Glún Iairn’s Fatal Cup
Archived: 26 October 2026
Abstract
The annals for 989 preserve a year of abrupt reversals. Ireland was not a single kingdom, nor was its political life divided neatly between ‘Irish’ and ‘Viking’. Kingship was exercised through shifting local alliances, hostage-taking, tribute, raiding and control of major churches. The most striking entry is the death of Glún Iairn, king of the foreigners of Dublin, killed while drunk by his own slave. Yet 989 mattered just as much in the north: Dún Lethglaise, modern Downpatrick, was plundered and burned; a ruler of the Isles was killed in Dál Riata; and the successor of St Patrick at Armagh
