Aonghus Mór
Scottish magnate

Aonghus Mór mac Domhnaill (died c. 1293) was a leading figure in the thirteenth-century kingdoms of the Isles and Scotland. He was a son of Domhnall mac Raghnaill, the eponym of Clann Domhnaill, a branch of Clann Somhairle. Aonghus Mór appears to have succeeded his father in the mid part of the thirteenth century. At the time, the rulers of the Isles were fiercely independent of the Scottish Crown, and owed nominal allegiance to the distant Norwegian Crown. Aonghus Mór's first certain appearance in the historical record seems to evince his involvement in aiding native Irish kindreds against the consolidation of Anglo-Irish authority in the north-west of Ireland. Such cooperation could have been undertaken in the context of overseas kindreds like Clann Domhnaill constructing Irish alliances to gain assistance against Scottish encroachment.
Scottish aggression against the Isles seems to have precipitated the Norwegian Crown's campaign against the Scots in 1263. Like other leading members of Clann Somhairle, Aonghus Mór supported the Norwegian cause against Alexander III, King of Scotland. However, the fact that Hákon Hákonarson, King of Norway had to force Aonghus Mór's submission, suggests that his support was rendered somewhat grudgingly.
This brief starts where responsible research should: with the source description of “Aonghus Mór” as scottish magnate. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as scottish magnate. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 27, 2026. The linked authority identifier is Q1967485. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1293 and 1263.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
