Supreme Head of the Church of England in the context of "Catherine of Aragon"

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.

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.

The dissolution of the monasteries, occasionally referred to as the suppression of the monasteries, was the set of administrative and legal processes between 1536 and 1541, by which Henry VIII disbanded all Catholic monasteries, priories, convents, and friaries in England, Wales, and Ireland; seized their wealth; disposed of their assets; destroyed buildings and relics; dispersed or destroyed libraries; and provided for their former personnel and functions.

Though the policy was originally envisaged as a way to increase the regular income of the Crown, much former monastic property was sold off to fund Henry's military campaigns in the 1540s. Henry did this under the Act of Supremacy, passed by Parliament in 1534, which made him Supreme Head of the Church in England. He had broken from Rome's papal authority the previous year. The monasteries were dissolved by two Acts of Parliament, those being the First Suppression Act in 1535 and the Second Suppression Act in 1539.

Thomas Cromwell (/ˈkrɒmwəl, -wɛl/; c. 1485 – 28 July 1540) was an English statesman and lawyer who served as chief minister to King Henry VIII from 1534 to 1540, when he was beheaded on orders of the King, who later blamed false charges for the execution.

Cromwell was one of the most powerful proponents of the English Reformation. As the King's chief secretary, he instituted new administrative procedures that transformed the workings of government. He helped to engineer an annulment of the King's marriage to Catherine of Aragon so that Henry could lawfully marry Anne Boleyn. Henry failed to obtain the approval of Pope Clement VII for the annulment in 1533, so Parliament endorsed the King's claim to be Supreme Head of the Church of England, giving him the authority to annul his own marriage. Cromwell subsequently charted an evangelical and reformist course for the Church of England from the unique posts of Vicegerent in Spirituals and Vicar-general (the two titles refer to the same position).
