Hi I’m John Green and this is Crash Course European History.

00:02

So we’re going to turn our attention now to the Industrial Revolution, one of the most

00:07

significant developments in human history.

00:10

Like, imagine with me that it’s 1820.

00:13

I got this idea from the economist Robert Gordon by the way.

00:16

You live in, say, England.

00:18

You probably work in agriculture.

00:20

When you walk to town, you’re either pulling your own cart, or if you’re lucky you have

00:25

a horse.

00:26

You have no running water or electricity.

00:28

When you wash your few items of clothing, you do so by hand.

00:32

You cook over a fire.

00:34

You think of time not primarily in minutes and hours, but mostly in relationship to solar

00:40

cycles--how close it is to night, or to morning, or to midwinter.

00:44

And in all these respects, your life in 1820 is basically identical to the lives of people

00:50

in 1720, or 1520, or for that matter 1220.

00:55

That’s not to say life hasn’t changed in those hundreds of years--as we’ve explored

01:00

in this series, lots has changed--but as Gregory Clark observed, in terms of standard of living,

01:07

Europeans in 1800 basically led lives similar to those of Neandrathals.

01:12

Now imagine that you close your eyes in 1820 and wake up in 1920.

01:18

By now, most people in England do not work in agriculture.

01:21

They may work in shops, or transportation, or mining, oe workshops, or in factories.

01:27

They measure time in minutes.

01:29

Cars exist.

01:30

Some people have radios, which transmitted information through thin air.

01:35

A few people even have refrigerators, which dramatically decrease food spoilage and the

01:40

risk of foodborne illness.

01:42

Occasionally you might even see an airplane flying in the sky.

01:47

Oh, and also, your country has just emerged from an astonishingly deadly war fought with

01:52

highly lethal weapons such as chlorine gas, weapons that people of 1820 could not possibly

01:58

have imagined.

02:00

Welcome to the Industrial Revolution.

02:06

[Intro] In this series, we’ve already talked about

02:13

revolutions in agriculture that increased European productivity and revolutions in trade

02:18

that increasingly distributed goods among people in towns and cities instead of having

02:23

each individual family produce everything it needed.

02:27

And these forces combined to help create more division of labor: like, farmers could focus

02:32

on farming, and textile workers could focus on textile creation, which was more efficient

02:38

than having each family do every kind of work.

02:41

So let’s begin in the eighteenth century, when European industrial production is said

02:45

to have begun.

02:47

Europe’s population was growing after centuries of non-stop wars, plagues, and the worst of

02:52

the little ice age.

02:54

Meanwhile, products such as coffee, tea, and chocolate made with heated water killed bacteria,

03:00

while products from abroad expanded and varied the pool of nutrients, with corn and potatoes,

03:06

for instance, generally more calorie-dense per acre than wheat.

03:10

In short, lives were getting longer and populations rising.

03:14

This meant that on average people had a little more time to learn, tinker, and experiment.

03:21

Many different artisans invented small improvements to existing mechanical devices.

03:26

Perhaps most famously, John Kay’s flying shuttle increased the pace and productivity
