Mesopotamian civilizations formed on the banks of the Tigris and Euphrates rivers in what is today Iraq and Kuwait.
Early civilizations began to form around the time of the Neolithic Revolution—12000 BCE.
Some of the major Mesopotamian civilizations include the Sumerian, Assyrian, Akkadian, and Babylonian civilizations.
Evidence shows extensive use of technology, literature, legal codes, philosophy, religion, and architecture in these societies.
