Pope Paul III Excommunicates King Henry VIII
In the early 16th century, England’s King Henry VIII sought to annul his marriage to Catherine of Aragon to marry Anne Boleyn and secure a male heir, clashing with papal authority over the matter. Henry declared himself Supreme Head of the Church of England in 1534, breaking from Rome. On December 17, 1538, Pope Paul III formally excommunicated Henry for these actions and his remarriage. The bull of excommunication cut Henry off from the Catholic Church and its sacraments. This intensified England’s religious schism and accelerated the English Reformation, leading to the dissolution of monasteries and the establishment of Protestant-leaning institutions under royal control.
