the limits of a single country. Under external migration are
comprised emigration and immigration, denoting simply direction
from and to. The emigrants are at the same time the immigrants;
that is, the material of the movement is the same,
but the effect upon the country giving up and the country
receiving the migrant requires separate treatment. Hence
it is proper to separate emigration from immigration. Temporary
migration, or travel for purposes of business, enterprise
or pleasure, will be considered only incidentally, and because
in some cases it is difficult to distinguish between such
movements and permanent migration.
Migration in general may be described as a natural function of social development. It has taken place at all times and in the greatest variety of circumstances. It has been tribal, national, class and individual. Its causes have been political, economic, religious, or mere love of adventure. Its causes and results are fundamental for the study of ethnology (formation and mixture of races), of political and social history (formation of states and survival of institutions), and of political economy (mobility of labour and utilization of productive forces). Under the form of conquest it makes the grand epochs in history (e.g. the fall of the Roman Empire); under the form of colonization it has transformed the world (e.g. the settlement of America); under free initiative it is the most powerful factor in social adjustment (e.g. the growth of urban population). It must suffice here to indicate the character of the principal movements in the past, and then describe certain aspects of modern migration. The early movements may be grouped as follows: (a) Prehistoric migrations. Among savage and nomadic nations the whole tribe often moves into new territory, either occupying it for the first time or exterminating or driving out the indigenous inhabitants. We have only vague knowledge of these early movements, laboriously gleaned from archaeology, anthropology and philology. The cause has been commonly said to be the pressure of population on the food-supply. A more probable explanation is the love of booty and the desire of the stronger to take possession of the lands of the weaker. (b) Greek and Roman colonization. Both of these ancient civilizations extended their influence through migration of individual families and the planting of colonies. The motive seems to have been primarily commercial—that is, the love of gain. It may have been partly a sort of “swarming” process, caused by pressure of population at home. In some cases it had a political motive, as the planting of military colonies or providing new homes for the proletariat. The consequences were of course momentous. (c) The German Conquest. Beginning about the 5th century, the Roman empire was overthrown by German tribes from the north of the river Danube and east of the river Rhine. This Völkerwanderung, as it is called by German historians, again transformed the face of Europe, resulting in the establishment of independent kingdoms and a great mixture of races and institutions. It was coincident with the building-out of the feudal system. The conquered in many cases could be left as serfs and tillers of the soil, while the conquerors seized the higher positions of administration and power. (d) The later middle ages saw many minor migratory movements, such as those accompanying the crusades, the pushing of German colonization among the Slavs, and the introduction of Flemish weavers into England. The religious reformation caused a considerable amount of expatriation, culminating in the expulsion of the Huguenots from France. (e) The period of discovery and colonization opened up a new era for migration. The first expeditions were for adventure and booty, especially the discovery of gold and silver. Then came the establishment of commercial posts or factories for the purposes of trade. Finally came colonization proper—that is, the settlement of new countries by Europeans intending to remain there permanently, but still retaining their connexion with the mother country. This meant the opening up of the world to commerce and the extension of European civilization to vast areas formerly peopled by savages or half-civilized peoples. It meant a great outlet for the spirit of enterprise and adventure, relief from over-population, an enormous increase in wealth and power, and a struggle for supremacy among the nations of Europe. Colonization and colonial policy excited immense attention in Europe; and this extended into the 19th century (e.g. E. G. Wakefield’s plans for colonization, and the various colonization societies of modern times). The colonial policy proper was broken down by the revolt of the North American colonies from Great Britain, and later of Mexico and Central and South America from Spain. (f) The movement of population, however, has continued under the form of emigration. This movement is characterized firstly by its magnitude; secondly, by the fact that the emigrant changes his political allegiance, for by far the greater part of modern emigration is to independent countries, and even where it is to colonies the colonies are largely self-governing and self-regarding; and thirdly, it is a movement of individuals seeking their own good, without state direction or aid. This is 20th-century emigration, differing from all preceding forms and having an importance of its own.
