How did Alexander the Great affect future leaders?

Answer 1

Just as before Alexander, everyone of self-importance wanted to be as famous as Achilles, so after Alexander's overwhelming success they wanted to emulate Alexander. Ambitious Julius Caesar, governing a remote province in Spain, bemoaned the fact that at the same age Alexander ruled half the world.

Caesar set out to be greater than Alexander, and having dominated Europe, was on the eve of departing for the east, to capture Alexander's previous Asian territories and so outdo him, when he was assassinated,

Thereafter Caesar became the benchmark, with Alexander relegated to being just successful in the scale of things. Caesar's successors in the Roman Empire all called themselves Caesar. The modern German kings called themselves Kaiser (Caesar) and the Russian kings called themselves Czar (Caesar). Napoleon adopted Roman attributes.

Alexander started it in the European world, Julius Caesar took it onwards.
