1493_ Uncovering the New World Columbus Created - Charles C. Mann [24]
The Ming have long believed their duty is to protect China from malign foreign influence. They have failed. American crops like tobacco, maize, and sweet potato are spreading over hillsides. American silver is dominating the economy. Although the emperors don’t know it, American trees are helping to bring the rains. All of these are working against the Ming. Popular discontent is already at such levels that mobs of peasant rebels are tearing violently through half a dozen provinces. Unhappy, unpaid soldiers are mutinying. Flood and famine simply exacerbate the anger. In two years Beijing will fall to a rebellious ex-soldier. Weeks later, the soldier will be overthrown by the Manchus, who establish a new dynasty: the Qing (pronounced, roughly speaking, “ching”).
When Colón founded La Isabela, the world’s most populous cities clustered in a band in the tropics, all but one within thirty degrees of the equator. At the top of the list was Beijing, cynosure of humankind’s wealthiest society. Next was Vijayanagar, capital of a Hindu empire in southern India. Of all urban places, these two alone held as many as half a million souls. Cairo, next on the list, was apparently just below this figure. After these three, a cluster of cities were around the 200,000 mark: Hangzhou and Nanjing in China; Tabriz and Gaur in, respectively, Iran and India; Tenochtitlan, dazzling center of the Triple Alliance (Aztec empire); Istanbul (officially Kostantiniyye) of the Ottoman empire; perhaps Gao, leading city of the Songhay empire in West Africa; and, conceivably, Qosqo, where the Inka emperors plotted their next conquests. Not a single European city would have made the list, except perhaps Paris, then expanding under the vigorous rule of Louis XII. Colón’s world was centered around hot places, as had been the case since Homo sapiens first stared in amazement at the African sky.
Now, a century and a half later, that order is in the midst of change. It is as if the globe has been turned upside down and all the wealth and power are flowing from south to north. The once-lordly metropolises of the tropics are falling into ruin and decrepitude. In the coming centuries, the greatest urban centers will all be in the temperate north: London and Manchester in Britain; New York, Chicago, and Philadelphia in the United States. By 1900 every city in the top bracket will be in Europe or the United States, save one: Tokyo, the most Westernized of eastern cities. From the vantage of an extraterrestrial observer, the change would have seemed shocking; an order that had characterized human affairs for millennia had been overturned, at least for a while.
Today the tumult of ecological and economic exchange is like the background radiation of our ever more crowded and unstable planet. It seems distinctly contemporary to find Japanese loggers in Brazil and Chinese engineers in the Sahel and Europeans backpacking in Nepal or occupying the best tables in New York niteries. But in different ways all of these occurred hundreds of years ago. If nothing else, the events then remind us that we are not alone in our current jumbled condition.
