Gaelic Nobility of Ireland - The Gaelic Nobles

The Gaelic Nobles

All below are flatha (princes) and also descendants in the male line, however distant in some cases, of at least one historical grade of Rí, a Rí túaithe (usually a local petty king), a Ruiri (overking or regional king), or a greater Rí ruirech (king of overkings, also called a provincial king or Rí cóicid). A number of rí ruirech also became Ard Rí and their surviving princely descendants remain claimants to the long vacant, so-called High Kingship. A modern Gaelic noble may be styled a flaith (prince) or tiarna (lord, count/earl). See also White Rod.

The Gaelic families are divided by race and sept, and by geography.
