What consequence did the Persian suffer after the battle of marathon

The Persian punitive expedition against Athens went home. Persia then decided to bring all the Greek city-states in mainland Greece within its empire to stop them supporting rebellions in Asia Minor. It mounted a full scale invasion ten years later, which was repelled by a combination of the southern Greek cities. This too was repelled, and then after thirty years of further warfare Persia gave up and a peace was agreed.
