This really belongs in the Ancient History forum. But here's what I would say
I think a good general point to make about Alexander, one that would serve as an invitation to discuss all those points and more, was that he was creating an inclusive Empire, respecting local culture rather than putting his own forward dominantly (but he did also promote Hellenisation) he seemed to have typical un-Greek views on foreigners, he viewed that they should be integrated into a larger Empire alongside Europeans, rather than tyranically controlled.
You could say that to them he went from brutal conqueror to a populist despot.
- He gave the Lydians their old constitution back.
- He followed traditional customs of Asia Minor, like solving the mystery of the Gordium knot
- He cultivated an image as the liberator of Egypt and proclaimed himself Zeus-Ammon (although that was also probably part of his ego
- He made himself appear to the Persians as the new Great King by giving Darius a royal funeral, adopting their dress and including them into the army. This galvanised his popular support as the new King.
- He was rather courteous to most Indians he met, gave them autonomy in their region (perhaps due to a sense of his own acute weakness)
- Continued practice of satrapy.
- Barbarians like the Illyrians, Scythians and parts of Thrace he help simply crushed into submission.
All this however, came at the price of alienating him from his Greeks and Macedonians, but that is really another topic.
