Duinseach ingen Duach, Queen of Tara, fl. 500.

Background[edit]

Duinseach was a daughter of Dauí Tenga Uma, King of the Connachta. She was married to King Muirchertach mac Muiredaig (died 532), King of Tara. They were ancestors of the Cenél nEógain.

Battle of Seaghais[edit]

Duinseach is said to have been responsible for the battle of Seaghais in 500, where her husband killed her father.

Annalistic account of Seaghais[edit]

An account of the battle is given sub anno 499 (sic 500) in the Annals of the Four Masters:

The battle of Seaghais was fought by Muircheartach mac Earca against Duach Teangumha, King of Connaught. The cause of the battle was this, viz.: Muircheartach was a guarantee between the King and Eochaidh Tirmcharna, his brother, and Eochaidh was taken prisoner against the protection of Muircheartach. In proof of which Ceannfaeladh said:

  • The battle of Seaghais;
  • a certain woman caused it;
  • red blood was over lances,
  • By Duiseach, daughter of Duach.
  • The battle of Dealga, the battle of Mucramha,
  • and the battle of Tuaim Drubha,
  • With the battle of Seaghais,
  • wherein fell Duach Teangumha.

Against the Connaughtmen these battles were gained.
