hey and welcome back to heimler's history now we've been going through unit 1 of the ap u.s history curriculum and in the last video i talked about spanish colonialism in the americas and ended by mentioning the colombian exchange and in this video that's what i'm about to split up so let's get to it okay so the colombian exchange what is it so glad you asked the colombian exchange was the transfer of food animals minerals people and diseases between africa europe and the americas and i know what you're thinking so what but this was a really big deal because this exchange fundamentally transformed the societies and the economies and the environments of all three of the continents that i just mentioned and i think you're going to start to see it as we start talking about it and just for poops and giggles let's start with the transfer of disease in the last video we considered what happened when the spanish first showed up in the americas but it did not take long for them to embark on a campaign to conquer the americas and remake them in their own image but here's the conundrum recall that tenochtitlan the capital of the aztec or the mexican empire had somewhere between two hundred thousand and four hundred thousand inhabitants when the spanish conquistador hernan cortez showed up he had just over a thousand men with him most of which were allies he had made with another group of native peoples and yet in short order tenochtitlan fell to cortes and his forces now you don't have to be that good of a military strategist to realize that something is very strange here how did one thousand people conquer hundreds of thousands of people and the simple answer is disease most notably smallpox and when the spanish showed up with this deadly disease it ravaged the native peoples you see africans europeans and asians they all had contact with one another for like millennia and therefore had been exposed to each other's nasty germs and had built up some immunity but the americas have been completely isolated from such germs and the people there for had no immunity and i'm not overstating it when i say that the disease part of the colombian exchange fundamentally altered society in the americas for example when the spanish landed on the island of hispaniola they brought smallpox with them and the native arawak and taino peoples were devastated to the tune of about 300 000 dead it was the same with the incas in 1530 they had a population of about 9 million and a century later their population was 500 000 and the aztecs and the maya and all the surrounding regions had a combined 40 million people in 1530 but 150 years later they had a combined three million okay so you're starting to see that the colombian exchange was a big deal it absolutely was but it wasn't just disease that was exchanged so was food coming from the americas into europe you had high yielding nutritious foods like maize and tomatoes and potatoes and cacao and just for funsies tobacco which i know isn't food but you know whatever and europeans and africans sent food over to the americas like rice and wheat and soybeans and rye and oats and lemons and oranges and it was the grain crops especially that transformed the populations in the americas as it became a staple food item for them all right how about animals well the europeans introduced horses and pigs and cattle and chickens to the americas and pigs and cattle transformed the diet of native americans and horses revolutionized farming and warfare and another element of the exchange was minerals which is to say gold and silver and after the incan and aztec empires were conquered the spanish plundered them for their vast quantities of gold and silver and when those metric buttloads of money were sent back to the homeland it made spain wealthy beyond belief and frankly if it wasn't for this new source of wealth it's hard to say whether european colonizers would have kept returning i mean you know maybe they would but the silver and gold certainly made them sick with desire to return and not only did this wealth transform the americas by attracting large numbers of european colonizers but it also transformed europe itself as well starting a little after 1500 europe and more to the point western europe began experiencing unprecedented economic growth which had significant consequences for how their society functioned prior to this the social political and economic system of europe was largely defined by a system called feudalism which was a system where peasants lived and worked on the land of a noble in exchange for armed protection but this influx of wealth hastened the end of the system then what came to take its place was a form of capitalism which is an economic system based on private ownership in the free and open exchange of goods between property owners additionally people were transferred in the colombian exchange as well and starting with christopher columbus native americans were enslaved and taken back to spain and admittedly this was a relatively small transfer of people far more significant was the transfer of enslaved africans to the americas they were captured and sold on the african coast crammed into ships in astonishing numbers and then were made to endure the brutal middle passage across the atlantic ocean in which many of them died of disease and starvation before even arriving and when they did arrive they were sold into bondage to the highest bidder now we're going to talk a lot more about that in the next video so i'll leave it there at this point so i focused a lot on the spanish in this video only because they were the first to be in colonizing the americas but soon many western european nations will join the spanish in this new world colonization and participate in the colombian exchange but one more thing is worth mentioning and that's how the spanish finance all this exploration and how other colonizing nations would later innovate upon this the spanish colonization effort was driven by the state and specifically its mercantilist economic policies in case you don't know mercantilism was the dominant economic system of europe during this time and basically what you need to know about mercantilism is that it depended on heavy governmental direction and intervention later other nations would privatize exploration with a new model of funding namely joint stock companies we're gonna talk much more about that in unit two but i just wanted to mention it here by way of contrast all right
