What is recorded here

Cúl Dreimhne is a major battlefield in County Sligo, Ireland, where the Uí Néill defeated the Laighin in 561 CE. Traditional accounts describe the conflict as the Battle of the Book, triggered when Columcille copied a manuscript belonging to Saint Finnian and the High King ruled that the copy belonged to Finnian. The Uí Néill victory expanded their dynasty, while the alternate sanctuary story ties the fight to Diarmuid Mac Cearbhail killing Curnan mac Aed under Columcille’s protection.

The battle of Cúl Dreimhne (also known as the Battle of the Book) took place in the 6th century in the túath of Cairbre Drom Cliabh (now County Sligo) in northwest Ireland. The exact date for the battle varies from 555 AD to 561 AD. 560 AD is regarded as the most likely by modern scholars.

The Battle of Cúl Dreimhne was fought in the 6th century between the forces of the Northern Uí Néill and the Connachta in what is now County Sligo. The battle is notable for the death of the High King Diarmait mac Cerbaill, marking a significant shift in political power in early medieval Ireland.
