The first annalistic mention of a ""High King of Ireland"" or ""Ard-Rí"" was Máel Sechnaill mac Máele Ruanaid, King of Mide, who died in 862 AD, having achieved many victories against both the Norse and the kingdoms of Ulster. Later historians would retroactively apply the title of "High King" to the earlier Kings of Tara, although there were no contemporary references to either the Kings of Tara or Mide being referred to as "Ard-Rí" prior to the 9th century. During the reign of Máel Sechnaill mac Domnaill in the 970s, the fort of Dun-na-Scia near Lough Ennell became the permanent royal residence, thereby creating two seats of power within the kingdom - one for the High King and one for the King of Mide.
