Era 4

World History Project - Origins (beta),

Societies generally grow and expand. What can we learn when they collapse? How do we restructure after a plague or a political failure? Era 4 also shines light on the so-called “Dark Age”—which may need a new name.

This course contains 4 segments:

4.0: Era 4 Overview: Collapse and Restructuring

4.1: Systems Collapse

4.2: Systems Restructure

4.3: A Dark Age?
