The Dutch knocked off the Portuguese, and were in turned knocked off by the British. In addition to altering Asian–European trade routes, this so-called Age of Discovery is associated with Europeans’ colonization of North and South America—an event that would help reverse ten millennia of economic dominance by Eurasian civilizations. The Columbian Exchange: Food Crops for Epidemics The shift of the planet’s economic center of gravity to the North Atlantic was based in part on the so-called Columbian Exchange. Imported food crops from the Americas—especially potatoes and maize—were imperative in allowing Europe to gain critical levels of population density. In exchange, Europeans brought new diseases that depopulated the New World and almost erased the ancient civilizations in Mesoamerica and the Andes. Both effects are illustrated in Figure 13.

Economically and geographically, Europe was “a small promontory of Asia,” as historian Felipe Fernández-Armesto puts it in his 1995 book Millennium: A History of the Last Thousand Years.10 Proto-Globalization, 1450 to 1776 The opening of the Silk Road proved to be a key stage in globalization’s long history. Its shutting in 1450 was equally notable. It launched a period described by historian Anthony Hopkins as proto-globalization—a preparatory stage for the dramatic shift that was to come in Phase Three. Proto-globalization rested on three pillars: the Renaissance and Enlightenment, the Age of Discovery, and the Columbian Exchange. Renaissance and Enlightenment In the fourteenth century, Europe started transforming itself from the western periphery of Asian civilization into the world’s leading economic and military power. John Hobson, Ferdinand Braudel, and Ian Morris argue that much of the European revival was based on ideas, institutions, and technologies borrowed from the advanced civilizations in the Middle and Far East—much of which had been preserved, integrated, and extended by Islamic scholars during the Golden Age of Islam.

Water transportation advanced with new types and layouts of sails, new shipbuilding techniques, and big advances in navigational technology. By the 1700s, Europeans had mapped the world and were navigating the seas with ease. Colonialism continued to be developed—especially by the British, French, and Dutch. The independence movements in North and South America did nothing to disrupt trade and economic development in the Atlantic. FIGURE 13: Populations in Europe and the Americas, year 1 to 1820. The Columbian Exchange boosted European populations via the introduction of new food staples. It also decimated New World populations via the introduction of Old World diseases like smallpox, measles, and typhus. This set up a situation where the Old World had too many people and not enough land—an imbalance mirrored by the opposite imbalance in the New World. Note the scale for the Old World chart is about ten times that of the New World chart.

The New World that Columbus opened to other conquistadors and explorers—Hernando Cortés, Francisco Pizarro, and Vasco Nuñez de Balboa—during the wind-powered Age of Discovery had little resemblance to the Old World. Reconstruction of Columbus’s diaries note his observation that “all the trees are as different from ours as day from night; and also the fruits and grasses and stones and everything.” This difference was not to last. Alfred Crosby, the historian who coined the term for the “Columbian Exchange,” the transcontinental transfer of species following Columbus’s voyages, wrote of the day that Columbus landed ashore on the Bahamas: “The two worlds, which were so very different, began on that day to become alike. That trend toward biological homogeneity is one of the most important aspects of the history of life on this planet since the retreat of the continental glaciers.” The sun-powered homogenization was partially intentional and partially accidental.

Some of the oldest and largest qanats still exist, such as one in the Iranian city of Gonabad that still provides irrigation and drinking water to nearly 40,000 people. Qanats can move water only so far, and other inventions, such as dams and wells, are also only local solutions. But trade—the other, more hidden and surreptitious way to move water—involves much greater distances. The sun-powered sails that made the Columbian Exchange and guano part of the story of humanity’s domination of the planet also made possible the virtual trade in water. Moving water virtually, in products grown or raised with large amounts of water, spread the vital resource farther than was ever possible with Mesopotamia’s irrigation canals or the ingenious qanats. Sugar, coffee, tea, oranges, rice, wheat, or any other crop that grows where water and sun are abundant could feed people in places with more meager endowments, so long as there was trade.

Egypt’s Old Kingdom is thought to have had between 1.2 and 2 million people; the Middle Kingdom between 2 and 3 million. There was probably a peak of 6 or 7 million at the start of the Ptolemaic period, but this fell somewhat by Roman times. As recently as 1882, the total was still only 6.7 million, showing no overall gain in the more than 2,000 years since the pharaohs (Alfred Crosby, The Columbian Exchange: Biological and Cultural Consequences of 1492 [Westport, CN: Greenwood Press, 1972], p. 190). By 1964, it had risen to 28.9 million; Crosby attributes much of this rise to the introduction of maize. Since 1964, the population has doubled again, but Egyptians now are eating mainly imported wheat and feeding their maize to livestock (see Timothy Mitchell, “The Object of Development: America’s Egypt,” in Jonathan Crush, ed., The Power of Development [London: Routledge, 1995]). 72. 150 per square kilometre. 73.

