indigenous groups have territorial claims that are different from modern national and international borders, and when labeled as part of a country, their traditional lands are not acknowledged. Some who have written guidelines consider it more appropriate to describe an Indigenous person as "living in" or "of" the Americas, rather than calling them "American"; or simply calling them "Indigenous" without any addition of

15113-569: The term usually includes the history of Indigenous cultures until Europeans either conquered or significantly influenced them. "Pre-Columbian" is used especially often in the context of discussing the pre-contact Mesoamerican Indigenous societies : Olmec ; Toltec ; Teotihuacano ' Zapotec ; Mixtec ; Aztec and Maya civilizations ; and the complex cultures of the Andes : Inca Empire , Moche culture , Muisca Confederation , and Cañari . The Pre-Columbian era refers to all period subdivisions in

15240-458: The time of European encounter had achieved great complexity and many accomplishments. For instance, the Aztecs built one of the largest cities in the world, Tenochtitlan (the historical site of what would become Mexico City ), with an estimated population of 200,000 for the city proper and a population of close to five million for the extended empire. By comparison, the largest European cities in

15367-573: The upper and lower river, the Mississippi is further controlled by thousands of wing dikes that moderate the river's flow in order to maintain an open navigation channel and prevent the river from eroding its banks. The head of navigation on the Mississippi is the St. Anthony Falls Lock. Before the Coon Rapids Dam in Coon Rapids, Minnesota , was built in 1913, steamboats could occasionally go upstream as far as Saint Cloud, Minnesota , depending on river conditions. The uppermost lock and dam on

15494-479: The world by volume. On average, the Mississippi has 8% the flow of the Amazon River , which moves nearly 7 million cubic feet per second (200,000 m /s) during wet seasons. Before 1900, the Mississippi River transported an estimated 440 million short tons (400 million metric tons) of sediment per year from the interior of the United States to coastal Louisiana and the Gulf of Mexico. During

15621-456: Was 145 million in the late 15th and by the late 17th century, had been reduced to 15 million due to epidemics , wars, massacres, mass rapes , starvation, and enslavement. Indigenous historical trauma (IHT) is the trauma that can accumulate across generations and develop as a result of the historical ramifications of colonization and is linked to mental and physical health hardships and population decline. IHT affects many different people in

15748-642: Was cultivated as long as 10,000 years ago. According to Linda Newson , "It is clear that in pre-Columbian times some groups struggled to survive and often suffered food shortages and famines , while others enjoyed a varied and substantial diet." Persistent drought around AD 850 coincided with the collapse of the Classic Maya civilization, and the famine of One Rabbit (AD 1454) was a major catastrophe in Mexico. Indigenous peoples of North America began practicing farming approximately 4,000 years ago, late in

15875-603: Was immediately rejected by some leading members of the Association, and, while adopted by many, it was never universally accepted. While never popular in Indigenous communities themselves, it remains a preferred term among some anthropologists, notably in some parts of Canada and the English-speaking Caribbean . " Indigenous peoples in Canada " is used as the collective name for First Nations , Inuit , and Métis . The term Aboriginal peoples as

16002-505: Was not originally accepted by the myriad groups of Indigenous peoples themselves but has since been embraced or tolerated by many over the last two centuries. The term "Indian" generally does not include the culturally and linguistically distinct Indigenous peoples of the Arctic regions of the Americas, including the Aleuts , Inuit , or Yupik peoples . These peoples entered the continent as

16129-517: Was the overwhelming cause of the population decline of the Indigenous peoples. After initial contact with Europeans and Africans, Old World diseases caused the deaths of 90 to 95% of the native population of the New World in the following 150 years. Smallpox killed from one-third to half of the native population of Hispaniola in 1518. By killing the Incan ruler Huayna Capac , smallpox caused
