Coal, Steam, and The Industrial Revolution: Crash Course World History #32

August 12, 2019

Hi, I’m John Green; this is Crash Course
World History, and today we’re going to discuss the series of events that made it
possible for you to watch Crash Course. And also made this studio possible. And made the
warehouse containing the studio possible. A warehouse, by the way, that houses stuff
for warehouses. That’s right, it’s time to talk about the Industrial Revolution. Although it occurred around the same time
as the French, American, Latin American, and Haitian Revolutions – between, say, 1750 and
1850 – the industrial revolution was really the most revolutionary of the bunch. Past John: No way, dude. All those other revolutions
resulted in, like, new borders and flags and stuff. Present John: [sigh] We’ve studied 15,000
years of history here at Crash Course, Me from the Past. And borders and flags have
changed plenty, and they’re going to keep changing. But in all that time, nothing much changed
about the way we disposed of waste or located drinking water or acquired clothing. Most people lived
on or very close to the land that provided their food. Except for a few exceptions, life expectancy
never rose above 35 or below 25. Education was a privilege, not a right. In all those
millennia, we never developed a weapon that could kill more than a couple dozen people
at once, or a way to travel faster than horseback. For 15,000 years, most humans never owned
or used a single item made outside of their communities. Simon Bolivar didn’t change that and
neither did the American Declaration of Independence. You have electricity? Industrial Revolution.
Blueberries in February? Industrial Revolution. You live somewhere other than a farm? Industrial
Revolution. You drive a car? Industrial Revolution. You get twelve years of free, formal education?
Industrial Revolution. Your bed, your antibiotics, your toilet, your contraception, your tap
water, your every waking and sleeping second: Industrial Revolution. [theme music] Here’s one simple statistic that sums it
up: Before the industrial revolution, about 80% of the world’s population was engaged
in farming to keep itself and the other 20% of people from starving. Today, in the United States,
less than 1% of people list their occupation as farming. I mean, we’ve come so far that we don’t
even have to farm flowers anymore. Stan, are these real, by the way? I can’t tell if
they’re made out of foam or digital. So what happened? TECHNOLOGY! Here’s my definition: The Industrial Revolution was an increase
in production brought about by the use of machines and characterized by the use of new
energy sources. Although this will soon get more complicated, for our purposes today,
industrialization is NOT capitalism – although, as we will see next week, it is connected
to modern capitalism. And, the industrial revolution began around 1750 and it occurred
across most of the earth, but it started in Europe, especially Britain. What happened?
Well, let’s go to the Thought Bubble. The innovations of the Industrial Revolution
were intimately interconnected. Like, look, for instance, at the British textile industry:
The invention of the flying shuttle by John Kay in 1733 dramatically increased the speed
of weaving, which in turn created demand for yarn, which led to inventions like the Spinning
Jenny and the water frame. Soon these processes were mechanized using water power, until the
steam engine came along to make flying shuttles really fly in these huge cotton mills. The most successful steam engine was built
by Thomas “They Didn’t Name Anything After Me” Newcomen to clear water out of mines.
And because water was cleared out of those mines, there was more coal to power more steam
engines, which eventually led to the fancying up of the Newcomen Steam Engine by James “I
Got a Unit of Power and a University Named After Me” Watt, whose engine made possible
not only railroads and steamboats but also ever-more-efficient cotton mills. And, for the first time, chemicals other than
stale urine (I wish I was kidding) were being used to bleach the cloth that people wore
– the first of which was sulfuric acid, which was created in large quantities only thanks
to lead-lined chambers, which would’ve been impossible without lead production rising
dramatically right around 1750 in Britain, thanks to lead foundries powered by coal. And all these factors came together to make
more yarn that could be spun and bleached faster and cheaper than ever before, a process
that would eventually culminate in $18 Crash Course Mongols shirts. Available now at
Thanks, Thought Bubble, for that shameless promotion of our beautiful, high-quality t-shirts
available now at So, the problem here is that with industrialization
being so deeply interconnected, it’s really difficult to figure out why it happened in
Europe, especially Britain. And that question of why turns out to be one of the more contentious
discussions in world history today. For instance, here are some Eurocentric reasons
why industrialization might have happened first in Europe: There’s the cultural superiority
argument that basically holds that Europeans are just better and smarter than other people.
Sometimes this is formulated as Europeans possessing superior rationality. By the way,
you’ll never guess where the people who make this argument tend to come from – unless
you guessed that they come from Europe. And then, others argue that only Europe had
the culture of science and invention that made the creation of these revolutionary technologies
possible. Another argument is that freer political institutions encouraged innovation and strong
property rights created incentives for inventors. And, finally, people often cite Europe’s
small population because small populations require labor-saving inventions. Oh, it’s
time for the Open Letter? An Open Letter to the Steam Engine. But first,
let’s see what’s in the secret compartment today. Oh, it’s a TARDIS. Truly the apex
of British industrialization. Dear Steam Engine, You know what’s crazy?
You’ve really never been improved upon. Like this thing, which facilitates time travel,
probably runs on a steam engine. Almost all electricity around the world, whether it’s
from coal or nuclear power, is just a steam engine. It’s all still just water and heat, and
it speaks to how truly revolutionary the Industrial Revolution was that since then, it’s really
just been evolution. Best Wishes, John Green So, you may have heard any of those rationales
for European industrialization, or you may have heard others. The problem with all of
