endowed him with ancestral claims to the Norse-Gaelic kingdoms to Dublin and the Isles. In the 1070s, he secured the kingship of the Isles through his conquest of Mann, and forcefully added Dublin to his realm in 1091. Guðrøðr's downfall came in 1094, when he was driven out of Ireland by the Uí Briain, and died the following year in the Hebrides. There is uncertainty concerning the political situation in the Isles in the last decade of the eleventh century. What is known for sure is that, before the end of the century, Magnús Óláfsson, King of Norway led a marauding fleet from Scandinavia into the Isles, seized control of the kingdom, and held onto power in the Irish Sea region until his death in 1103. According to the Chronicle of Mann, when Guðrøðr died in 1095, Lǫgmaðr succeeded him as his eldest son, and went on to reign for seven years. The numerical calculations and chronology of this source are suspect, and it is uncertain if Lǫgmaðr's reign began before Magnús' arrival, during Magnús' overlordship, or even after Magnús' death. One possibility is that Lǫgmaðr commenced his reign in the Isles immediately after his father assumed the kingship of Dublin in 1091. If so, this transfer of power would seem to evidence the eminent status of Dublin's kinship amongst the Norse-Gaelic elite. Despite the uncertainty surrounding the inception of his reign, the chronicle reveals that Lǫgmaðr faced continued opposition from within his own family in the form of an ongoing rebellion by his brother, Haraldr. Lǫgmaðr eventually overcame Haraldr, however, and is stated to have had the latter blinded and emasculated. Afterwards, if the chronicle is to be believed, Lǫgmaðr repented the cruelty that he had inflicted upon Haraldr, and remorsefully resigned his kingdom, before setting off to Jerusalem, where he died. Irish intervention Although the Chronicle of Man maintains that Lǫgmaðr voluntarily vacated his throne, there is reason to suspect that he was forced from power. In about 1096, the chronicle claims that the leading Islesmen sought assistance of Muirchertach Ua Briain, King of Munster, and petitioned him to provide a regent from his own kin to govern the kingdom until Lǫgmaðr's younger brother, Óláfr, was old enough to assume control. The chronicle's account could be evidence that, by about 1096, Lǫgmaðr faced a faction formed around his younger brother; and that, when this faction was unable to
