Celtic bardic poetry was preserved in several related languages and institutional settings, especially in medieval Ireland and Wales. Professional poets served courts and noble households by celebrating lineage, recording political memory, mourning the dead, and defending or attacking reputations through satire. Dense alliteration, intricate meters, kennings, mythic references, and formal training characterize much of the surviving work. The tradition demonstrates how poetry could function as both artistic expression and a recognized source of social power.

The Celtic Bardic Tradition was maintained by trained poets attached to courts, noble families, religious institutions, or learned communities. Bardic poetry could praise rulers, preserve genealogies, commemorate events, lament the dead, and attack wrongdoing through satire. Its authority depended on specialized education, memorized conventions, and command of inherited language and history. Related concepts include oral tradition, praise poetry, panegyric, lament, genealogy, and the poet’s social role as a keeper of communal memory.
