Amlaíb Cenncairech
Amlaíb Cenncairech was a Norse ruler and presumably King of Limerick notable for his military activities in Ireland in the 930s, especially in the province of Connacht and apparently even in Ulster and Leinster. This period, the 920s and 930s, is commonly regarded as the very height of Norse power in Ireland, and was when Limerick essentially equalled Dublin in power. His epithet "Cennc(h)airech" is commonly translated into the unflattering "Scabby-Head" but this may be inaccurate. The adjective "cairech" actually means, according to the "Dictionary of the Irish Language", "criminal; guilty; sinful", and thus "Cennc(h)airech" may be  translated "Sinful Head". Career. Amlaíb is mentioned by name only in the "Annals of the Four Masters" and "Annals of Clonmacnoise". Historians believe the dating in both cases is off. In general, the sources for western Ireland's history are not great. The "Chronicon Scotorum" records several of the same and related events but does not mention Amlaíb by name. Annals of the Four Masters. The Annals of the Four Masters are generally off by two years. Capture or recruitment? The traditional interpretation of these notices, the second immediately following the first in the manuscripts, is that what Amlaíb mac  Gofraid was actually doing was compelling or recruiting Amlaíb Cenncairech for his upcoming battle with Athelstan of England. This was the Battle of Brunanburh. More recent historians tend to interpret this as the culmination of an extended conflict between the Norse of Dublin and Limerick, dating from the arrival of Tomrair mac Ailchi in 922. They assume that the two Amlaíbs actually engaged in a battle and that "mac Gofraid" won a "decisive victory" over Cenncairech, effectively ending Limerick as a major player in Ireland for the next two or three decades. Annals of Clonmacnoise. It is uncertain but likely  that Cenncairech soon succeeded Colla ua Bairid, who died in 932, as King of the Limerick Norse, and thus it is likely he was involved in the events of 933. Again the expedition to England follows, but here no mention is made of any conflict with Dublin. Chronicon Scotorum. Again here no mention is made of any conflict with Dublin. Irish saga. A certain Amlaíb of Limerick features as a character in the 12th century saga and propaganda tract "Caithréim Chellacháin Chaisil", who is killed by Cellachán Caisil himself. Alexander Bugge takes no position regarding his historicity, but offers Amlaíb  Cenncairech as his primary example of an historical Amlaíb associated with Limerick. Donnchadh Ó Corráin allows that "The Amlaíb of the text may be a vague memory of Amlaíb Cennchairech but it must be remembered that Amlaíb is one of the commonest Viking names in Ireland." Bugge does believe that this Amlaíb of Limerick can be identified as the father of the Amlaíb mac Amlaíb mentioned in the "Cogad Gáedel re Gallaib" as an ally of Ivar of Limerick. According to this saga and propaganda tract (dated near contemporary with the "Caithréim Chellacháin Chaisil"), Amlaíb mac Amlaíb was banished along  with Ivar following the Norse loss at the Battle of Sulcoit against the Dál gCais led by Mathgamain mac Cennétig in 967. The two are said to have "attempted the conquest of Britain" together, apparently without success, as Amlaíb "was killed by the king of Britain" and Ivar soon after reestablished himself in Limerick.
