Alexander the Great is a good bet, Attila the Hun too, however as "great" as their achievements, I think that in terms of the person who has influenced the most people and had the greatest influence overall, I would say that it is probably Bill Gates.
I think probably Alexander the Great or somebody like .
Tler might not be a nice guy, but he has influenced a lot of people to do the opposite of what he did!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
