For some years Mahon reigned undisputed King of Munster, but his successes only stimulated the jealousies of Molloy and the other Eugenian chiefs, who saw their race reduced to play an inferior part. They accordingly conspired with Ivar, and Molloy procured the treacherous murder of Mahon. The crime was useless, for Brian was left, and he immediately succeeded both to the leadership of his own tribe and to the kingdom of Munster, Molloy having certainly forfeited all moral claim to the alternate succession. Brian pursued the Danes to their strongholds, slew Ivar and his sons, and carried off the women and the treasure. There was, however, still a Scandinavian settlement at Limerick, and we find a grandson of Ivar afterwards in Brian's service as one of the ten Danish stewards whom he employed. He was ambitious, and he had experience of the skill of such officers in extorting contributions from unwilling subjects. Molloy and his chief allies were slain; and Brian, having reduced the Limerick Danes to insignificance, turned his arm against those of Waterford, whose territory he ravaged, and whose Celtic allies, inhabiting the modern county of Waterford, he easily subdued. Brian was acknowledged as supreme in Munster, and took security from the principal churches not to give sanctuary to thieves or rebels. As the consequence of further expeditions Leinster also became tributary; and thus, in eight years after his brother's death, Brian was admitted to be supreme in the southern half of Ireland. [Sidenote: Brian aims at being King of all Ireland.] In his further expeditions, undertaken with a view of becoming King of all Ireland, the Danes of Waterford sometimes accompanied Brian; but his progress towards the desired goal was arrested for a while by a prudent treaty with Malachi II., head King of Ireland, whom he acknowledged as undisputed sovereign of the northern half, and by a revolt of the Leinster men, who were allied with the Danes of Dublin, the united forces of Brian and Malachi having overthrown the Leinster Danes at Glenmama, near Dunlavin, Dublin fell an easy prey. The spoils taken are represented as enormous, and the mention of carbuncles and other precious stones, of buffalo-horns, goblets, and many-coloured vestures, betoken some degree of luxury and much commercial activity among the Danes. It is to be observed that Brian and his followers, though Christians, had no scruple about making slaves. His panegyrists simply say that the Danes by their cruelty and oppression had deserved no better treatment. Threshing and other rough work was done by the male prisoners. Menial work, including the severe labour of the hand-mill, was done by the women. 'There was not,' we are told, 'a winnowing sheet from Howth to the furthest point of Kerry that had not a foreigner in bondage on it, nor was there a quern without a foreign woman.' The fairer and more accomplished of the Danish women of course underwent the fate of Chryseis.
