Harald Maddadsson (Old Norse: Haraldr Maddaðarson, Gaelic: Aralt mac Mataid) (c. 1134 – 1206) was Earl of Orkney and Mormaer of Caithness from 1139 until 1206.
Of mixed Norse and Gaelic blood, and a descendant of Scots kings,[1] he was a significant figure in northern Scotland, and played a prominent part in Scottish politics of the twelfth century.
[2] In the early twelfth century, the Earldom of Orkney, although weakened since the time of Earl Thorfinn, remained in control of Caithness and was dominant in Sutherland and parts of the Outer Hebrides.
The marriage of Matad and Margaret is believed to have taken place not long before 1134, shortly following David's suppression of a major revolt involving Mormaer Óengus of Moray, grandson of king Lulach, and Máel Coluim mac Alaxandair, the illegitimate son of David's brother Alexander, and the subsequent extension of royal power into the provinces of Moray and Ross.
[3] David's nephew William fitz Duncan was appointed to rule Moray, and it has been proposed that Matad, whose power lay in the Scottish kingdom's heartland of Atholl, may also have been granted authority in the new lands north of the Mounth, and that his marriage to Margaret, Haakons daughter, was arranged with this in mind.
[4] Harald Maddadsson was born shortly before Rognvald Kali Kolsson took control of the Earldom of Orkney, on the disappearance of Earl Paul Haakonsson.
It is said that Frakkok and her supporters had originally intended to advance the claims of Harald Haakon's son Erlend on Paul's death.
However, Matad and Margaret, with King David backing them, imposed the infant Harald Maddadson as joint ruler with Rognvald.
[6] In Harald's early years, when power was exercised jointly with Rognvald on his behalf by councillors chosen by King David, Orkney enjoyed relative stability, although the Saga contains the usual killings and burnings of the time, including the death of an Earl Valthjof who is otherwise unknown.
[10] Possibly as a result of Eystein's activities, King David granted half of Caithness to Harald's cousin, Erlend Haraldsson.
Of these enemies, those who were active in the north and west, where Harald's power was significant, were Somerled, king of Argyll and Hebrides (who married earl Harold's first cousin Ragnhild of the Isle of Man), the sons of Máel Coluim mac Alasdair, illegitimate son of King Alexander I, himself held prisoner at Roxburgh, the Meic Uilleim, the descendants of William fitz Duncan, and the MacHeths and dispossessed would-be Mormaers of Ross (who possibly were a branch of the ancient Loairn dynasty of Moray and claimants of its rights).
[15] Two years later the rebellion of Domnall, son of Máel Coluim mac Uilleim, broke out in Ross and Moray, and it is presumed that Earl Harald played a part in this.
Whether in revenge for the treatment of Bishop John, or to cow Harald, or because Thorfinn may have had some claim to the throne through his mother (the lady of Moray), he was blinded and castrated, dying soon later in prison.
Orkney and Shetland warriors (the Eyjarskeggjar), led by Harald's brother-in-law Olaf, fought on behalf of Sigurd Magnusson against King Sverre Sigurdsson.
In 1222 Earl Jon was implicated, indirectly, in the burning of Bishop Adam of Caithness in his hall at Halkirk by local farmers.
The writer of the Orkneyinga Saga reported that "The punishments by Alexander for the burning of the bishop, by mutilation and death, confiscation and outlawry from the land, are still in fresh memory".
All concerned set off to Norway, but a ship carrying Earl Jon, his supporters, and his kin, was lost at sea on the return voyage.
