Religious persecution of Catholics in Ireland began under King Henry VIII (then Lord of Ireland) after his excommunication in 1533. The Irish Parliament adopted the Acts of Supremacy, establishing the king's ecclesiastical supremacy. Some priests, bishops, and those who continued to pray for the pope were tortured and killed. The Treasons Act 1534 caused any act of allegiance to the pope to be considered treason. Many were imprisoned on this basis.
