, 1688 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.
Joseph de La Roche Daillon reached an
oil spring at the northeasternmost fringe of the Mississippi River basin during his 1627 missionary journey. In 1669–70, Father
Jacques Marquette, a missionary in French Canada, was at a mission station on
Lake Superior, when he met native traders from the
Illinois Confederation. He learned about the great river that ran through their country to the south and west. In 1673–74, with a commission from the Canadian government, Marquette and Louis Jolliet explored the
Mississippi River territory from
Green Bay to the
Arkansas River, including the
Illinois River valley. In 1675, Marquette returned to found a Jesuit mission at the
Grand Village of the Illinois. Over the next decades missions, trade posts, and forts were established in the region. By 1714, the principal European, non-native inhabitants were
Canadien fur traders,
missionaries and soldiers, dealing with Native Americans, particularly the group known as the
Kaskaskia. The main French settlements were established at
Kaskaskia,
Cahokia, and
Sainte Genevieve. By 1752, the population had risen to 2,573. From the 1710s to the 1730s, the
Fox Wars between the French, French allied tribes and the
Meskwaki people occurred in what is now northern Illinois, southern Wisconsin, and Michigan, in particular, over the fur trade. During the conflict, in what is now
McLean County, Illinois, French and allied forces won a consequential battle against the Meskwaki in 1730.
Fort St. Louis du Rocher French explorers led by
René-Robert Cavelier, Sieur de La Salle built Fort St. Louis on a large
butte by the Illinois River in the winter of 1682. Called
Le Rocher, the butte provided an advantageous position for the fort above the river. By orders of the governor, traders and his officer were escorted to Illinois. After the port of
New Orleans, along the Mississippi River to the south, was founded in 1718, more African slaves were imported to the Illinois Country for use as agricultural and mining laborers. By the mid-eighteenth century, slaves accounted for as much as a third of the population.
Other settlements • In 1675,
Jacques Marquette founded the mission of the Immaculate Conception of the Blessed Virgin at the
Grand Village of the Illinois, near present-day
Utica, Illinois, which was destroyed by
Iroquois in 1680. French interests dominated at Peoria for well over a hundred years, from the time the first French explorers came up the Illinois River in 1673 until the first United States settlers began to move into the area around 1815. A small French presence persisted for a time on the east bank of the river, but was gone by about 1846. Today, only faint echoes of French Peoria survive in the street plan of downtown Peoria, and in the name of an occasional street, school, or hotel meeting room:
Joliet,
Marquette,
LaSalle. • The
Mission of the Guardian Angel was established near the
Chicago portage between 1696 and 1700. in Cahokia •
Cahokia, established in 1696 by French missionaries from
Quebec, was one of the earliest permanent settlements in the region. It became one of the most populous of the northern towns. In 1787, it was made the seat of St. Clair County in the
Northwest Territory. In 1801,
William Henry Harrison, then governor of
Indiana Territory, enlarged St. Clair County to administer a vast area extending to the Canada–US border. By 1814, the county had been reduced to almost the size of present-day
St. Clair County, Illinois. The county seat was shifted from Cahokia to
Belleville. On April 20, 1769, the great Indian leader
Chief Pontiac was murdered in Cahokia by a chief of the
Peoria. •
Kaskaskia, established in 1703, was at first small mission station for the French. It flourished to become capital of the
Illinois Territory, 1809–1818, and the first capital of the state of Illinois, 1818−1820. The French built a fort here in 1721, which was destroyed in 1763 by the British. (The fort was situated above what was then the lower course of the
Kaskaskia River, but became the new channel of the Mississippi in 1881.) During the
American Revolutionary War, General
George Rogers Clark took possession of the village in 1778. The residents rang the church bell in celebration, and it became known as the "liberty bell". (It had been sent in 1741 by King
Louis XV.) Flooding and a lateral shift of the river channel in 1881 cut off the old settlement from the mainland of Illinois and destroyed some of the village and its archaeology. Much of the village cemetery was transferred to the higher ground of
Fort Kaskaskia State Park across the river. Today visitors can reach the remnants of Kaskaskia only by a bridge and road from the Missouri side. In the
Great Flood of 1993, the Mississippi submerged all but a few rooftops and the steeple of the
Catholic Church of the
Immaculate Conception, built in 1843 and moved brick by brick to the new location on Kaskaskia Island about 1893. • In 1720,
Philip Francois Renault, the Director of Mining Operations for the Company of the West, arrived with about 200 laborers and mechanics and 500 African
slaves from
Saint-Domingue to work
the mines. However, the mines yielded only unprofitable
coal and
lead, providing insufficient revenues for the Company of the West to survive. In 1723, Renault, with his workers and slaves, established the village of St. Philippe (on the
Bottoms down from the present-day unincorporated community of
Renault, Illinois in
Monroe County, Illinois.) It was about 3 miles north of Fort de Chartres. This is the first record of
African slaves in the region. Some of the French farmers also used slaves for labor, but most families held only a few, if any. The village quickly produced an agricultural surplus, with its goods sold to lower Louisiana, as well as to settlements less successful than those in the Illinois Country, such as Arkansas Post. • As early as 1733, a trading post was established by Jean Baptiste de Girardot at
Cape Girardeau and the town later formed in 1793. • The original
Ste. Genevieve was established around 1750 along the western banks of the
Mississippi River. The village consisted of mostly farmers and merchants of
French-Canadian descent from the settlements on the east side. Despite flooding, the town remained in that location until the great flood of 1785 destroyed much property. The villagers decided to move the entire village to higher ground about two miles north and half a mile back from the river floodplain. The city has retained the most buildings of
French Colonial architecture in the US. • The French established
Fort Orleans in 1723 along the
Missouri River near
Brunswick, Missouri. •
Fort Vincennes, on the Wabash River, later known as
St. Vincennes and eventually
Vincennes, Indiana, was established in 1732. The British renamed it
Fort Sackville after their capture of it in the
French and Indian War (also known as the
Seven Years' War.) George Rogers Clark renamed it Fort
Patrick Henry, for the Governor of Virginia, when he took it in the
American Revolution. Although part of the original expansive Illinois Country, as part of the Northwest Territory, it became the seat of a separate county. • The French built
Fort de L'Ascension (later, de Massiac) on the
Ohio River in 1757 near present-day
Metropolis, Illinois. •
St. Louis was founded in 1764 by French fur traders. In 1765, it was made the
capital of Upper Louisiana; and after 1767, control of the region west of the Mississippi was given to the Spanish ("District of Illinois" ==British province of Quebec==
