so according to some perople and articles cyrus the great was a benovelent ruler and some say was the 1st humanitarian and that he abolished slavery and such. but i find it a bit hard to belive that an empire as big as the one cyrus had made could run without slaves.
Some people probably had a better time under the administration of the Persians than Assyria or Babylon. Most famously the Jews who had a few decades earlier had their home of Jerusalem sacked and were exiled from it by the Babylonians. In the Bible they write about Cyrus releasing them from their exile and rebuilding the temple in Jerusalem (although the latter may not have happened until Darius). But the particular idea of Cyrus abolishing slavery and not demanding fealty from other nations is a commonly repeated falsehood. The Persians practiced statecraft in a way that might be a bit more palatable to our modern senses but they were still an imperialistic superpower.
u/Trevor_Culley talks about the history of that misconception and where it originated from here (and I'm in there somewhere talking about the cyrus cylinder in general!)
