The 4th millennium BC spanned the years 4000 BC to 3001 BC. It marked a critical turning point in human history, characterized by the transition from late Neolithic agricultural societies into urban, state-level civilizations.
This millennium witnessed the invention of writing, the initial spread of bronze metallurgy, the adoption of the wheeled vehicle, and the rise of the first primary states in Mesopotamia and Ancient Egypt, effectively initiating recorded history.
The city states of Sumer and the (Predynastic) Kingdom of Egypt were established and grew to prominence. Agriculture spread widely across Eurasia.
World population growth relaxed after the burst that came about from the Neolithic Revolution. World population was largely stable in this time at roughly 50 million, growing at an average of 0.027% per year.[1]
