What happened
In the Uruk Period, roughly 4000 to 3100 BCE, cities began to develop across Mesopotamia for the first time, and World History Encyclopedia identifies Uruk, in the southern region of Sumer, in what is now Warka, Iraq, as the most important and influential of them, the largest urban center and the hub of regional trade and administration between about 4100 and 3000 BCE. Uruk is credited with a run of firsts: the origin of the ziggurat, the invention of the cylinder seal used to mark property and sign documents, and, most consequentially, the further development of cuneiform writing by about 3200 BCE. Writing began as pictographs, simple pictures representing objects, pressed with a stylus into wet clay to record temple accounts, such as deliveries of sheep, before evolving into phonograms, symbols that could represent sounds and eventually record language itself, including the city's own later literary tradition centered on its king Gilgamesh.
Why it matters
This is the end point of the whole chain this timeline follows: wild grass became a dependable crop, crops fed permanent villages, villages grew into a dense town at Catalhoyuk, and finally a true city at Uruk needed a way to track its own trade, taxes, and property, and invented writing to do it. Recorded history, in the ordinary sense of names, dates, and documents, begins here.
How we know
World History Encyclopedia's dedicated article on Uruk gives the Uruk Period dates, the city's role as the largest urban center and administrative hub, and its credited innovations including the ziggurat, cylinder seal, and cuneiform. A second World History Encyclopedia article specifically on cuneiform corroborates that Uruk developed and advanced the script by about 3200 BCE, describes the wedge-shaped stylus marks pressed into clay, and gives a concrete early example of a temple accounting record.