them, is that each time you think you’re at the root cause it turns out there’s a
cause of the root cause. To quote Leonardo DiCaprio, James Cameron, and coal mine operators,
“We have to go deeper.” But, anyway, the problem with these Eurocentric
why answers, is that they all apply to either China or India or both. And it’s really
important to note that in 1800, it was not clear that Europe was going to become the
world’s dominant manufacturing power in the next hundred years. At the time, China,
India, and Europe were all roughly at the same place in terms of industrial production. First, let’s look at China. It’s hard
to make the European cultural superiority argument because China had been recording
its history since before Confucius, and plus there was all that bronze and painting and
poetry. It’s also kind of difficult to make a blanket
statement that China was economically inferior to Europe, since they invented paper money
and led the world in exports of everything from silk to china. I mean, pre-Industrial
Revolution, population growth was the surest sign of economic success, and China had the
biggest population in the world. I guess that answers the question of whether they’re
digital. It’s also difficult to say that China lacked
a culture of invention when they invented gunpowder, and printing, and paper, and arguably
compasses. And China had more free enterprise during the Song dynasty than anywhere in the
world. Some argue that China couldn’t have free
enterprise because they had a long history of trying to impose monopolies on items like
salt and iron. And that’s true, but when it comes to enforcing those monopolies, they
also had a long history of failure. So really, in a lot of ways, China was at least as primed
for an Industrial Revolution as Britain was. So, why didn’t it happen? Well, Europeans
– specifically the British – had two huge advantages: First, Coal. When you trace the
story of improved transportation, or communication, or industrial efficiency, or better chemical
manufacturing, it always comes back to coal, because the Industrial Revolution was all about
using different forms of energy to automate production. And England had large supplies of coal that
were near the surface, which meant that it was cheap to mine, so it quickly replaced
wood for heating and cooking and stuff. So that encouraged the British to look for more
coal. The only problem with coal mining, aside from it being, you know, like, deadly and
everything, is that the coal mines flooded all the time. I guess coal mining is also
a little problematic for, like, the health of, you know, like, the planet. But, because there was all this incentive
to get more coal out of the ground, steam engines were invented to pump water out of
the mines. And because those early steam engines were super inefficient, they needed a cheap
and abundant source of fuel in order to work – namely, coal, which meant they were much
more useful to the British than anyone else. So steam engines used cheap British coal to
keep British coal cheap, and cheap British coal created the opportunity for everything
from railroads to steel, which like so much else in the Industrial Revolution, created
a positive feedback loop. Because they run on rails, railroads need steel. And because
it is rather heavy, steel needs railroads. Secondly, there were Wages. Britain (and to
a lesser extent the Low Countries) had the highest wages in the world at the beginning
of the 18th century. In 1725, wages in London were the equivalent of 11 grams of silver
per day. In Amsterdam, they were 9 grams. In Beijing, Venice, and Florence, they were
under 4. And in Delhi, they were under 2. It’s not totally clear why wages were so
high in Britain. Like, one argument is that the Black Death lowered population so much
that it tightened labor markets, but that doesn’t explain why wages remained low in,
like, plague-ravaged Italy. Mainly, high wages combined with cheap fuel costs meant that
it was economically efficient for manufacturers to look to machines as a way of lowering their
production costs. To quote the historian Robert Allen: “Wages were high and energy was cheap.
These prices led directly to the industrial revolution by giving firms strong incentives
to invent technologies that substituted capital and coal for labor.” Ugh, Stan, I’m a little worried that people
are still going to accuse me of Eurocentrism. Of course, other people will accuse me of
an anti-European bias. I don’t have a bias against Europe. I love Europe. Europe gave
me many of my favorite cheeses and cross-country skiing and Charlie Chaplin, who inspired today’s
Danica drawing. Like, the fact of coal being near the surface
in Britain can’t be chalked up to British cultural superiority. But the wages question
is a little different because it makes it sound like only Europeans were smart enough
to pay high wages. But here’s one last thing to consider: India
was the world’s largest producer of cotton textiles, despite paying basically the lowest
wages in the world. Indian agriculture was so productive that laborers could be supported
at a very low cost. And that, coupled with a large population, meant that Indian textile
manufacturing could be very productive without using machines, so they didn’t need to industrialize. But more importantly from our perspective,
there’s a strong argument to be made that Indian cotton production helped spur British
industrialization. It was cotton textiles that drove the early Industrial Revolution,
and the main reason that Britain was so eager to produce cottons was that demand was incredibly
high. They were more comfortable than woolens, but they were also cheaper, because cottons
could be imported from India at such a low cost. So, Indian cottons created the market and
then British manufacturers invested in machines (and imported Indian know-how) to increase
production so that they could compete with India. And that’s at least one way in which
European industrialization was truly a world phenomenon. For those of you who enjoy such
highly contentious and thorny, cultural historical debates, good news. Next week, we’ll be
talking about capitalism. Thanks for watching, I’ll see you then. Crash Course is produced and directed by Stan
Muller. Our script supervisor is Danica Johnson. The show is written by my high school history
teacher, Raoul Meyer, and myself. We are ably interned by Meredith Danko. And our graphics
team is Thought Bubble. Last week’s phrase of the week was “The
New England Revolution.” That was challenging. If you want to suggest future phrases of the
week or take a guess at this week’s, you can do so in comments, where you can also ask

