Crash Course: The Modern Revolution
Crash Course: The Modern Revolution
As civilizations grew larger, demand for resources grew along with it. This led people to spread out over larger territories in search of food, natural resources, and new ideas.
As this video progresses, key ideas will be introduced to invoke discussion.
Think about the following questions as you watch the video
Why did European explorations to other areas of the work mark a significant change to collective learning and why did these explorations begin in the mid- to late-fifteenth century
The connection of the four world zones was immediately profitable for Europeans and for us but what were some of the negative effects?
How is the Industrial Revolution the result of years of collective learning?
How did the Industrial Revolution spark a different kind of adaptive radiation?
Why did industrialization begin in Great Britain and not in some other part of the world?
: Hi, I'm John Green.
: Welcome toCrash Course Big History.
: Today we're going to look at the modern revolution.
: Mr. Green, Mr. Green!
: But what does modern even mean?
: I mean, I know that fax machines
: and Super Nintendo are modern, but, like, people used to think
: that toilets that flushed were modern.
: That's actually a pretty perceptive question,
: me from the past.
: So, if we're going to talk about modernity,
: we should probably define modernity.
: But first, I have great news.
: There is a future me from the past
: where video games are so much better than Super Nintendo.
: In fact, this machine plays 24,000 games
: and it's in the office of future you.
: What were we talking about?
: Oh, right, modernity.
: So, some historians date the beginning of the modern era
: with the beginnings of the Industrial Revolution
: in the 19th century.
: Some date it to the French Revolution in 1789.
: Some push it further back
: to 16th and 17th century European colonialism.
: And some date modernity with the European Renaissance
: and call anything past the year 1500 "early modern."
: But through aBig Historylens, all of these are just signs
: of acceleration in human collective learning,
: which was already underway and took its first tiny steps
: in East Africa 250,000 years ago.
: Then again, it would be silly
: to call the first human foragers "early-early-early modern."
: So for the purposes of today, let's say:
: With an acknowledgment that it's all a little bit arbitrary.
: And I know what you're wondering,
: but no, 1750 was several decades
: before the first flushing toilets.
: So last week, we looked at how collective learning--
: which relies on population numbers and connectivity
: to produce new ideas-- grew by leaps and bounds
: with the introduction of agriculture.
: By the year 1400, the human population
: had advanced magnificently, but the world was still divided
: into four isolated world zones: the Americas, Australasia,
: the Pacific, and Afro-Eurasia.
: From aBig Historyperspective,
: what makes the European explorations worthy
: of a place in an episode called "Modern Revolution"
: is that they eventually united all four world zones
: into a global system.
: But why did the Europeans feel so motivated to expand?
: Well, a lot of reasons.
: One, Ottoman dominance of overland trade routes with Asia,
: particularly after the conquest of Constantinople in 1453,
: made Europeans seek alternative routes to the populace
: and rich lands of the East.
: Two, European states were fairly small compared to some
: of the vast empires of Asia and needed to compete
: for more resources to fuel their almost-constant wars.
: And three, the fruits of exploration
: undoubtedly had positive effects,
: whether it be the many advanced inventions
: and consumer goods imported from China
: or the spices of India and Indonesia,
: or crops from the Americas.
: That last one should not be underestimated.
: Crops like the potato-- which earned the nickname
: "ready-made bread" because it was easy to prepare--
: combined with maize and squashes and tomatoes
: and various yams allowed farms in Europe
: to support more people.
: This was also good for Asia,
: where those crops were introduced in the 17th century.
: And let us not forget about the vast amounts of silver
: that the Spanish "acquired" from the Americas
: or the many cotton, tobacco, and sugar farms
: that Europeans bolstered their economies with.
: The unification of the world zones
: also had many, many negative effects.
: For instance, it was terrible for people who worked
: on those cotton and tobacco and sugar farms.
: Europeans increasingly relied on African slaves,
: the first of whom were granted to the Portuguese
: by African rulers, and then, you know, several centuries
: of horror ensued with an incomprehensible number
: of African slaves dying in the appalling conditions
: of the Atlantic crossing.
: Life was also pretty miserable
: for the slaves that survived the journey
: and generations of their descendents.
: Also, because Afro-Eurasia was a modestly connected
: thriving cesspool of disease,
: Europeans had developed many immunities.
: When they started arriving in the previously isolated Americas
: in the late 1400s and 1500s, the indigenous inhabitants
: had no immunity to those diseases.
