In Welsh culture, an eisteddfod is an institution and festival with several ranked competitions, including in poetry and music.
The term eisteddfod, which is formed from the Welsh morphemes: eistedd, meaning 'sit', and fod, meaning 'be', means, according to Hywel Teifi Edwards, "sitting-together." Edwards further defines the earliest form of the eisteddfod as a competitive meeting between bards and minstrels, in which the winner was chosen by a noble or royal patron.
The first documented instance of such a literary festival and competition took place under the patronage of Prince Rhys ap Gruffudd of the House of Dinefwr at Cardigan Castle in 1176. However, with the Edwardian Conquest of Wales, the closing of the bardic schools, and the Anglicization of the Welsh nobility, it fell into abeyance. The current format owes much to an 18th-century revival, first patronized and overseen by the London-based Gwyneddigion Society. It was later co-opted by the Gorsedd Cymru, a secret society of poets, writers, and musicians founded by Iolo Morganwg, whose beliefs were "a compound of Christianity and Druidism, Philosophy and Mysticism."
Despite the Druidic influences and the demonstrably fictitious nature of Iolo Morganwg's doctrines, rituals, and ceremonies, both the Gorsedd and the eisteddfod revival were embraced and spread widely by Anglican and nonconformist clergy. The revival therefore proved enormously successful and is credited as one of the primary reasons for the continued survival of the Welsh language, Welsh literature, and Welsh culture after more than eight centuries of colonialism.
During his two 20th-century terms as Archdruid of the Gorsedd Cymru, Albert Evans-Jones, whose bardic name was Cynan and who was a war poet and minister of the Presbyterian Church of Wales, created new rituals for both the Gorsedd and the eisteddfod which are based upon the Christian beliefs of the Welsh people rather than upon Modern Druidry.
