The Columbian Exchange: Crash Course World History #23

In which John Green teaches you about the changes wrought by contact between the Old World and the New. John does this by exploring the totally awesome history book “The Columbian Exchange” by Alfred Crosby, Jr. After Columbus “discovered” the Americas, European conquerors, traders, and settlers brought all manner of changes to the formerly isolated continents. Disease and invasive plant and animal species remade the New World, usually in negative ways. While native people, plants, and animals were being displaced in the Americas, the rest of the world was benefitting from American imports, especially foods like maize, tomatoes, potatoes, pineapple, blueberries, sweet potatoes, and manioc. Was the Columbian Exchange a net positive? It’s debatable. So debate.

0.24 -> Hi. I’m John Green, this is Crash Course World History and today's video is kind of
4.15 -> a response to one of the most riveting history books you'll ever read, the Columbian Exchange
8.58 -> by David Crosby. He had a good year in 1969-- published The Columbian Exchange, played Woodstock,
13.339 -> he was still on his first liver. What? It was Albert Crosby? Gash! History, never being
17.98 -> as interesting as I want it to be.
19.38 -> Right, so it was Alfred Crosby Jr., and in that book he wrote, "The big questions are
22.49 -> really the only ones worth considering, and colossal nerve has always been a prerequisite
27.05 -> for such consideration." I love it!
29.539 -> Before 1492, we couldn't really talk about a world history at all, we could only talk
32.95 -> about the different histories of separate regions, but Columbus changed all of that,
37.52 -> and everything else. The Columbian Exchange irrevocably homogenized the world's biological
41.45 -> landscape. Since Columbus, the number of plant and animal species has continually diminished,
45.78 -> and the variation in species from place to place has diminished dramatically. I mean,
48.94 -> the first European visitors to the Americas had never seen a tomato or a catfish; Native
52.58 -> Americans had never seen a horse, and by making our planet biologically singular, the Columbian
57.17 -> Exchange completely remade the populations of animals, particularly humans. And vitally,
61.76 -> this cross-pollination also made possible such wonders as contemporary pizza.
65.92 -> [theme music]
74.72 -> So we're going to break the Columbian Exchange down into four categories: Diseases, boy,
78.79 -> you're looking good Smallpox, I'm glad you've been eliminated; Animals, Plants, and People.
82.61 -> Mr. Green, Mr. Green! People are animals.
84.88 -> Yeah, that's true, me from the past, but just for the sake of simplicity we're--
87.19 -> Also, when you think about it, microbes are kinda animals and plants are, too, I mean--
90.659 -> Oh my god, shut up before I kill you and create a time travel paradox.
93.87 -> Microbes, like those hairy blokes back there, were a definite negative in terms of the Columbian
98.89 -> Exchange. Terminology is hard here, but the majority of Caribbean Islanders or Native
102.09 -> Americans or Amerindians had exactly one response to the arrival of Europeans: death.
108.299 -> We can't be sure of how many natives died as a result of European arrival but it was
111.299 -> definitely more than 50% and some estimates place it as high as 90%. Historians used to
116.42 -> blame European brutality, which was definitely a factor, but the main culprit was disease.
121.69 -> Smallpox is usually seen as the villain of the story but it is more likely that a series
124.479 -> of diseases in combination did the damage. Along with smallpox, Americans were killed
128.259 -> by measles and mumps, typhus, chicken pox, none of which they had been previously exposed
133.349 -> to. This astonishing decrease of population was definitely the worst effect of these diseases,
138.329 -> both psychologically and demographically.
140.819 -> But the secondary effects were almost as bad. For one thing the deaths of Aztec and Incan
144.609 -> rulers touched off wars which made it easier to spread disease, because you know, the number
148.999 -> one way to catch smallpox is via hand-to-hand combat. Plus leaders kept dying. Huayna Capac,
153.779 -> the leader of the Incan empire, succumbed to smallpox before Pizarro even arrived. His
158.23 -> death led to a violent succession struggle between his sons which was won by Atahualpa,
161.599 -> who in turn was captured and killed by Pizarro. And without that war, the Inca would have
165.639 -> had a much better chance against the Spaniards, whose numbers were comparatively tiny. A similar
169.499 -> thing happened to the Aztecs. The Moctezuma who eventually lost to Cortés was the nephew
173.34 -> of a much more powerful king who died of smallpox. And the death of that great king encouraged
178.01 -> some of the smaller states in the Aztec empire to rebel, and some of them even fought for the Spaniards.
182.48 -> And another effect of disease was starvation, because there simply weren't enough people
186.29 -> left to grow crops to feed the living. And the malnutrition made survivors that much
190.169 -> more susceptible to disease. In short, it sucked.
193.359 -> The transmission of disease largely went one way, from the Old World to the New, but the
197.68 -> Americans did have one gift for Europe: venereal syphilis. It showed up in Europe around 1493,
203.849 -> and even though Europeans are very fond of ascribing syphilis to each other: Italians
207.519 -> called it the French disease; the French called it the disease of Naples; Poles called it
211.419 -> the German disease; Russians called it the Polish disease. The truth is, venereal syphilis
215.549 -> was spread by sailors who'd returned from the Americas.
