of túatha headed by an overking drawn from
the Uí Briúin Bréifne.
By the 11th century, Bréifne was controlled by
Ruairc (O'Rourke) dynasty. The
Breifne kingdom reached the height of its power in 1200s under Tigernán Ua Ruairc.

1172 was followed by a succession dispute, and a conflict between the Ua Ruairc and Ua
Kingdoms - Following the Battle of Magh Slecht in 1256, Bréifne split into West

In about 800 AD, The lesser
Longford, O’Rourke and family, made claim
on the throne of Breifne. A feud and war continued for two hundred years between O’Reilly and O’Rourke
with various success on both sides. Eventually the High Irish King at the council of the Kings divided
Breifne in two: East and West.
O’Reilly continued to rule the Kingdom of Breifne East, with the greater population and access to the sea
port of Drogheda while O’Rourke was granted the Kingdom of West Breifne, land bound portion of the western area of
County Meath, now known as Westmeath. O'Rourke submitted to the crown and the crown granted many of
