Henry VIII in the context of "Trinity College Dublin"

Mary I (18 February 1516 – 17 November 1558), also known as Mary Tudor, was Queen of England and Ireland from July 1553 and Queen of Spain as the wife of King Philip II from January 1556 until her death in 1558. She made vigorous attempts to reverse the English Reformation, which had begun during the reign of her father, King Henry VIII. Her attempt to restore to the Church the property confiscated in the previous two reigns was largely thwarted by Parliament but, during her five-year reign, more than 280 religious dissenters were burned at the stake in what became known as the Marian persecutions, leading later commentators to label her "Bloody Mary".

Mary was the only surviving child of Henry VIII by his first wife, Catherine of Aragon. She was declared illegitimate and barred from the line of succession following the annulment of her parents' marriage in 1533, but was restored via the Third Succession Act 1543. Her younger half-brother, Edward VI, succeeded their father in 1547 at the age of nine. When Edward became terminally ill in 1553, he attempted to remove Mary from the line of succession because he supposed, correctly, that she would reverse the Protestant reforms that had taken place during his reign. Upon his death, leading politicians proclaimed their Protestant cousin, Lady Jane Grey, as queen instead. Mary speedily assembled a force in East Anglia and deposed Jane.

The Royal College of Physicians of London, commonly referred to simply as the Royal College of Physicians (RCP), is a British professional membership body dedicated to improving the practice of medicine, chiefly through the accreditation of physicians by examination. Founded by royal charter from King Henry VIII in 1518, as the College of Physicians, the RCP is the oldest medical college in England.

The RCP's home in Regent's Park is one of the few post-war buildings to be listed at Grade I. In 2016 it was announced that the RCP was to open new premises in Liverpool at The Spine, a new building in the Liverpool Knowledge Quarter. The Spine opened in May 2021.

Elizabeth I (7 September 1533 – 24 March 1603) was the Queen of England and Ireland from 17 November 1558 until her death. She was the last and longest reigning monarch of the House of Tudor. Her eventful reign, and its effect on history and culture, gave name to the Elizabethan era.

Elizabeth was the only surviving child of Henry VIII and his second wife, Anne Boleyn. When Elizabeth was two years old, her parents' marriage was annulled, her mother was executed, and Elizabeth was declared illegitimate. Henry restored her to the line of succession when she was 10. After Henry's death in 1547, Elizabeth's younger half-brother Edward VI ruled until his own death in 1553, bequeathing the crown to a Protestant cousin, Lady Jane Grey, and ignoring the claims of his two half-sisters, Mary and Elizabeth, despite statutes to the contrary. Edward's will was quickly set aside and the Catholic Mary became queen, deposing Jane. During Mary's reign, Elizabeth was imprisoned for nearly a year on suspicion of supporting Protestant rebels.

The English Renaissance was a cultural and artistic movement in England during the late 15th, 16th and early 17th centuries. It is associated with the pan-European Renaissance that is usually regarded as beginning in Italy in the late 14th century. As in most of the rest of Northern Europe, England saw little of these developments until more than a century later within the Northern Renaissance. Renaissance style and ideas were slow to penetrate England, and the Elizabethan era in the second half of the 16th century is usually regarded as the height of the English Renaissance. Many scholars see its beginnings in the early 16th century during the reign of Henry VIII. Others argue the Renaissance was already present in England in the late 15th century.

The English Renaissance is different from the Italian Renaissance in several ways. The dominant art forms of the English Renaissance were literature and music. Visual arts in the English Renaissance were much less significant than in the Italian Renaissance. The English period began far later than the Italian, which was moving into Mannerism and the Baroque by the 1550s or earlier.

Monarchical systems of government have existed in Ireland from ancient times. This continued in all of Ireland until 1949, when the Republic of Ireland Act removed most of Ireland's residual ties to the British monarch. Northern Ireland, as part of the United Kingdom, remains under a monarchical system of government.

