What was the main similarities and differences between sumerian and babylonian civilizations?

Both Sumerian and Babylonian civilizations were located in Mesopotamia and contributed significantly to early human history through advancements in writing, law, and urban development. A key similarity is their use of cuneiform writing and the establishment of city-states. However, a major difference lies in their political structure; while Sumer was characterized by multiple independent city-states, Babylon emerged as a centralized empire under prominent rulers like Hammurabi, who is known for his codification of laws. Additionally, the Babylonians built upon Sumerian achievements, integrating and expanding their religious and cultural practices.
