“Mesopotamia” means the land between two rivers
The Greek name—recorded from the fourth century BC—labels the country between Euphrates and Tigris, today’s Iraq and neighboring fringes of Iran, Syria, and Turkey. There, after farming took hold, the Uruk period grew the first true cities and, by the late fourth millennium, cuneiform writing.
Scholars treat “Mesopotamia” as a historical label mainly up to the seventh-century Arab conquests, after which Arabic names such as Iraq predominate. Upper Mesopotamia runs from the rivers’ sources down to Baghdad; Lower Mesopotamia continues to the Gulf. Relative chronologies come from excavated strata; absolute dates use radiocarbon, tree rings, and year names. For the third and second millennia BC, Ultra-long through Ultra-short schemes still disagree by as much as 150 years, yet many handbooks keep the Middle Chronology, which a 2001 Turkish radiocarbon study roughly supports for the second millennium.
Early Neolithic sites clung to Taurus–Zagros foothills: Körtik Tepe near 10,400 BC, PPNA agriculture (10,000–8,700 BC), and early domestication into PPNB. Göbekli Tepe’s monumental stone circles belong to PPNA/early PPNB hunter-gatherer communities. Southern alluvium required irrigation; Eridu rose in the Ubaid period (about 6500–3800 BC in the south; northern Ubaid about 5300–4300 BC) as Samarran farmers moved south. Halaf, Hassuna, and Samarra cultures painted fine pottery and figurines across the north before Ubaid styles spread—most likely by adoption rather than invasion, since no occupational hiatus appears.
The Uruk period named for the Sumerian city saw urban life emerge; late Uruk (34th–32nd centuries BC) gradually produced cuneiform in a “Protoliterate” Early Bronze Age. Jemdet Nasr (about 3100–2900 BC) refined administrative tablets—likely in Sumerian—listing rations and cities including Ur, Uruk, and Larsa. Early Dynastic Sumer (Middle Chronology about 2900–2350 BC) stacked irrigation surpluses, temple building, and rival city-states such as Kish, Uruk, Ur, and Lagash. Gilgamesh of Uruk belongs to this horizon; by about 2600 BC logographic signs had become a readable cuneiform syllabary. Sumerian itself is a language isolate, leaving origins debated.