    This video is misleading.

    This video overlooks most actual details of the Industrial revolution, and focuses more on the social aspect within the societies.

    Also, this video overlooks the fact that 1790-1850 was only the 1st phase of the Industrial Revolution.

    Then, this video fails to state that from 1850 to 1910, the most important phase, surpassed the 1st phase of industrialization in the United States of America by 300%.

    From 1850 to 1910, the United States became the largest industrial, and manufacturing base in the World, and surpassed Europe.

    At the risk of sounding judgmental of my own heritage; Is it possible that the rate of wages might have a direct correlation to the laziness of the people? After all, the intelligence required to figure out how to use coal is a far cry from inventing the astrolabe or compass. And from what historical accounts report; coal wasn’t mined initially to spur travel and other benefits that came from the industrial revolution, but to find a way to help people work less. While I’m definitely not complaining, is it possible that the industrial revolution was the lucky accident of laziness? 🙂

    I'm sure in the 4700 comments since this video went up 7 years ago, my thoughts have been echoed, but here you go. I love your series. I do. I get that it is de rigueur to spout nonsense about how "name the non-British place" was just as primed for the Industrial Revolution as any other. But, well, that's nonsense. And coal is a bit simplistic; it is not an especially rare resource.

    The revolutionary part of the Industrial Revolution is how it refashioned society. The Plague set the stage for this when a dramatic reduction in manpower sapped the wealth of aristocratic landowners. In the context of western European institutions, this set into motion the end of things like serfdom and the beginning of more pluralistic institutions. There is only one country in the 1700s that had all of the necessary ingredients: secure property rights, high labor costs, and a political system that allowed what we call "creative destruction." The industrial revolution couldn't have happened in, say, Austria or China because those countries were run by an elite that — correctly — saw industrialization as fundamentally destabilizing for the ruling powers and had the capacity to prevent the implementation of such new technologies.

    I feel like there was a lot here about the outcome and not much about the process… The industrial revolution completely reformed British society, as people gathered from the countryside to form huge cities in order to work in factories. This sudden and unprecedented change came with all sorts of problems, and working conditions were horrendous, but the new working order and lowered costs of mass produced items like bread and clothes, along with their newly available education, gave former peasants the chance to rise and create the middle class. The railway network that drastically altered Europe paved the wartime supply lines, while steamboats improved cross-atlantic trade: things which had great impact on the people's way of life.

    Those dense industrial cities still exist, although their trade wealth is gone, factories replaced by offices; the clustered red brick houses still stand; the canals run between them; Ireland still makes expensive linen, and until the 80s Wales still mined coal. Even the co-operative is still running banks, supermarkets and funeral care.

    Would you please not repeat the idea that life expectancy before the industrial revolution was 35 at best. My apologies if you’ve already clarified this in some other video, but that figure is misleading because it’s an average that takes into account infant mortality (which was very high). If you get eight people, and one lives a normal lifespan while the others all die before their first birthday, you could say that the average life expectancy for that group was very low— and that’s pretty much exactly what was going on before the agricultural revolution and the invention of modern medicine. And pretty much all times and places throughout history, anyone who reached adulthood could reasonably expect to live into at least their 60s.

    James Watt IMPROVED Newcomen’s steam engine. The first successful engine to drive locomotives worked by a different system perfected by Trevithick.

    The industrial revolution began in England specifically because it was a democracy and it was able to become a democracy because it rejected overarching superstition and religion. Its rulers were rational and as Adam Smith (a Scotsman) showed, understood the principles which guided progress. The famous “Invisible Hand”.
    In contrast the renaissance might have began in southern Europe but it was snuffed out by the Catholic religion which wouldn’t even accept that the Earth orbits the sun. Anyone who told the truth could be executed. The difference between Catholic countries and Protestant/free religion countries remains until this day.
    Similarly, the Chinese remained poor and backward until about 30 years ago(!!) because they were governed by superstition or Communism.
    India is still backward because (shush, speak quietly) their average IQ is only about 80 or 85. So despite a few bright areas, the odd rocket etc half the population still defecate in the open and millions raise families etc but without any living accommodation at all, simply living on the streets.
    Africa (average IQ 70) will never be able to prosper unless it hands government to others. Europeans or Far East Asian.
