5th century in Ireland

Events from the 5th century in Ireland.

5th century

405

• Possible year of death of Niall Noígíallach. The Annals of the Four Masters dates his accession to 378 and death to 405.^[1] The chronology of Geoffrey Keating's Foras Feasa ar Éirinn broadly agrees, dating his reign from 368 to 395, and associating his raiding activities in Great Britain with the kidnapping of Saint Patrick.^[2] However, the traditional roll of kings and its chronology is now recognised as artificial. The High Kingship did not become a reality until the 9th century, and Niall's legendary status has been inflated in line with the political importance of the dynasty he founded. Based on Uí Néill genealogies and the dates given for his supposed sons and grandsons, modern historians believe that he is likely to have lived some 50 years later than the traditional dates, dying circa 450.^[3]

410

• At about this date, with the end of Roman rule in Britain, raiders from Ireland such as the Uí Liatháin and Laigin harry the coasts of Britain.
