'Magnus III' was the last recognized
King of Man.
Married
Mary of Argyll, daughter of the
Lord of the Isles.
Brother of Harald I and ascended the throne after interruption by more distant relatives, rivals.
With his death in
1265 the Norse Manx Dynasty ended and Scottish rule began.
His son
Godred VI later attempted restoration but failed.
''Rex Manniae et Insularum''
King of Man and the Isles
After
1217, Norwegian suzerainty became a reality and
Norway consequently came into collision with the growing power of
Scotland.
Finally, in
1261,
Alexander III of Scotland sent envoys to Norway to negotiate for the cession of
the isles, but their efforts led to no result. He therefore initiated hostilities which terminated in tactical victory for the Norwegians, but significant strategic victory for the Scots, at the often overstated scirmish of the
Battle of Largs in
1263. The failure of the Norwegians to achieve a major and decisive victory at
Largs ended their campaign for that year, and the subsequent death of
Haakon IV in the
Orkneys led to the ascension to the throne of his son
Magnus VI and the signing of the
1266 Treaty of Perth. The Treaty of Perth ceded the islands, including
Man, to Scotland in consideration of the sum of 4000
marks (known as "merks" in Scotland) and an annuity of 100 marks.
However, Scotland's rule over Man did not become firmly established till
1275, when the Manx under
Godred VI suffered defeat in the decisive
Battle of Ronaldsway, near
Castletown.
