The Vikings in Ireland: The Founding of Dublin
On the timeline · around 841 ·
What happened
From the 790s Norse raiders struck Ireland's rich monasteries, and by 841 they had built fortified ship-camps — longphorts — including one at Dublin. From these bases they became players in Irish trade and politics.
Why it matters
Dublin and other Norse towns grew into major centers of trade and power, and the Vikings left a lasting mark on Ireland's commerce, towns, and culture.
