By the way, there were Greeks in Anatolia called Ionian Greeks who will become relevant shortly. So even if you weren't Persian, the Persian Empire was pretty dreamy. For one thing, the Persians ruled with a light touch, like conquered kingdoms were allowed to keep their kings and their elites as long as they pledged allegiance to the Persian king and paid taxes, which is why the Persian king was known as the King of Kings. Plus taxes weren't too high and the Persians improved infrastructure with better roads and they had this pony express-like mail service of which Herodotus said, They are stayed neither by snow nor rain nor heat nor darkness from accomplishing their appointed course with all speed. And the Persians embraced freedom of religion, like they were Zoroastrian, which has a claim to be the world's first monotheistic religion. It was really Zoroastrianism that introduced us to the good-evil dualism we all know so well, you know, God and Satan or Perry and Voldemort. But the Persians weren't very concerned about converting people of the empire to their faith.
