Old Irish Kingdoms and Clans --
Old Irish Surnames
The Connachta, Eoghanact and Christian Kingdoms
Gaulish (French) and British missionaries arriving in the 5th and 6th
centuries, such as St, Patrick, Palladius, St. Secundinus, St. Iserninus,
St. Finnian, St. Enda and St. Auxilius, were to have a dramatic influence
on the religious and cultural future of Ireland. They established and
gradually strengthened Christianity in Ireland, and helped to establish a
'monastic' hierarchy which played a important role in the creation of
churches and monastic schools of learning which were to later have
far-ranging impact throughout Europe in the later centuries.
The dominence of the Gaelic septs, at least in the North, was continued throughout the 5th and 6th
centuries as reflected in the so-called Ard Ri (high kingship) of Ireland. Eochu
Mugmedón, the Ard Ri in the middle 4th century and great-great-great-great-grandson of Conn of the Hundred Battles, had fostered a
continued line of Kings for Ireland. From his sons sprang the powerful
Ui Niall (Ui Neill), Ui Briuin and Ui Fiachra line of kings of Ireland,
Ulster, Midhe and Connacht. His great-grandson Oilill Molt ruled as
High King for twenty years, followed by another great-grandson, Lughaidh,
who ruled for twenty five years. The high kingship was next held for
twenty-four years by Muircheartach, a great-great-grandson of Eochu
Mugmedón. The high kingship was to remain in this family for another
The ancestors of Oilioll Olum, a 3rd century king of Caisil (Munster),
were beginning to show their dominance in southwest Ireland. His ancestors
formed a federation of dynasties known as the Eoghanachta, who were to
eclipse the Erainn peoples in Munster by the 7th century. Meanwhile the Dal
Riata, who had earlier moved out of Munster into the northeast corner of
Ireland, extended their kingdom into what is now Argyll in Scotland. At
about the same time the Southern Ui Niaill, descendants of Niall of
the Nine Hostages in Connacht, were making their moves into
northern Laigin (Leinster province) as well as into other parts of
Connacht. The A.D. battle of Druim Derge was a pivotal Ui Niaill victory
which was to push back the northern boundaries of Leinster until the arrival
of the Cambro-Normans in 1169.
The Historical Period
By the latter 5th century Ireland officially begins to enter into it's historical period. The events of the day come to be more accepted by modern historians. The early names and location of Irish tribes become clearer. The Irish kingdoms, their chiefs and their genealogies begin to emerge from the mist of 'pre-history'. St. Patrick and others succeed in spreading the new religion and Christian churches and monasteries make their appearance.
Dendrochronologists studying oak trees preserved in Irish bogs discovered what they believe to be a disastrous climate event occuring in the late 530s A.D. It was a described as a disaster of catastrophic proportions, with indications of crop failures and widespread famine around the world. It was during this timeframe when plague spread throughout Europe, that dynasties began to collapse in China, Mexico and elsewhere, and that Christianity began to take a firm hold in Ireland. Within a generation of the climate disaster most of the monasteries that gave rise to the Golden Age of Irish Christianity were already in existence. Among these included the great monasteries of Durrow founded about 543-560 by St. Columba; of Clonmacnoise founded in 545 by St. Ciaran; of Clonfert founded about 547-559 by St. Brendan; of Bangor founded between 552-559 A.D.; and of Iona founded by St. Columba in 563 A.D.
