How did Sumer affect Babylon? How did Babylon affect Sumer?

Answer 1

Sumer affected Babylon in that Sumer was the first civilization to arise in the middle eastern area and so they influenced all latter civilizations that came after them such as the Babylonians. They laid the intellectual groundwork (astronomy, mathematics, engineering, etc...) that later groups would use and expand on. Invaders of Sumer did not destroy her but instead kept her institutions, beliefs, discoveries while adding some of their own.

Babylon didn't affect Sumer because by the time Babylon arose sumer was effectively dead as an individual civilization or rather it had morphed and evolved into the Babylonians and other groups.

Basically sumer was the wellspring from which other civilizations such as Babylon sprang.

Answer 2

Just how did Sumer affect Babylon.

Following an Elamite invasion and sack of Ur during the rule of Ibbi-Sin (ca. 2004 BC), Sumer came under Amorite rule (taken to introduce the Middle Bronze Age). The independent Amorite states of the 20th to 18th centuries are summarized as the "Dynasty of Isin" in the Sumerian king list, ending with the rise of Babylonia under Hammurabi in the ca. 1730 BC.
