Hi there my name's John Green; this is Crash Course World History.
And today we're going to talk about the Dark Ages,
possibly the most egregious Eurocentrism in all of history, which is really saying something.
(We're Europe! The Prime Meridian Runs Through us; We're in the Middle of Every Map;
and We Get To Be a Continent Even Though Were Not a Continent.)
But let's begin today with a pop quiz:
What was the best year of your life? And what was the worst year?
Mr. Green, Mr. Green: Best 1994, Worst 1990.
Oh, me from the past. It gets so much better, and also so much worse.
For worst year I'm gonna go with 2001; best year 2006.
Alright now it's your turn, dear pupils: share your best and worst years in comments during the intro.
Right, so what you will quickly find is that your worst year was someone else's best.
So, too, with history.
The period between 600 and 1450 CE is often called the Middle Ages in Europe.
Because it came between the Roman Empire—assuming you forget the Byzantines—and the beginning of the Modern Age.
And it's sometimes called the Dark Ages, because it was purportedly unenlightened.
But was the age so dark?
Depends on what you find depressing.
If you like cities and great poetry, then the Dark Ages were indeed pretty dark in Europe.
But if like me your two favorite things are Not Dying From Wars and not dying from anything
And meanwhile, outside of Europe,
Let's go to the Thought Bubble.
Medieval Europe had less trade, fewer cities, and less cultural output than the Original
London and Paris were fetid firetraps with none of the planning of sewage management
But with fewer powerful governments,
Anyway, people in Medieval Times lived slightly longer—
Instead of centralized governments,
The lords were also vassals to more important lords,
Below the knights were peasants
Feudalism was also an economic system,
The small scale, local nature of the feudal system was perfect for a time and place where
But of course,
and they almost never left their villages.
Thanks, Thought Bubble.
One more point that's very interesting from a world history perspective:
this devolution from empire to localism has happened in lots of places at lots of different
And in times of extreme political stress,
like after the fall of the Han dynasty in China,
power tends to flow into the hands of local lords who can protect the peasants better
than the state can.
We hear about this a lot in Chinese history and also in contemporary Afghanistan,
but instead of being called feudal lords, these landlords are called warlords.
Eurocentrism striking again.
The other reason the Dark Ages are called Dark
is because Europe was dominated by superstition
and by boring religious debates about like how many angels can fit on the head of a pin.
And while there's something to that,
the Middle Ages also saw theologians like Thomas Aquinas,
who was quite an important philosopher,
And women like Hildegard of Bilgen,
who wrote all this important liturgical music and also basically invented the genre of the
morality play.
All that noted,
things were certainly brighter in the Islamic world,
or Dar al Islam.
So when we last left the Muslims,
they had expanded out of their homeland in Arabia and conquered the rich Egyptian provinces
of the Byzantines and the entire Sassanian empire,
all in the space of about 100 years.
The Umayyad Dynasty then expanded the empire west to Spain and moved the capital to Damascus,
because it was closer to the action, empire-wise
but still in Arabia.
That was really important to the Umayyads
because they'd established this hierarchy in the empire with Arabs like themselves at
the top and in fact
they tried to keep Arabs from fraternizing with non-Arab muslims throughout the Empire.
This of course annoyed the non-Arab Muslims,
who were like,
“I don't know if you're reading the same Quran we are, but this one says that
we're all supposed to be equal.”
And pretty quickly the majority of Muslims weren't Arabs,
which made it pretty easy for them to overthrow the Umayyads,
which they did in 750 CE.
Their replacements, the Abb(ah)sids, Abb(uh)sids?
Hold On...
D'ahh, I'm right twice!
so the Abbasids were from the Abb(ah)si or the Abb(uh)-see family
which hailed from the Eastern and therefore more Persian provinces of the Islamic Empire.
The Abbasids took over in 750 and no one could fully defeat them—
until 1258, when they were conquered by—
wait for it—
the Mongols.
The Abbasids kept the idea of a hereditary monarchy,
but they moved the capital of the empire to Baghdad,
and they were much more welcoming of other non-Arab Muslims into positions of power.
And under the Abbasids,
the Dar al Islam took on a distinctly Persian cast that it never really lost.
The Caliph now styled himself as a king of kings,
just like the Achaemenids had,
and pretty soon the caliph's rule was a lot more indirect,
just like the original Persians'.
This meant that his control was much weaker,
and by about 1000CE , the Islamic Caliphate which looks so incredibly impressive on a
map had really descended into a series of smaller kingdoms,
each paying lip-service to the caliph in Baghdad.
This was partly because the Islamic Empire relied more and more on soldiers from the
in this case Turks,
and also slaves pressed into military service, in order to be the backbone of their army,
a strategy that has been tried over and over again and has worked exactly zero times.
Which you should remember if you ever become an emperor.
Actually our resident historian points out that that strategy has worked--
if you are the Mongols.
More important than the Persian-style monarchy that the Abbasids tried to set up was their
openness to foreigners and their ideas.
