So far from different perspectives discussed in this forum by members, the view on Alexander the Great was not universal.
Anyhow, he was the undefeated warrior king who never lost a battle , and his legacy continues to be as strong as the days of Hellenism.
I tend not to compare the different empires and various historical personalities as I have much respect of all.
Hypothetically speaking, would it change the entire course of history if Alexander did not die young in 323 B.C. but lived on to conquer either Rome and celtic tribal nations in Europe or Scythians or Carthage and Arabia. 3 most striking possibilities would be :
Even if it would be very doubtful whether the Macedonian phalanx would be enough to overcome Nanda empire which could have fielded thousands of war elephants corps, it would have stopped the ascendency of mauryan house if Alexander's grip its indian vassals were strong and , also supportive.
If the armies of Alexander ventured further beyond Sogdia, there would be nothing stopping him from reaching China proper except some oasis city states . Then the first state of warring China would be Qin . The contact between unknown-to-each-other civilizations would be ???
Or Rome was conquered in his time before its rise , it would have change the whole course of European history.
But they are all ifs and buts ,
