Answer: 1000 years
Step-by-step explanation:
-Greek city-states began to form in 800 B.C i.e 800 years Before Christ appearance
- up till 200 A.D i.e 200 years of After Christ disappearance
Hence, the number of years between the time that Greek city-states began to form and the persecution of Christians began is equal to the sum of years Greek city States started formation and Year persecution began
