when did the roman empire reach its greatest extent?
under trajan
the written, archaeological and natural-scientific proxy evidence independently but consistently shows that during the period of the roman empire's maximum expansion and final crisis, the climate underwent changes. the empire's greatest extent under trajan coincided with the roman climatic optimum. the climate change occurred at different rates, from apparent near stasis during the early empire to rapid fluctuations during the late empire. still, there is some controversy in the notion of a generally moister period in the eastern mediterranean in ad–600 ad due to conflicting publications.
