in exchange for oaths of allegiance to the new Irish Crown; and consequently Henry acquired little if any of the wealth of the Irish houses. By the time of Henry's death (1547) around half of the Irish monastic houses had been suppressed; but many houses of friars continued to resist dissolution until well into the reign of Elizabeth I. Bishoprics During the English Reformation, the Church of Ireland suffered in its temporal affairs:"more than half the clerical property in the kingdom being vested in lay hands; but that of Ireland was in a manner annihilated. Bishopricks, colleges, glebes and tithes were divided without mercy amongst the great men of the time, or leased out on small rents for ever to the friends and relations of the incumbents. Many Irish bishopricks never recovered this devastation, as Aghadoe, Kilfenora and others. The Bishoprick of Ferns was left not worth one shilling. Killala, the best in Ireland, was worth only 300l. per annum; Clonfert, 200l.; the Archbishoprick of Cashel, 100l.; Waterford, 100l.; Cork, only 70l.; Ardagh, 1l. 1s. 8d.; and the rest at even a lower rate." Religious policy of Edward VI Henry's son Edward VI of England (1547–53) formally established Protestantism as the state religion, which was as much a religious matter as his father's reformation had been political. His reign only lasted for six years and his principal reform, the Act of Uniformity 1549, had much less impact in Ireland than in England. He abolished the crime of heresy in 1547. During his reign attempts were made to introduce Protestant liturgy and bishops to Ireland. These attempts were met with hostility from within the Church, even by those who had previously conformed. In 1551, a printing press was established in Dublin which printed a Book of Common Prayer in English. Religious policy of Queen Mary I Henry's and Edward's efforts were then reversed by Queen Mary I of England (1553–1558), who had always been Roman Catholic. On her ascent to the throne, Mary reimposed orthodox Roman Catholicism by the First and Second Statute of Repeal of 1553 and 1555. When some Episcopal sees in Ireland became vacant, clerics loyal to Rome were chosen by Mary, with the approval of the Pope. In other cases, bishops in possession of dioceses that had been appointed by her father, without the approval of the Pope, were deposed. She arranged for the Act of Supremacy