: This resulted in one of the most horrific events
: in human history.
: A cocktail of various European diseases, most notably smallpox,
: killed off an estimated 50 million people
: in the Americas in little over a century.
: A similar tragedy played itself out in Australia
: when Europeans started arriving there in the 18th century.
: Now, along with all this horrific stuff,
: the unification of the world zones was, nevertheless,
: a good thing for collective learning,
: which would eventually prove our salvation in many ways.
: Which is why people can now look at this on their smart phone.
: Anyway, the unification of the world zones did not
: in itself lead to a breakthrough
: in the way humans harvested matter and energy.
: The last major shift happened with the arrival
: of agriculture 10,000 years prior.
: The colonizing European societies of the 16th, 17th,
: and 18th centuries remained agrarian.
: But the explorations did allow for a network of exchange
: that eventually did lead to a major breakthrough
: in how humans harnessed more energy and produced more
: and more cultural complexity:
: The Industrial Revolution began in Great Britain,
: as they'll be happy to tell you, in the 18th century.
: But it was a global revolution involving collective learning
: shared across the global system.
: But a number of innovations that kickstarted industry
: originated in Britain, like the more intensified use
: of steam engines or the use of coke to refine metal.
: Not that Coke-- yeah, that coke.
: Also, they invented many textile machines
: and Britain had lots of coal and it was relatively easy to mine.
: Thank you, trees that died hundreds
: of millions of years ago.
: We're going to turn you into industry.
: And smog.
: But all those British breakthroughs
: wouldn't have been possible without a huge global network
: of trade that supplied raw materials like cotton
: and that opened new markets
: where Britain could sell its goods.
: And it wouldn't have been possible to expand that network
: of trade in the first place without gun powder
: and the compass, which both came from China.
: The methods of porcelain manufacture
: that were important to the Industrial Revolution
: in Britain also came from China via Germany.
: And the improved methods of farming,
: which freed up many British farm workers
: for industrial wage labor in the cities came
: from Flanders in the Netherlands.
: Early designs for steam engines came from 18th century France,
: and much of the designs for these machines depended
: on mathematics preserved and transmitted
: by Islamic and Hindu civilizations.
: So up until the end of the 18th century,
: virtually all production in human history was propelled
: by human or animal muscle power, or else by wind and water power.
: But it turned out the coal and oil had stored energy
: from the sun that had built up over hundreds
: of millions of years.
: And using those resources dramatically increased
: the energy that humans could harness.
: Huge numbers of goods could be produced by factories
: at relatively low prices which meant that over many decades,
: goods that had previously been seen as luxuries
: by common people were suddenly viewed as necessities.
: By the 1900s, most Europeans enjoyed a standard
: of living higher than the kings of the Middle Ages.
: Coal and oil also allowed mechanization of agriculture,
: which raised the carrying capacity,
: increasing the population.
: And new modes of connectivity beginning with the telegraph,
: and then later, the telephone,
: increasingly bound the human species together,
: allowing for swift and rapid exchange of ideas.
: For 250,000 years, if I wanted to tell someone
: who lived 100 miles away from me something,
: it took me days to do so.
: For the last 100 years, it's taken me seconds.
: Because a slight tweak in modes of production
: in the 18th century and the adoption
: of fossil fuels lead to an explosion
: of productivity and invention in the 1800s and 1900s,
: people often compare the Industrial Revolution
: to the Cambrian explosion about 540 million years ago.
: Remember:
: In the Cambrian explosion, that evolutionary change
: was biological.
: In the Industrial Revolution, that increased pace
: of change was cultural.
: Consider bike design.
: In the 1800s, there were many, many different designs
: for bikes, some of which look amazingly, terrifyingly unsafe.
: In the beginning of innovations for bicycles,
: a huge number of designs filled all of the available niches.
: Eventually, those designs started competing
: with each other and a few forms won out.
: You've got the road bike and the mountain bike and the BMX bike.
: Just a little bit different variations of the same thing.
: Another example is the adaptive radiation of electronics.
: Take a look at all the stuff you needed in the 1980s
: to do what your average cell phone can do today.
: And that was only a few decades ago.
: Many new ideas sparked an increase in the human standard
: of living and the complexity of societies
: in tons of different ways.
: The explosion of cultural evolution
: that started 200 years ago has yet to cease.
: The Cambrian explosion went on for millions of years.
