Máel Sechnaill mac Domnaill
Máel Sechnaill mac Domnaill, also called Máel Sechnaill Mór or Máel Sechnaill II, was a King of Mide and High King of Ireland. His great victory at the Battle of Tara against Olaf Cuaran in 980 resulted in Gaelic Irish control of the Kingdom of Dublin.

High King of Ireland was a royal title in Gaelic Ireland held by those who had, or who are claimed to have had, lordship over all of Ireland. The title was held by historical kings and was later sometimes assigned anachronously or to legendary figures.

High kings were traditionally installed on the Hill of Tara. The Lia Fáil (pictured) shouted the rightful king's name when he placed his foot on it, according to tradition.
