1. Rise of the Early River Valley Civilizations

2. What do these regions have in common?

3. Rivers Sumerian Civilization - Tigris & Euphrates Rivers (Mesopotamia)
Egyptian Civilization - Nile River
Harappan Civilization - Indus River
Ancient China - Huang He (Yellow) River

4. Key Definitions
a) climatic: resulting from or influenced by the climate rather than the soil
b) geographic: belonging to or characteristic of a particular region
c) environmental: the conditions that surround someone or something : the conditions and influences that affect the growth, health, progress, etc., of someone or something

6. DO NOW: Take out your homework for a check
Be prepared to talk about common environmental, power/authority, and science/technological themes among the 4 river valley civilizations

7. Mesopotamia
Mesopotamia comes from Greek words meaning "land between the rivers."

8. Mesopotamia: Geography
- The climate in southwestern region of Asia (i.e. the Middle East) is typically arid and lacking available water sources except an arable region between Tigris / Euphrates rivers known as Mesopotamia
- Mesopotamia was located between the two rivers in an area called the Fertile Crescent because of the region’s shape and the richness of its soil
- The rivers flood at least once a year and leave a thick bed of mud and silt.

10. Tigris and Euphrates The Tigris is rough and fast flowing.
The upper course in particular is difficult to pass.
The river cuts deep in the surrounding land and the water flow can hardly be used for irrigation.
The Euphrates is a lifeline.
It can more easily be used by ships.
The banks are lower, suitable for irrigation, with less violent floods.

11. Question:
Based on this information, what were some of the environmental challenges facing the Sumerians?
How did the Sumerians confront these environmental challenges?

12. Environmental Challenges
Sumerians were first to settle in this region, attracted by the rich soil.
Three Disadvantages / Environmental Challenges
Unpredictable flooding / dry summer months
No natural barriers for protection -small villages lying in open plain were defenseless
Limited natural resources - especially lacking stone, wood, metal

13. Solutions Irrigation ditches Built city walls with mud bricks
Trade with people around them for the products they lacked

14. Irrigation Systems
The earliest irrigation system emerged around 6000 BCE
Sumerians used a system of dikes, dams and canals to irrigate the land
Required a high level of organization of the society for the construction, maintenance, supervision and adjustments of the irrigation network.
Irrigation network stimulated the foundation of new settlements and cities.

15. Question
Imagine you were an Ancient Sumerian tasked with organizing the irrigation system in Mesopotamia....
Who would be in charge?
How would the necessary tasks/responsibilities be delegated?
How would you ensure that the systems in place remained reliable?

16. Initial Governmental Structure
•Early gov’t controlled by temple priests
•Priests controlled food production and irrigation systems
•Priests took portion of every farmer’s crops as taxes

17. Do Now:
Please take out the handout from yesterday, read the second source document, and answer the questions in your groups.
Please be prepared to share your responses with the rest of the class.

18. City-States in Mesopotamia City-States of Mesopotamia
The City-State Structure of Government
Although all the cities shared the same culture …
Each city had its own government comprised of rulers, warriors,
its own patron god, and functioned like an independent country
including farmland surrounding its city walls.
Examples include Sumerian cities of Ur, Uruk, Kish, Lagesh
At center of each city was the walled temple with a ziggurat – a massive, tiered, pyramid-shaped structure.

20. UR: The Ziggurat at Ur was first excavated by British archaeologist Woolley in 1923.The Iraqi Directorate of Antiquities restored its lower stages in the 1980s

21. Question
Make some predictions, why did priests gradually lose power/influence? How did kings emerge as the centers of power?

22. Rise of the Sumerian Kings
•Men chose a tough fighter to lead city in war
•Power ended at end of war
•Some military leaders became rulers and would pass power on to their son, forming a dynasty

24. Epic of Gilgamesh
Story of King Gilgamesh of Uruk- a ruthless and oppressive leader
The gods punish his prideful behavior by killing his best friend (Enkidu)
Gilgamesh undertakes a quest for immortality
Travels to the home of Utnapishtim, the only mortal saved from the Great Flood and granted immortality
Very similar to Homer’s Odyssey

25. How the epic was discovered?
Originally written in cuneiform script in Sumerian legends/poems and later gathered into a longer Akkadian poem preserved on 12- clay tablets
The so-called “standard” Akkadian version, consisting of twelve (damaged) tablets written by the Babylonian scribe Sin-liqe-unninni some time between 1300 and 1000 BCE
Discovered in 1849 in the library of the 7th Century BCE Assyrian king, Ashurbanipal, in Nineveh, the capital of the ancient Assyrian empire (in modern-day Iraq)

26. Gilgamesh https://www.youtube.com/watch?v=qOrfrHys8g8
While you view the clip, please generate a list of how you’d describe Gilgamesh as a leader.

27. The Story of the Flood
God saw how great wickedness had become and decided to wipe mankind from the face of the earth
One righteous man among all the people of that time, Noah, found favor in God's eyes
With very specific instructions, God told Noah to build an ark for him and his family in preparation for a catastrophic flood that would destroy every living thing on earth

28. Achievements •Invented wheel, sail, and plow
•Developed number system in base 60, which is used for modern time and measuring a circle
•Architecture
•System of writing called cuneiform

29. Mesopotamian Society Social classes
•Kings, landholders, and some priests were highest level
•Wealthy merchants were upper class
•Most Sumerians worked in fields or workshops and were middle class
•Slaves were lowest level
•Slaves were prisoners of war or Sumerians sold as children to pay of debts of their poor parents

30. Decline of Status of Women
Women had more rights than in many later civilizations
lower class women not allowed to attend schools (could not read or write)

31. Question:
Please work in your groups to define the term cultural diffusion.

33. Evidence of Cultural Diffusion
Definition: spread of elements of one culture to another people,
generally through trade.
Example: Consider the spread of writing. Similarities between the pictograms of Egyptian hieroglyphics, Sumerian cuneiform, and the Indus script are striking.
Please provide some examples of evidence of cultural diffusion that you observe in today’s world.
