1100s Irish History

The following were the names of the principal families in Ireland, of Irish, Anglo-Norman, and Anglo-Irish origin. This list from "Irish Pedigrees" by John O'Hart, vol. 2.

This exhibition looks at how the governments and people of England, Scotland, Ireland and Wales, and of England's French territories, interacted in politics, warfare, religion, trade and everyday life.

From 1086 to 1114 the most powerful king in Ireland was Muirchertach O'Brien. He had dealings with the Anglo-Normans and the Norwegian king, and dominated most of the country.

Ireland in the 10th century had been dominated by the power of the Uí Néill but, curiously, it was their own zealousness that led to the rise of their most effective opponent in the race for the High Kingship.
