Wealth of Nations

Book V.
Of the Revenue of the Sovereign or Commonwealth

Part I. Of the Expense of Defense

The first duty of the sovereign, that of protecting the society from the violence and invasion of other independent societies, can be performed only by means of a military force. But the expense both of preparing this military force in time of peace, and of employing it in time of war, is very different in the different states of society, in the different periods of improvement.

Among nations of hunters, the lowest and rudest state of society, such as we find it among the native tribes of North America, every man is a warrior, as well as a hunter. When he goes to war, either to defend his society, or to revenge the injuries which have been done to it by other societies, he maintains himself by his own labor, in the same manner as when he lives at home. His society (for in this state of things there is properly neither sovereign nor commonwealth) is at no sort of expense, either to prepare him for the field, or to maintain him while he is in it.

Among nations of shepherds, a more advanced state of society, such as we find it among the Tartars and Arabs, every man is, in the same manner, a warrior. Such nations have commonly no fixed habitation, but live either in tents, or in a sort of covered wagons, which are easily transported from place to place. The whole tribe, or nation, changes its situation according to the different seasons of the year, as well as according to other accidents. When its herds and flocks have consumed the forage of one part of the country, it removes to another, and from that to a third. In the dry season, it comes down to the banks of the rivers; in the wet season, it retires to the upper country. When such a nation goes to war, the warriors will not trust their herds and flocks to the feeble defense of their old men, their women and children; and their old men, their women and children, will not be left behind without defense, and without subsistence. The whole nation, besides, being accustomed to a wandering life, even in time of peace, easily takes the field in time of war. Whether it marches as an army, or moves about as a company of herdsmen, the way of life is nearly the same, though the object proposed by it be very different. They all go to war together, therefore, and everyone does as well as he can. Among the Tartars, even the women have been frequently known to engage in battle. If they conquer, whatever belongs to the hostile tribe is the recompense of the victory; but if they are vanquished, all is lost; and not only their herds and flocks, but their women and children. become the booty of the conqueror. Even the greater part of those who survive the action are obliged to submit to him for the sake of immediate subsistence. The rest are commonly dissipated and dispersed in the desert.

The ordinary life, the ordinary exercise of a Tartar or Arab, prepare him sufficiently for war. Running, wrestling, cudgel-playing, throwing the javelin, drawing the bow, etc. are the common pastimes of those who live in the open air, and
