Sum­ma­ry: ‘A Splen­did Exchange: How Trade Shaped the World’

Main points

  • Long-dis­tance trade has exist­ed for mil­len­nia: It start­ed with pre­cious items like silk, gold, and spices, and evolved to include agri­cul­tur­al prod­ucts like corn, cof­fee, and cotton.
  • Trade routes and meth­ods have changed: From camels on land to ships on water, trans­porta­tion has become faster and more efficient.
  • Trade has had both pos­i­tive and neg­a­tive impacts: It has brought pros­per­i­ty to many but also led to con­flict and exploitation.
  • Glob­al­iza­tion is a com­plex process: It ben­e­fits some and hurts oth­ers, and its effects are still felt today.
  • The book cov­ers much his­to­ry, from ancient times to the present day.
  • He dis­cuss­es the role of trade in shap­ing cul­tures, economies, and polit­i­cal systems.
  • The book con­cludes with a dis­cus­sion of the chal­lenges and oppor­tu­ni­ties pre­sent­ed by globalization.

Summary: ‘A Splendid Exchange: How Trade Shaped the World’

In today’s glob­al econ­o­my, every­one is accus­tomed to pur­chas­ing goods from oth­er coun­tries – elec­tron­ics from Tai­wan, veg­eta­bles from Mex­i­co, cloth­ing from Chi­na, cars from Korea, and skirts from India. Most mod­ern shop­pers take their prod­ucts “Made in (some oth­er coun­try)” stick­ers for grant­ed. Long-dis­tance com­merce was not always this com­mon, although for­eign trade – the move­ment of goods from one geo­graph­ic region to anoth­er – has been a vital fac­tor in human affairs since pre­his­toric times. Thou­sands of years ago, mer­chants trans­port­ed only the most pre­cious items – silk, gold and sil­ver, spices, jew­els, porce­lains, and med­i­cines – via ancient, extend­ed land and sea trade routes, includ­ing the fabled Silk Road through cen­tral Asia. Mov­ing goods great dis­tances was too com­plex and cost­ly to waste the effort on ordi­nary prod­ucts. How­ev­er, peo­ple often cart­ed grain and oth­er foods over short­er dis­tances from farms to mar­ket towns.

“Man has an intrin­sic’ propen­si­ty to truck, barter and exchange one thing for anoth­er’.” [ – Adam Smith]

Numer­ous signs pro­vide clues about ancient, long-dis­tance trade, a fun­da­men­tal human activ­i­ty for mil­len­nia. In Mesopotamia, where cop­per is not indige­nous, archae­ol­o­gists uncov­ered cop­per head­gear by Sumer­ian war­riors in 3000 B.C. The Sume­ri­ans obtained the met­al from traders trav­el­ing hun­dreds of miles away from mines. Peo­ple began using boats in North­ern Europe some 15,000 years ago, and that is prob­a­bly how the ear­li­est traders moved their wares. The ear­li­est trade by water was between farm­ers who bartered food items and hunter-gath­er­ers who bartered ani­mal pelts. Obsid­i­an, ide­al for mak­ing cut­ting tools and weapons, was one of the first trade items. Greece does not nat­u­ral­ly pro­duce obsid­i­an, but arche­ol­o­gists found 12,000-year-old obsid­i­an flakes on its main­land. The stone must have come by sea from Melos, 100 miles away. Ship­ping goods by water was more acces­si­ble and cheap­er than land trans­port. Greek his­to­ri­an Herodotus describes ear­ly round boats of ani­mal hides stretched over wood­en frames. The “largest…carried about 14 tons,” but only down­stream. At the jour­ney’s end, the hides were fold­ed, packed on don­keys, and tak­en back upstream.

“On some unrecord­ed occa­sion deep in pre­his­to­ry, a man, or sev­er­al men, ini­ti­at­ed ear­ly long-dis­tance trade by set­ting out on the water in boats.”

In old­en times, trans­port­ing trade goods was a dead­ly enter­prise. Ban­dits roamed land routes, eager to kill mer­chants and steal their wares. The sea trade was daunt­ing: ships were flim­sy, nav­i­ga­tion was rudi­men­ta­ry, pirates abound­ed, and dan­ger­ous weath­er sank many ships. Yet, goods con­tin­ued to move, dri­ven by the immense prof­its to be made by bartering.

Camels, Incense and Pax Islamica

Dur­ing the late Pleis­tocene era, end­ing 10,000 years ago, a land bridge called Beringia (now the area of the Bering Strait) exist­ed tem­porar­i­ly between the east­ern and west­ern hemi­spheres. As a result, plant and ani­mal species moved between the Old and the New Worlds. Humans moved west to the New World, and camels and hors­es moved east into the Old World.

