Catherine of Aragon in the context of "Thomas Cromwell"

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.

Henry VIII (28 June 1491 – 28 January 1547) was King of England from 22 April 1509 until his death in 1547. Henry was a dominant and forceful monarch. He is also known for his six marriages and his efforts to have his first marriage, to Catherine of Aragon, annulled. His disagreement with Pope Clement VII about such an annulment led Henry to initiate the English Reformation, separating the Church of England from papal authority. He appointed himself Supreme Head of the Church of England and dissolved convents and monasteries, for which he was excommunicated by the pope.

Born in Greenwich, Henry brought radical changes to the Constitution of England, expanding royal power and ushering in the theory of the divine right of kings in opposition to papal supremacy. He frequently used charges of treason and heresy to quell dissent, and those accused were often executed without a formal trial using bills of attainder. He achieved many of his political aims through his chief ministers, some of whom were banished or executed when they fell out of his favour. Thomas Wolsey, Thomas More, Thomas Cromwell, and Thomas Cranmer all figured prominently in his administration.

Sir Thomas More (7 February 1478 – 6 July 1535), venerated in the Catholic Church as Saint Thomas More, was an English lawyer, judge, social philosopher, author, statesman, theologian, and noted Renaissance humanist. He also served Henry VIII as Lord Chancellor from October 1529 to May 1532. He wrote Utopia, published in 1516, which describes the political system of an imaginary island state.

More opposed the Protestant Reformation, directing polemics against the theology of Martin Luther, Huldrych Zwingli and William Tyndale. More also opposed Henry VIII's separation from the Catholic Church, refusing to acknowledge Henry as supreme head of the Church of England and the annulment of his marriage to Catherine of Aragon. After refusing to take the Oath of Supremacy, he was convicted of treason on what he stated was false evidence, and was executed. At his execution, he was reported to have said: "I die the King's good servant, and God's first."

Anne Boleyn (/ˈbʊlɪn, bʊˈlɪn/; c. 1501 or 1507 – 19 May 1536) was Queen of England from 1533 to 1536, as the second wife of King Henry VIII. The circumstances of her marriage and execution, by beheading for treason, made her a key figure in the political and religious upheaval that marked the start of the English Reformation.

Anne was the daughter of Thomas Boleyn (later Earl of Wiltshire), and his wife, Elizabeth Howard, and was educated in the Netherlands and France. Anne returned to England in early 1522, to marry her cousin James Butler, 9th Earl of Ormond; the marriage plans were broken off, and instead, she secured a post at court as maid of honour to Henry VIII's wife, Catherine of Aragon. Early in 1523, Anne was secretly betrothed to Henry Percy, son of Henry Percy, 5th Earl of Northumberland, but the betrothal was broken off when the Earl refused to support it. Cardinal Thomas Wolsey refused the match in January 1524.

Thomas Wolsey (/ˈwʊlzi/ WUUL-zee; c. March 1473 – 29 November 1530) was an English statesman and Catholic cardinal. When Henry VIII became King of England in 1509, Wolsey became the king's almoner. Wolsey's affairs prospered and by 1514 he had become the controlling figure in virtually all matters of state. He also held important ecclesiastical appointments. These included the Archbishop of York—the second most important role in the English church—and that of papal legate. His appointment as a cardinal by Pope Leo X in 1515 gave him precedence over all other English clergy.

The highest political position Wolsey attained was Lord Chancellor, the king's chief adviser (formally, as his successor and disciple Thomas Cromwell was not). In that position, he enjoyed great freedom and was often depicted as the alter rex ("other king"). After failing to negotiate an annulment of Henry's marriage to Catherine of Aragon, Wolsey fell out of favour and was stripped of his government titles. He retreated to York to fulfil his ecclesiastical duties as archbishop, a position he nominally held but had neglected during his years in government. He was recalled to London to answer to charges of treason—charges Henry commonly used against ministers who fell out of his favour—but died from natural causes on the way.

The title of Supreme Head of the Church of England was created in 1531 for King Henry VIII when he first began to separate the Church of England from the authority of the Holy See and allegiance to the papacy, then represented by Pope Clement VII. The Act of Supremacy of 1534 confirmed the King's status as having supremacy over the church and required the nobility to swear an oath recognising Henry's supremacy. By 1536, Henry had broken with Rome, seized assets of the Catholic Church in England and Wales and declared the Church of England as the established church with himself as its head. Pope Paul III excommunicated Henry in 1538 over his divorce from Catherine of Aragon.

Similarly, in Ireland, the Parliament of Ireland passed the Act of Supremacy (Ireland) 1537, establishing Henry as Supreme Head of the Church of Ireland. Again Henry seized assets of the Catholic Church in Ireland and declared the Church of Ireland as the established church with himself as its head. He made himself King of Ireland in 1541, which reinforced his status (previous English kings had held the title of Lord of Ireland, and the island was considered a papal fief based on an 1155 papal bull).
