Note 404 — Chapter III · THE CONQUEST OF IRELAND. 795–1172.
Reading edition
Something of this kind must be meant by the phrase of the Four Masters (ib. p. 1095): “The foreigners made a year’s peace between Leath-Chuinn and Leath-Mhogha.” This is in 1150, after Murtogh’s appearance as “King of Ireland” and the Ostmen’s submission to Terence (II.) O’Brien, whom his namesake of Connaught had set up as king in Munster.
