General Notes
- "Niall held sway over the largest amount of territory ever controlled by an Irish king until that point, and his kingdom was only eclipsed by his nephew and successor, Dalphi. He controlled all of Ireland, large portions of Britain, and even part of France. He seriously damaged Roman ability to control Britain and Gaul and helped bring about the end of the Empire in the north."
