Title: Wives of Henry VIII
Content:  Catherine of Aragon (16 December 1485 – 7 January 1536; Catalina de Aragón) was Henry's first wife. In modern sources, her name is most commonly spelled Catherine, although she spelled and signed her name with a "K," which was an accepted spelling in England at the time. After the death in 1502 of Arthur, her first husband and Henry's brother, a papal dispensation was obtained to enable her to marry Henry, though the marriage did not occur until he came to the throne in 1509. Catherine became pregnant in 1510, but the girl was stillborn. She became pregnant again in 1511 and gave birth to Henry, Duke of Cornwall, who died almost two months later. She gave birth to 
Title: English and British royal mistress
Content:  By contrast, his son Henry VIII took multiple mistresses in addition to his six wives. The first was supposed to be a Frenchwoman named Jane Popincourt, whom he met in 1514, although their relationship is not certain. She had taught languages to Henry's sisters Margaret and Mary. Little is known of her, though she is said to have been a woman of very loose habits. His next mistress, Elizabeth Blount, was seventeen or eighteen when she came to his attention in 1518. The affair was ill-concealed, and Katherine of Aragon grew jealous and attempted to separate them, without success. Early in 1519, Elizabeth gave birth to a 
Title: Henry IV of France's wives and mistresses
Content:   Henry IV of France's wives and mistresses played a significant role in the politics of his reign. Both Henry (1553–1610) and his first wife Margaret of Valois, whom he married in 1572, were repeatedly unfaithful to each other, and the collapse of their marriage led to their estrangement and living apart. Although Henry fathered children with a series of mistresses, his lack of a legitimate heir became a cause of concern, and his marriage was not annulled until 1599. In 1600, at the age of forty-six, he married his second wife, Marie de' Medici, who bore him six children, including the future Louis XIII. Henry was unfaithful to his second wife as well and insisted 
Title: Henry, Duke of Villena
Content:  In November 1418, Henry married his first cousin, Infanta Catherine of Castile, the sister of King John II of Castile. The marriage was a part of an agreement by which Henry's older brother Alfonso V married Catherine's older sister Maria and by which Henry's sister Maria married Catherine's brother John II. Marriage to the King's sister increased Henry's power even more, to the point that the King began to consider him a threat and started seeking support in Álvaro de Luna.

They didn't even know he'd left them."The six women who were married to Henry VIII, in chronological order: Henry's first marriage lasted nearly 24 years, while the following five lasted less than 10 years combined. A mnemonic device to remember the names of Henry's consorts is "Arrogant Boys Seem Clever, Howard Particularly"; a mnemonic for their fates is "Divorced, beheaded, died; divorced, beheaded, survived". Though technically, the first rhyme should be "Annulled, annulled, died; annulled, beheaded, survived" as his marriage to Anne Boleyn was annulled before her beheading, as well as Catherine of Aragon and

Content:  Boleyn, and Jane Seymour each gave him one child who survived infancy: two daughters and one son. All three of these children eventually ascended to the throne as King Edward VI, Queen Mary I, and Queen Elizabeth I. Catherine Howard and Anne Boleyn were first cousins and were both beheaded. Jane Seymour was second cousin to both Anne Boleyn and Catherine Howard. Several of Henry's wives worked in service to another wife, typically as a lady-in-waiting: Anne Boleyn served Catherine of Aragon, Jane Seymour served both Catherine of Aragon and Anne Boleyn, and Catherine Howard served Anne of Cleves.
Title: Wives of Henry VIII
Content:  In common parlance, the wives of Henry VIII were the six queens consort wedded to Henry between 1509 and his death in 1547. In legal terms, King Henry VIII of England had only three wives, because three of his marriages were annulled by the Church of England. However, he was never granted an annulment by the Pope, as he desired, for Catherine of Aragon, his first wife. Annulments declare that a true marriage never took place, unlike a divorce, in which a married couple end their union. Along with his six wives, Henry took several mistresses.
Title: Henry VII of England
Content: Arthur (19 September 1486 – 2 April 1502), Prince of Wales, heir apparent from birth to death ; Margaret (28 November 1489 – 18 October 1541), Queen of Scotland as the wife of James IV and regent for their son James V ; Henry VIII (28 June 1491 – 28 January 1547), Henry VII's successor ; Elizabeth (2 July 1492 – 14 September 1495) ; Mary (18 March 1496 – 25 June 1533), Queen of France as the wife of Louis XII ; Edmund (21 February 1499 – 19 June 1500), styled Duke of Somerset but never formally created a peer ; Katherine (2 February 1503 – 10 February 1503) Henry VII and Elizabeth had seven children: Sir Roland de Velville (or Veleville) was knighted in 1497 and was Constable of Beaumaris Castle. He is sometimes presented as the clear "illegitimate issue" of Henry VII of England by "a Breton lady whose name is not known". The possibility this was Henry's illegitimate son is baseless.
Title: Henry V of England
Content:  In 1420 Henry V married Catherine of Valois, daughter of Charles VI of France and younger sister of the widow of Richard II, Isabella of Valois (who died several years after her husband). Her dowry, upon the agreement between the two kingdoms, was 600,000 crowns. Together the couple had one child, Henry. Upon Henry V's death, the infant prince became King Henry VI of England.
Title: Henry IV of France
Content:  On 18 August 1572, Henry married his second cousin Margaret of Valois; their childless marriage was annulled in 1599. His subsequent marriage to Marie de' Medici on 17 December 1600 produced six children:
