When England began to contend with France and Spain for the possession of North America, she made royal grants of land upon this continent, in royal ignorance of its extent and configuration. But until the Seven Years' War the eastward and westward partitioning of these grants was of little practical consequence; for English dominion was bounded by the Alleghanies, and everything beyond was in the hands of the French. In that most momentous war the genius of the elder Pitt won the region east of the Mississippi for men of English race, while the vast territory of Louisiana, beyond, passed under the control of Spain. During the Revolutionary War, in a series of romantic expeditions, the state of Virginia took military possession of a great part of the wilderness east of the Mississippi, founding towns in the Ohio and Cumberland valleys, and occupying with garrisons of her state militia the posts at Cahokia, Kaskaskia, and Vincennes. We have seen how, through the skill of our commissioners at Paris, this noble country was secured for the Americans in the treaty of 1783, in spite of the reluctance of France and the hostility of Spain. Throughout the Revolutionary War the Americans claimed the territory as part of the United States; but when once it passed from under the control of Great Britain, into whose hands did it go? To whom did it belong? To this question there were various and conflicting answers. North Carolina, indeed, had already taken possession of what was afterward called Tennessee, and at the beginning of the war Virginia had annexed Kentucky. As to these points there could be little or no dispute. But with the territory north of the Ohio River it was very different. Four states laid claim either to the whole or to parts of this territory, and these claims were not simply conflicting, but irreconcilable. [Sidenote: Claims of Massachusetts and Connecticut.]
