The Illinois Country was governed by military commandants for its entire period under French and British rule, and during its time as a county of Virginia. The presence of French military interests in the Illinois Country began in 1682 when Robert de La Salle built Fort St. Louis du Roche on the Illinois River. The commandant of the fort was the top French official in the region and was responsible to the Governor General of New France. In 1718 Illinois was transferred to Louisiana and renamed Upper Louisiana. The new seat of government was Fort de Chartres, located in what is now southeastern Illinois among the growing French settlements of Cahokia, Kaskaskia and Prairie du Rocher.
In 1763, at the conclusion of the French and Indian War, the entire area of Louisiana was divided, with Great Britain receiving the lands east of the Mississippi and Spain claiming the lands west of it. The new city of St. Louis, in present-day Missouri, became the seat of government of Spanish Upper Louisiana. The government of the British side, present-day Illinois, remained in the hands of military commandants at Fort de Chartres; upon that fort's abandonment the seat of government moved to Kaskaskia. British rule in Illinois was ad hoc and unsystematic. The Quebec Act of 1774 would have organized a government for the region, but before it could be put into effect Illinois was captured by Virginia militia in the Illinois Campaign. [1]
After 1787 Illinois received a civil government as part of the Northwest and Indiana Territories before becoming a distinct Illinois Territory in 1809. The United States acquired the rest of Upper Louisiana in the Louisiana Purchase of 1803; military rule continued for a few months before it was transferred to civilian government, first under the Indiana Territory, and then as the Louisiana Territory in 1805.
This period included the entire Mississippi River and Missouri River basin above the mouth of the Arkansas River.
After the Seven Years' War ended in 1763, the Treaty of Paris awarded Great Britain the east bank of the Mississippi, from below Baton Rouge northwards. Due to the outbreak of Pontiac's War, British forces were unable to take control of the Illinois forts until 1765. [2]
Virginia militia under George Rogers Clark captured Illinois in the Illinois Campaign of 1778. The territory was organized as Illinois County, Virginia and placed under a military government, which was intended to be temporary. This government came to an end in 1784, when Virginia ceded the Illinois Country to the United States government. It became part of the Northwest Territory in 1787. [3]
After 1765, when Western Louisiana was ceded to Spain by France, the provincial capitol of Upper Louisiana was St. Louis. In spite of that, the governors of Saint Louis maintained the name of "commandants of Illinois". During this period, Upper Louisiana referred only to the land west of the Mississippi River and above the mouth of the Arkansas River.
In 1803, France under Napoleon purchased Louisiana from Spain. France never established its rule in Upper Louisiana, and already in 1803 it sold the entire territory to the United States as the Louisiana Purchase. Jurisdiction was above the 33rd parallel on the west side of the Mississippi River. Nominal French control at St. Louis lasted only a single day, known as Three Flags Day, when sovereignty was symbolically transferred from Spain to France to the United States. American military rule continued for a few months. On October 1, 1804, civilian government began under the Governor of Indiana Territory. Upper Louisiana was reorganized as the Louisiana Territory in 1805 and the Missouri Territory in 1812.
Kaskaskia is a village in Randolph County, Illinois. Having been inhabited by indigenous peoples, it was settled by France as part of the Illinois Country. It was named for the Kaskaskia people. Its population peaked at about 7,000 in the 18th century, when it was a regional center. During the American Revolutionary War, the town, which by then had become an administrative center for the British Province of Quebec, was taken by the Virginia militia during the Illinois campaign. It was designated as the county seat of Illinois County, Virginia, after which it became part of the Northwest Territory in 1787. Kaskaskia was later named as the capital of the United States' Illinois Territory, created on February 3, 1809. In 1818, when Illinois became the 21st U.S. state, the town briefly served as the state's first capital until 1819, when the capital was moved to more centrally located Vandalia.
Prairie du Rocher is a village in Randolph County, Illinois, United States. Founded in the French colonial period in the American Midwest, the community is located near bluffs that flank the east side of the Mississippi River along the floodplain often called the "American Bottom". The population was 502 at the 2020 census.
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 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 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.
Fort de Chartres was a French fortification first built in 1720 on the east bank of the Mississippi River in present-day Illinois. It was used as the administrative center for the province, which was part of New France. Due generally to river floods, the fort was rebuilt twice, the last time in limestone in the 1750s in the era of French colonial control over Louisiana and the Illinois Country.
Louisiana or French Louisiana was an administrative district of New France. In 1682 the French explorer René-Robert Cavelier, Sieur de la Salle erected a cross near the mouth of the Mississippi River and claimed the whole of the drainage basin of the Mississippi River in the name of King Louis XIV, naming it "Louisiana". This land area stretched from the Great Lakes to the Gulf of Mexico and from the Appalachian Mountains to the Rocky Mountains. The area was under French control from 1682 to 1762 and in part from 1801 (nominally) to 1803.
Pierre Dugué de Boisbriand was a French Canadian soldier, politician, and aristocrat who commanded several areas in North America colonized by New France in the early 18th Century and who served as the seventh governor of the French colony of Louisiana.

Philippe-François de Rastel de Rocheblave also, known as, Philippe de Rocheblave and the Chevalier de Rocheblave, was a soldier and businessman in the Illinois Country, of Upper Louisiana, and later, a political figure in Lower Canada. He was sometimes referred to as the Chevalier de Rocheblave.
Louisiana, or the Province of Louisiana, was a province of New Spain from 1762 to 1801 primarily located in the center of North America encompassing the western basin of the Mississippi River plus New Orleans. The area had originally been claimed and controlled by France, which had named it La Louisiane in honor of King Louis XIV in 1682. Spain secretly acquired the territory from France near the end of the Seven Years' War by the terms of the Treaty of Fontainebleau (1762). The actual transfer of authority was a slow process, and after Spain finally attempted to fully replace French authorities in New Orleans in 1767, French residents staged an uprising which the new Spanish colonial governor did not suppress until 1769. Spain also took possession of the trading post of St. Louis and all of Upper Louisiana in the late 1760s, though there was little Spanish presence in the wide expanses of what they called the "Illinois Country".
"Indian Reserve" is a historical term for the largely uncolonized land in North America that was claimed by France, ceded to Great Britain through the Treaty of Paris (1763) at the end of the Seven Years' War—also known as the French and Indian War—and set aside for the First Nations in the Royal Proclamation of 1763. The British government had contemplated establishing an Indian barrier state in a portion of the reserve west of the Appalachian Mountains, bounded by the Ohio and Mississippi rivers and the Great Lakes. British officials aspired to establish such a state even after the region was assigned to the United States in the Treaty of Paris (1783) ending the American Revolutionary War, but abandoned their efforts in 1814 after losing military control of the region during the War of 1812.
