Baile Átha Cliath · Leinster
The oldest trace of people in Dublin is five wooden fish traps found near Spencer Dock in 2007, made with stone axes between about 6100 and 5700 BC. The Vikings founded the town in the 9th century, and under them it became the largest slave market in western Europe. Irish kings pushed back: the Norse were exiled as early as 902, Máel Sechnaill II took the town in 980 and freed its Irish slaves, and after Brian Boru's victories, Clontarf in 1014 above all, Dublin was a lesser kingdom.
