Small geographic base of primitive societies.
Growth has been the law of human societies since the birth of man's gregarious instinct. It has manifested itself in the formation of ever larger social groups, appropriating ever larger areas. It has registered itself geographically in the protrusion of ethnic boundaries, economically in more intensive utilization of the land, socially in increasing density of population, and politically in the formation of ever larger national territorial aggregates. The lowest stages of culture reveal small tribes, growing very slowly or at times not at all, disseminated over areas small in themselves but large for the number of their inhabitants, hence sparsely populated. The size of these primitive holdings depends upon the natural food supply yielded by the region. They assume wide dimensions but support groups of only a few families on the chill rocky coasts of Tierra del Fuego or the sterile plains of central Australia; and they contract to smaller areas dotted with fairly populous villages in the fertile districts of the middle Congo or bordering the rich coast fishing grounds of southern Alaska and British Columbia. But always land is abundant, and is drawn upon in widening circles when the food supply becomes inadequate or precarious.
Influence of small confined areas.
Where nature presents barriers to far-ranging food-quests, man is forced to advance from the natural to the artificial basis of subsistence; he leaves the chase for the sedentary life of agriculture. Extensive activities are replaced by intensive ones, wide dispersal of tribal energies by concentration. The extensive forests and grassy plains of the Americas supported abundant animal life and therefore afforded conditions for the long survival of the hunting tribes; nature put no pressure upon man to coerce him to progress, except in the small mountain-walled valleys of Peru and Mexico, and in the restricted districts of isthmian Central America. Here game was soon exhausted. Agriculture became an increasing source of subsistence and was forced by limited area out of its migratory or essartage stage of development into the sedentary. As fields become fixed in such enclosed areas, so do the cultivators. Here first population becomes relatively dense, and thereby necessitates more elaborate social and political organization in order to prevent inner friction.
The geographically enclosed district has the further advantage that its inhabitants soon come to know it out to its boundaries, understand its possibilities, exploit to the utmost its resources, and because of the closeness of their relationship to it and to each other come to develop a conscious national spirit. The population, since it cannot easily spread beyond the nature-set limits, increases in density. The members of the compact society react constantly upon one another and exchange the elements of civilization. Thus the small territory is characterized by the early maturity of a highly individualized civilization, which then, with inherent power of expansion, proceeds to overleap its narrow borders and conquer for itself a wide sphere of influence. Hand in hand with this process goes political concentration, which aids the subsequent expansion. Therefore islands, oases, slender coastal strips and mountain valleys repeatedly show us small peoples who, in their seclusion, have developed a tribal or national consciousness akin in its intensity to clan feeling. This national feeling is conspicuous in the English, Japanese, Swiss and Dutch, as it was in the ancient city-states of Greece. The accompanying civilization, once brought to maturity in its narrow breeding place, spreads under favorable geographic conditions over a much larger space, which the accumulated race energy takes for its field of activity. The flower which thus early blooms may soon fade and decay; nevertheless the geographically evolved national consciousness persists and retains a certain power of renewal. This has been demonstrated in the Italians and modern Greeks, in the Danes and the Icelanders. In the Jews it has resisted exile from their native land, complete political dissolution, and dispersal over the habitable world. Long and often as Italy had to submit to foreign dominion, the idea of the national unity of the peninsula was never lost.
The process of territorial growth.
In vast unobstructed territories, on the other hand, the evil of wide, sparse dispersal is checked only by natural increase of population and the impinging of one growing people upon another, which restricts the territory of either. When the boundary waste between the small scattered tribal groups has been occupied, encroachment from the side of the stronger follows; then comes war, incorporation of territory, amalgamation of race and coalescence, or the extinction of the weaker. The larger people, commanding its larger area, expands numerically and territorially, and continues to throw out wider frontiers, till it meets insurmountable natural obstacles or the confines of a people strong as itself. After a pause, during which the existing area is outgrown and population begins to press harder upon the limits of subsistence, the weight of a nation is thrown against the barrier, be it physical or political. In consequence, the old boundaries are enlarged, either by successful encroachment upon a neighbor, or, in case of defeat, by incorporation in the antagonist's territory. But even defeat brings participation in a larger geographic base, wider coöperation, a greater sum total of common national interests, and especially the protection of the larger social group. The Transvaal and the Orange Free State find compensation for the loss of independence by their incorporation in the British Empire, even if gradual absorption be the destiny of the Boer stock.