Manco and his sons later set up an Inca free state from which they waged guerrilla war for nearly forty years. Modern civil wars in Peru and Guatemala during the 1980s, in Chiapas during the 1990s, and the 1990 Oka crisis in Canada were all fuelled by unfinished business between whites and Amerindians. However, leaders of the Shining Path uprising in Peru were exploiters of Peruvian nativism, not its champions. 16. Fray Motolinía, quoted in Crosby, Columbian Exchange, p. 52. 17.

This is especially true of North America and parts of the lowland tropics, where a century or more went by between the collapse of the old population and the arrival of the new. Like the Maya jungles, much of eastern North America’s “virgin forest” was secondary growth on abandoned Indian cornfields, towns, and parklike hunting lands.

Botany was regarded as the “big science” of its day, an indication of a country’s might and sophistication, just as mastery of nuclear science or space technology is thought to be today. All this meant that the pineapple presented to Charles II was more than a mere fruit; it was a vivid symbol of his power. As European explorers, colonists, botanists, and traders sought out new plants, learned how to nurture them, and worked out where else in the world they might also thrive, they reshaped the world’s ecosystems. The “Columbian Exchange” of food crops between the Old and New worlds, in which wheat, sugar, rice, and bananas moved west and maize, potatoes, sweet potatoes, tomatoes, and chocolate moved east (to list just a handful of examples in each direction), was a big part of the story, but not the only part; Europeans also moved crops around within the Old and New worlds, transplanting Arabian coffee and Indian pepper to Indonesia, for example, and South American potatoes to North America.

Had he known this in 1675, Charles II would no doubt have been proud, though he might have been disappointed to hear that the pineapple was not one of the many foods that would play a part in this tale. Instead, the two foods that are central to the story are sugar, which traveled west across the Atlantic, and the potato, which traveled in the opposite direction. COLUMBUS AND HIS EXCHANGE The Columbian Exchange, as the historian Alfred Crosby has called it, was aptly named because it really did start with Christopher Columbus himself. Although many other people carried plants, animals, people, diseases, and ideas between the Old and New worlds in the years to follow, Columbus was directly responsible for two of the earliest and most important exchanges of food crops with the Americas. On November 2, 1492, having arrived at the island of Cuba, he sent two of his men, Rodrigo de Jerez and Luis de Torres, into the interior with two local guides.

Estimates of the size of the pre-Columbian population of the Americas vary from 9 million to 112 million, but a consensus figure of 50 million, which had been reduced by disease and warfare to some 8 million by 1650, gives an idea of the scale of the destruction. Even as their invisible biological allies wiped out the indigenous peoples of the Americas, Europeans began importing slaves from Africa on a vast scale to work on sugar plantations. The demographics of Africa and the Americas were transformed. But the Columbian Exchange also helped to alter the demographics of Eurasia. In China, the arrival of maize and sweet potatoes contributed to the increase in population from 140 million in 1650 to 400 million in 1850. Since maize could be grown in areas that were too dry for rice, and on hillsides that could not be irrigated, it added to the food supply and allowed people to live in new places. The uplands of the Yangtze basin were deforested to make way for the production of indigo and jute, for example, and the peasants who grew them lived on maize and sweet potatoes, which grew well in the hills.

The most famous example is what the geographer and historian Alfred Crosby has called the “Columbian Exchange,” the horrific, unintended fallout of Europe’s conquest of the New World since 1492 CE. Entirely separate disease pools had evolved in Europe and the Americas. America had unpleasant ailments of its own, such as syphilis, but the small, rather thinly spread American populations could not begin to compete with Europe’s rich repertoire of microbes. The colonized peoples were epidemiological virgins. Everything from measles and meningitis to smallpox and typhus—and plenty in between—invaded their bodies when the Europeans arrived, rupturing their cells and killing them in foul ways. No one knows for sure how many died, but the Columbian Exchange probably cut short the lives of at least three out of every four people in the New World.

Spaniards liked to joke that their imperial overlords in Madrid were so inefficient that “if death came from Spain, we would all live forever,” but Native Americans probably did not find that very funny. For them death did come from Spain. Shielded by the Atlantic and Pacific oceans, they had evolved no defenses against Old World germs, and within a few generations of Columbus’s landfall their numbers fell by at least three-quarters. This was the “Columbian Exchange” mentioned in Chapter 6: Europeans got a new continent and Native Americans got smallpox. Although European colonists sometimes visited horrifying cruelty on the people they encountered, death came to natives mostly unseen, as microbes on the breath or in body fluids. It also raced far ahead of the Europeans themselves, transmitted from colonists to natives and then spread inland every time an infected native met one who was still healthy.

