Pope Pius V Excommunicates Queen Elizabeth I

Context

By the mid-sixteenth century the Protestant Reformation had fractured Western Christendom, and England’s religious path diverged sharply from Rome. Henry VIII’s break with the papacy in the 1530s was followed by Edward VI’s more radical reforms and Mary I’s brief Catholic restoration; Elizabeth I’s accession in 1558 produced the 1559 Acts of Supremacy and Uniformity, which re-established royal control over the Church of England and required clergy and officials to swear an oath acknowledging her as Supreme Governor.

What Happened

In Rome, English Catholic exiles provided testimony against the queen. On 5 February 1570 formal proceedings opened before the papal curia. Twenty days later, on 25 February, Pope Pius V signed Regnans in Excelsis at St. Peter’s, branding Elizabeth “the pretended Queen of England and servant of crime,” a heretic who had usurped ecclesiastical authority, suppressed Catholic worship, and promoted Protestant doctrine. The bull released all her subjects from any oath of loyalty and forbade them to obey her laws or commands on pain of the same excommunication.

Aftermath

Copies of the bull reached England only in secret and produced little immediate rebellion. Most English Catholics continued to attend the established church or practiced their faith privately to avoid treason charges. The government responded by tightening enforcement of the oath of supremacy and treating the bull as evidence of foreign interference.

Legacy

The excommunication underscored the declining ability of the papacy to dictate political outcomes in an age of consolidating nation-states. It hardened the Protestant identity of the Elizabethan regime, contributed to the long Anglo-Spanish confrontation that culminated in the Armada of 1588, and left English Catholics under permanent suspicion as potential agents of foreign powers.
