BTW, the actual date of economic collapse of the entire world was about 538 AD. The event occurred in the Spring. All hell broke loose after that.

This is 6th Century stuff. The Western Roman Empire had a political collapse in the 5th Century, but the economic collapse happened later!

China was also removed as a working entity for the next 300 years as well!
