AA POIGNANT HUMAN DRAMA WAS INTERWOVEN with this worldwide economic expansion: millions of people left their ancestral lands in one of history’s greatest migrations, the so-called great migration. In the early eighteenth century the world’s population entered a period of rapid growth that continued unabated through the nineteenth and twentieth centuries. Europe’s population (including Asiatic Russia) more than doubled during the nineteenth century. Since African and Asian populations increased more slowly than those in Europe, Europeans and peoples of predominantly European origin jumped from about 22 percent of the world’s total in 1850 to a high of about 38 percent in 1930.

Rapid population growth led to relative overpopulation in area after area in Europe and was a driving force behind emigration and Western expansion. Millions of country folk moved to nearby cities, and the more adventuresome went abroad, in search of work and economic opportunity. Wars, famine, poverty, and, particularly in the case of Russian and eastern European Jews, bigotry and discrimination were also leading causes for emigrants to leave their ancestral homelands. More than 60 million people left Europe over the course of the nineteenth century, primarily for the rapidly growing “areas of European settlement” — North and South America, Australia, New Zealand, and Siberia (see Chapter 27).

The European migrant was most often a small peasant landowner or a village craftsman whose traditional way of life was threatened by too little land, estate agriculture, and cheap factory-made goods. Determined to maintain or improve their precarious status, the vast majority of migrants were young and often unmarried. Many European migrants returned home after some time abroad.

Ties of family and friendship played a crucial role in the movement of peoples. Over several years a given province or village might lose significant numbers of its inhabitants to migration. These then settled together in rural enclaves or tightly knit urban neighborhoods in foreign lands thousands of miles away. Very often a strong individual — a businessman, a religious leader — blazed the way, and others followed, forming a migration chain.

A substantial number of Asians — especially Chinese, Japanese, Indians, and Filipinos — also responded to population pressure and rural hardship with temporary or permanent migration. At least 3 million Asians moved abroad before 1920. Most went as indentured laborers to work on the plantations or in the gold mines of Latin America, southern Asia, Africa, California, Hawaii, and Australia (see Chapter 26). White estate owners often used Asians to replace or supplement black Africans after the suppression of the Atlantic slave trade.

Asian migration would undoubtedly have been much greater if planters and mine owners desiring cheap labor had had their way. But usually they did not. Asians fled the plantations and gold mines as soon as possible, seeking greater opportunities in trade and towns. Here, however, they came into conflict with white settlers, who demanded a halt to Asian immigration. By the 1880s Americans and Australians were building great white walls — discriminatory laws designed to keep Asians out.

The general policy of “whites only” in the lands of large-scale European settlement meant that Europeans and people of European ancestry reaped the main benefits of the great migration. By 1913 people in Australia, Canada, and the United States all had higher average incomes than did people in Great Britain, still Europe’s wealthiest nation. This, too, contributed to Western dominance in the increasingly lopsided world.

Within Asia and Africa the situation was different. Migrants from south China frequently settled in Dutch, British, and French colonies of Southeast Asia, where they established themselves as peddlers and small shopkeepers (see Chapter 26). These “overseas Chinese” gradually emerged as a new class of entrepreneurs and office workers. Traders from India and modern-day Lebanon performed the same function in much of sub-Saharan Africa after European colonization in the late nineteenth century. Thus in some parts of Asia and Africa the business class was both Asian and foreign, protected and tolerated by Western imperialists who found these business people useful.
