Sumer
Sumer () is the earliest known civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and one of the first civilizations in the world along with Ancient Egypt and the Indus Valley. Living along the valleys of the Tigris and Euphrates, Sumerian farmers were able to grow an abundance of grain and other crops, the surplus of which enabled them to settle in one place. Prehistoric proto-writing dates back before 3000 BC. The earliest texts, from c. 3300 BC, come from the cities of Uruk and Jemdet Nasr; early cuneiform script emerged around 3000 BC.

In the Old World, true writing systems developed from neolithic writing in the Early Bronze Age (4th millennium BC). The Sumerian archaic (pre-cuneiform) writing and the Egyptian hieroglyphs are generally considered the earliest true writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400–3100 BC, with earliest coherent texts from about 2600 BC.
