Máel Gualae
Irish king

Máel mac Donngaile (died 859), known as Máel Gualae, was a King of Munster from the Eóganacht Chaisil branch of the Eoganachta, the ruling dynasty of Munster. He was of the Clann Faílbe sept of this branch and a grandson of Tnúthgal mac Donngaile (died 820), whom some sources name as King of Munster and brother of Áilgenán mac Donngaile (died 853), also King of Munster. His branch of the ruling dynasty had their lands in the Cashel area of modern County Tipperary. He reigned from 856 to 859.
After the death of Áilgenán in 853 there was an interregnum until the succession of his brother Máel Gualae in 856. The Danes had arrived in Ireland in 849 and took control of Dublin in 851. The dispersed Norse went off to plunder different areas of Ireland and a rivalry began between these two Viking groups with Irish kings using this rivalry in their own conflicts. A number of men in Munster joined up with these Norse and were known as Gall Gaedil ("foreign Gaels"). Cerball mac Dúnlainge (died 888), King of Osraige aligned himself with the Danes versus the Norse to become the most powerful ruler in southern Ireland during this period.
During the interregnum, the High King of Ireland Máel Sechnaill mac Máele Ruanaid (died 862) of Clann Cholmáin led an expedition into Munster in 854 as far as the borders of the Déisi in Tipperary County and took hostages from Munster.

Why this record matters
“Máel Gualae” is worth following because a concise public description often conceals a longer documentary argument. Here, Máel, Gualae and Irish provides the most credible route into that argument.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 9, 2024. The linked authority identifier is Q6949538. None of the 0 selected statements returned an explicit reference.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
