4th millennium BC

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.

Sub-Saharan Africa

Sub-Saharan Africa remains in the Paleolithic period, except for the earliest neolithization of the Sahel following the desiccation of the Sahara in c. 3500 BC. As the grasslands of the Sahara began drying after 3900 BC, herders spread into the Nile Valley and into eastern Africa (Eburan 5, Elmenteitan). The desiccation of the Sahara and the associated neolithisation of West Africa is also cited as a possible cause for the dispersal of the Niger-Congo linguistic phylum.
