Sitriuc mac Ímair
Sitriuc mac Ímair (Sigtryggr Ívarrsson) was a 9th‑century King of Dublin who died in 896. He was the son of Ímar and a member of the Uí Ímair dynasty. Sitriuc became king in 888 after his brother Sichfrith. His reign saw Dublin racked by internal feuds, though the city won fights against Leinster and the Southern Uí Néill. In 893 he faced a rival king, Jarl Sichfrith; both men led campaigns in Britain that year, and on Sitriuc’s return it’s unclear who kept the throne. He was killed in 896 by unnamed Vikings, a year that also saw the deaths of Glúntradna, son of Glúniarann, and Amlaíb, Ímar’s grandson, weakening Dublin. Some think Glúniarann may have become king after Sitriuc. Sitriuc had brothers Bárid and Sichfrith, who had ruled Dublin before him. Ímar is sometimes identified with Ivar the Boneless, a famous Viking leader who invaded England in 865; Norse stories also say Ímar was a son of Ragnar Lothbrok and brother to Björn Ironside and Halfdan Ragnarsson. Ímar had several grandsons—Ragnall, Ímar, Sitric Cáech, Amlaíb, and Gofraid—but it’s not clear which were Sitriuc’s children.
