I want to know the answer to the following question:
Even during the 3rd dynasty, what was happening to the racial makeup of the region?
All the background I'm provided with is that "The last of these eventually came to dominate the south of Mesopotamia as the Babylonian Empire, just as the Old Assyrian Empire had already done so in the north from the late 21st century BC.". Is that enough to answer the question?
Answer: no
