The Irish once tried to colonize Britain.
For example, in the 5th century CE, there was a battle between Welsh King Cadwallon I and Irish King Serigi Wyddel—which drove the Irish king out of Anglesey.
Irish invasions may have been a factor in why the Romano-Celts hired the Germanic tribes as mercenaries.
