Ulster Rebellion
Archived: 15 October 2026
In October 1641, Catholic grievances over plantation, exclusion and religious constraints combined with Stuart political instability to trigger rebellion in Ireland. A planned seizure of Dublin Castle failed, but Sir Phelim O’Neill’s Ulster rising captured Dungannon and Charlemont. His proclamation professed loyalty to Charles I and protection for Protestants, while a later forged royal commission fuelled confusion. The conflict brought flight, plunder, killings, dispossession and winter hardship, alongside retaliatory violence. Testimony in the 1641 Depositions records crisis but requires critical reading. Fighting spread towards Dublin, Leinster and Munster, intensified English and Scottish political conflict, and left Ireland fractured without settlement.