By the end of the medieval period, the gradual merging of the Old World’s regional disease pools in the wake of commercial and eventually military contacts had ensured maximum coverage, causing many of these killer diseases to become endemic. By contrast, indigenous Americans enjoyed a less severe disease environment and lacked any prior exposure to these Old World scourges. Exploration and conquest opened up what Alfred Crosby called the “Columbian exchange,” transatlantic contacts that swiftly introduced a plethora of lethal infections to the Americas. And although the New World returned the favor by sending syphilis the other way, the European pathogen contribution to the Americas was much more diverse and vastly more catastrophic.1 Smallpox and measles were the most devastating of the diseases introduced by Europeans: long endemic as early childhood diseases in the Old World, they struck the Americas in epidemic outbreaks.

Spanning as they do much of recorded human history and several continents, what all these cases have in common is that substantial reductions in resource inequality depended on violent disasters. This raises two pressing questions: Has there been no other way to level inequality? And is there now? It is time to explore less bloody alternatives to our Four Horsemen. 1 See Diamond 1997: 195–214 for the differences between the pre-Columbian Old and New World disease pools. Crosby 1972 and 2004 are classic accounts of the Columbian exchange. For a very brief summary, see Nunn and Qian 2010: 165–167. 2 The following survey is based on Cook 1998.

Arroyo Abad, Davies, and van Zanden 2012: 158 note that the quadrupling of real wages in Mexico between the sixteenth and the mid-seventeenth century is logically consistent with a population loss of about 90 percent, a tantalizing if inconclusive bit of support for very high mortality estimates; see herein.

Their field work in many ways echoes the expeditions of those quirky Victorian naturalists who scoured the globe to add botanical curiosities to their collections. But were it not for the efforts of Chetelat and his predecessors and colleagues at the Rick Center to find and conserve all seventeen species that make up the tomato family, there is a very real possibility that tomato production as we know it today would not exist. Of all the species that played a part in the great Columbian Exchange—the widespread mingling of plants, animals, and disease organisms between the Eastern and Western hemispheres following the establishment of Spanish colonies in the New World—the tomato surely would have topped the list as the least likely to succeed, never mind to become one of our favorite vegetables. Botanists think that the modern tomato’s immediate predecessor is a species called S. pimpinellifolium that still grows wild in the coastal deserts and Andean foothills of Ecuador and northern Peru.

Though often dense, and occasionally dated (the first volume appeared in 1978), the Handbook examines every region, era, and tribe in North America, from every perspective: archaeological, demographic, linguistic, political, religious, musical, and so on. There are a number of excellent books about environmental history and the interchange of plants, animals, and microorganisms known as the Columbian Exchange. Pioneering works in this field include Alfred Crosby’s Ecological Imperialism: The Biological Expansion of Europe, 900–1900 and William Cronon’s Changes in the Land: Indians, Colonists, and the Ecology of New England. More recent is Charles Mann’s 1491: New Revelations of the Americas Before Columbus, an excellent and balanced overview of current scholarship on the Columbian Exchange, disease, and New World demography. My material on Verrazzano is mostly drawn from Lawrence Wroth’s The Voyages of Giovanni da Verrazzano, which includes not only the navigator’s writings but a comprehensive look at what’s known about his life and voyages, as well as the geographical thinking of his day.

Now consider the contribution of trade to our planet's agricultural bounty. Try to imagine Italian cuisine without the tomato, the highlands around Darjeeling without tea plants, an American table without wheat bread or beef, a cafe anywhere in the world beyond coffee's birthplace in Yemen, or German cooking without the potato. Such was the world's limited range of farm produce before the "Columbian exchange," the invasion of billions of acres of cropland by species from remote continents in the decades following 1492. How and why did this occur, and what does it tell us about the nature of trade? During the seven centuries between the death of the Prophet Muhammad and the Renaissance, the Muslim states of Europe, Asia, and Africa outshone and towered over western Christendom. Muhammad's followers dominated the great conduit of long-range world commerce, the Indian Ocean, and in the process spread his powerful message from west Africa to the South China Sea.

