| The influence of physical geography upon political development. |
The element of physical geography always plays a large part in national political development. The natural territorial basis of a national state is a geographical unity. That is, it is a territory separated by broad bodies of water, or high mountain ranges, or broad belts of uninhabitable country, or climatic extremes, from other territory, and possessing a fair degree of coherence within. If a national state develops itself on any part of such a territory, it will inevitably tend to spread to the natural limits of the same. It will not become a completely national state until it shall have attained such boundaries, for a completely national state is the sovereign organization of a people having an ethnic unity upon a territory which is a geographic unity.
| Defect in the southern boundary of the United States before 1819. |
In the second decade of this century, and down to the latter part of it, the United States had not acquired the territory of the country as far as to the natural southern boundary east of Louisiana. This boundary was, of course, the Gulf of Mexico; but Spain held in quasi possession a broad strip, and then a long peninsula, of land along and within this boundary. In other words, the territory called Florida, or the Floridas, was, politically, a colony of Spain, but geographically a part of the United States. It was inhabited chiefly by Indian tribes. Spanish rule in this territory was, therefore, foreign rule, both from the geographical point of view and the ethnical. Indian rule was not to be thought of in the nineteenth century. There was but one natural solution of the question. It was that the United States should annex this territory and extend the jurisdiction of the general Government over it.
| The Treaty of Paris of 1763. |
The Treaty of Paris of 1763 was the first great international agreement which gave a fair degree of definiteness to the claims of England, France, and Spain, upon the North American continent. In this Treaty, France surrendered Canada, Cape Breton, and all claims to territory east of the Mississippi River, from the source of the river to the point of confluence of the Iberville with it, to Great Britain. From this latter point, the boundary between the two powers was declared to be the middle line of the Iberville, and of the Lakes Maurepas and Pontchartrain, to the Gulf of Mexico. It is also expressly stated in this Treaty that France cedes the river and port of Mobile to Great Britain.
In this same instrument, Spain surrendered to Great Britain Florida and every claim to territory east and southeast of the Mississippi.
