Once again on my explorations of Youtube I came across a video produced by the Alternate History Hub (and I must admit that they produce some really interesting videos that inspire me to explore much deeper) speculating what would have happened if Persia had managed to invade Greece. The problem that I find with a lot of their productions is that their conclusions tend to be ‘this was so long ago it is impossible to know what would have happened’. Well, there is a whole field of counter-factual history where historians explore the ‘what might have been’ with regards to these particular historical events.
