Cahokia is a settlement and former village in St. Clair County, Illinois, United States, founded as a colonial French mission in 1689. Located on the east side of the Mississippi River in the Greater St. Louis metropolitan area, as of the 2010 census, 15,241 people lived in the village. On May 6, 2021, the village was incorporated into the new city of Cahokia Heights.
The Illinois Confederation, also referred to as the Illiniwek or Illini, were made up of 12 to 13 tribes who lived in the Mississippi River Valley. Eventually member tribes occupied an area reaching from Lake Michicigao (Michigan) to Iowa, Illinois, Missouri, and Arkansas. The five main tribes were the Cahokia, Kaskaskia, Michigamea, Peoria, and Tamaroa. The spelling Illinois was derived from the transliteration by French explorers of iliniwe to the orthography of their own language. The tribes are estimated to have had tens of thousands of members, before the advancement of European contact in the 17th century that inhibited their growth and resulted in a marked decline in population.
Cahokia Mounds is the site of a pre-Columbian Native American city directly across the Mississippi River from present-day St. Louis. The state archaeology park lies in south-western Illinois between East St. Louis and Collinsville. The park covers 2,200 acres (890 ha), or about 3.5 square miles (9 km2), and contains about 80 manmade mounds, but the ancient city was much larger. At its apex around 1100 CE, the city covered about 6 square miles (16 km2), included about 120 earthworks in a wide range of sizes, shapes, and functions, and had a population of between 15,000 and 20,000 people.
The Kaskaskia were one of the indigenous peoples of the Northeastern Woodlands. They were one of about a dozen cognate tribes that made up the Illiniwek Confederation, also called the Illinois Confederation. Their longstanding homeland was in the Great Lakes region. Their first contact with Europeans reportedly occurred near present-day Green Bay, Wisconsin, in 1667 at a Jesuit mission station.
The Caddo people comprise the Caddo Nation of Oklahoma, a federally recognized tribe headquartered in Binger, Oklahoma. They speak the Caddo language.
The Illinois Country, also referred to as Upper Louisiana, was a vast region of New France claimed in the 1600s that later fell under Spanish and British control before becoming what is now part of the Midwestern United States. While the area claimed included the entire Upper Mississippi River watershed, French colonial settlement was concentrated along the Mississippi and Illinois Rivers in what is now the U.S. states of Illinois and Missouri, with outposts on the Wabash River in Indiana. Explored in 1673 from Green Bay to the Arkansas River by the Canadien expedition of Louis Jolliet and Jacques Marquette, the area was claimed by France. It was settled primarily from the Pays d'en Haut in the context of the fur trade, and in the establishment of missions from Canada by French Catholic religious orders. Over time, the fur trade took some French to the far reaches of the Rocky Mountains, especially along the branches of the broad Missouri River valley. The "Illinois" in the territory's name is a reference to the Illinois Confederation, a group of related Algonquian native peoples.
The Peoria are a Native American people. They are enrolled in the federally recognized Peoria Tribe of Indians of Oklahoma headquartered in Miami, Oklahoma.
The Tamaroa were a Native American people in the central Mississippi River valley of North America, and a member of the Illiniwek or Illinois Confederation of 12 or 13 tribes. The name "Tamaroa" is a derivative of the word tamarowa meaning "cut tail" in Illiniwek and relates to a totemic animal such as bear or wildcat. An Algonquian-speaking group, like the rest of the Illiniwek, they lived on both sides of the Mississippi River in the area of the confluence with the Illinois and Missouri Rivers. Tamaroan culture is presumed to be similar to that of the Kaskaskia, Peoria, and other Illinois tribes.
The Mississippian culture were collections of Native American societies that flourished in what is now the Midwestern, Eastern, and Southeastern United States from approximately 800 to 1600, varying regionally. It was known for building large, earthen platform mounds, and often other shaped mounds as well. It was composed of a series of urban settlements and satellite villages linked together by loose trading networks. The largest city was Cahokia, believed to be a major religious center, located in what is present-day southern Illinois.
