After 50 years of warfare trying to enforce peace amongst the Greek city-states, the Persians agreed in 449 BCE to peace and left the Greek cities to go back to destroying each other, and turned their full attention to maintaining peace and prosperity within their empire. They intervened 60 years later, imposing the 'King's Peace' to stop these disruptions spilling over into their empire.