: The Agricultural Revolution proceeded
: for thousands of years.
: We're still right in the middle of the modern revolution--
: maybe only at the beginning.
: The huge shift in human activity and a rise
: in complexity may continue
: long after our grandchildren's lifetimes.
: That is, so long as we don't do something stupid,
: which, you know, withhomo sapiens,
: is always a distinct possibility.
: And let's not forget about the rise in complexity
: that's been happening since the beginning
: of the universe 13.8 billion years ago.
: A star is essentially a pile of hydrogen and helium.
: It's extremely simple.
: By comparison, a brain that arose via biological evolution
: is an intricate network of billions of connections
: and building blocks.
: Industrial society is an immense whirring global network
: of millions upon millions of brains more closely connected
: than ever before.
: The products of this society raised complexity even further.
: Bottom line is this, if the first part of this series,
: which looked at the vastness of the universe,
: made you feel insignificant, just remember that now
: at the tremendous heights of technological progress,
: humanity is, in terms of networks and building blocks:
: And there's currently no end to the potential
: for rising complexity in sight.
: This brings us to a long-standing
: historical question:
: why did the Industrial Revolution happen in Britain?
: Great Britain was certainly uncommonly well positioned.
: That said, so was China.
: So why didn't the Industrial Revolution happen
: in, say, Song Dynasty China
: between the 10th and 13th centuries?
: So, we know:
: And China has had both for a long time.
: The medieval Chinese had much more advanced
: agricultural methods than Europe.
: They paid attention to weeding and growing crops
: in rows and frequently used tools like the seed drill.
: And they were doing it all centuries
: before that stuff was even heard of in Europe.
: In the 900s, the spread of wet rice farming
: in southern China raised the carrying capacity even further
: because rice fields simply produce more food.
: They are more efficient.
: Also, rice is easier to prepare
: than the laborious European process
: of turning wheat into bread.
: So during the 10th and 11th centuries,
: the Chinese population increased from about 50 or 60 million
: to about 120 million.
: That's a lot of new innovators.
: So many, in fact, that Song China came close
: to having a modern revolution of its own.
: I mean, coal was used to manufacture iron.
: Production increased from 19,000 metric tons per year
: around 900 CE to 113,000 metric tons by 1200 CE.
: The Song Dynasty was the first to invent and harness the power
: of gunpowder, and then later in the 15th century,
: Zheng He conducted overseas explorations decades
: before Columbus.
: Textile production showed the first ever signs
: of mechanization in ways similar to the European spinning jenny.
: But China had dry coal while the British
: needed to pump water out of their coal mines
: in order to mine coal, which led the British
: to build steam engines.
: So why didn't the modern revolution start
: in China around 1000 CE?
: Well, it might have been the cultural and political climate
: and the shift away from innovation and commerce
: at the end of Song China in 1279.
: Possibly because they hadn't united the world zones
: in a network of trade and unified collective learning.
: And possibly because the right combination
: of cultural innovations required
: to launch a Cambrian-style explosion
: of growth just didn't happen.
: The point is that collective learning
: is such a powerful force that,
: from the explosion of the world population
: from only six million people 10,000 years ago
: to the 954 million by the end of the Agrarian Era,
: the right combination of ideas that lead
: to the industrial explosion
: might have happened almost anywhere.
: So long as there are brains to think and exchange ideas,
: so long as there are energy flows on the earth...
: The modern revolution was accompanied
: by explosive growth in human population.
: It took 250,000 years for humanity
: to achieve its first billion people.
: By 1900, the world's population was 1.6 billion.
: Today there are over 7 billion potential innovators
: who are now connected by the lightning speed of the internet,
: and collective learning is more powerful than ever.
: Humans now have unprecedented control
: and power over the Earth's biosphere
: which has prompted some scientists and scholars
: to claim that the Holocene is over
: and we now stand on the threshold of a new era,
: the Anthropocene.
: During this age, we may continue to raise complexity
: in our little pocket of the universe to wondrous new levels,
: hopefully to the growing benefit of all humans
: rather than just a privileged few.
: Thanks to collective learning, our potential is awesome.
: Unless, that is, we hit a wall,
: like agrarian societies did every few centuries
: when their population growth outstripped their rates
: of agricultural innovation.
: We are now in an era of immense danger
: where the modern global system of humanity
: might exhaust the resources of the earth
: in the same way that agricultural societies
: often exhausted the resources of the field.
