Red Branch

The Red Branch (from Old Irish Cróeb Ruad, meaning "dull red branch"; alternatively, from Old Irish Cróeb Derg, meaning "bright red branch") is the name of two of the three royal houses of the king of Ulster, Conchobar mac Nessa, at his capital Emain Macha (Navan Fort, near Armagh), in the Ulster Cycle of Irish mythology. In modern retellings it is sometimes used as the name of an order of warriors, the Red Branch Knights.

The names of two of Conchobar's houses can be translated as "Red Branch", as Old Irish had two words for "red": derg, bright red, the colour of fresh blood, flame or gold; and ruad, russet, used for the colour of dried blood and for red hair. The Cróeb Ruad (modern Irish Craobh Rua, "russet branch") was where the king sat; its name has survived as the townland of Creeveroe in County Armagh. The Cróeb Derg (modern Irish Craobh Dearg, "bright red branch") was where severed heads and other trophies of battle were kept. His third house was called the Téite Brec or "speckled hoard", where the heroes' weapons were stored.
