Information about Lordship of Ireland.
The Lordship of Ireland (Irish: Tiarnas na hÉireann), sometimes referred to retroactively as Norman Ireland, was a period of feudal rule in Ireland between 1177 and 1542 under the King of England, styled as Lord of Ireland. The lordship was created as a Papal possession following the Norman invasion of Ireland in 1169–71. As the lord of Ireland was also the king of England, he was represented locally by a governor, styled between 1660–1922 as the Lord Lieutenant of Ireland.
Ostensibly, the lordship extended throughout all of Ireland. However, in reality, the king's rule only ever extended to parts of the island. Areas under English rule expanded and retreated over time. Many areas remained separate and outside English rule until the 16th century.
The fluid political situation and feudal system allowed a significant amount of practical autonomy for the Hiberno-Norman nobility, who carved earldoms out for themselves and had almost as much authority as some of the native Gaelic kings. The period was brought to a close by the creation of the Kingdom of Ireland in 1542.
