Elizabeth I inherited England's crown in 1558 after the death of Mary I and worked with advisers including William Cecil to stabilize the monarchy. The religious settlement of 1559 restored royal authority over the church and established Protestant worship through the Acts of Supremacy and Uniformity. It preserved some traditional forms but required conformity, creating lasting conflict with Catholics and with Protestants who sought more extensive reform.

Marriage and succession remained central political questions. Elizabeth considered foreign and English candidates but never married, using negotiations as instruments of diplomacy while avoiding a consort's competing authority. Her cousin Mary, Queen of Scots, offered an alternative claim and became the focus of Catholic hopes after seeking refuge in England in 1568.

Elizabeth contained the Northern Rebellion of 1569 and faced heightened danger after Pope Pius V excommunicated her in 1570. Plots, foreign intervention, and the activities of missionary priests prompted increasingly severe measures against Catholics. Mary Stuart remained in custody until her involvement in a conspiracy led to trial and execution in 1587.

In foreign affairs, Elizabeth usually sought economy and limited commitments, but deteriorating relations with Spain drew England toward wider war. Support for rebels in the Netherlands, maritime attacks on Spanish interests, and competition in Atlantic ventures intensified the conflict. The Spanish Armada failed in 1588 through English resistance, logistical difficulties, and destructive weather. War nevertheless continued, involving costly operations and defeats as well as celebrated victories. English intervention in Ireland culminated in a brutal struggle against Hugh O'Neill and his allies during the Nine Years' War.

Her reign coincided with expanding overseas commerce, colonizing ventures, and a remarkable flowering of drama and poetry. Royal patronage and licensing shaped cultural life, though Shakespeare and other writers worked within institutions beyond the court. Poverty, harvest failures, monopolies, and wartime taxation strained the final decades. The rebellion of her former favorite the Earl of Essex failed in 1601. Elizabeth died in 1603, and James VI of Scotland succeeded her as James I of England. Her political longevity helped consolidate the Tudor religious settlement, while the coercion and imperial ambitions of her reign remain integral to its assessment.
