Few historical figures still spark arguments the way Henry VIII does—a king who married six times and had two wives executed still manages to surprise us. By the time he died on 28 January 1547 at Whitehall Palace, he had transformed England’s religion, beheaded two of his queens, and left a succession crisis that would define the Tudor dynasty — and this article looks beyond the familiar stories to ask what actually killed him, whether his health shaped his decisions, and how modern medicine reinterprets his decline.

What was the cause of Henry VIII’s death?
Six centuries after his death, historians and doctors still don’t agree on a single cause. The official record—court accounts and ambassadors’ letters—describe a man who grew massively obese, developed a festering leg ulcer after a 1536 jousting accident, and finally expired at age 55. Modern medical reviews have narrowed the possibilities.
Henry’s body gave out because too many systems failed at once. The real story is not a single disease but a cascade: obesity stressed his heart, the leg ulcer seeded infection, and his kidneys may have shut down. The king who once dominated the jousting field was undone by his own lifestyle and one unlucky fall.
Medical theories: obesity, gout, syphilis
A 2009 medical review in PubMed Central (peer-reviewed medical journal) argued that Henry VIII likely suffered from congestive cardiac failure associated with vascular disease, based on descriptions of his swollen legs near the end of life. The same review notes that he had been a “fit and active young man” before his health deteriorated. An earlier article from SAGE Journals (academic medicine) lists possible causes including obesity, gout, and syphilis, though syphilis remains unproven.
The role of jousting injuries
Henry’s 1536 jousting accident is often called a turning point. According to Historic UK (British history site), the injury caused a chronic leg ulcer that periodically burst open.
That ulcer likely became infected, contributing to the systemic inflammation that may have triggered kidney failure or sepsis.
Contemporary accounts vs modern diagnosis
Court chroniclers recorded a man who could barely walk in his final years, carried up stairs by servants. His “grossly swollen legs” were noted by foreign diplomats. A modern interpretation in PubMed Central (historical-medical analysis) suggests that the swelling points to heart failure, and that his later paranoia and mental decline may have been linked to metabolic disturbances, though the syphilis theory is often invoked but never proven.
Bottom line: Henry VIII likely died from multi-organ failure driven by obesity-related heart disease and a chronic leg infection. Syphilis is a popular explanation but lacks firm evidence.
Why was Henry VIII so famous?
Henry VIII’s fame rests on three pillars: he broke with the Catholic Church to get a male heir, he married six times, and he left a cultural footprint that still draws tourists and TV producers. No other English monarch combined such personal drama with such lasting structural change.
The break with Rome and English Reformation
When Pope Clement VII refused to annul his marriage to Katherine of Aragon, Henry pushed through the Act of Supremacy in 1534, making himself Supreme Head of the Church of England. The PubMed Central (peer-reviewed medical journal) notes that this move gave him control over church revenues and doctrine—and paved the way for the English Reformation.
His six marriages
Two wives were executed (Anne Boleyn and Catherine Howard), one died in childbirth (Jane Seymour), two were divorced (Katherine of Aragon, Anne of Cleves), and one survived him (Catherine Parr). The need for a male heir drove every marriage decision. Only three children survived infancy: Mary, Elizabeth, and Edward—all of whom became monarchs.
Cultural impact and portrayals
From Holbein’s iconic portrait to modern TV series like The Tudors, Henry VIII remains a staple of popular culture. English schoolchildren learn the rhyme “divorced, beheaded, died” to remember the fates of his wives. The Hektoen International (medical humanities journal) describe him as a “terrible Tudor” whose legacy still shapes the Church of England and the British monarchy.
For a comparison with another monarch’s health legacy, see our article on King Charles: Health, Succession & Family Facts.
Bottom line: Henry VIII is famous because he upended Europe’s most powerful institution for a personal goal, married six times in the process, and left a dynasty that defined modern Britain.
Why did Henry VIII kill his wives?
The short answer: two wives were executed on charges of adultery and treason, but the motive was always dynastic. Henry needed a male heir, and when he believed his wives were unfaithful or could not give him a son, he removed them.
Anne Boleyn: adultery charges
Anne Boleyn was executed on 19 May 1536 after being convicted of adultery, incest, and high treason. The charges are widely considered fabricated. Cambridge University Press (academic historical journal) notes that she had multiple pregnancies that did not produce a surviving son—a fatal failure in Henry’s eyes.
Catherine Howard: adultery
Henry’s fifth wife was executed in 1542 for adultery—she had engaged in a pre-marital relationship with Thomas Culpeper. By this time Henry was in declining health and increasingly paranoid. The execution served to protect his reputation and the legitimacy of any future heirs.
The need for a male heir
Henry’s obsession with a male heir explains the pattern. Katherine of Aragon gave him a daughter, Mary, but subsequent pregnancies ended in miscarriage or stillbirth. NBC News (public health summary) documents that both Katherine and Anne Boleyn suffered repeated pregnancy losses, leading Henry to conclude that his wives were cursed or disloyal.
