Today, I'm going to give you a very broad overview of human history.

Future continuous

I'll be using the latest version of my Timeline of World History chart, which is available as a poster from my website, usefulcharts.com in particular, I'm going to be showing you how history can be divided into various time periods or ages.

And I'll be explaining how these divisions end up highlighting some of the most important turning points in world history.

Let me start by explaining the basics of how this chart works.

The vertical scale represents the flow of time with time moving forward.

As you move down the page, every white line represents 100 years.

And the scale is equidistant, which means that the distance between two lines near the top of the chart is exactly the same as it is near the bottom.

This is important because it allows for accurate comparisons to be made and thus gives the viewer a proper perspective on time.

Horizontally, the various sections of the chart represent different parts of the world.

So on the far left, we have the Americas, followed by Africa, Europe, Asia, and

Every line on the chart represents a specific culture, civilization or empire.

And the width of the line represents the relative importance of that culture when compared to other cultures from the same time period or region.

The next thing we need to talk about are the terms AD and BC and their equivalents, CE and BCE AD means Anno Domini, which is Latin for in the year of the Lord.

Basically, it's meant to measure the years from the birth of Jesus.

Anything before that point is called bc, which stands for before Christ.

Now, most scholars today have actually concluded that Jesus was probably born in 4 BC so keep in mind that the scale is a bit off.

So as we move backwards through time, the AD dates go down, but

then once we get to bc, the dates start going back up.

And I should point out that there is no year zero.

So basically, the year 1bc was followed immediately by the year 1ad nowadays, it's becoming more and more standard for historians to use the terms CE and BCE instead.

CE stands for common era and BCE stands for before the common era.

The reason for the change is simply an attempt to use a more neutral term.

Which makes sense considering that 75% of the world is not Christian.

Okay, now that we've got that under our belt, the next question we need to address is, what is the starting point for history?

In other words, where do we draw the line between history and prehistory?

Well, on this chart, I've used the year 3300 BCE as my starting point.

The reason for this is that this is approximately when writing first appeared.

The basic idea is that without written records, we can't have history.

Therefore, everything before the emergence of the first writing systems is best categorized as prehistory.

And of course, prehistory goes back much farther than 5,300 years.

If we're talking about the prehistory of our species, Homo sapiens, it goes back about another 200,000 years.

Another a time period also known as the Stone Age.

And if we're talking about the prehistory of the planet Earth, well, that goes back about 4.5 billion years.

Instead, it starts with the emergence of written records and goes from there.

So, on this chart, history is divided into six main time periods.

The Early Bronze Age, the Bronze Age, the Iron Age, Classical Antiquity, the Middle Ages, and

Let's now take a look at each one by one.

The Bronze Age gets its name based on the fact that humans first started to make things out of bronze around the same time that they first developed writing.

This occurred in three main Egypt, Sumer, which is modern day Iraq, and

Unfortunately, the writing system used in the Indus Valley is yet to be deciphered, so we can only read the records from Egypt and Sumer.

But we do know that these three civilizations did trade with one another, and

that throughout the early Bronze Age, each grew in terms of both size and technology.

At the start of this period, the Sumerians had already invented the wheel, the plough, and the sailor.

But during the early Bronze Age, they also went on to develop astronomy and mathematics.

Over in Egypt, it was during the early Bronze Age that the great pyramids of Giza were built.

Besides these three civilizations, the only other place in the world to have large cities was over in what is today Peru.

There, a culture known as the Norte Chico civilization was thriving.

But strangely, although they built large stone structures, they appear to have had no writing system and no pottery.

Stone structures dating from the Early Bronze Age can also be found at Stonehenge in England and on the island of Malta.

But neither of these places had large populations.

Dividing these two time periods is a very important event known as the 4.2 kiloyear event, named because it occurred approximately 4.2 thousand years ago.

The exact cause of the event is still debated, but

what we do know is that it resulted in approximately 100 years of extremely dry conditions worldwide.

Because of this, the Egyptian Old Kingdom, the Akkadian Empire, which had conquered Sumer, and

the Indus Valley civilization all declined rapidly.

And in the time period that followed, we get a new set of cultures.

Egypt was revived as the Middle and New Kingdoms, and

the Sumerian civilization eventually evolved into the Babylonian civilization.

But in South Asia, we get a more dramatic change.

The Indus Valley cities disappear altogether and we get a new set of people arriving, the Indo Aryans, who were part of the larger Indo European group during the Bronze Age proper.

We also get civilizations arising in other parts of the world for the first time, including in China, Sub Saharan Africa, and

unbeknownst to many people, North America.

There we get the poverty Point culture, where large mounds and complex settlements were built.

Finally, we also get the first civilization in Europe, the Minoans, on the island of Crete.

Midway through the period, though, there was a volcanic eruption nearby which led to the downfall of the Minoans and the rise of the Mycenaean Greeks.

Instead, this catastrophe could very well have been the event that birthed the Atlantis myth.

The next big turning point in history occurred around 1200 BCE, and

For reasons that are still somewhat unclear.

The major civilizations in Greece, Anatolia and Egypt all disappeared almost instantaneously.

What followed is often called the Greek Dark Ages, a period in which the historical record for the region goes somewhat silent.

Interestingly, it is during this silent period that many of the world's most famous legendary tales supposedly took place, such as those found in the Jewish Torah, the Greek Iliad and the Hindu Mahabharata.

The Bronze Age collapse also coincided with the first use of iron in the Middle East.

Therefore, the period in which the Greek Dark Ages took place is also aptly called the Iron Age.

This is the third and final period in what is known as the Three Age system, consisting of the Stone Age, the Bronze Age and the Iron Age.

The next period is not actually part of the three age system.

This is because after approximately 600 BCE, we no longer have to rely entirely on archaeology to get information.

As I mentioned earlier, humans have been writing since 3300 BCE.

But there is nothing surviving from the Bronze Age or Iron Age that could really be considered a history book.

Sure, we have the names of kings, lists of battles, and

other details carved into rock and metal, but

we don't have anything that starts with, in this treatise, I am going to record the complete history of X.

But around this time, we do start to get such writings, for example, from a Greek guy named Herodotus, who is often called the father of history.

So in other words, we know a heck of a lot more information about this next period called Classical Antiquity than we know about the previous periods.

Classical Antiquity is when the Greeks and the Romans laid the foundations for what would become known as Western civilization, mostly by borrowing and building upon information gained from the earlier Bronze Age civilizations.

But there was a lot going on in other parts of the world as well.

For example, in Mesoamerica, Olmec culture would go on to influence classical Mayan culture, which with its intricate calendar and writing system.

And in North America, there was an extensive trade network where lots of different types of art was being exchanged.

In Africa, the long standing kingdom of Kush eventually gave way to the kingdom of Aksum in Ethiopia.

There was also the three mighty Persian empires, the Maurya and Gupta empires in India, and

Eventually, a trade route between all these areas opened up, known as the Silk Road.

And thus the western parts of Eurasia and the eastern parts of Eurasia were connected for the first time.
