renewal of the folk-wandering of primitive ages. That is a misleading view: the movement has been far more deliberate and organised, and far less due to the pressure of external circumstances, than the early movements of peoples in the Old World. Not until the nineteenth century, when the industrial transformation of Europe brought about a really acute pressure of population, can it be said that the mere pressure of need, and the shortage of sustenance in their older homes, has sent large bodies of settlers into the new lands. Until that period the imperial movement has been due to voluntary and purposive action in a far higher degree than any of the blind early wanderings of peoples. The will-to-dominion of virile nations exulting in their nationhood; the desire to obtain a more abundant supply of luxuries than had earlier been available, and to make profits therefrom; the zeal of peoples to impose their mode of civilisation upon as large a part of the world as possible; the existence in the Western world of many elements of restlessness and dissatisfaction, adventurers, portionless younger sons, or religious enthusiasts: these have been the main operative causes of this huge movement during the greater part of the four centuries over which it has extended. And as it has sprung from such diverse and conflicting causes, it has assumed an infinite variety of forms; and both deserves and demands a more respectful study as a whole than has generally been given to it.

THE ERA OF IBERIAN MONOPOLY

During the Middle Ages the contact of Europe with the rest of the world was but slight. It was shut off by the great barrier of the Islamic Empire, upon which the Crusades made no permanent impression; and although the goods of the East came by caravan to the Black Sea ports, to Constantinople, to the ports of Syria, and to Egypt, where they were picked up by the Italian traders, these traders had no direct knowledge of the countries which were the sources of their wealth. The threat of the Empire of Genghis Khan in the thirteenth century aroused the interest of Europe, and the bold friars, Carpini and Rubruquis, made their way to the centres of that barbaric sovereign's power in the remote East, and brought back stories of what they had seen; later the Poli, especially the great Marco, undertook still more daring and long-continued journeys, which made India and Cathay less unreal to Europeans, and stimulated the desire for further knowledge. The later mediaeval maps of the world, like that of Fra Mauro (1459),[3] which incorporate this knowledge, are less wildly imaginative than their predecessors, and show a vague notion of the general configuration of the main land-masses in the Old World. But beyond the fringes of the Mediterranean the world was still in the main unknown to, and unaffected by, European civilisation down to the middle of the fifteenth century.

[3] Simplified reproductions of this and the other early maps alluded to are printed in Philip's Students' Atlas of Modern History, which also contains a long series of maps illustrating the extra-Europeans activities of the European states.

Then, suddenly, came the great era of explorations, which were made possible by the improvements in navigation worked out during the fifteenth century, and which in two generations incredibly transformed the aspect of the world. The marvellous character of this revelation can perhaps be illustrated by the comparison of two maps, that of Behaim, published in 1492, and that of Schoener, published in 1523. Apart from its adoption of the theory that the earth was globular, not round and flat, Behaim's map shows little advance upon Fra Mauro, except that it gives a clearer idea of the shape of Africa, due to the earlier explorations of the Portuguese. But Schoener's map shows that the broad outlines of the distribution of the land-masses of both hemispheres were already in 1523 pretty clearly understood. This astonishing advance was due to the daring and enterprise of the Portuguese explorers, Diaz, Da Gama, Cabral, and of the adventurers in the service of Spain, Columbus, Balboa, Vespucci, and—greatest of them all—Magellan.

These astonishing discoveries placed for a time the destinies of the outer world in the hands of Spain and Portugal, and the first period of European imperialism is the period of Iberian monopoly, extending to 1588. A Papal award in 1493 confirmed the division of the non-European world between the two powers, by a judgment which the orthodox were bound to accept, and did accept for two generations. All the oceans, except the North Atlantic, were closed to the navigators of other nations; and these two peoples were given, for a century, the opportunity of showing in what guise they would introduce the civilisation of Europe to the rest of the globe. Pioneers as they were in the work of imperial development, it is not surprising that they should have made great blunders; and in the end their foreign dominions weakened rather than strengthened the home countries, and contributed to drag them down from the high place which they had taken among the nations.

The Portuguese power in the East was never more than a commercial dominion. Except in Goa, on the west coast of India, no considerable number of settlers established themselves at any point; and the Goanese settlement is the only instance of the formation of a mixed race, half Indian and half European. Wherever the Portuguese power was established, it proved itself hard and intolerant; for the spirit of the Crusader was ill-adapted to the establishment of good relations with the non-Christian peoples. The rivalry of Arab traders in the Indian Ocean was mercilessly destroyed, and there was as little mercy for the Italian merchants, who found the stream of goods that the Arabs had sent them by way of the Red Sea and the Persian Gulf almost wholly intercepted. No doubt any other people, finding itself in the position which the Portuguese occupied in the early sixteenth century, would have been tempted to use their power in the same way to establish a complete monopoly; but the success with which the Portuguese attained their aim was in the end disastrous to them. It was followed by, if it did not cause, a rapid deterioration of the ability with which their affairs were directed; and when other European traders began to appear in the field, they were readily welcomed by the princes of India and the chieftains of the Spice Islands. In the West the Portuguese settlement in Brazil was a genuine colony, or branch of the Portuguese nation, because here there existed no earlier civilised people to be dominated. But both in East and West the activities of the Portuguese were from the first subjected to an over-rigid control by the home government. Eager to make the most of a great opportunity for the national advantage, the rulers of Portugal allowed no freedom to the enterprise of individuals. The result was that in Portugal itself, in the East, and in Brazil, initiative was destroyed, and the brilliant energy which this gallant little nation had displayed evaporated within a century. It was finally destroyed when, in 1580, Portugal and her empire fell under the dominion of Spain, and under all the reactionary influences of the government of Philip II. By the time this heavy yoke was shaken off, in the middle of the seventeenth century, the Portuguese dominion had fallen into decay. To-day nothing of it remains save 'spheres of influence' on the western and eastern coasts of Africa, two or three ports on the coast of India, the Azores, and the island of Magao off the coast of China.

The Spanish dominion in Central and South America was of a different character. When once they had realised that it was not a new route to Asia, but a new world, that Columbus had discovered for them, the Spaniards sought no longer mainly for the riches to be derived from traffic, but for the precious metals,
