Province of Quebec (1763–1791) in the context of "Old Northwest"

Quebec (French: Québec) is Canada's largest province by area. Located in Central Canada, the province shares borders with the provinces of Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast and a coastal border with the territory of Nunavut. In the south, it shares a border with the United States. Quebec has a population of around 8 million, making it Canada's second-most populous province only behind Ontario.

Between 1534 and 1763, what is now Quebec was the French colony of Canada and was the most developed colony in New France. Following the Seven Years' War, Canada became a British colony, first as the Province of Quebec (1763–1791), then Lower Canada (1791–1841), and lastly part of the Province of Canada (1841–1867) as a result of the Lower Canada Rebellion. It was confederated with Ontario, Nova Scotia, and New Brunswick in 1867. Until the early 1960s, the Catholic Church played a large role in the social and cultural institutions in Quebec. However, the Quiet Revolution of the 1960s to 1980s increased the role of the Government of Quebec in l'État québécois (the public authority of Quebec).

United Empire Loyalist (UEL; or simply Loyalist) is an honorific title which was first given by the 1st Lord Dorchester, the governor of Quebec and governor general of the Canadas, to American Loyalists who resettled in British North America during or after the American Revolution. At that time, the demonym Canadian or Canadien was used by the descendants of New France settlers inhabiting the Province of Quebec.

They settled primarily in Nova Scotia and the Province of Quebec. The influx of loyalist settlers resulted in the creation of several new colonies. In 1784, New Brunswick was partitioned from the Colony of Nova Scotia after significant loyalist resettlement around the Bay of Fundy. The influx of loyalist refugees also resulted in the Province of Quebec's division into Lower Canada (present-day Quebec), and Upper Canada (present-day Ontario) in 1791. The Crown gave them land grants of one lot. One lot consisted of 200 acres (81 ha) per person to encourage their resettlement, as the Government wanted to develop the frontier of Upper Canada. This resettlement added many English speakers to the Canadian population. It was the beginning of new waves of immigration that established a predominantly Anglo-Canadian population in the future Canada both west and east of the modern Quebec border.

The Province of Upper Canada (French: province du Haut-Canada) was a part of British Canada established in 1791 by the Kingdom of Great Britain, to govern the central third of the lands in British North America, formerly part of the Province of Quebec since 1763. Upper Canada included all of modern-day Southern Ontario and all those areas of Northern Ontario in the Pays d'en Haut which had formed part of New France, essentially the watersheds of the Ottawa River or Lakes Huron and Superior, excluding any lands within the watershed of Hudson Bay. The "upper" prefix in the name reflects its geographic position along the Great Lakes, mostly above the headwaters of the Saint Lawrence River, contrasted with Lower Canada (present-day Quebec) to the northeast.

Upper Canada was the primary destination of Loyalist refugees and settlers from the United States after the American Revolution, who often were granted land to settle in Upper Canada. Already populated by Indigenous peoples, land for settlement in Upper Canada was made by treaties between the new British government and the Indigenous peoples, exchanging land for one-time payments or annuities. The new province was characterized by its British way of life, including bicameral parliament and separate civil and criminal law, rather than mixed as in Lower Canada or elsewhere in the British Empire. The division was created to ensure the exercise of the same rights and privileges enjoyed by loyal subjects elsewhere in the North American colonies. In 1812, war broke out between Great Britain and the United States, leading to several battles in Upper Canada. The United States attempted to capture Upper Canada, but the war ended with the situation unchanged.

Canada was a French colony within New France. It was claimed by France in 1534 during the first voyage of Jacques Cartier in the name of the French king, Francis I. The colony remained a French territory until 1763, when it became a British colony known as the Province of Quebec at the end of the global Seven Years' War.

In the 16th century the word Canada could refer to the territory along the Saint Lawrence River (then known as the Canada River) from Grosse Isle to a point between Québec and Trois-Rivières. The terms "Canada" and "New France" were also used interchangeably. French explorations continued west "unto the Countreys of Canada, Hochelaga, and Saguenay" before any permanent settlements were established. In 1600 a permanent trading post and habitation was established at Tadoussac at the confluence of the Saguenay and Saint Lawrence rivers. However, because this trading post was under a trade monopoly, it was not constituted as an official French colonial settlement.

