Categories: main-event

Rising post-glacial seas flooded the lowlands known as Doggerland and separated Britain from continental Europe. Within the broader Prehistoric Britain period, communities moved from hunter-gatherer lifeways toward farming, monument building, metalworking and increasingly complex regional societies. This event is placed at c. 6000 BCE in the chronology so it can be read alongside the political, military, social and cultural changes around it. The permanent sea barrier shaped later migration, trade and defence while never ending Britain's links with the continent.
