Sumer
Sumer (/ˈsuːmər/) was the first ancient urban civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and arguably the first civilization in the world.
Proto-writing in the region dates back to c. 3500 BC. The earliest texts come from the cities of Uruk and Jemdet Nasr and date back to 3,300BC; early cuneiform writing emerged in 3,000 BC.
