Source-derived summary

The King of Mann (Manx: Ree Vannin) was the title taken between 1237 and 1504 by the various rulers, both sovereign and suzerain, over the Kingdom of Mann – the Isle of Man which is located in the Irish Sea, at the centre of the British Isles. Since 1504, the head of state has been known as the Lord of Mann.

Kingdom of Mann and the Isles (836–1237)

See Kingdom of the Isles and List of rulers of the Kingdom of the Isles

After the emergence of Somerled and his descendants in the 12th century, the Manx kings began to lose territory and power in the Hebrides. Before the reigns of the three sons of Olaf the Black, the Manx kings styled themselves "King of the Isles". By the time of the reigns of Olaf's sons, the kings had begun to style themselves "King of Mann and the Isles".

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “King of Mann”, the useful work is to connect “wikimedia list article” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 11, 2026. The linked authority identifier is Q304551. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1237, 1504, 1005 and 1014.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
