Henry VIII Declares Himself King of Ireland

What happened

Following a failed rebellion by the Earl of Kildare in the 1530s, the English crown moved to reassert direct control over Ireland rather than rule at arm's length through Anglo-Irish and Gaelic lords. On 18 June 1542, the Parliament of Ireland, meeting in Dublin, passed the Crown of Ireland Act, read aloud in both English and Irish, declaring that the King of England and his heirs and successors would from then on be Kings of Ireland rather than merely Lords of Ireland, the title English monarchs had held since Henry II's 1171 intervention. The Act granted Henry VIII, the first monarch to hold the new title, all the honors, prerogatives, and dignities belonging to an imperial king. Alongside the new title, Henry pursued a policy called surrender and regrant, under which Gaelic chieftains who surrendered their lands and swore loyalty to the crown had those lands returned to them along with English noble titles, an attempt to anglicize Ireland's fragmented lordships without full military conquest.

How we know

The Crown of Ireland Act survives as an actual statute passed by the Irish Parliament in 1542, preserved in the UK's historical statute record, and its passage and context are corroborated by contemporary Tudor administrative correspondence about the Kildare rebellion and its aftermath.
