Deirdre

DEER-drah

A woman prophesied at birth to bring ruin to Ulster, whose flight from King Conchobar and tragic end give the Ulster Cycle one of its most sorrowful tales.

Deirdre's story begins before she is even born: at her birth, the druid Cathbad prophesies that she will grow into great beauty, but that her beauty will bring war and ruin to Ulster and death to its finest warriors. Despite calls to have the infant killed to prevent the prophecy, King Conchobar mac Nessa instead decides to raise her in seclusion, intending to marry her himself once she comes of age, keeping her away from all other men in the meantime. As a young woman, Deirdre sees a raven drinking the blood of a calf slaughtered in the snow and tells her guardian she wants a husband with hair as black as the raven, skin as white as the snow, and cheeks as red as the blood — a description that leads her to Naoise, a young warrior of the Red Branch. The two fall in love, and despite knowing the danger of defying the king, Deirdre convinces Naoise and his brothers to flee with her, escaping Ulster and Conchobar's claim on her entirely, living for years in exile, often in Scotland. Conchobar eventually lures them back with a false promise of safety and forgiveness, guaranteed by Fergus mac Róich's own honor as surety — but has Naoise killed on arrival regardless, betraying both Deirdre and Fergus, whose fury at the broken guarantee drives him into open rebellion against Ulster (fueling the later events of the *Táin*). Deirdre herself is forced into Conchobar's household after Naoise's death, but in most versions of the tale, she never accepts him — some accounts have her die of grief within a year, others have her take her own life rather than remain in his power, fulfilling Cathbad's prophecy in full and giving the tale its common title, "The Exile of the Sons of Uisneach" or simply "Deirdre of the Sorrows."

Frequently Asked Questions

Who is Deirdre?

Deirdre (Deirdre of the Sorrows) is the tragic heroine of Longes mac nUislenn, whose birth is prophesied to bring ruin to Ulster, and who grows up to flee with her true love Naoise rather than marry King Conchobar as intended.

Why is Deirdre called "of the Sorrows"?

Her story ends in grief on every side — Naoise and his brothers are killed through Conchobar's treachery after being lured back to Ulster, and Deirdre herself dies rather than live as Conchobar's forced bride.

How is Deirdre connected to the wider Ulster Cycle?

The fallout from Conchobar's betrayal drives Fergus mac Róich and other Ulster warriors into exile in Connacht, where they later side with Medb against Ulster during the Táin Bó Cúailnge.
