Why did the ancient greeks abolish slavery? and i have my own reasons i want to go deeper into detail.

I would say for more work to be done, and make things a lot easier to be done by that fact.

The ancient greeks abolished slavery because they thought it was morally wrong in the eyes of Hera aulthough cold she is the godess of childbirth fertility and mother hood
Now this is my personal opinion but since im greek i believe that is why slavery was infact abolished
It was the most reasonable if answers

The answer is ethnic groups.
