high-kingship, Domnall Mac Lochlainn, King of Cenél nEógain. It possible that this compact contributed to Godred's successes in Dublin. Just as Godred's seizure of Dublin appears to have taken place at a point when two superior powers were occupied elsewhere, his expulsion from the kingdom appears to have taken place at a time when Muirchertach's hands were free, having temporarily settled matters with his rival half-brother, Diarmait Ua Briain, and having earned some success in extending Uí Briain authority into Connacht. Contemporary numismatic material concerning Dublin indicates that, starting in 1095, immediately following Godred's demise, the kingdom's coinage became drastically debased in terms of weight and stylistic quality. For about a generation previous, Dublin's coinage had imitated the near contemporary styles of the English and Anglo-Normans, albeit with varying consistency, but immediately after 1095 Dublin's coins dramatically degenerated into poor imitations of nearly century-old designs. This could be evidence that, in comparison to Muirchertach's immediate Norse-Gaelic predecessors in Dublin, his own regime lacked the expertise to ensure the vitality of the kingdom's commerce and currency. Annalistic evidence from throughout Europe indicates that the continent suffered from a resurgence of plague and famine during the first years of the 1090s. In fact, if the Annals of the Four Masters is to be believed, about a quarter of Ireland's population succumbed to pestilence in 1095. This source, and a host of others—such as the Annals of Clonmacnoise, the Annals of Inisfallen, the Annals of Tigernach, and the Annals of Ulster—all single out Godred as one of the many mortalities. The Chronicle of Mann, which also records Godred's death, reveals that he died on Islay. The fact that he met his end on that island could be evidence that Muirchertach not only drove him from Dublin, but from Mann as well. On the other hand, the possibility that Islay was an important locus of royal power in the Isles, combined with the evidence of his father's links with the island could instead be evidence against such an overthrow. Furthermore, the chronicle itself states that Godred was succeeded by his eldest son, Lagmann. On Godred's death, the Annals of Inisfallen accord him the title "" (translated variously as "King of Dublin and of the Isles" and "king of Dublin and the Hebrides", a remarkable designation in the fact that it is quite rare, and perhaps only elsewhere accorded to Diarmait mac Maíl na mBó.
