History

Earliest governments

The moment and place that the phenomenon of human government developed is lost in time; however, history does record the formations of early governments. About 5,000 years ago, the first small city-states appeared. By the third to second millenniums BC, some of these had developed into larger governed areas:

The human ability to precisely communicate abstract, learned information allowed humans to become ever more effective at agriculture, and that allowed for ever increasing population densities. David Christian explains how this resulted in states with laws and governments.