Monks Mound is the largest Pre-Columbian earthwork in the Americas and the largest pyramid north of Mesoamerica. The beginning of its construction dates from 900 to 955 CE. Located at the Cahokia Mounds UNESCO World Heritage Site near Collinsville, Illinois, the mound size was calculated in 1988 as about 100 feet (30 m) high, 955 feet (291 m) long including the access ramp at the southern end, and 775 feet (236 m) wide. This makes Monks Mound roughly the same size at its base as the Great Pyramid of Giza. The perimeter of its base is larger than the Pyramid of the Sun at Teotihuacan. As a platform mound, the earthwork supported a wooden structure on the summit.
The American Bottom is the flood plain of the Mississippi River in the Metro East region of Southern Illinois, extending from Alton, Illinois, south to the Kaskaskia River. It is also sometimes called "American Bottoms". The area is about 175 square miles (450 km2), mostly protected from flooding in the 21st century by a levee and drainage canal system. Immediately across the river from St. Louis, Missouri, are industrial and urban areas, but nearby marshland, swamps, and the Horseshoe Lake are reminders of the Bottoms' riparian nature.
Indigenous peoples of the Northeastern Woodlands include Native American tribes and First Nation bands residing in or originating from a cultural area encompassing the northeastern and Midwest United States and southeastern Canada. It is part of a broader grouping known as the Eastern Woodlands. The Northeastern Woodlands is divided into three major areas: the Coastal, Saint Lawrence Lowlands, and Great Lakes-Riverine zones.
Spiro Mounds is an Indigenous archaeological site located in present-day eastern Oklahoma. The site was built by people from the Arkansas Valley Caddoan culture. that remains from an American Indian culture that was part of the major northern Caddoan Mississippian culture. The 80-acre site is located within a floodplain on the southern side of the Arkansas River. The modern town of Spiro developed approximately seven miles to the south.
Dickson Mounds is a Native American settlement site and burial mound complex near Lewistown, Illinois. It is located in Fulton County on a low bluff overlooking the Illinois River. It is a large burial complex containing at least two cemeteries, ten superimposed burial mounds, and a platform mound. The Dickson Mounds site was founded by 800 CE and was in use until after 1250 CE. The site is named in honor of chiropractor Don Dickson, who began excavating it in 1927 and opened a private museum that formerly operated on the site. Its exhibition of the 237 uncovered skeletons displayed by Dickson was closed in 1992 by then-Gov. Jim Edgar.
The Mitchigamea, Michigamea, or Michigamie were a tribe in the Illinois Confederation. Not much is known about them and their origin is uncertain. Originally they were said to be from Lake Michigan, perhaps the Chicago area. Mitchie Precinct, Monroe County in Southwestern Illinois takes its name from their transient presence nearby, north of the French Fort de Chartres in the American Bottom along the Mississippi. One of their villages in the American Bottom, inhabited from 1730 until 1752, is one of the region's premier archaeological sites; it is known as the "Kolmer Site".
The Caddoan Mississippian culture was a prehistoric Native American culture considered by archaeologists as a variant of the Mississippian culture. The Caddoan Mississippians covered a large territory, including what is now Eastern Oklahoma, Western Arkansas, Northeast Texas, Southwest Missouri and Northwest Louisiana of the United States.
Mississippian copper plates, or plaques, are plain and repousséd plates of beaten copper crafted by peoples of the various regional expressions of the Mississippian culture between 800 and 1600 CE. They have been found as artifacts in archaeological sites in the American Midwest and Southeast. The plates, found as far afield as Florida, Georgia, Illinois, Mississippi, Oklahoma, Tennessee, and Wisconsin, were instrumental in the development of the archaeological concept known as the Southeastern Ceremonial Complex. Some of the more notable examples are representations of raptorial birds and avian-themed dancing warriors.
The Kolmer Site is an archaeological site in the far southwest of the U.S. state of Illinois. Located near Kaskaskia and Prairie du Rocher in western Randolph County, it lies at the site of an early historic Indian village from the French period. Because it occupies a critical chronological and cultural position, it has been given national recognition as a historic site.
The Kaskaskia–Cahokia Trail was the first road in Illinois, running from Kaskaskia to Cahokia.
