furnished raw materials, western Africa provided the labor force to produce the raw materials, and the imperial center, often referred to as the Mother Country, shipped manufactured goods to both. Historians pointed to inequities in this system as an important cause of the American Revolution.
Contemporaries called the tropical dietary items that acted as energizers and appetite appeasers for the population on either side of the Atlantic and in Asia groceries. They included tobacco, sugar, sugar byproducts such as molasses and rum, and caffeine drinks, namely tea, coffee, and cocoa. America became the prime site for growing all of these crops except for tea and the enslaved migrants from Africa became the prime cultivators. Tobacco and the beans to make cocoa were indigenous to America while others -- coffee and sugar -- were transferred over to take advantage of the low cost of land and the bound labor force. Because many of these plantation commodities were thought of as luxuries -- that is, not essential for human survival -- their central role in the expansion of the world economy has been often overlooked (4). That is a misconception, however. By the late seventeenth century, the Dutch and the English dominated the carrying trade over the Atlantic. 74 percent of the value of imports coming into Amsterdam and more than 85 percent coming into London from colonies in America consisted of tobacco and sugar products (5). Portraits, aristocratic and more middling class, as in the household shown here [see Figure 2], often displayed the paraphernalia -- tea service, porcelain tea cups, sugar bowls, clay pipes, snuff boxes -- associated with the consumption of these tropical groceries. By the eighteenth century, the laboring classes also used these groceries on a regular basis (6).
The old histories of mercantilism centered their story on the infusion of Spanish empire silver and gold, the rampant inflation in Europe it produced, and its role in the underdevelopment of Spain and its colonies. The new version of this story considers inflation less of a problem and concentrates on the enormity of Chinese demand for silver, which was needed both to expand its monetary system and to manufacture silver wares. Its willingness to offer advantageous terms of trade for those sought-after commodities created a global commercial network in which America and Africa supplied the bullion and foodstuffs to pay for Asian commodities distributed largely in European ships (12).
built a commercial center at Macao on the west banks of the Pearl, the river which leads to the Chinese port of Canton. [Figure 4 indicates the size of the European enclave.] Not until later in the nineteenth century did Hong Kong, on the east side of the Pearl River, overtake Macao. Both cities remained under the control of western Europeans until the end of the twentieth century. Manila, the Spanish entrepôt, also spent most of its history as a colony. Originally, however, these outposts had been set up because it was the only way westerners could obtain Chinese products.
Regardless of the approach, it seems clear that the economic order that took shape after the European discovery of America redistributed unprecedented numbers of people to satisfy a growing global demand for its resources and products that in turn kept more labor and capital flowing in to the so-called new world. Overseas trade has been identified as the leading sector in economic growth during this period. Even in well established European nations, growth depended primarily on the expansion of the overseas trade sector (16). A major impetus for the adoption of the U.S. Constitution was the belief that survival as a nation depended on overseas commerce and that its success required a strong central government. [See Figure 5 for a map that identifies some of the major global trade routes of the eighteenth century.]
