Commerce between nations has always stimulated economic development. In the nineteenth century, Europe directed an enormous increase in international commerce. Great Britain took the lead in cultivating export markets for its booming industrial output, as British manufacturers looked first to Europe and then around the world.

Take the case of cotton textiles. By 1820, Britain was exporting 50 percent of its production. Europe bought 50 percent of these cotton textile exports, while India bought only 6 percent and had its own well-established textile industry. Then as European nations and the United States erected protective tariff barriers to promote domestic industry, British cotton textile manufacturers looked to markets in non-Western areas. By 1850, India was buying 25 percent and Europe only 16 percent of a much larger volume of production. As a British colony, India could not raise tariffs to protect its indigenous cotton textile industry, which consequently collapsed.

In addition to its dominance in the export market, Britain was also the world’s largest importer of agricultural products, raw materials, and manufactured goods. Under free-trade policies, open access to Britain’s market stimulated the development of mines and plantations in many non-Western areas.

International trade grew as transportation systems improved. European investors funded much of the railroad construction undertaken in Latin America, Asia, and Africa, which connected seaports with resource-rich inland cities and regions, as opposed to linking and developing cities and regions within a given country. Thus railroads dovetailed effectively with Western economic interests, facilitating the inflow and sale of Western manufactured goods and the export and the development of local raw materials.

The power of steam revolutionized transportation by sea as well as by land. Steam power began to supplant sails on the oceans of the world in the late 1860s. The time needed to cross the Atlantic dropped from three weeks in 1870 to about ten days in 1900, and the opening of the Suez and Panama Canals (in 1869 and 1914, respectively) shortened transport time to other areas of the globe considerably.

The revolution in land and sea transportation encouraged European entrepreneurs to open up and exploit vast new territories around the world. Improved transportation enabled Asia, Africa, and Latin America to ship not only familiar agricultural products but also new raw materials for industry, such as jute, rubber, cotton, and coconut oil. The export of raw materials supplied by these “primary producers” to Western manufacturers boosted economic growth in core countries but did little to establish independent industry in the nonindustrialized periphery.

New communications systems were used to direct the flow of goods across global networks. Transoceanic telegraph cables, firmly in place by the 1880s, enabled rapid communications among the financial centers of the world. The same communications network conveyed world commodity prices instantaneously.

As their economies grew, Europeans began to make massive foreign investments beginning about 1840. By the outbreak of World War I in 1914, Europeans had invested more than $40 billion abroad (Map 24.1). The great gap between rich and poor within Europe meant that the wealthy and moderately well-to-do could and did send great sums abroad in search of interest and dividends.

About three-quarters of total European investment went to other European countries, or to settler colonies or neo-Europes — regions that already had significant populations of ethnic Europeans, including the United States, Canada, Australia, New Zealand, Latin America, and Siberia. Europe found its most profitable opportunities for investment in construction of the railroads, ports, and utilities that were necessary to settle and develop the lands in places such as Australia and the Americas. By lending money to construct foreign railroads, Europeans enabled white settlers to buy European rails and locomotives and to develop sources of cheap food and raw materials.

The extension of Western economic power and the construction of neo-Europes were disastrous for indigenous peoples. Native Americans and Australian aborigines especially were decimated by the diseases, liquor, and weapons of an aggressively expanding Western society.