That tolerance and curiosity ushered in a golden age of Islamic learning centered in
The Abbasids oversaw an efflorescence of culture unlike anything that had been seen since Hellenistic
Arabic replaced Greek not only as the language of commerce and religion,
but also of culture.
Philosophy, medicine, and poetry were all written in Arabic
(although Persian remained an important literary language.)
And Baghdad was the world's center of scholarship with its House of Wisdom and immense library.
Muslim scholars translated the works of the Greek Philosophers including Aristotle and
as well as scientific works by Hippocrates, Archimedes
and especially the physician Galen.
And they translated and preserved Buddhist and Hindu manuscripts that might have otherwise
been lost.
Muslims made huge strides in medicine as well.
One Muslim scholar ibn Sina, wrote the Canon of Medicine,
which became the standard medical textbook or centuries in both Europe and the Middle
And the Islamic empire adopted mathematical concepts from India
such as the zero, a number so fascinating and beautiful
that we could write an entire episode about it but instead
I'm just gonna write it a little love poem:
Oh, zero.
Pretty little zero.
They say you're nothing but you mean everything to mathematical history
....and me.
Oh it's time for the Open Letter?
[Scoots to chartreuse throne of pure velvety awesomeness]
An Open Letter to Science and Religion:
But first lets see what's in the Secret Compartment.
Oh, champagne poppers?
Stan, what am I supposed to do with these?
Dear Science and Religion,
You're supposed to be so irreconcilable and everything,
but not so much in the Abbasid Empire.
I mean,
Muslim mathematicians expanded math to such a degree
that we now call the base ten number system
and the symbols we use to denote it “Arabic numerals.”
And religion was at least part of what pushed all that learning forward.
Like the great philosopher Ibn Rushd argued that
the only path to religious enlightenment was through Aristotelian reasoning.
And Muslim mathematicians and astronomers developed algebra
partly so they could simplify Islamic inheritance law.
Plus they made important strides in trigonometry
so that people understand where to turn
when trying to turn toward Mecca.
You were working so well together, science and religion,
but then like Al and Tipper Gore, just couldn't last forever.
Nothing gold can stay in this world, nothing gold can stay.
Best wishes, John Green
Baghdad wasn't the only center of learning in the Islamic world.
In Spain, Islamic Cordoba became a center for the arts,
especially architecture.
This is perhaps best exemplified by the Great Mosque at Cordoba,
built by the Umayyad ruler Abd al-Rahman I In 785-786 CE.
That's right, this building,
still standing today and one of the most amazing mosques in the world,
was built in a year,
whereas medieval cathedrals typically took, like,
a million years to finish.
The Muslims of Spain were also engineers who rivaled the Romans.
Aqueducts in Cordoba brought drinkable water into the city,
and Muslim scholars took the lead in agricultural science,
improving yields on all kinds of new crops,
allowing Spanish lives to be longer and less hungry.
Everybody wanted to live in Spain,
even the greatest Jewish philosopher, Maimonides,
wanted to live in Spain, but sadly he was expelled
and ended up in Alexandria Egypt.
There he wrote his awesomely titled defense of rationality,
A Guide for the Perplexed.
I'm translating the title, of course, because the original text was written
…in Arabic.
Meanwhile, China was having a Golden Age of its own:
The Tang Dynasty made China's government more of a meritocracy,
and ruled over 80 million people across four million square miles.
And they might've conquered all of Central Asia
had it not been for the Abbasids, whom they fought at
the most important Battle You've Never Heard Of,
the Battle of the Talas River.
This was the Ali-Frasier of the 8th century.
The Abbasids won, which ended up defining who had influence where with the --
with the Abbasids dominating to the west of the river and China dominating to the east.
The Tang also produced incredible art that was traded all throughout Asia.
Many of the more famous sculptures from the Tang Dynasty feature figures who are distinctly
which again demonstrates the diversity of the empire.
The Tang was also a golden age for Chinese poetry
with notables like Du Fu and Li Bo plying their craft,
encouraged by the official government.
And the Song Dynasty, which lasted from 960 to 1258,
kicked even more ass-it's-not-cursing-if-you're-talking-about-donkeys.
By the 11th century,
Chinese metalworkers were producing as much iron
as Europe would be able to produce in the 18th century.
Some of this iron was put to use in new plows,
which enabled agriculture to boom,
thereby supporting population growth.
Porcelain was of such high quality that it was shipped throughout the world,
which is why we call it “china.”
And there was so much trade going on that the Chinese ran out of metal for coins,
leading to another innovation–
paper money.
And by the 11th century, the Chinese were writing down recipes for
a mixture of saltpeter, sulfur and charcoal,
that we now know as gunpowder.
That becomes kind of a big deal in history,
paving the way, as it does,
for modern warfare and arena rock pyrotechnics, and—
ohhhh, THAT'S WHY.
[Pulls Champagne popper along with a mysterious lady hand from behind chalkboard.]
Not so dark after all.
