Hi, I’m John Green, and this is Crash Course World History.
Let’s begin today with a question.
Why am I alive? Also, why don’t I have any eyes? Ah, That’s better.
The way we answer that question ends up organizing all kinds of other thoughts, like what we
should value, and how we should behave, and if we should eat meat, and whether we should
dump that boy who is very nice, but insanely clingy, in a way that he cannot possibly think
is attractive. All of which adds up-
Uh, Mr. Green, Mr. Green, uh, are you talking about me?
Yes, I’m talking about you, me from the past. I’m telling you that one of the reasons
we study history is so that you can be a less terrible boyfriend, but more on that momentarily.

Today we’re going to talk about civilizations, but in order to do that, we have to talk about
talking about civilizations, because it’s a problematic word. So problematic, in fact,
that I have to turn to camera 2 to discuss it.
Certain Conglomerations of humans are seen as civilizations, whereas, say, nomadic cultures
generally aren’t, unless, you are -- say it with me --
the mongols
By calling some groups civilizations, you imply that all other social orders are uncivilized,
which is basically just another way of saying that they’re savages or barbarians.
side note: originally Greek, the word Barbarian denoted anyone who did not speak ancient Greek,
because to the Greeks, all other languages sounded like bar bar bar bar bar bar.
So, that is to say that we are all essentially barbarians, except for the classics majors,
which is worth remembering when we’re discussing civilizations.
Civilizations are like most of the things we like to study, they’re intellectual constructs.
No one woke up in the city of Thebe’s in Egypt one morning and said, “what a beautiful
morning, I sure am living at the height of Egyptian civilization.” Still, they’re
useful constructs, particularly when you’re comparing one civilization to another. They’re
less useful when you’re comparing a civilization to a non-civilization type social order, which
is why we will try to avoid that.
And yes, I am getting to the good boyfriend stuff. Patience, grasshopper.
So what is a civilization? Well, diagnosing a civilization is a little like like diagnosing
an illness. If you have four or more of the following symptoms, you might be a civilization.
Surplus production. Once one person can make enough food to feed several people, it becomes
possible to build a city, another symptom of civilization.
It also leads to the specialization of labor, which in turn leads to trade. Like, if everybody
picks berries for a living, there’s no reason to trade, because I have berries, and you
have berries, but if I pick berries for a living and you make hammers, suddenly, we have cause to trade.
Civilizations are also usually associated with social stratification, centralized government,
shared values, generally in the form of religion, and writing. And at least in the early days,
they were almost always associated with rivers.
These days you can just bisect a segment of land horizontally and vertically, and boom,
build a city. But 5000 years ago, civilizations were almost always associated with rivers. Whether
that’s the Tigris and Euphrates, the Yellow River, The Nile, the Amazon Basin, the Coatzacoalcos -
Gaaah! I was doing so good until I got to Coatzacoalcos!
(computer says: Coatzacoalcos) Coatzacoalcos. Maybe.
Why river valleys? They’re flat, they’re well watered, and when they flood, they deposit nutrient-rich silt.
We’ll have more to say about most of these civilizations later, but let’s talk about
this guy, the Indus Valley Civilization, ‘cause it’s my all time favorite.
The Indus Valley Civilization was located in the flood plain of the Indus and Sarawati
rivers, and it was about the best place in the world to have an ancient civilization
because the rivers flooded very reliably twice a year, which meant that it had the most available
calories per acre of pretty much anywhere on the planet.
We know the Indus Valley Civilization flourished a long time ago. Probably around 3000 BCE.
Why is that question literally hanging over my head?
But people of the Indus valley were trading with Mesopotamians as early as 3500 BCE. We also
know that it was the largest of the ancient civilizations. Archaeologists have discovered more than 1500 sites.
So what do we know about this civilization? Let’s go to the Thought Bubble.
Everything we know about the Indus Valley Civilization comes from archaeology, because
while they did use written language, we don’t know how to read it, and no Rosetta Stone
has thus appeared to help us learn it.
I meant the other Rosetta Stone, Thought Bubble, yeah.
Although, come to think of it, either would be acceptable.
So here’s what we know, they had amazing cities. Harappa and Mohenjo Daro are the best
known, with dense, multi-story homes constructed out of uniformly sized bricks along perpendicular
streets. I mean this wasn’t some ancient world version of Houston, more like Chicago.
This means they must have had some form of government and zoning, but we don’t know
what gave this government its authority.
Cities were oriented to catch the wind and provide a natural form of air conditioning.
