Source-derived summary

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. He was the son of Matad, Mormaer of Atholl, and Margaret, daughter of Earl Haakon Paulsson of Orkney. Of mixed Norse and Gaelic blood, and a descendant of Scots kings, he was a significant figure in northern Scotland, and played a prominent part in Scottish politics of the twelfth century. The Orkneyinga Saga names him one of the three most powerful Earls of Orkney along with Sigurd Eysteinsson and Thorfinn Sigurdsson.

Background

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. Thus the succession of the earldom was of great interest to the Scots king David I. 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. 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.

Harald Maddadsson was born shortly before Rognvald Kali Kolsson took control of the Earldom of Orkney, on the disappearance of Earl Paul Haakonsson. The Orkneyinga Saga reports the official tale, that Paul had abdicated, and the rumour that he was killed on the orders of Harald's mother.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1134, 1206, 1139—that can be checked directly. The linked authority record independently contributes the date 1134-01-01. Its value is orientation rather than verdict, with Harald, Maddadsson and Earl providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Harald Maddadsson”, the useful work is to connect “earl of Orkney and Mormaer of Caithness” to the records capable of establishing context and consequence.

Evidence profile

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 Dec 22, 2025. The linked authority identifier is Q532643. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1134, 1206 and 1139.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
