Acient civilizations timeline

Farming starts in E.

5200 BCE

This is when Egypt started farming. This started before Egypt was a kingdom. When I use the loose term "farming" I mean the development of domesticated crops and animals. quatr.us/egypt/economy/farming.htm

S. is founded

5000 BCE

This is the time period of when Sumer in ancient mesopotamia was developed as a single nation. Before this Sumer was a small farming community in the fertile cresent. Sumer grew to be a large prominent city after more farming and agriculture technology was developed.

Y.R. civilization is founded

4000 BCE

This is the year when the Yelllow river civilization is estimated to be founded. It is later than the rest as it is the farthest away from Africa which is the supposed place of where humans started out. It may also be because only ten percent of the river is fertile for crops.

I. civilization is founded

4000 BCE

This is estimated to be the year that the Indus valley civilization became an ancient nation. This civilization is special as it developed its farming around the same time it developed itself. We do not know much about them as most ancint civilizations due to time or not understanding the language.

Farming starts in S.

4000 BCE

This is estimated to be the time when farming started in Sumer. Sumer is in the fertile crescent which is an excellent area for farming. This area is in Mesopotamia which is in between the Tigris and Euphrates rivers.

I. became farmers

4000 BCE

This is estimated to be the time when people started farming in the Indus valley. Most civiliztions started farming before actually becoming civilizations, this one is different as it developed agriculture as it turned into an ancient nation. By "farmers" I mean that they developed an advanced form of agriculture including the farming of crops and domestication of animals.

Money in the I.

4000 BCE

This is when the Indus valley people integrated a monetary system. All they had was trade between themselves and other countries. It is said that they had silver stamps which may have been used as a currency.

Currency in the Y.R. civilization

3900 BCE

It is said in my source that they used cowrie shells as a monetary system. It did not state what year this started. I assumed that once they had their kingdom set up they would soon start their currency. I am not sure though. I make this assumption because even though the yellow river civilization was far behind, they soon adapted some form of currency as some places had at the time

Writing starts in S.

3500 BCE

This is the time when cuniform started in ancient Sumer. Cuniform is an interesting language because it started off as pictures, and eventually turned into a complex series of lines and arrows. This is one of the most drastically changing languages, at least in form.

E. is founded

3100 BCE

This is estimated to be the time when ancient Egypt was founded. Before Egypt was founded though there were 2 sepertate kingdoms in the nile. The upper part was where the very fertile delta is and the lower part is where the more desert like region is.

E. starts trade within it's boarders

3100 BCE

This is when Egypt was trading. before it was unified by pharos it was 2 seperate kingdoms. So it is reasonable to assume that trade began then as I could not find a definate date.

S. starts trade

3000 BCE

The first known long distance trade was completed at this time. The trade was between the Mesopotamians and the indus valley people. It is thought that the traders were carrying valuable resources as why else would they go so far.

Wrting in I. started

2600 BCE

This is estimated to be the year that writing developed in the Indus valley region. Thier language seems to be ideographic. It seems they had a mix of pcture and symbols in their language.

S. has the first monetary system

2500 BCE

According to my source the rich first started accumulating currency around this time. They probably started their currency because it is easier to keep track of coins instead of goods. It was also approved by the government because it was easier to tax on.

Writing started in E.

2000 BCE

This is the year when hieroglyphics was estimated to start. Hieroglyphics are an interesting language too as they seen to be more ideographic rather than phonographic. Hieroglyphics were a writing used for religious purposes, like decorating a pharaohs grave.

Writing in ancient Y.R.

1122 BCE

This is the time when writing began in the yellow river civilization. It is pondered upon why they didn't start their language earlier. I theorise that at the time it was a small civilization and that they had no reason to have it before this point.

Farming started in ancient Y.R.

1100 BCE

This is the time when farming started on the yellow river. It was very hard to find good farmland in this area, only ten percent is usable. This meant that it took longer for the civilization to reach this point. Even though once they found the spot where all the minerals wash up from the river it waas a perfect spot for farming.

Monetary system in E. starts

500 BCE

At 500 BCE Egyptians made their money system. before that though there was bartering. I assume that they put currency into place because it is a lot easier to tax a coin than to tax a grain.

Trade started in ancient Y.R.

206 BCE

This is the time China started the silk road, the date is approximate to when the yellow river started trade. So in order to find a rough estimate I looked up when the silk road had started, which was used almost exclusively for trade. https://sites.google.com/site/1ancientcivilizationsforkids/ancient-china
