King Malachy I.

Malachy I. (Maelseachlainn), Monarch of Ireland, reigned, according to the Four Masters, from 845 to 860. Before his accession he compassed the assassination of Turgesius, a Dane, and the expulsion of the Northmen from Ireland; but they returned in force before long, and his reign was marked by constant descents and depredations of the Dubh-Lochlannaigh (Black Scandinavians, or Danes), and Finn-Lochlannaigh (White Scandinavians, or Norwegians). His reign was also notable for a regal convention which he called at Rathhugh, in the present County of Westmeath.
