12 November 1216: Magna Charta Hiberniae was issued on this day. It was a follow up to the original Magna Carta from the previous year that King John of England was forced to issue at the behest of his Barons in order to placate them from Revolt.
MAGNA CHARTA HIBERNIAE
Henry, by the grace of God, King of England, Lord of Ireland, etc., to all his archbishops, bishops, abbots, earls, barons, justices, sheriffs, reeves, ministers, etc., and to all his faithful people, greeting.
Know that to the honour of God, the exaltation of Holy Church, and the amendment of our kingdom, by advice of Gualo, cardinal priest of St. Martin's, Legate of the Apostolic See, Peter, bishop of Winchester [and ten other bishops], William the Marshall, earl of Pembroke [and other earls and nobles], Hubert de Burgh, our justiciar, and others.
Firstly, we have granted to God, and by his present charter confirmed for us and our heirs for ever, that the Irish Church shall be free, and have all her rights entire and her liberties inviolable.
We have also granted to all free men of our kingdom, for us and our heirs for ever, all the liberties underwritten, to have and to hold to them and their heirs of us and our heirs.
