Barid (Bárith, Bar∂r) (d. 881), Norse king of Dublin, was (although his origin is uncertain) possibly a son of Ímar (qv) (d. 873), and was certainly among the allies of Amlaíb Find (Olaf the White). According to the Irish annals, Barid had a son, Uathmarán, and was perhaps also the father of one Harekr Bar∂rsson. He was in addition the foster-father of Amlaíb Find's son, Eysteinn. Barid first came to notice in 867, when with Háimir, another Scandinavian nobleman, he led an unsuccessful attack against Limerick. In 872 Barid, in alliance with his foster-son Eysteinn, brought a fleet up the Shannon and plundered the islands of Loch Rí and the surrounding countryside including Mag Luirg. On this occasion, it would appear that he captured the abbot of Terryglass (Frag. Ann., §§350, 408). The following year he led a seaborne attack on the coast of the Ciarraige, but was beaten off.
Barid took over the kingship of Dublin probably in the mid 870s, some time after the departure of Amlaíb Find. He was supported by the king of Tara, Áed Findliath (qv), against the Scandinavians of Northumbria. In 877 he defeated these intruders in battle at Strangford Lough and slew their king Albann (qv), after the latter had killed Eysteinn. He perished (881) shortly after sacking the ecclesiastical centre of Duleek and taking many captives from the sanctuary of St Cianán (qv). The Annals of Ulster attribute his death to a miracle wrought by the saint; a ritual killing is, however, suggested by claims that he was slain and burned by the people of Dublin. His grandson Sigfrid son of Uathmarán, who married a granddaughter of Áed Findliath, is reported to have raided the north coast in the early 920s. He defeated the king of Ailech, Muirchertach na Cochall Craicinn (qv) in 933. Harekr, if he was in fact a son of Barid, fell at the battle of Brunanburh (937) fighting on the side of Amlaíb (qv) (Óláfr) (d. 941) son of Gofraid.