217.909 -> In fact, in his book, The Columbian Exchange, Crosby tells it like this: "Sailors, by the
221.62 -> nature of their profession, are men without women and therefore men of many women. We
226.559 -> can imagine no group more perfectly suited for guaranteeing that venereal syphilis would
230.62 -> have worldwide distribution." Who says history books are boring? Syphilis would go on to
234.769 -> infect a veritable who's who of Europe: from Baudelaire to Gauguin to Nietzsche, not to
238.959 -> mention numerous family members of the famously infertile Tudor and Valois families, meaning
243.949 -> that syphilis may be responsible for many of those miserably boring dynastic power struggles
248.459 -> of post-Columbus Europe. Anyway, nothing against syphilis, but it pales in comparison to the
252.219 -> devastation wrought by Old World diseases arriving in the New World.
255.579 -> But the New World did have one gift for the Old World that was pretty destructive: tobacco.
260.359 -> Oh, it's time for the open letter and there's been a costume change? That doesn't bode well.
268.22 -> An Open Letter to Tobacco.
269.69 -> But first let's see what's in the secret compartment don't be cinnamon don't be cinnamon don't
272.99 -> be -- dang it!
274.259 -> I guess that I'm going to do the cinnamon challenge. Oh, I am not happy about this Stan,
284.2 -> for the record -- alright, I'm going to do the cinnamon challenge: one tablespoon of
290.039 -> cinnamon in my mouth, no water.
302.64 -> Huh, boy, that -- that sucked. I, I uh regret r-regret doing that to be honest with you.
308.05 -> Dear Tobacco, I just did something really stupid but at
310.479 -> least it was cheap. I'm gonna tell you two stories about smoking, the first come from
313.629 -> my high school history teacher Raoul Meyer who also writes Crash Course. When I was a
317.34 -> senior in high school he walked up to me and he said, "I want you to keep smoking. I want
321.659 -> you to smoke until the day after your 65th birthday, and then I want you to die so that
326.71 -> I collect all of your social security." That inspired me, Mr. Meyer, to quit smoking just eight short years later.
332.08 -> Here is an amazing statistic: cigarettes were handed out to American servicemen during World
336.129 -> War II and more soldiers who started smoking during the war died from smoking than died from the war.
342.689 -> So if the New World was looking to extract some measure of revenge for smallpox, and
346.74 -> measles, and chicken pox: Mission accomplished.
349.22 -> Best Wishes, John Green
350.74 -> Now onto animals. American animals, like llamas and guinea pigs, never really caught on in
355.31 -> Eurasia. But imports to the Americas, like pigs, cows and horses were revolutionary.
360.59 -> Let's go to the thought bubble:
361.84 -> First of all, these animals, especially pigs, completely remade the food supply. Pigs breed
366.43 -> really quickly, they eat anything and they turn into bacon, which made them heroes to
371.37 -> the new world just as today they are heroes to the internet. Here's how quickly pigs breed:
375.83 -> When Hernando de Soto arrived in Florida in 1539, he brought 13 pigs. By the time of his
381.759 -> death, there were 700 - that was 3 years later. The abundance of meat and plentiful land for
387.34 -> agriculture and grazing meant that Europeans in the Americas very rarely experienced famine,
392.21 -> and despite what you may have learned about religious and political freedom, the main
395.84 -> reason Europeans came to America was to eat.
399.65 -> Large European animals also changed the nature of work in the Americas. Before Europeans,
403.319 -> the largest beast of burden was the llama, and at best it could carry like, 100 lbs.
407.84 -> This meant that for the long distance travel that the Inca engaged in, the primary transportation
412.569 -> animal was Incas. Oxen, when combined with their plows, made it possible to bring more
417.77 -> land under cultivation and also made transportation easier and more efficient, and plus European
422.879 -> animals remade culture.
424.639 -> The grossly stereotypical American Indian, like from the movies, riding the Great Plains
429.06 -> with an eagle feather headdress and war paint, well he didn't exist before the Columbian
434.099 -> Exchange because there were no horses for him to ride. And the introduction of horses
437.99 -> allowed many Native Americans to abandon agriculture in favor of a nomadic lifestyle because riding
442.539 -> around hunting buffalo made them far richer than farming ever had. Thanks Thought Bubble.
446.96 -> While animals and diseases completely reshaped the New World, it was New World plants that
451.34 -> had the biggest effect on Eurasia.
453.03 -> Sure, Europeans brought over some crops that we now grow here in the Americas like wheat
457.06 -> and grapes, both of which are necessary for Catholic mass, but New World plants radically
461.259 -> changed the lives of millions, maybe hundreds of millions of Africans, Asians and Europeans,
466.62 -> specifically by making pizza possible.
469.199 -> [Heavenly singing, "It was the greatest gift of all."]
475.289 -> I mean until 500 years ago Italians lived without tomatoes, without modern pizza or
480.259 -> marinara sauce or pizza or ketchup or pizza or even pizza. Indians lived without curry,
486.949 -> which contains chilies, a New World food. Persians lived without corn, which is a New
490.889 -> World food, as are beans and potatoes and avocados and peanuts and blueberries - the
495.569 -> list goes on and on.
