Seeds of the later Carbery kingdom began to develop in the 13th century. At 1200, the Uí Chairbre were primarily composed of and ruled by the Uí Donnobhains (now O'Donovans), occupying areas in their historical territory near Adare, Croom and Bruree. In both 1200 and 1205, MacCarthaigs are recorded as being in conflict with the Uí Chairbre. At that time the Carbery region was still ruled by the powerful
Eóganacht Raithlind in the form of the
O'Mahonys, and to a lesser but still notable extent by the even more ancient
Corcu Loígde in the form of the O'Driscolls. By 1232,
Donal Gott MacCarthy and his sons had effected a decisive conquest and effected a major change in their territory. During the remainder of the 13th century, infighting and splintering within the MacCarthaigs led to the establishment of several MacCarthy septs, with territories in Duhallow, Coshmaine, Muscrery and what would become the larger clan lands of MacCarthy Mor and MacCarthy Reagh. By 1283, one of the MacCarthy splinter groups (and which would ultimately become the sept of MacCarthy Reagh) was noted as being part of the Ui Chairbre, when Domnall (i.e. Domnall Óc, a.k.a. Donal Maol), son of Domnall Cairprech MacCarthaig (a.k.a. Donal Gott), and others of the Uí Chairbri made a treacherous plot against Domnall Mac Carthaig, king of Desmond. Ultimately though, the plot failed, and the Uí Chairbre fled, ultimately resettling in Carbery. However, in 1281 "peace was made by Domnall Óc Mac Carthaig, son of Domnall Cairprech, and by Feidlimid Mac Carthaig, with Domnall Ruad Mac Carthaig, king of Desmumu, and they submitted and gave hostages to him. And he gave them their share: Desmumu south of the Laí to Domnall Óc, Eóganacht Uí Donnchada save Longphort in Ríg, and much of Muscraige and Uí Chonaill to Feidlimid. And all were at war with the foreigners, and Cell Fhorglann was burned and its castle razed; and great forays were made there, and people slain by Donnchad Mac Carthaig, Tadc Ruad Mac Carthaig, the son of Gilla Mo-Chutu Ó Súilliubáin, and by many other nobles including the Uí Muirchertaig and Uí Donnchada." Hence from 1281 the MacCarthy Reagh dynasty continued as overlords of 'Desmond south of the Lee' until eventually forced to surrender to the English crown in 1606. The many movements of the clans during the 13th century resulted in the relocation of many of the septs in the area, including those of the O'Mahonys, O'Driscolls. The
O'Learys of ancient Rosscarbery, close kin to the O'Driscolls, retired northwards to Muskerry sometime around the year 1300. The source of the naming of the Carberry area has been debated by many scholars, with John O'Donovan arguing it came from the migration of the O'Donovans of Uí Chairbre (and who ignored the MacCarthaig element within the Uí Chairbre), and others, including
Canon John O'Mahony in his work ''History of the O'Mahony Septs'', arguing that the name derived from much earlier (circa 300 AD) rulers, and from whom descended the O'Driscolls and the O'Mahonys and which occupied the region from the 5th or 6th century AD onwards, in Late Antiquity. Beginning with the expansion of the MacCarthaig territory in a north east direction in 1259 as certain MacCarthaig septs recaptured a significant amount of land from the Normans, demolished a multitude of their castles, occupying others, and built a considerable string of their own fortresses, the territory of Carbery was expanded to as much as by 1500.
