 Ua Briain was certainly a formidable potential ally, having recently imposed his dominance over the kingdoms of Connacht, Leinster, Mide, and Dublin as well.In fact, it was through his conquest of the latter that Ua Briain had banished Lǫgmaðr's father from Ireland once and for all, and thereby secured control of Dublin's awesome naval power.In consequence of this predominance, the clause as stated by the chronicle—that Ua Briain was to provide the Isles with a regent from his own kin—may well have been a condition on his intervention, rather than a request of the Islesmen themselves.
