This Irish-language chronicle covers events in Ireland from the beginning of the eleventh to the end of the sixteenth centuries. Edited and translated by the native Irish speaker and acclaimed scholar William Hennessy (c.1829–89), the work was published for the Rolls Series in 1871 and remains an important source for Irish history. Hennessy also supplied an edited and translated excerpt from a closely related chronicle, The Annals of Connacht, to supplement years missing from the edited text (1316–1412). Volume 2, including a substantial index to both volumes, begins with an account of warfare among Gaelic-Irish and Anglo-Irish nobility in the fourteenth century and concludes shortly before the rebellion of Hugh O'Neill, Earl of Tyrone, in the 1590s.
