01. Data about the language
Language group
Indo-European / Celtic
Area
Irish is spoken by a number of families and communities scattered throughout the six counties of Northern Ireland.
The arrival of Celtic population in Ireland goes back to the III or IVth century BC. At the time of christianisation (Vth AC) Irish was spoken by most people.
The anglo-normand invasions of the XII and XIIIth century brought English as a language in Ireland. Irish culture and the language liveliness persisted in spite of official prohibitions (the law of 1537 was the strongest prohibition of the language). Irish literature goes back to the VIIth century and is therefore one of the eldest written language in Europe.
