Year 1536 (MDXXXVI) was a leap year starting on Saturday (link will display the full calendar) of the Julian calendar.

Anne Boleyn ( /ˈbʊlɪn/, /bəˈlɪn/ or /bʊˈlɪn/); c.1501 – 19 May 1536) was Queen of England from 1533 to 1536 as the second wife of Henry VIII of England and Marquess of Pembroke in her own right. Henry's marriage to Anne, and her subsequent execution, made her a key figure in the political and religious upheaval that was the start of the English Reformation. Anne was the daughter of Thomas Boleyn, 1st Earl of Wiltshire, and his wife, Lady Elizabeth Howard, and was educated in the Netherlands and France, largely as a maid of honour to Claude of France. She returned to England in early 1522, in order to marry her Irish cousin James Butler, 9th Earl of Ormond; however, the marriage plans ended in failure and she secured a post at court as maid of honour to Henry VIII's queen consort, Catherine of Aragon.

Early in 1523 there was a secret betrothal between Anne and Henry Percy, son of the 5th Earl of Northumberland. However, in January of 1524 Cardinal Thomas Wolsey broke the betrothal, Anne was sent back home to Hever Castle, and Percy was married to Lady Mary Talbot, to whom he had been betrothed since adolescence. In February/March 1526 Henry VIII began his pursuit of Anne. She resisted his attempts to seduce her, refusing to become his mistress as her sister Mary had. It soon became the one absorbing object of Henry's desires to annul his marriage to Queen Catherine so he would be free to marry Anne. When it became clear that Pope Clement VII would not annul the marriage, the breaking of the power of the Catholic Church in England began. In 1532, Henry granted her the Marquesate of Pembroke.

Catharine of Aragon (Castilian: Catalina de Aragón; Aragonese: Catarina d'Aragón) (16 December 1485 – 7 January 1536) was Queen consort of England as the first wife of King Henry VIII of England and Princess of Wales as the wife to Arthur, Prince of Wales. In 1507, she also held the position of Ambassador for the Spanish Court in England when her father found himself without one, becoming the first female ambassador in European history. For six months, she served as regent of England while Henry VIII was in France. During that time the English won the Battle of Flodden, an event in which Catherine played an important part.

At the age of three, Catherine was betrothed to Prince Arthur, heir to the English throne, and they married in 1501, but Arthur died five months later. Catherine subsequently married Arthur's younger brother, the recently-succeeded Henry VIII, in 1509. By 1525 Henry was infatuated with his mistress Anne Boleyn and dissatisfied that his marriage to Catherine had produced no surviving sons, leaving their daughter, the future Mary I of England, as heiress presumptive at a time when there was no established precedent for a woman on the throne. He sought to have their marriage annulled, setting in motion a chain of events that led to England's break with the Roman Catholic Church. When Pope Clement VII refused to annul the marriage, Henry defied him by assuming supremacy over religious matters. In 1533 their marriage was declared invalid and Henry married Anne on the judgement of clergy in England, without reference to the Pope. Catherine refused to accept Henry as Supreme Head of the Church of England and considered herself the King's rightful wife and Queen until her death. Now acknowledged by Henry only as Dowager Princess of Wales, she lived out the remainder of her life at Kimbolton Castle, and died there on 7 January 1536.