496.759 -> And these New World crops led to probably the greatest population increase in history.
500.31 -> To quote Crosby, "It is crudely true that if man's caloric intake is sufficient, he
504.8 -> will somehow stagger to maturity, and he will reproduce."
508.61 -> And New World food was far more caloric than Old World food, which is the central reason
512.32 -> that the world population doubled between 1650 and 1850. Plants like corn and potatoes
517.69 -> could grow in soils that were useless for Old World crops. Potatoes were actually introduced
521.72 -> to Europe as an aphrodisiac, but it turns out that you have to distill those potatoes
525.19 -> into vodka before they have the desired effect. Anyway, if potatoes are an aphrodisiac, the
529.1 -> Irish quickly became the hottest people on Earth.
531.38 -> An acre and a half of potato cultivation could feed an Irish family for a year, and the average
535.77 -> Irish worker often ate 10 lbs. of potatoes every day. Surviving primarily on potatoes,
542.56 -> the Irish more than doubled their population between 1754 and 1845, when the Potato Famine
547.94 -> showed up and ruined everything.
549.44 -> And it wasn't just Europe. Manioc, or cassava is a New World plant with roots that provide
553.23 -> more calories than any other plant on Earth, provided they are properly processed (otherwise
558.14 -> they're poisonous). Manioc is so prevalent in Africa that many Africans swear that the
561.81 -> plant is native to the continent, but it isn't.
563.58 -> Nor are sweet potatoes, and while New World grains never replaced rice in Southeast, or
567.33 -> East Asia, the sweet potato was so common that it is known as the "poor person’s staple"
570.78 -> in China. Even in Japan, the tomb of the farmer who is reputed to have first brought them
574.5 -> to the islands is known as the Temple of the Sweet Potato. And it's also worth noting that
578.29 -> corn, while it may not feature prominently in European diets, has been the central source
581.93 -> of food for animals in Europe for centuries.
584.36 -> And in fact, that's still the case. In 2005, 58% of the corn grown in America went to animal
590.01 -> feed (is the kind of thing you learn when you live in Indiana).
592.16 -> Alright, so last but not least, the Columbian exchange involved the transfer of lots of
595.45 -> people. Again, in the early stages this movement was mostly one way, with Europeans and Africans
600.26 -> - the Africans usually against their will - making their way to the Americas.
603.42 -> So the Columbian Exchange led to the re-population of the New World following the disease devastation
607.39 -> of the initial encounter. And better nutrition allowed the population of the Old World to
610.53 -> grow which in turn placed population pressure on Eurasia which led to more people coming
614.48 -> to the Americas. In the process, the world's human inhabitants became more genetically
618.06 -> and ethnically interconnected. But it also led to the horrors of Atlantic slavery, which
621.71 -> we'll be discussing next week.
622.87 -> What are we to make of the Columbian Exchange? It devastated the population of the Americas,
626.58 -> it led to the widespread slavery of Africans, but it also allowed for a worldwide population
630.58 -> increase and the lives of some Natives including Plains tribes like the Lakota became better
634.64 -> and more secure, at least for a while.
636.95 -> Fewer people have starved since the Columbian Exchange began, but the diversity of life on
640.14 -> Earth has diminished dramatically and planting crops where they don't belong has hurt the environment.
644.65 -> So on the whole, should we be grateful for the Columbian Exchange? And should we work
647.97 -> to continue and deepen its legacy of globalism and monoculture?
651.44 -> Crosby didn't think we were better off. "The Columbian Exchange has included man, and he
655.41 -> has changed the Old and New Worlds sometimes inadvertently, sometimes intentionally, often
659.97 -> brutally. It is possible that he and the plants and animals he brings with him have caused
664.92 -> the extinction of more species of life forms in the last four hundred years than the usual
669.62 -> processes of evolution might kill off in a million... The Columbian Exchange has left
673.94 -> us with not a richer but a more impoverished genetic pool. We, all of the life on the planet,
679.23 -> are the less for Columbus, and the impoverishment will increase."
682.74 -> But let's give you the last word today: Do you agree with Crosby? Are longer, healthier
686.6 -> lives for more humans worth the sacrifice of an impoverished biosphere? And most importantly,
691.33 -> how will your conclusions about those questions shape the way that you live your life?
695.42 -> Thanks for watching. I'll see you next week.
697 -> Crash Course is produced and directed by Stan Muller. Our script supervisor is Danica Johnson.
700.6 -> The show is written by my high school history teacher, Raoul Meyer, and myself, and our
703.94 -> graphics team is Thought Bubble.
705.5 -> Last week’s phrase of the week was "Mario and Luigi,” thanks for that suggestion.
708.63 -> If you want to suggest future phrases of the week you can do so in comments or you can
711.75 -> also guess at this week’s phrase of the week, and ask questions about today's video
714.94 -> that will be answered by our team of historians. Thanks for watching Crash Course, and as we
718.33 -> say in my hometown, Don't Forget To Be Awesome.
