Tuatha Dé Danann
The Tuatha Dé Danann (usually translated as "people(s)/tribe(s) of the goddess Danu"), also known by the earlier name Tuath Dé ("tribe of the gods"), are a race of supernaturally-gifted people in Irish mythology. They are thought to represent the maindeities of pre-Christian Gaelic Ireland.
Much of Irish mythology was recorded by Christian monks, who modified it to an extent. They generally depicted the Tuath Dé as kings, queens and heroes of the distant past who had supernatural powers or who were later credited with them. However, some writers acknowledged that they were once worshipped as gods. A poem in the Book of Leinster lists many of them, but ends "Although [the author] enumerates them, he does not worship them". Danann is generally believed to be the genitive of a female name, for which the nominative case is not attested. It has been reconstructed as Danu, of which Anu(genitive Anann) may be an alternative form. Anu is called "mother of the Irish gods" by Cormac mac Cuilennáin. The Tuatha Dé Danann then fought the Second Battle of Magh Tuireadh against the Fomorians. Nuada was killed by the Fomorian king Balor's poisonous eye, but Balor was killed himself by Lugh, the champion of the Tuatha Dé, who then took over as king. A third battle was fought against a subsequent wave of invaders, the Milesians, from the northwest of the Iberian Peninsula (present day Galicia and Northern Portugal), descendants of Míl Espáine (who are thought to represent the Goidelic Celts). The Milesians encountered three goddesses of the Tuatha Dé Danann, Ériu, Banba andFodla, who asked that the island be named after them; Ériu is the origin of the modern name Éire, and Banba and Fodla are still sometimes used as poetic names for Ireland.