“One of the ear­li­est com­modi­ties trad­ed by boat must have been obsid­i­an, a black vol­canic rock (actu­al­ly a glass) that is a favorite of land­scap­ers and gar­den­ers worldwide.”

Because camels can store water effi­cient­ly through­out their bod­ies, they can go days or weeks with­out drink­ing. Plus, camels sweat less – that is, lose less of their stored water – than oth­er ani­mals, mak­ing them ide­al­ly suit­ed for life in arid regions. These hardy crea­tures quick­ly became the pri­ma­ry beasts of bur­den for trans­port­ing goods through­out Asia, includ­ing the Ara­bi­an deserts. Mer­chants also used don­keys, but the inde­fati­ga­ble camel did most of the work. One camel dri­ver with three to six drom­e­daries could move two tons of car­go some 20 to 60 miles dai­ly. Ini­tial­ly, traders trans­port­ed only the most valu­able goods: incense, per­fumes and body oils – pre­cious items dur­ing an era when peo­ple wore the same clothes repeat­ed­ly and sel­dom bathed, a time when pub­lic sew­er­age was either nonex­is­tent or exceed­ing­ly rank and rudi­men­ta­ry. Along with silk, frank­in­cense and myrrh were the most trea­sured goods.

“How did goods get from Chi­na to Rome? Very slow­ly and very per­ilous­ly, one labo­ri­ous step at a time.”

Muham­mad, the prophet of Islam, was born into a desert tribe of traders. His suc­ces­sor as Mus­lim ruler, Abu Bakr, was a cloth mer­chant. With its ear­ly roots in trad­ing, Islam has always respect­ed the move­ment and sale of mer­chan­dise. The Quran teach­es, “Do not devour your prop­er­ty among your­selves false­ly, except that it be trad­ing by your mutu­al con­sent.” Ear­ly Mus­lims were not per­mit­ted to steal from their co-reli­gion­ists, but steal­ing from infi­dels was a dif­fer­ent mat­ter. Thus, many Mus­lims became fear­some desert raiders.

“The advent of the writ­ten word around 3300 B.C. lift­ed his­to­ry’s cur­tain and revealed an already well-estab­lished pat­tern of long-dis­tance trade.”

Islam quick­ly became dom­i­nant through­out much of the known world. Mus­lims con­trolled the vital car­a­van routes, which meant they com­mand­ed most.

Extend­ed com­merce. Mus­lim fleets dom­i­nat­ed the oceans as Mus­lim plun­der­ers gov­erned the land. After the pass­ing of Muham­mad in 632, Islam emerged as the pri­ma­ry eco­nom­ic and social influ­ence. They endured a peri­od of peace and sta­bil­i­ty under Islam­ic rule until the 11th cen­tu­ry, when Chris­tians reclaimed ter­ri­to­ries in Spain and oth­er parts of south­ern Europe, coin­cid­ing with the First Cru­sade. Nonethe­less, Mus­lim mer­chants remained the prin­ci­pal force in long-dis­tance busi­ness until the 16th cen­tu­ry and, in numer­ous regions, well into the mod­ern era.

“Through­out record­ed his­to­ry, the main man­u­fac­tured trade com­mod­i­ty was fabric.”

In ancient eras, con­sis­tent trade occurred between Chi­na and regions to the west, encom­pass­ing Ara­bia and Europe. Islam reached deeply into Chi­na before the sev­enth cen­tu­ry. Mus­lim mer­chants, par­tic­u­lar­ly Per­sians, active­ly engaged in com­merce with the Chi­nese. They tra­versed the ancient Silk Road, as did Euro­pean traders. The Chi­nese orga­nized exten­sive sea­far­ing expe­di­tions for trea­sure voy­ages to India, Java, Suma­tra, and lat­er to the East African coast.

Maritime Routes and “Choke Points”

Mar­itime trade was so vital in the ancient world that ear­ly Greek pow­ers fierce­ly bat­tled each oth­er to con­trol the sea routes and the Helle­spont and Bosporus, two “naval choke points.” Due to their soils’ restrict­ed fer­til­i­ty, Greek city-states had to trade olive oil and wine for import­ed wheat and bar­ley to sur­vive. Athens aspired to become the lead­ing Greek city-state to con­trol essen­tial grain ship­ments. Athens and Spar­ta fought for dom­i­nance over the nar­row water­ways and, con­se­quent­ly, all traf­fic between the Black Sea and the Aegean. The Athe­ni­ans ulti­mate­ly emerged as a sig­nif­i­cant mar­itime force, estab­lish­ing the for­mi­da­ble Athen­ian Empire. How­ev­er, Spar­ta rose again to con­quer Athens and impose humil­i­at­ing peace terms. Years lat­er, Athens regained strength once more. When Alexan­der the Great assumed pow­er, he grant­ed Greek ships the free­dom to trans­port goods over the nav­i­ga­ble waters under his control.

