UPON the earth, with its varied configuration and formation of land and sea, are many kinds of hindrances and limits to life.
The most obvious effect of natural region and natural boundary lies in the counteracting forces opposed by the earth through them to a formless and unlimited diffusion of life. Isolated territory furthers political independence, which, indeed, is of itself isolation. The development of a nation upon a fixed territory consists in a striving to make use of all the natural advantages of that territory. The superiority of a naturally isolated region lies in the fact that seclusion itself brings with it the greatest of all advantages. Hence the precocious economic and political development of races that dwell on islands or on peninsulas, in mountain valleys and on island-like deltas.
The Rise and Death of Isolated States
Often enough growth that originates under such favourable conditions leads to ruin. A young nation deems itself possessed of all so long as it has the isolation that ensures independence; it sees too late that the latter has been purchased at the price of a suffocating lack of space; and it dies of a hypertrophy of development—a death common to minor states. This was the cause of the swift rise and decline of Athens and of Venice, and of all powers that restricted themselves to islands and to narrow strips of coast.
Natural Boundaries of a State
The more natural boundaries a state possesses, the more definite are the political questions raised by its development. The consolidation of England, Scotland, and Wales was simple and obvious, as patent as if it had been decreed beforehand, as was also the expansion of France over the region that lies between the Alps and the Pyrenees, the Mediterranean and the Atlantic Ocean. On the other hand, what a fumbling, groping development was that of Germany, with her lack of natural boundary in the east! Thus in the great geographical features of lands lie pre-ordained movements, constrained by the highest necessity—a higher necessity in the case of some than of others. The frontier of the Pyrenees was more necessary to France than that of the Rhine; an advance to the Indian Ocean is more necessary to Russia than a movement into Central Europe. Growth is soundest when a state expands so as to fill out a naturally bounded region—as, for example, the United States, that symmetrically occupy the southern half of the continent of North America, or Switzerland, extending to the Rhine and Lake of Constance. There are often adjustments of frontiers which force the territory of a nation back into a natural region, as shown in the case of Chili, which gave up the attempt to extend its boundaries beyond the Andes, in spite of its having authorisation to do so, founded on the right of discovery, the original Spanish division of provinces, and wars of independence. A favourable external form is often coincident with a favourable internal configuration which is quite as furthering to internal continuity as is the external form to isolated development. The Roman Empire, externally uniform as an empire of Mediterranean states, was particularly qualified for holding fast to its most distant provinces, by reason of the Mediterranean Sea that occupied its very centre. Everything that furthers traffic is also favourable to cohesion. Hence the significance of waterways for ancient states, and of canals and railways for modern nations. Egypt was the empire of the Nile, and the Rhine was at one time the life-vein of the empire of Charles the Great. A state does not always remain fixed in the same natural region. However advantageous they may have been, it must, on increasing, forsake the best of boundaries. Since one region is exchanged for another, the law of increasing areas comes into force. Every land, sea, river region, or valley should always be conceived of as an area that must be discovered, inhabited, and politically realised before it may exert any influence beyond its limits. Thus the Mediterranean district had first to complete its internal development before it could produce any external effect.
First Continent State
This internal development first took possession of the small territories, and, mastering them, turned to the greater. Thus we may see history progress from clearings in forests, oases, islands, small peninsulas, such as Greece; and strips of coast, to great peninsulas, such as Italy; isthmian situations of continental size, such as Gaul; only to come to a halt in half continents such as the United States and Canada, and continents. Europe—next to the smallest continent—has had the richest history of all, but with the greatest breaking up of its area into small divisions. Australia, the smallest continent, is the earliest to unite its parts into a continental state. Development expends all its power in bringing the areas of the three greatest land-divisions into play, and in opposing their one hundred and five million square miles to the ten and a half million of the smaller divisions; their economic action is already felt to a considerable degree. Thus there arises an alternation of isolation and expansion, which was clearly shown in the history of Rome, whose territory grew from the single city, out over the valley of the Tiber, into Apennine Italy, into the peninsula, across the islands and peninsulas of the Mediterranean, and finally into the two adjacent continents.
