@LeviKornelsen I think so? I remember reading something about the effects of the introduction of horses in India and how this affected all of the sub-continent. I think it was Romila Thapar's History of early India.
@LeviKornelsen not sure about Africa and India but in Precolonial Americas, definitely. Also east Asia with the breaking apart and reforming of Chinese dynasties. I think the main thing people forget is that the eras don’t line up with European eras, but the way to delineate eras still are applicable.
