Following an active 13th century, and after their move south the O'Donovans of Ui Chairbre fall into relative obscurity for approximately two centuries, primarily because the records for Munster during this period are few. Fragmenting into several smaller-sized lordships, they became subordinate to their overlord, MacCarthy Reagh, who was at odds with the MacCarthy Mor, who was at odds with the MacCarthys of Muscrery, who were at odds with both the Norman settlers (Barrys) and the old Irish (O'Callahan, O'Keefe), and with Gaelicized English (Fitzgeralds- Earls of Desmonds, FitzGibbons – Earls of Kildare and the White Knight), all of whom were or were not, depending on changing politics, at odds with the English monarchs.
