Niall of the Nine Hostages

Niall Noígíallach (pronounced; Old Irish "having nine hostages"), or Niall of the Nine Hostages, was a legendary, and possibly historical, Irish king. He was reputedly a High King of Ireland, and the progenitor of the Uí Néill dynasties who dominated Ireland from the 6th to the 10th centuries. Although Irish annalistic and chronicle sources place his reign in the late 4th and early 5th centuries, modern scholars date him about half a century later.