“Although the pri­ma­ry pur­pose of the cru­sades was not com­mer­cial (unless one was Venet­ian or Genoese), Chris­tians rec­og­nized the Mus­lim con­trol of the spice trade for the lucra­tive oppor­tu­ni­ty it was.”

Between the 14th and 17th cen­turies, spices such as cin­na­mon, cloves, nut­meg, pep­per, and oth­ers replaced incense and per­fumes as the most pre­cious long-dis­tance trade com­modi­ties. Spices were trans­port­ed via the Silk Road, the Per­sian Gulf, and the Red Sea. By the 16th cen­tu­ry, the Por­tuguese dom­i­nat­ed sea trade with Asia, fol­lowed by the Genoese, Vene­tians, and, sub­se­quent­ly, the Dutch. Dis­tant trade brought numer­ous ben­e­fits to most involved, from afflu­ent indi­vid­u­als who donned splen­did Chi­nese silks and per­fumed the air around them with sweet-smelling incense to nations such as the Greeks, who relied entire­ly on import­ed grains for sus­te­nance. How­ev­er, ancient trade routes also trans­mit­ted fatal dis­eases, includ­ing the dev­as­tat­ing Black Death, a plague inad­ver­tent­ly car­ried from the Asian steppes to Europe and the East, where it may have claimed the lives of as many as a hun­dred mil­lion peo­ple in the 1300s.

Exploration of the New World

In the late 1400s, Genoese nav­i­ga­tor Christo­pher Colum­bus sought fund­ing from the Span­ish monar­chy for his west­ward voy­age to reach the leg­endary mar­kets in Chi­na and India. Most edu­cat­ed indi­vid­u­als, includ­ing Colum­bus, believed the world was round by this time. Nonethe­less, King Fer­di­nand and Queen Isabel­la ini­tial­ly reject­ed his pro­posed expe­di­tion, con­sid­er­ing it exces­sive­ly ardu­ous and treach­er­ous. Even­tu­al­ly, they com­mis­sioned his ven­ture. The rest, as they say, is his­to­ry. In 1492, Colum­bus and his three ships reached the New World. Dur­ing the same peri­od, Por­tuguese explor­er Vas­co da Gama com­plet­ed a voy­age of 28,000 miles around the world with a small fleet, spend­ing 95 days away from land. These were unimag­in­able achieve­ments at the time, and sub­se­quent­ly, glob­al trade and com­merce would nev­er be the same.

“By the ear­ly 17th cen­tu­ry, all paths led to the Nether­lands [which] assem­bled the first gen­uine­ly glob­al trad­ing system.”

As mariners and mer­chant adven­tur­ers embarked on remark­able and thrilling voy­ages of dis­cov­ery, paving the way for the exploita­tion of the New World for their gain and to enrich the cof­fers of their wealthy spon­sors, glob­al com­merce rapid­ly assumed entire­ly new dimen­sions. The exchange of plant species between the Old and New Worlds, notably corn and cof­fee, dra­mat­i­cal­ly trans­formed glob­al agriculture.

“The great nation­al trade orga­ni­za­tions, par­tic­u­lar­ly the Eng­lish and Dutch East India com­pa­nies, spear­head­ed Europe’s com­mer­cial dom­i­nance and made world trade the near­ly exclu­sive province of large cor­po­rate entities.”

The oceans also con­tin­ued to serve as con­duits for dis­ease. Con­quis­ta­dor Hernán Cortés intro­duced small­pox to the New World in the 1500s. His Span­ish sailors were immune to it, but it swift­ly dec­i­mat­ed mil­lions of Aztecs. Oth­er infec­tious dis­eases also tra­versed the trade routes, often with dread­ful results, but the most com­mon out­come of mar­itime trade and explo­ration was prof­it. For this rea­son, the traf­fick­ing of enslaved peo­ple bur­geoned. From the ear­ly 1500s to the abo­li­tion of slav­ery in the U.S. in the 1860s, 9.5 mil­lion enslaved Africans were trans­port­ed to the New World. The slave trade for­ev­er altered soci­ety and reshaped glob­al trade.

“Although free trade ben­e­fits human­i­ty, it also cre­ates losers who can­not be expect­ed to accept the new order passively.”

