Ua Briain ... pursued a vigorous foreign policy which was to carry his activities beyond his own shores.</p></blockquote> <p>In the latter regard, Candon (1979, p. 415) views </p> <blockquote><p>Ua Briain's activities in the Irish Sea area [as] a mixture of old and new, of pragmatism and idealism ... But they are invested with a modern purpose. Ua Briain makes one marriage with the king of <a href="/wiki/Norway" title="Norway">Norway</a>, and another with one of the most powerful non-royal families in Europe; he treats with the king of <a href="/wiki/Scotland" title="Scotland">Scotland</a>; his aid to the <a href="/wiki/Welsh_people" title="Welsh people">Welsh</a> princes acts as a stabilising influence in Welsh politics; he incurs trade sanctions from the king of England, and negotiates their suspension. Altogether, Muirchertach Ó Briain lifted his head above the domestic power struggle and sought to involve Ireland in the international politics of Europe, so that some sixty years later, these activities were still well remembered, and are reflected in the <i><a href="/wiki/Vitae" class="mw-redirect" title="Vitae">vitae</a></i> of St. <a href="/wiki/Flannan" class="mw-redirect"