The office of High King of Ireland effectively ended with the Anglo-Norman invasion of Ireland (1169–1171) in which the island was declared a fief of the Holy See under the Lordship of the King of England. In practice, conquered territory was divided amongst various Anglo-Norman noble families who assumed title over both the land and the people with the prior Irish inhabitants being either displaced or subjugated under the previously alien system of serfdom. Though the revolutionary change in the status quo was undeniable, the Anglo-Norman invaders would fail to conquer many of the Gaelic kingdoms of Ireland, which continued to exist, often expanding for centuries after, however none could make any viable claims of High Kingship. This lasted until the Parliament of Ireland conferred the crown of Ireland upon King Henry VIII of England during the English Reformation. Henry initiated the Tudor conquest of Ireland which ended Gaelic political independence from the English monarch who now held the crowns of England and Ireland in a personal union.

The English Reformation began in 16th-century England when the Church of England broke away first from the authority of the pope and bishops over the King and then from some doctrines and practices of the Catholic Church. These events were part of the wider European Reformation: various religious and political movements that affected both the practice of Christianity in Western and Central Europe and relations between church and state.

The English Reformation began as more of a political affair than a theological dispute. In 1527 Henry VIII sought an annulment of his marriage, but Pope Clement VII refused. In response, the Reformation Parliament (1529–1536) passed laws abolishing papal authority in England and declared Henry to be head of the Church of England. Final authority in doctrinal disputes now rested with the monarch. Though a religious traditionalist himself, Henry relied on Protestants to support and implement his religious agenda.

Protestants were executed in England under heresy laws during the reigns of Henry VIII (1509–1547) and Mary I (1553–1558), and in smaller numbers during the reigns of Edward VI (1547–1553), Elizabeth I (1558–1603), and James I (1603–1625). Most were executed in the short reign of Mary I in what is called the Marian persecutions. Protestant theologian and activist John Foxe described "the great persecutions & horrible troubles, the suffering of martyrs, and other such things" in his contemporaneously-published Book of Martyrs.

Protestants in England and Wales were executed under legislation that punished anyone judged guilty of heresy against Catholicism. Although the standard penalty for those convicted of treason in England at the time was execution by being hanged, drawn and quartered, this legislation adopted the punishment of burning the condemned. At least 280 people were recognized as burned over the five years of Mary I's reign by contemporary sources.

Catherine of Aragon (also spelt as Katherine,historical Spanish: Catharina, now: Catalina; 16 December 1485 – 7 January 1536) was Queen of England as the first wife of King Henry VIII from their marriage on 11 June 1509 until its annulment on 23 May 1533. She had previously been Princess of Wales while married to Henry's elder brother, Arthur, Prince of Wales, for a short period before his death.

Catherine was born at the Archbishop's Palace of Alcalá de Henares, and was the youngest child of Isabella I of Castile and Ferdinand II of Aragon. She was three years old when she was betrothed to Arthur, the eldest son of Henry VII of England. They married in 1501, but Arthur died five months later. Catherine spent years in limbo, and during this time, she held the position of ambassador of the Aragonese crown to England in 1507, the first known female ambassador in European history. She married Henry VIII shortly after his accession in 1509. For six months in 1513, she served as regent of England while Henry was in France. During that time the English defeated a Scottish invasion at the Battle of Flodden, an event in which Catherine played an important part with an emotional speech about courage and patriotism.

Edward VI (12 October 1537 – 6 July 1553) was King of England and Ireland from 28 January 1547 until his death in 1553. He was crowned on 20 February 1547 at the age of nine. The only surviving son of Henry VIII by his third wife, Jane Seymour, Edward was the first English monarch to be raised as a Protestant. During his reign, the realm was governed by a regency council because Edward never reached maturity. The council was first led by his uncle Edward Seymour, Duke of Somerset (1547–1549), and then by John Dudley, Duke of Northumberland (1550–1553).

Edward's reign was marked by many economic problems and social unrest that in 1549 erupted into riot and rebellion. An expensive war with Scotland, at first successful, ended with military withdrawal from Scotland and Boulogne-sur-Mer in exchange for peace. The transformation of the Church of England into a recognisably Protestant body also occurred under Edward, who took great interest in religious matters. His father, Henry VIII, had severed the link between the English Church and Rome but continued to uphold most Catholic doctrine and ceremony. During Edward's reign, Protestantism was established for the first time in England, with reforms that included the abolition of clerical celibacy and the Mass and the imposition of compulsory English in church services.
