The 3rd millennium BC spans the Early to Middle Bronze Age.

This was a period of time in which the desire to conquer was common. Expansion occurred throughout the Middle East and throughout Eurasia, with Indo-European expansion to Anatolia, Europe and Central Asia. The civilization of Ancient Egypt rose to a peak with the Old Kingdom. World population is estimated to have doubled in the course of the millennium to 30 million people.
