Compare and contrast the impact of disease and war on population within these time periods: 1. 164 ce 2. circa 1347 ce 3. 1492 ce

1--164 ce had a small pox epidemic which contributed to the decline of the Roman Empire

2--1347 ce was the height of the Black Plague contributing to population declines in Europe

3--1492 ce was the onset of small pox and other diseases entering the America decimating the population of the native populations.

The similarity between all three time periods is a period of disease which led to great numbers of population decline.
