jul 1, 1125 BC - Egypt loses direct control of Canaan

Description:

"Opponents of the Egyptian authority were of local extraction, probably originating in Canaanite cities of the Levantine coastal plain,[95] an opposition to Egyptian hegemony ultimately resulting from the arrival of the Sea People in the region during the reign of Ramesses III"

Radiocarbon dating suggested the Joppa was destroyed twice around 1125 BC; with this date being the subsequent post quem for Egypts end of rule in Canaan

Is this when the Philistines began their oppression?
