Where 1533 fits
Why 1533 is special
The break with Rome followed rather than caused the excommunication. England had already legislated to stop appeals to the Pope, so the papal response confirmed a separation that had been enacted domestically first.

The break with Rome followed rather than caused the excommunication. England had already legislated to stop appeals to the Pope, so the papal response confirmed a separation that had been enacted domestically first.
- History
In 1533, the Act in Restraint of Appeals barred appeals to Rome, the legal step that separated the English church from papal authority (England).
- Law & regulation
England passed the Act in Restraint of Appeals before Rome excommunicated Henry VIII, which means the constitutional break preceded the religious one. The sequence matters for whether the Reformation in England is best read as doctrinal or jurisdictional.
