King Brian Boru The Last High King of Ireland
The small passage tomb known as the Mound of the hostages or Duma na NGiall dates to around 2500BC. The tomb gets its name from the custom of Irish kings taking important people hostage, one of these kings was known as Niall of the Nine Hostages who had taken hostages from all of the provinces of Ireland and from other countries. The passage tomb is one of only two monuments at Tara that have been excavated.
According to later writings, Diarmait was the son of Fergus Cerrbél, son of Conall Cremthainne, son of Niall of the Nine Hostages. As a great-grandson of Niall, he and his descendants were counted among the Uí Néill. The Uí Néill as such, the name means "grandsons of Niall", can only have existed in the time of Niall's grandsons, but its common usage may be later yet as an earlier term moccu Chuinn is attested as late as the time of Saint Columba (died c. 597), a great-grandson of Niall's.

Cormac mac Airt (son of Art), was, according to medieval Irish legend and historical tradition, a High King of Ireland. He is probably the most famous of the ancient High Kings, and may have been an authentic historical figure, and his reign is variously dated as early as the 2nd century and as late as the 4th. He is said to have ruled from Tara, the seat of the High Kings of Ireland, for forty years, and under his rule Tara flourished. He was famous for his wise, true, and generous judgments.