The Vermont Republic, officially known at the time as the State of Vermont, was an independent state in New England that existed from January 15, 1777, to March 4, 1791. The state was founded in January 1777, when delegates from 28 towns met and declared independence from the jurisdictions and land claims of the British colonies of Quebec, New Hampshire, and New York. The republic remained in existence for the next fourteen years, albeit without diplomatic recognition from any foreign power. On March 4, 1791, it was admitted into the United States as the State of Vermont, with the constitution and laws of the independent state continuing in effect after admission.

The delegates forbade adult slavery within their republic, although the Vermont constitution continued to make allowances for the enslavement of men under the age of 21 and women under the age of 18. Many Vermonters took part in the American Revolution on the side of the Revolution, but the Continental Congress did not recognize the independence of Vermont (then also known as the New Hampshire Grants) due to objections from New York, which had conflicting property claims. In a response to this, members representing Vermont conducted negotiations to join the Province of Quebec, which were accepted by the British, who offered generous terms for the republic's reunion. When the British surrendered at the Siege of Yorktown in 1781, however, American independence became apparent. Vermont, later bordered on three sides by U.S. territory, ended negotiations with Britain and instead negotiated terms to become part of the United States.

The Illinois campaign, also known as Clark's Northwestern campaign, was a series of engagements during the American Revolutionary War in which a small force of Virginia militia led by George Rogers Clark seized control of several British outposts in the region northwest of the Ohio River in what is now Illinois and Indiana. The campaign is the best-known action of the western theater of the war and the source of Clark's reputation as an early American military hero.

In July 1778, Clark and his men descended the Ohio River from the Falls of the Ohio, crossed overland to the Mississippi River and took control of Kaskaskia, Cahokia, and several other villages in British territory. Vincennes, on the Wabash River was occupied a few weeks later. The occupation was accomplished without firing a shot because many of the French-speaking inhabitants of the region were sympathetic to the Patriot cause. To counter Clark's advance, Henry Hamilton, the British lieutenant-governor based at Fort Detroit, reoccupied Vincennes with a small force in December 1778. In February 1779, Clark returned to Vincennes in a surprise winter expedition and retook the town, capturing Hamilton in the process. Virginia capitalized on Clark's success by establishing the region as Illinois County.The importance of the Illinois campaign has been the subject of much debate. Because the British ceded the entire area northwest of the Ohio River to the United States in the 1783 Treaty of Paris, some historians have credited Clark actions with nearly doubling the size of the original Thirteen Colonies. For this reason, Clark was acclaimed "Conqueror of the Northwest", and his Illinois campaign—particularly his surprise march on Vincennes—was greatly celebrated and romanticized.

The Northwest Territory, also known as the Old Northwest and formally known as the Territory Northwest of the River Ohio, was formed from part of the unorganized western territory of the United States after the American Revolution. Established in 1787 by the Congress of the Confederation through the Northwest Ordinance, it was the nation's first post-colonial organized incorporated territory.

At the time of its creation, the territory included all the land west of Pennsylvania, northwest of the Ohio River and east of the Mississippi River below the Great Lakes, and what later became known as the Boundary Waters. The region was ceded to the United States in the Treaty of Paris of 1783. Throughout the Revolutionary War, the region was part of the British Province of Quebec and the western theater of the war. It spanned all or large parts of six eventual U.S. states (Ohio, Indiana, Illinois, Michigan, Wisconsin, and the northeastern part of Minnesota). Reduced to present-day Ohio, and some additional lands north and east on July 4, 1800, it ceased to exist March 1, 1803, when the southeastern portion of the territory was admitted to the Union as the state of Ohio, and the remainder attached to Indiana Territory.

The Pays d'en Haut (French: [pɛ.i dɑ̃ o]; Upper Country) was a territory of New France covering the regions of North America located west of Montreal. The vast territory included most of the Great Lakes region, expanding west and south over time into the North American continent as the French had explored. The Pays d'en Haut was established in 1610 and depended on the colony of Canada until 1763, when the Treaty of Paris ended New France, and both were ceded to the British as the Province of Quebec.
