Royal assent to the Act of Supremacy

On 29 April 1559, Elizabeth I gave royal assent to the Act of Supremacy, re‑establishing the Church of England’s independence from Rome and naming the queen Supreme Governor of the Church of England.[2][7] This act revived and modified Henry VIII’s earlier assertion of royal supremacy, carefully phrased to ease theological objections while firmly denying papal jurisdiction.

The Act of Supremacy was central to the Elizabethan Religious Settlement. It required clergy and royal officials to swear an oath acknowledging the monarch’s authority over ecclesiastical matters, thereby binding loyalty to crown and church together.[2][14] For Elizabeth, a female ruler in a male‑dominated religious hierarchy, the title "Supreme Governor" rather than "Supreme Head" helped address concerns that a woman could not be head of the church while still effectively concentrating power in her hands.

Historically, the act’s significance lies in stabilizing English Protestantism and integrating it into the constitutional fabric of the realm. It provided a legal basis for subsequent reforms, including the 39 Articles and the enforcement of uniform worship, and it entrenched the idea that national churches could exist independently of papal control.[1][11] The settlement Elizabeth forged through this measure influenced church–state relations across Europe and shaped Anglican identity into the modern era. Her ability to balance doctrinal compromise with political authority in this act illustrates the nuanced religious leadership she exercised throughout her reign.
