If I understand correctly, one could hold that Hitler and Einstein and Genghis Khan etc. were special individuals who happened to arise and significantly bend history. Or, one could hold that the course of history is mostly shaped by deeper currents based on changes in technology, social structures, climate, and what have you, and that if (say) Lenin or Luther etc etc had not been born things would still have proceeded roughly as they did, long term. (Or of course some more nuanced synthesis of these theories.)
Is there a general consensus among historians either way, two opposing camps, or what? Or am I maybe understanding the question wrongly?
There's always more that can be said, but you may find this Monday Methods post by /u/commiespaceinvader useful.
