About the O'Brien Clan Tartan
The O'Brien name — in Gaelic Ó Briain, "descendant of Brian" — is among the greatest of the royal names of Ireland, not a Scottish clan but a Gaelic royal house of Munster. Those of the name wear an O'Brien family tartan or an Irish national or county tartan, honouring their roots in the old kingdom of Thomond.
The O'Briens descend from Brian Boru, High King of Ireland, who broke the power of the Vikings at Clontarf in 1014. This collection brings a fitting Irish tartan into wearable apparel, everyday accessories, home decor and meaningful heritage gifts.
O'Brien Tartan Pattern and Colours
This collection draws on a bold ground of red and green crossed with black and lifted by fine lines — warm, regal colours fitting for a royal house of Munster and the green country of Clare along the Shannon.
O'Brien Heritage
Brian Boru rose from the kings of the Dál gCais of Thomond to become High King of Ireland, and at Clontarf in 1014 his forces broke the Norse power in Ireland — though Brian himself and three of his sons fell in the fighting. His descendants took the name Ó Briain in his honour, and ruled Thomond, the north of Munster, as kings and princes for centuries after.
From their strongholds along the Shannon the O'Briens spread through Clare, Limerick and north Tipperary, and gathered many titles: Barons and Earls of Inchiquin, Viscounts Clare, and Earls and Marquesses of Thomond. Their great houses include Bunratty Castle, Leamaneh and Dromoland. The head of the family is still styled The O'Brien, Prince of Thomond and Baron Inchiquin — one of the few Gaelic royal lines whose chief is recognised to this day.