By the ear­ly 1600s, Dutch and Span­ish naval experts had com­pre­hen­sive­ly mapped Earth­’s wind cur­rents, mak­ing sea voy­ages more acces­si­ble and more fore­see­able. Enor­mous sil­ver reserves in Mex­i­co and Peru spurred the devel­op­ment of a glob­al mon­e­tary sys­tem. The Span­ish eight-real coin became the pri­ma­ry cur­ren­cy. Large cor­po­ra­tions emerged and expe­di­tious­ly assumed con­trol over inter­na­tion­al com­merce. With new, more afford­able pro­duc­tion and labor, numer­ous ser­vice work­ers, farm­ers, and tex­tile man­u­fac­tur­ers found their work no longer eco­nom­i­cal­ly viable.

A Shrinking World

As the world became more acces­si­ble and “small­er,” glob­al com­merce under­went rad­i­cal trans­for­ma­tions. Fol­low­ing 1700, farm­ers in numer­ous loca­tions could cul­ti­vate valu­able New World crops such as cot­ton, sug­ar, cof­fee, and tea, once a Chi­nese spe­cial­ty. By the 1700s, cot­ton grew in pop­u­lar­i­ty over Chi­nese silk. These devel­op­ments altered glob­al trade dynam­ics. The 1800s wit­nessed sig­nif­i­cant advance­ments in trans­porta­tion and com­mu­ni­ca­tion, includ­ing rail­ways, steamships, refrig­er­a­tion tech­niques, and steel man­u­fac­tur­ing improve­ments. Pro­duc­ers were pre­sent­ed with many new meth­ods for trans­port­ing goods over longer dis­tances at swifter speeds and a more con­ve­nient cost. Fur­ther­more, buy­ers and sell­ers could com­mu­ni­cate almost instant­ly thanks to the tele­graph. These advance­ments con­sid­er­ably pro­pelled world commerce.

Free Trade

From the 1400s onward, Eng­land imple­ment­ed var­i­ous laws impos­ing tar­iffs on corn. These “Corn Laws” grad­u­al­ly fad­ed into obscu­ri­ty, and few paid atten­tion to them until 1756, when the start of the Sev­en Years’ War led to dwin­dling grain sup­plies. Sub­se­quent­ly, the nation’s agri­cul­tur­al trade pol­i­cy swift­ly became con­tentious, insti­gat­ing riots to protest grain short­ages. This nation­al con­cern soon extend­ed to oth­er prod­ucts, par­tic­u­lar­ly cot­ton fab­ric, but debates regard­ing how to levy fees on imports and enhance exports per­sist on an inter­na­tion­al scale even today.

“When goods are not allowed to cross bor­ders, sol­diers will.” [ – Frédéric Bastiat]

The U.S., a vast land with exten­sive domes­tic mar­kets, embraced pro­tec­tion­ist mea­sures by impos­ing high import tax­es. Tra­di­tion­al­ly, Repub­li­cans advo­cate pro­tec­tion­ism, while Democ­rats are gen­er­al­ly less enthu­si­as­tic about it. The 1930 Smoot-Haw­ley Tar­iff, “one of the most noto­ri­ous pieces of leg­is­la­tion ever passed by Con­gress,” ele­vat­ed already steep U.S. import tar­iffs, pro­vok­ing oth­er nations to raise their tar­iffs sig­nif­i­cant­ly. Con­se­quent­ly, inter­na­tion­al com­merce near­ly ground to a halt in the ear­ly 1930s. Cordell Hull, sec­re­tary of state under Pres­i­dent Franklin Roo­sevelt, uti­lized his for­mi­da­ble pow­ers of per­sua­sion to cham­pi­on free trade. Thanks to him, Con­gress passed the Rec­i­p­ro­cal Trade Agree­ments Act in 1934, open­ing up the U.S. mar­ket. Inter­na­tion­al trade thrived at an astound­ing aver­age annu­al rate of 6.4% for the sub­se­quent 50 years.

“Glob­al­iza­tion, it turns out, was not one event or even a sequence of events; it is a process that has been slow­ly evolv­ing for a very long time.”

Free trade great­ly ben­e­fits numer­ous indi­vid­u­als world­wide. A 2006 study demon­strat­ed that the aver­age GDP amount­ed to $17,521 in nations with open trade poli­cies, while coun­tries with con­sis­tent­ly closed trade poli­cies only achieved an aver­age GDP of $2,362. Free trade oper­ates like any zero-sum game: some emerge vic­to­ri­ous, while oth­ers lose. Your fate hinges on whether your prod­uct can be man­u­fac­tured more afford­ably else­where. If so, peo­ple world­wide will pur­chase it and enhance their lives, but you may soon find your­self unem­ployed. Attempt­ing to reverse this effect resem­bles hold­ing back the tide with a broom. Ulti­mate­ly, this is glob­al­iza­tion: a blend of tri­umphs and set­backs, where the tal­ly is main­tained in terms of dis­tance and currency.