And they were clean. Most homes were connected to a centralized drainage system that used
gravity to carry waste and water out of the city in big sewer ditches that ran under the
main avenues, a plumbing system that would have been the envy of many 18th century European cities.
Also, in Mohenjo Daro, the largest public building was not a temple or a palace, but
a public bath, which historians call the Great Bath. We don’t know what the great bath
was used for, but since later Indian culture placed a huge emphasis on ritual purity, which
is the basis for the caste system, some historians have speculated that the bath might
have been like a giant baptismal pool.
Also, they traded. One of the coolest things that the Indus Valley Civilization produced
were seals used as identification markers on goods and clay tablets. These seals contained the writing
that we still can’t decipher, and a number of fantastic designs, many featuring animals and monsters.
One of the most famous and frightening is of a man with what looks like water buffalo
horns on his head, sitting cross-legged between a tiger and a bull. We don’t know what’s
really going on here, but it’s safe to say that this was a powerful dude, because he
seems to be able to control the tiger.
How do these seals let us know that they traded? Well, because we found them in Mesopotamia,
not the indus valley. Plus, archaeologists have found stuff like bronze in the indus
valley that is not native to the region. So what did they trade? Cotton cloth. Still such
a fascinating export, incidentally that it will be the subject of the 40th and final
video in this very series.
But here’s the most amazing thing about the Indus Valley people. They were peaceful. Despite
archaeologists finding 1500 sites, they have found very little evidence of warfare, almost no weapons.
Thanks Thought Bubble. OK, before we talk about the fascinating demise of the Indus
Valley Civilization. It’s time for the open letter.
Magic!
I wonder what the secret compartment has for me today? Oh! Fancy clothes.
I guess the secret compartment didn’t think I was dressed up enough for the occasion.
An open letter to Historians. Dear historians, the Great Bath? Really? THE GREAT BATH? I’m
trying to make history fascinating, and you give me a term that evokes scented candles,
bath salts and Frederic Fekkai hair products?
I know sometimes the crushingly boring names of history aren’t your fault. You didn’t
name the federalist papers or the Austro-Hungarian Empire or Adam Smith. But when you do get
a chance to name something, you go with THE GREAT BATH? Not the Epic Bath of Mohenjo Daro,
or the Bath to End All Baths, or the Pool That Ruled, or the Moist Mystery of Mohenjo
Daro or the Wet Wonder? The Great Bath? Really? You can do better. best wishes, John Green.
So what happened to these people? Well, here’s what didn’t happen to them. They didn’t
morph into the current residents of that area of the world, Hindu Indians or Muslim Pakistanis.
Those people probably came from the Caucasus.
Instead, sometime around 1750 BCE, the Indus Valley Civilization declined until it faded
into obscurity. Why? Historians have three theories.
One: Conquest! Turns out to be a terrible military strategy not to have any weapons, and it’s possible
people from the Indus Valley were completely overrun by people from the Caucasus.
Two: Environmental Disaster! It’s possible they brought about their own end by destroying their environment.
Three: Earthquake! The most interesting theory is that a massive earthquake changed the
course of the rivers so much that a lot of the tributaries dried up.
Without adequate water supplies for irrigation, the cities couldn’t sustain themselves,
so people literally picked up and headed for greener pastures.
Well, probably not pastures, it’s unlikely they became nomads. They probably just moved
to a different plain an continued their agricultural ways. I am already boring you and I haven’t
even told you yet how to be a better boyfriend and/or girlfriend. I’m going to do that now.
So we don’t know why the Indus Valley Civilization ended, but we also don’t really know why
it started. Why did these people build cities, and dig swimming pools, and make unnecessarily ornate seals?
Were they motivated by hunger, fear, a desire for companionship, the need to be near their
sacred spaces, or a general feeling that city life was just more awesome than foraging?
Thinking about what motivated them to structure their life as they did helps us to think about
how we structure our own lives. In short, you’re clingy because you’re motivated
by fear and a need for companionship,
and she finds it annoying because it’s enough work having to be responsible for herself
without having to also be responsible for you.
Also, you’re not really helping her by clinging, and from the Indus Valley in the bronze age,
to school life today, human life is all about collaboration.
Trading cloth for bronze, building cities together, and collaborating to make sure that
human lives are tilted to catch the wind.
Next week we will travel here to discuss the Hot Mess o’ Potamia, but in the meantime,
if you have any questions, leave them in comments, and our team of semi-trained semi-professionals
will do their best to answer them.
Also, you’ll find some suggested resources in the video info below, he said, pointing
at his pants. Thanks for watching, and we’ll see you next week!
