Justiciar of Ireland

The king's governor in Ireland: he keeps the king's peace, hears pleas, leads the host, commands the royal castles and cities and answers for the revenues.

The king reserves to himself pleas touching the crown, the mint and the exchange. Meiler is a soldier of the first invasion and a Geraldine cousin of half the colony, but he is John's man before anyone's, and his rule will be a long struggle with the great liberty-holders.

Who he is

Name
Meiler FitzHenry (Meilyr fitz Henry)
Title
Justiciar of Ireland (justiciarius Hibernie)
Since
About 1198 or 1199 (not pinned to the month); reappointed by John in June 1200
Born
About 1160 (not pinned)
Family
Son of Henry FitzHenry, a bastard son of Henry I by Nest of Deheubarth, so John's cousin and a kinsman of the FitzGeralds, Robert FitzStephen, Raymond le Gros and Gerald of Wales. Married about 1182 a niece of Hugh de Lacy; a son, also Meiler.
Confidence
medium

One of the first invaders (1169). Holds the office until 1208. His predecessor Hamo de Valognes (justiciar from about 1196-97) quarrelled with Archbishop Cumin in 1197; Hamo is out of office by 1200, when he becomes sheriff of Cambridgeshire and Huntingdonshire.

Overlord

King John

What it holds

  • Command of the royal castles and cities
  • The justiciar's court at Dublin and on eyre
  • Custody of escheats and wardships in the king's hand
  • Leadership of the royal host in Ireland

How it was acquired

Royal appointment; reappointed June 1200.

Allies and rivals

Close to John and to William de Burgh at first; wary of John de Courcy, 'a constant source of trouble'; later the open enemy of William Marshal and the Lacys (1207-08).

How things stand that morning

In office on 1 January 1200 (medium confidence: the old Dictionary of National Biography puts his appointment about 1198; the modern entry on Hamo de Valognes has Hamo in office until 1199). Either way the justiciar that winter is Meiler or, at the very latest, a Hamo about to hand over.

Wealth

The perquisites of office; his own lands in Leix and Meath (see Leix (Meiler)).

Military

The royal host, the castle garrisons and his own Geraldine kin and retainers. No figures.

Threats

  • The Connacht war drawing the colony's barons into private wars
  • John de Courcy in Ulster
  • The liberty-holders' resentment of royal officers

What the year holds

What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

  1. 1200 (not pinned)Meiler and the English of Leinster besiege Clonmacnoise against Cathal Carrach and plunder its stores (Four Masters, 1200).Depends on: The Connacht war crossing the Shannon Stopped by: Peace in Connacht
  2. June 1200With John in Normandy; reappointed justiciar.Depends on: John's favour Stopped by: Disgrace
  3. 28 October 1200Granted two cantreds in Kerry and one in Cork.Depends on: Royal favour Stopped by: Disgrace

Places of note

  • Dublin, seat of the justiciar: The justiciar's court; no royal castle yet (John orders one in 1204)

Where the sources disagree

  • The date of the change from Hamo de Valognes to Meiler is uncertain in the sources (about 1198 against 1199). The brief asks for it to be dated: we can only bracket it, late 1198 to late 1199.

Evidence: Office and reappointment are documented; the start date is not pinned.

On the map: An office over the whole lordship; not drawn.
