Born and raised on de Bermingham lands in modern
County Offaly, John de Bermingham, like his father Peter de Bermingham, was a
Hiberno-Norman soldier. His military career was highlighted by his battles with the Irish, at a time when the
English presence in eastern Ireland was coming under increasing attacks from the Irish. After campaigns against the Irish of the
Slieve Bloom Mountains and his victory over
Edward Bruce at the
Battle of Faughart in 1318, ending the
Bruce Campaign in Ireland, de Bermingham was rewarded with lands in modern County Louth by the Lord Justiciar of Ireland. de Bermingham, like many other Norman lords, used levies of
kerns (Irish mercenaries) during conflicts and to defend their lands. However, de Bermingham rarely exercised control over the soldiers, who would often attack, rob or sometimes even murder his tenants. Another reason de Bermingham was despised by his tenants was that he often brought
Irish culture into the area, such as Gaelic harpists and other musicians. At this time, the area was on the frontier with
Gaelic Irish Kingdoms (particularly the MacMahons and O'Reillys) and suffered repeated attacks from them, mostly
cattle raids, but sometimes resulting in the massacre of civilians. This led to widespread discontent and anger with de Bermingham's lordship. == Massacre ==
