The National Eisteddfod of Wales is the largest of several eisteddfodau that are held annually, mostly in Wales. Its eight days of competitions and performances are considered the largest music and poetry festival in Europe. Competitors typically number 6,000 or more, and overall attendance generally exceeds 100,000 visitors, the highest recently being 118,000 attending the 2022 festival. The 2018 Eisteddfod was held in Cardiff Bay with a fence-free 'Maes'. In 2020, the event was held virtually under the name AmGen; events were held over a one-week period.

Welsh is a Celtic language of the Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales, by some in England, and in Y Wladfa.
