Life story

Family Background

Maurice FitzGerald was born around 1194 in Ireland, son of Gerald FitzMaurice, 1st Lord of Offaly, and Eve de Bermingham. He succeeded to the lordship on his father's death in 1204 and was knighted in July 1217. He married Juliana de Grenville, with whom he had four sons, including Maurice, who succeeded him as 3rd Lord of Offaly.

Justiciar of Ireland

Appointed Justiciar of Ireland in September 1232, Maurice held the office for thirteen years, enforcing royal authority so aggressively that Henry III himself complained in February 1235 that Maurice was "little pleasant, nay, beyond measure harsh in executing the King's mandates." He was eventually dismissed in 1245 over tardiness supporting a Welsh campaign, succeeded by John FitzGeoffrey.

Military Campaigns

Maurice campaigned repeatedly against Irish kings throughout his career: he helped subjugate Connacht in 1235, invaded Tír Chonaill in 1247 and won the Battle of Ballyshannon, where three prominent Irish lords reportedly fell, and fought Gofraidh Ó Domhnaill at the Battle of Credan in 1257.

Religious Foundations and the Richard Marshal Controversy

Maurice founded South Abbey, Youghal in 1224 — one of the earliest Franciscan friaries in Ireland — and later the Dominican Abbey at Sligo, in part as atonement after rumors connected him to the death of Richard Marshal at the Battle of the Curragh in 1234; Maurice traveled to London and swore before Henry III that he was innocent. His piety earned him the nickname "an Brathair," the Friar.

Death

In 1257 Maurice fought Gofraidh Ó Domhnaill in single combat at the Battle of Credan; both men were gravely wounded, and Maurice died of his injuries at Youghal Monastery on May 20, 1257, wearing a Franciscan habit. The Irish Annals of the Four Masters remembered him starkly as "destroyer of the Irish."
