The History of the Illinois Country from 1673-1782.

The Illinois Country (1673-1782), sometimes referred to as Upper Louisiana, was the vast region of "New France" (hereinafter called Canada). These names generally referred to the entire Upper Mississippi River watershed. The French colonial settlement was concentrated along the Mississippi and Illinois Rivers in what is now the states of Illinois and Missouri, with outposts in Indiana.

The word "Mississippi" comes from the Ojibwe Indian Tribe (Algonquian language family) word "Messipi" or "misi-ziibi," which means "Great River" or "Gathering of Waters." French explorers, hearing the Ojibwe word for the river, recorded it in their own language with a similar pronunciation. The Potawatomi (Algonquian language family) pronounced "Mississippi" as the French said it, "Sinnissippi," which was given the meaning "Rocky Waters."

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 Païs d'en Haut [French: "up country" or "upper country"] in the context of the fur trade. 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 French name, Pays des Illinois, means "Land of the Illinois [plural]" and is a reference to the Illinois Confederation, a group of related Algonquian tribes (usually referred to as  "Illinois" or the "Illiniwek" or "Illini." who were a group of Indian tribes in the upper Mississippi River valley. The tribes were the Kaskaskia, Cahokia, Peoria, Tamaroa, Moingwena, Michigamea, Chepoussa, Chinkoa, Coiracoentanon, Espeminkia, Maroa, and Tapouara).

The Illinois Country's landscape of today's Illinois boundaries was a patchwork of prairies, forests, marshes, and swamps. Bison and elk roamed the upland prairies, bears and mountain lions prowled the forests and swamps, and the skies were often darkened by large flocks of pigeons. Bordering the land were three large streams: the Mississippi, Ohio, and Wabash rivers. One of the world's largest freshwater lakes, Lake Michigan, lies to the northeast. These and other aquatic and wetland environments teemed with many different species of waterfowl, fish, and freshwater mollusks.

Until 1717, the Illinois Country was governed by the French province of Canada, but by order of King Louis XV, the Illinois Country was annexed to the French province of Louisiana, with the northeastern administrative border somewhat vaguely on or near the upper Illinois River. The territory thus became known as "Upper Louisiana." By the mid-18th century, the major settlements included Cahokia, Kaskaskia, Chartres, Street  Philippe, and Prairie du Rocher, all on the east side of the Mississippi in present-day Illinois, and Ste. Genevieve across the river in Missouri and Fort Vincennes in what is now Indiana.

Due to the French defeat in the Seven Years' War (1756-1763), the Illinois Country east of the Mississippi River was ceded to the British and the land west of the river to the Spanish. Following the British occupation of the east shoreline of the Mississippi in 1764, some Canadian settlers remained in the area, while others crossed the river, forming new settlements such as St. Louis.

Eventually, the eastern part of the Illinois Country became part of the British Province of Quebec, while the inhabitants chose to side with the Americans during the Revolutionary War. 

Although the lands west of the Mississippi were sold in 1803 to the United States by France—which had reclaimed possession of Louisiana from the Spanish in the Third Treaty of San Ildefonso—French language and culture continued to exist in the area, with the Missouri French dialect still being spoken into the 20th century.

Because of the deforestation that resulted from cutting down forests for wood for fuel during the 19th-century age of steamboats, the Mississippi River became shallower and broader, causing severe Mississippi flooding between St. Louis and the confluence with the Ohio River. Consequently, many architectural and archaeological resources were lost to flooding and destruction of early French colonial villages near the river, including Kaskaskia and St. Philippe.

The Cahokia Mounds and the Indian Village of Cahokia.

The name Cahokia is a reference to one of the Indian tribes of the Illinois Confederation, a group of related Algonquian tribes (usually referred to as "Illinois" or the "Illiniwek" or "Illini," who were a group of Indian tribes in the upper Mississippi River valley. The tribes comprised the Kaskaskia, Cahokia, Peoria, Tamaroa, Moingwena, Michigamea, Chepoussa, Chinkoa, Coiracoentanon, Espeminkia, Maroa, and Tapouara) who were encountered by early French explorers to the region.

Early European settlers also named Cahokia Mounds after the Illinois Confederation, an extensive prehistoric Mississippian urban site located north of present-day Collinsville in Madison County. Cahokia Mounds is the site of a pre-Columbian Indian village directly across the Mississippi River from modern St. Louis, Missouri. This historic park lies between today's East St. Louis and Collinsville. The park covers 2,200 acres, or about 3.5 square miles, and contains about 80 mounds, but the ancient city was much larger. In its heyday, Cahokia covered about 6 square miles and included 120 manmade earthen mounds in various sizes, shapes, and functions.

Cahokia was the largest and most influential urban settlement of the Mississippian culture, which developed advanced societies across much of what is now the central and southeastern United States, beginning more than 1000 years before European contact. The city's original name has yet to be discovered.

The mounds were later named after the Cahokia tribe, a historic Illiniwek people living in the area when the first French explorers arrived in the 17th century. As this was centuries after Cahokia was abandoned by its original inhabitants, the Cahokia tribe was not necessarily descended from the earlier Mississippian-era people. Most likely, multiple indigenous ethnic groups settled in the Cahokia Mounds area during the time of the city's apex. It is a World Heritage Site and an Illinois State Historic Park.

The "New France" (hereinafter called Canada) association with Cahokia began over 320 years ago, with Father Pinet's mission in late 1696 to convert the Cahokia and Tamaroa Indians to Christianity. Father Pinet and the Seminary of Foreign Missions of Quebec built a log church, and it was dedicated to the Holy Family. During the next 100 years, Cahokia became one of the largest French colonial towns in the Illinois Country.

Cahokia had become the center of a large area for trading Indian goods and furs. The village had about 3,000 inhabitants, 24 brothels, and a thriving business district. The nearby town of Kaskaskia on the Mississippi became the region's leading shipping port, and Fort de Chartres became a military and governmental command center. The 50-mile area of land between the two cities was cultivated by farming settlers, known as habitants, whose main crop was wheat. As the site expanded, the relationship between the settlers and the Indians became peaceful. Settlers were mostly Canadien migrants whose families had been in North America for a while.

In the following years, Cahokia suffered, mainly from the French loss in the French and Indian War in 1763. Defeated by Great Britain in an extension of the Seven Years' War in Europe, the French were forced to cede large parts of the Illinois Country to the victors. Many Cahokians fled in fear of the British or because they wanted to live in a Catholic province, Louisiana, where they founded new Canadien villages west of the Mississippi River, such as St. Louis and Ste. Genevieve, Missouri.

The Odawa leader Pontiac was assassinated by other Indians in or near Cahokia on April 20, 1769. The Potawatomi blamed the local Illinois Indians and took revenge on them at Starved Rock by cornering them on the top of Starved Rock, waiting for their food and water to run out -- then killing all of them.

In 1778, during the American Revolutionary War, George Rogers Clark set up a court in Cahokia, making Cahokia an independent city-state even though it was part of the Province of Quebec. Cahokia officially became part of the United States by the Treaty of Paris in 1783. Soon after, the 105 Cahokia "heads of household" pledged loyalty to the Continental Congress of the United States.

In the 1800s, a Trappist Priest built a church on top of what they called "Monk's Mound." The New Madrid Earthquake of 1811-1812 was why this structure was vacated.
