The Vikings in Ireland: Founding of Dublin
On the timeline · around 841 CE ·
What happened
After decades of raiding Ireland's monasteries, Norse invaders established a fortified ship-camp at Dublin in 841. It grew into a thriving town and one of the greatest slave markets of the early medieval world.
Why it matters
Dublin was one of the first Viking towns and a hub of their vast trading network — a reminder that the Norse were city-founders and merchants as much as raiders.