Rhode observe in their 2008 survey of American agricultural history, the varieties of corn, wheat, fruits, cotton, and tobacco grown at the beginning of the 20th century were dramatically different from the varieties grown one hundred years earlier, while 1940s farm animals such as swine, sheep, and cattle bore little resemblance to those of 1800.10 Of course, along the way innovative farmers adopted and adapted domesticated plants and animals that had been developed in distant lands, such as in the “Columbian exchange” that followed the incorporation of the Americas into the world economy more than 500 years ago. Native American contributions included edible crops like the tomato, potato, sweet potato, chili pepper, cocoa, pineapples, beans, cassava, and corn, as well as tobacco and some varieties of cotton. Many products refined in the Old World, from wheat, rice, and soybeans to onions and peaches and virtually all of its domestic animals, traveled west and significantly altered the American landscape.

Educated people had long known that the earth was round, but they had no idea of its circumference. The conquests of Mexico and Peru gave Spaniards access to Aztec and Incan mines as well. Gold and silver extracted from these mines began pouring into Europe. Far more important, the ships crossing the Atlantic brought animals and plants that dramatically transformed the societies on both sides of the ocean. What has been called the Columbian exchange completed the biological and botanic homogeneity of our planet.2 Alas, germs lethal to the inhabitants of the New World were part of that exchange. The arrival of newcomers in the Western Hemisphere triggered an unintended holocaust, for the Europeans carried with them lethal microorganisms against which the native population had no protection. Exposed to these Old World diseases with no immunity, the entire population of Arawaks on San Domingo died within a generation.

Disease usually came along for the ride, with consequences that reshaped the world. The historian Ian Morris has described how increased trade around the second century CE merged previously separate disease pools that, since the beginning of agriculture, had evolved in the West, South Asia, and East Asia, “as if they were on different planets.” Catastrophic plagues broke out in China and in the eastern outposts of the Roman Empire.25 The Columbian exchange after 1492 is an even better-known example.26 Many historical epidemics started from new trade routes or new conquests. The plague of Athens in 430 BCE was attributed to trade, and bubonic plague was brought to Europe in 1347 by rats aboard trading ships. The cholera epidemic of the nineteenth century is thought to have come from Asia thanks to the activities of the British in India, and its subsequent spread through Europe and North America was speeded by the new railways.

Nor did a technical ‘lag’ create a real disparity between the military capacity of European states and those in the rest of Eurasia. On the contrary. The threat of further Ottoman expansion hung over Europe until the 1690s. In India and East Asia, Europe’s remoteness made its mode of land warfare almost entirely irrelevant. In much the same way, patterns of consumption, codes of social etiquette and notions of hierarchy in the rest of Eurasia showed few signs of being influenced by Europeans’ behaviour. The ‘Columbian Exchange’ between the natural products of the Old World and the New diversified Eurasian agriculture with novel plants like maize and potatoes, but created no dependence upon European suppliers.124 European activity in the Americas aroused little if any interest in the rest of Eurasia.125 Islamic and East Asian cosmology showed no loss of confidence in the face of European learning, or the violent upheaval in European religion and ritual.

New tools of genetic analysis indicate that this hearty lager strain contains genes from a distantly related species of Saccharomyces, called Saccharomyces eubayanus, that has been traced to Patagonia, where it is found on the bark of certain trees.* Researchers hypothesize that, shortly after Columbus’s voyages, this cold-tolerant yeast found its way to Europe, perhaps in a shipment of lumber, or in a barrel that was then used to brew beer. So it appears that lager, like the tomato and the potato and the chili pepper, is yet another gift from the New World to the Old, tendered as part of the Columbian Exchange. S. cerevisiae has demonstrated remarkable ingenuity in exploiting the human desire for alcohol, particularly in finding ways to transport itself from one batch of the stuff to another. Some strains get themselves passed on by colonizing the vessels in which alcohol is fermented, or the wooden tools used to stir the pot. “Brewing sticks” are prized possessions in parts of Africa, believed to inaugurate the miracle of fermentation when used to stir a mash—and so they do, much like Sister Noëlla’s wooden paddle.

As the technology expert Steven Johnson has argued, the unintended consequences of historical events can be far-reaching. Gutenberg made printed books affordable, which kicked off an increase in literacy, which created a market for spectacles, which led to work on lenses that in turn resulted in the invention of microscopes and telescopes, which unleashed the discovery that the earth went round the sun. In 1493, his magnificent account of the great Columbian exchange that followed contact between the eastern and western hemispheres, Charles Mann shows how again and again the forces that truly shaped history came from below, not above. For instance, the American Revolution was won by the malaria parasite, which devastated General Charles Cornwallis’s army in the Carolinas and on the Chesapeake Bay, at least as much as it was won by George Washington. I say this not as a bad-loser Brit seeking excuses, but on the authority of the distinguished (American) environmental historian J.R.
