Queen Mary I died on 1558-11-17, and Elizabeth Tudor became queen of England and Ireland. Her accession immediately raised major questions about religion, foreign policy, and the royal succession because Elizabeth was Protestant and unmarried.
Elizabeth’s coronation took place at Westminster Abbey on 1559-01-15. The ceremony helped confirm her authority after a contested succession and signaled that the new reign would steer England away from Mary I’s restoration of Roman Catholicism.
In 1559, Parliament passed the Acts of Supremacy and Uniformity as the core of the Elizabethan Religious Settlement. Together, they restored royal authority over the Church of England and required a common form of worship using the Book of Common Prayer, aiming for a workable national compromise after years of upheaval.
The Treaty of Edinburgh was concluded on 1560-07-06 after fighting around Leith, where French forces had supported the regency in Scotland. The treaty helped reduce the immediate risk of a France-Scotland front against England and strengthened ties with Protestant leaders in Scotland.
Mary, Queen of Scots returned from France and arrived in Scotland in August 1561, re-entering Scottish politics as a Catholic monarch in a country that had moved strongly toward Protestantism. Her presence also mattered in England because many Catholics viewed Mary as a stronger claimant to the English throne than Elizabeth.
After civil conflict in Scotland, Mary crossed into England in May 1568 and was taken to Carlisle Castle, beginning a long captivity under Elizabeth’s authority. This turned the succession question into a security crisis, since plots against Elizabeth often centered on freeing Mary and placing her on the English throne.
From late 1569 into early 1570, leading northern nobles launched a Catholic rebellion that aimed to replace Elizabeth with Mary, Queen of Scots. The revolt failed, but it hardened the government’s approach toward internal threats and underscored how religion and succession could combine into open rebellion.
On 1570-02-25, Pope Pius V issued the bull Regnans in Excelsis, excommunicating Elizabeth and encouraging her subjects to withdraw loyalty. The declaration increased fears of Catholic-backed plots and helped drive tighter laws and surveillance aimed at protecting the queen and the Protestant settlement.
The Thirty-Nine Articles were revised and finalized in 1571, providing a more settled statement of Church of England doctrine. They helped define English Protestant belief while leaving some wording broad enough to keep a national church together during ongoing religious disagreement.
In 1571, the Ridolfi Plot sought to remove Elizabeth and place Mary, Queen of Scots on the throne, with foreign support. The plot’s discovery intensified government suspicion toward Catholic networks and reinforced the idea that threats could be both domestic and international.
On 1585-08-10, Elizabeth signed the Treaty of Nonsuch with the Dutch rebels fighting Spain. This marked a major escalation in conflict with Spain, moving England from limited support toward more direct military involvement in the wider European religious and power struggle.
In 1586, the Babington Plot planned Elizabeth’s assassination and aimed to put Mary, Queen of Scots on the English throne. The plot was uncovered through intelligence work, and it provided the evidence used to convict Mary for treason, setting the stage for her execution.
Mary was executed by beheading on 1587-02-08 after being found guilty of treason connected to the Babington Plot. Her death removed a focal point for succession-based conspiracies but also worsened relations with Catholic powers, especially Spain.
In July–August 1588, Spain launched the Armada to support an invasion of England, but English naval resistance and severe weather disrupted the plan. The failure was a turning point in the Anglo-Spanish War, boosting English confidence and shaping later English emphasis on sea power.
Elizabeth died on 1603-03-24 after reigning for more than 44 years. With no direct heir, the crown passed to James VI of Scotland (as James I of England), uniting the English and Scottish crowns and closing the Tudor era.
