Shortly after, several forts were built within the present limits of Illinois, of which fort Chartres was the most considerable. By these means a chain of communication was formed from Canada to the mouth of the Mississippi.

In 1699, M. Ibberville arrived in the gulf of Mexico with two frigates, and in March ascended the river in a felucca one hundred leagues, and returned by the bayou or outlet that bears his name, through lake Ponchartrain to the gulf. He planted his colony at Biloxi, a healthy but sterile spot between the Mobile and Mississippi rivers, and built a fortification. During several succeeding years much exploring was done, and considerable trade carried on with the Indians for peltries, yet these expeditions were a source of much expense to France.

In January, 1702, the colony at Mobile was planted; several other settlements were soon after formed. The Catholics also commenced several missions amongst the Indians. Difficulties frequently occurred with their Spanish neighbors in Florida and Mexico.

M. Ibberville died in 1706, and M. Bienville succeeded him in the government of Louisiana for many years. The city of New Orleans was founded, during his administration, in 1719. It is situated on the east bank of the Mississippi, one hundred and five miles from its mouth. From 1723 to 1730, the French had exterminating wars with the Natchez, a powerful nation of Indians. They had killed 700 French in 1723, and about 1730 the French exterminated the nation. Various wars took place subsequently with the Spanish and English. But over most of the Indians along the Mississippi, these French colonists gained extraordinary influence.—During this period emigrants continued to arrive from France, so that the colonists rapidly increased in numbers.

The Mississippi land scheme, or "bubble" as it was called, originated with the celebrated John Law in 1717, which soon burst and spread ruin throughout the monied interests of France. The amount of stock created, was said to equal 310,000,000 of dollars. The whole proved an entire failure, but it served to increase greatly the population of Louisiana, so that from 1736, the colonies in the Lower Valley prospered.

In 1754, the war commenced between France and England relative to the boundaries of the Canadas. At that period France claimed all the countries west of the Alleghany mountains, while England on the other hand had granted to Virginia, Connecticut and other colonies, charters which extended across the continent to the "South Sea," as the Pacific ocean was then called. A grant also was made by Virginia, and the crown of Great Britain, of 600,000 acres to a company called "The Ohio Company." The governor of New France, as Canada and Louisiana was then called, protested, erected forts on lake Erie, and at the present site of Pittsburg, and enlisted the Indians against the English and Americans. Pittsburg was then called Fort du Quesne. Then followed Braddock's war, as this contest is called in the west,—the mission of Major (afterward General) Washington,—the defeat of Braddock; and finally by the memorable victory of Wolfe at Quebec, and the lesser ones at Niagara and Ticonderoga, and by victories of the English fleet on the ocean, the French were humbled, and at the treaty of Paris, in 1763, surrendered all their claims to the country east of the Mississippi. Towards the close of the war, however, France, by a secret treaty, ceded all the country west of the Mississippi, and including New Orleans, to Spain, who held possession till 1803, when it was delivered to the French government under Napoleon, and by him ceded to the United States for 15,000,000 of dollars.

The English held possession of the military posts, and exercised jurisdiction over the country of Illinois, and the adjacent regions, till 1778, during the revolutionary war; when by a secret expedition, without direct legislative sanction, but by a most enterprising, skilful, and hazardous military manœuvre, the posts of Kaskaskia, Cahokia, Fort Chartres and Vincennes were captured by Gen. George Rogers Clark, with a small force of volunteer Americans, and that portion of the Valley fell under the jurisdiction of Virginia.

The legislature of Virginia sanctioned the expedition of Clark, which the Executive, Patrick Henry and his council, with Thomas Jefferson, George Wythe, and George Mason, by written instructions, had agreed should be done, and a county called "Illinois" was organized the same year.

In 1784, Virginia, in conjunction with other states, ceded all claims to the Great West, to the United States, reserving certain tracts for the payment of revolutionary claims. This cession laid the foundation for five new states northwest of Ohio, when each district should have 60,000 inhabitants, and even a less number, by consent of Congress. Two restrictions were peremptorily enjoined,—that each state should adopt a constitution with a republican form of government, and that slavery or involuntary servitude, should be forever prohibited.

It is unnecessary here to enter into details of the settlement of each particular state,—the incessant attacks from the Indians,—the border wars that ensued,—the adventures of Boone and his associates in settling Kentucky,—the unfortunate campaigns of Harmar and St. Clair,—the victorious one of Wayne,—or the reminiscences and events of the war of 1812, and its termination in 1815. Some historical notices of each state may be found in their proper place.
