The Uí Néill (Irish pronunciation: [iː ˈnʲeːl̪ʲ], descendants of Niall) are Irish and Scottish dynasties who claim descent from Niall Noigiallach (Niall of the Nine Hostages), a historical King of Tara who died about 405.
The first generation of the Uí Néill were his sons, seven in all:
All these men were in their lifetime known as members of The Connachta dynasty, or as "the sons of Niall." The term Uí Néill did not - by its very nature - come into use until the time of Niall's grandsons and great-grandsons.
Dynasties descended from the Uí Néill, such as the Cenél Conaill and Cenél nEógain, held power in Ulster until their defeat in the Nine Years War in 1603. Many of the heads of the families left for Catholic Europe in 1607, an event known as the Flight of the Earls.