Bottom line: Henry killed his wives not out of cruelty alone, but out of a desperate, single-minded drive to secure the Tudor line. When he believed a wife could not give him a son, he had her removed.
Who was the rudest wife of Henry VIII?
By most accounts, Henry himself was the rude one. But among the six, Anne of Cleves and Katherine of Aragon stood out for their resistance.
Anne of Cleves: ‘Flanders Mare’
Henry famously called Anne of Cleves the “Flanders Mare” after seeing her in person—a crushing insult for a woman he had agreed to marry based on a portrait. The marriage was annulled after six months, but Anne got a generous settlement and outlived Henry. The PubMed Central (historical-medical analysis) describes her as one of the few wives who successfully negotiated a peaceful exit.
Catherine Parr: the nurse
Catherine Parr, his sixth wife, survived by managing Henry’s temper. She was educated, Protestant-leaning, and acted as regent when he went to war. She is often called his “nurse” because she cared for him in his final years. She avoided execution by deflecting theological arguments.
Katherine of Aragon: strong-willed
Henry’s first wife refused to accept the annulment, arguing that her marriage was valid. She spent her final years in isolation, but she never backed down. Her defiance helped trigger the break with Rome. Cambridge University Press (academic historical journal) notes her repeated pregnancy losses, which ultimately sealed her fate.
Bottom line: The “rudest” wife title belongs to the women who stood up to Henry—Katherine of Aragon through resistance and Anne of Cleves through quiet survival. The truly rude one was always the king.
Was Henry VIII a nasty man?
Historians have long debated whether Henry was evil or simply a product of his time. The evidence points to a man capable of great cruelty, especially in his later years when illness may have worsened his temper.
Executions: Thomas More, John Fisher
Henry ordered the execution of Sir Thomas More, his former friend and Lord Chancellor, because More refused to accept the Act of Supremacy. Bishop John Fisher suffered the same fate. Both were canonised as Catholic martyrs. The number of executions during Henry’s reign is disputed—some sources claim 72,000, but Hektoen International (medical humanities journal) treats that figure as unreliable.
Dissolution of monasteries
Between 1536 and 1541, Henry dissolved over 800 monasteries, seizing their wealth and destroying religious art. The policy caused widespread social upheaval, displacing monks and nuns and leaving rural communities without charity. SAGE Journals (academic medicine) frames the dissolution as a central part of Henry’s “terrible Tudor” reputation.
Historical reputation vs modern view
Modern historians like David Starkey describe Henry as “a man of great abilities but terrible passions.” The Historic UK (British history site) officially asks “Henry VIII, Terrible Tudor?” on their website, acknowledging that his legacy is mixed. The evidence suggests he was both visionary and brutal—a king who could write poetry and order an execution in the same week.
Bottom line: Henry VIII was indeed nasty by modern standards, but his actions must be weighed against the political realities of absolute monarchy. The dissolution of the monasteries alone affected hundreds of thousands of lives.
What disease did Anne Boleyn have?
Anne Boleyn’s health remains a medical mystery. Contemporary accounts note a strange growth on her neck and what may have been a thyroid condition. Modern speculation ranges from breast cancer to syphilis, but no definitive diagnosis exists.
Speculation: syphilis, breast cancer
Some historians have suggested that Anne had syphilis, which would explain the stillbirths and later health problems. However, PubMed Central (historical-medical analysis) notes that syphilis in Henry’s wives is unproven and that the king himself may have had it—but again, no firm evidence. Another theory is breast cancer, which could explain her neck swelling if the cancer had metastasised to lymph nodes.
Historical symptoms
Anne’s symptoms recorded by court doctors include a “strange growth” on her neck, intermittent fevers, and multiple miscarriages. Her final pregnancy ended in a late miscarriage in 1536, the event that sealed her fate. Cambridge University Press (academic historical journal) records that her reproductive history mirrors Katherine of Aragon’s—multiple pregnancies ending in loss.
Lack of contemporary diagnosis
Sixteenth-century medicine could not identify the cause of her symptoms. No autopsy was performed. The Hektoen International (medical humanities journal) has even proposed that Henry’s own blood type (possibly Kell-positive) could have caused immune reactions in his wives, leading to miscarriages. This remains speculative but intriguing.
Bottom line: Anne Boleyn’s disease is unknown. The most plausible candidates are an undiagnosed autoimmune or metabolic condition, perhaps linked to the same genetic factors that troubled Henry’s other pregnancies.

The legacy of Henry VIII
Henry VIII reshaped England more than any monarch before or after. He broke a thousand-year-old church, executed two wives, and left a succession that produced three very different Tudor monarchs. But his personal tragedy—a desperate, failed search for a healthy son—may have been written in his own genes. For visitors to Hampton Court today, the lesson is not about power but about how one man’s body failed him at the very moment he needed it most.
