EMPIRES- BIGGER TODAY THAN IN HISTORY
I've been reading Conn Iggulden's well researched historical fiction novels about the Mongol empire.
One number surprised me. Despite its vast geographical coverage the total population in the 13th Century was smaller than many countries these days. I therefor looked into other empires. Some included India and China and large parts of Africa, Current populations of the first two are each more than a billion.
Macedonian Empire 320BC 40m
Roman Empire 2nd Century CE 49m
Mongol Empire 1270 100m
Chinese Empire 1851 432m
French Empire 1939 110m
British Empire 1920 412m
This prompted various thoughts.
1. The world's population has expanded beyond sustainable levels and hugely.
2. The US empire, including client states, is bigger than any of the previous empires.
