Decline and End

During the eighth and seventh centuries BC, the Philistine cities increasingly came under Assyrian control. Their rulers often retained local authority but were required to pay tribute and support imperial policies.

Rebellions against Assyria sometimes resulted in military campaigns, destruction, or the replacement of local rulers.

Babylonian expansion at the end of the seventh century BC brought devastating destruction to several Philistine centers. Ekron and Ashkelon were among the cities severely affected.

The traditional political system of independent Philistine city-states did not survive these changes.

The cities themselves continued to exist or were later resettled, and the coastal region became part of the Persian, Hellenistic, and Roman worlds.

Over time, the distinctive Philistine cultural identity of the early Iron Age faded into the broader population and culture of the region.
