Vincenzo Coronelli labeled the region (in Italian) as ''Illinois country.'' In 1721, the seventh military district of Louisiana was named ''Illinois''. It included more than half of the present state, as well as the land between the

A generation later, trade conflicts between Canada and Louisiana led to a more defined boundary between the French colonies; in 1745, Louisiana governor general

This boundary between Canada and the Illinois Country remained in effect until the
Treaty of Paris in 1763, after which France surrendered its remaining territory east of the Mississippi to Great Britain.

Distinctions became somewhat clearer after the
Treaty of Paris in 1763, when Britain acquired Canada and the land claimed by France east of the Mississippi and Spain acquired Louisiana west of the Mississippi. Many French settlers moved west across the river to escape British control.
On the west bank, the Spanish also continued to refer to the western region governed from
St. Louis as the ''District of Illinois'' and referred to St. Louis as the ''city of Illinois''.
Exploration and settlement
The first French explorations of the Illinois Country were in the first half of the 17th century, led by explorers and missionaries based in Canada.
Étienne Brûlé explored the upper Illinois country in 1615 but did not document his experiences.

was the only form of defenses that La Salle used in securing the site. Inside the fort were a few wooden houses and native shelters. The French intended St. Louis to be the first of several forts to defend against English incursions and keep their settlements confined to the East Coast.

After La Salle's five-year monopoly ended New France governor Joseph-Antoine de La Barre wished to put Fort Saint Louis along with Fort Frontenac under his jurisdiction. By orders of the governor, traders and his officer were escorted to Illinois. On August 11, 1683, LaSalle's armorer, Pierre Prudhomme, obtained approximately one and three-quarters of a mile of the north portage shore.

Fort de Chartres
On January 1, 1718, a trade monopoly was granted to John Law's Company. Hoping to make a fortune mining precious metals in the area, the company with a military contingent sent from New Orleans built a fort to protect its interests. Construction began on the first Fort de Chartres (in present-day Illinois) in 1718 and was completed in 1720.
The original fort was located on the east bank of the Mississippi River, downriver (south) from Cahokia and upriver of Kaskaskia. The nearby settlement of Prairie du Rocher, Illinois, was founded by French-Canadian colonists in 1722, a few miles inland from the fort.
The fort was to be the seat of government for the Illinois Country and help to control the aggressive Meskwaki. The fort was named after Louis, duc de Chartres, son of the regent of France. Because of frequent flooding, another fort was built further inland in 1725. By 1731, the Company of the Indies had gone defunct and turned Louisiana and its government back to the king. The garrison at the fort was removed to Kaskaskia, Illinois in 1747, about 18 miles to the south. A new stone fort was planned near the old fort and was described as "nearly complete" in 1754, although construction continued until 1760.
The new stone fort was headquarters for the French Illinois Country for less than 20 years, as it was turned over to the British in 1763 with the Treaty of Paris at the end of the French and Indian War

Agricultural settlement and slavery
According to historian Carl J. Ekberg, the French settlement pattern in Illinois Country was generally unique in 17th- and 18th-century French North America. These were unlike other such French settlements, which primarily had been organized in separated homesteads along a river with long rectangular plots stretching back from the river (ribbon plots). The Illinois Country French, although they marked long-ribbon plots, did not reside on them. Instead, settlers resided together in farming villages, more like the farming villages of northern France, and practiced communal agriculture.[Ekberg (2000), pp. 28−32]

A small French presence persisted for a time on the east bank of the river, but was gone by about 1846.

Some of the French farmers also used slaves for labor, but most families held only a few, if any.
