In 1350, with encouragement from his mother, Eleanor’s younger son Edward began a civil war against his brother Reinald III for control of the Duchy of Guelders. When Eleanor attempted to reconcile with her son Reinald, he rejected her reconciliation attempts and confiscated her property.

King Henry VII was the son of Edmund Tudor, 1st Earl of Richmond, who died three months before his son’s birth, leaving a 13-year-old pregnant widow, Lady Margaret Beaufort. Henry’s father, Edmund Tudor, was the eldest child of Owen Tudor and Catherine of Valois, widow of King Henry V of England. His mother, Lady Margaret Beaufort, was the only child of John Beaufort, 1st Duke of Somerset and Margaret Beauchamp of Bletso. Lady Margaret was a descendant of King Edward III of England through her father. At the time of Henry’s birth, the Wars of the Roses, the fight for the English throne between the House of Lancaster and the House of York, was two years old. His mother was a descendant of the House of Lancaster. In 1470, after the Lancastrian King Henry VI was murdered in the Tower of London, Henry’s uncle, Jasper Tudor, left England for France and took his nephew Henry with him to keep him safe. In 1485,  Henry Tudor sailed to Wales with a small French and Scottish force. He then marched towards England accompanied by his uncle Jasper Tudor and John de Vere, 13th Earl of Oxford. On August 22, 1485, at the Battle of Bosworth Field, the last significant battle of the Wars of the Roses, the last king of the House of York and the Plantagenet dynasty, King Richard III of England, lost his life and his crown. The battle was a decisive victory for the House of Lancaster, whose leader, 28-year-old Henry Tudor, Earl of Richmond, became the first monarch of the House of Tudor. In 1486, King Henry VII married Elizabeth of York, King Edward IV’s eldest child, uniting the House of York and the House of Lancaster. Henry and Elizabeth had seven children, including King Henry VIII of England. Through their daughter Margaret Tudor, they are the ancestors of the British royal family and many other European royal families.

The couple married in 1699, and had three children, but their only son died from hydrocephalus before his first birthday. Joseph did not stop his affairs, and the affairs combined with the death of his only son took a toll on his marriage. In 1705,  Joseph succeeded his father in the Habsburg hereditary lands and was elected Holy Roman Emperor. Six years later, Joseph died from smallpox. In 1722, after both her daughters had married, Wilhelmine Amalie retired to the convent she had founded for the Salesian nuns, the Monastery of the Visitation of Mary in Vienna, where she died eleven days before her sixty-ninth birthday.

Upon becoming king, Frederik wished to marry Louise but the government was not in favor of the marriage. In 1849, King Frederik VII signed a new constitution, changing the monarchy from an absolute monarchy to a constitutional monarchy. The signing of the new constitution made Frederik so popular that the government granted him permission to morganatically marry Louise Rasmussen. Louise was not queen consort and was officially styled as Countess Danner. The marriage appears to have been a happy one but had much opposition and Louise was treated poorly in social circles. Frederik and Louise did not have any children. Frederik died in 1863 and Louise survived him by eleven years, dying in Genoa, Italy on March 6, 1874, at the age of 58. While King Frederik VII was buried at Roskilde Cathedral, the traditional burial place of the Danish Royal Family, Louise was not accorded a resting place near her husband.

Another child, a daughter was born in 1801. The two children, deemed illegitimate, used the last name D’Este as both their parents were descendants of the House of Este. After the death of Augusta in 1830, Augustus married again in contravention of the Royal Marriages Act, to a widow, Lady Cecilia Buggin. Because marriage was not considered legal, Cecilia could not take the style and title Her Royal Highness The Duchess of Sussex, so instead, she assumed the surname Underwood, her mother’s maiden name, and was known as Lady Cecilia Underwood. The couple lived at Augustus’ apartments in Kensington Palace. Despite all of this, Augustus was respected by his niece Queen Victoria. He was given the honor of giving her away at her wedding. As a token of her gratitude, Queen Victoria created Augustus’ wife Cecilia Duchess of Inverness in her own right in 1840. On April 21, 1843, Augustus died from erysipelas at the age of 70. Because Augustus feared that his second morganatic wife would not be allowed to be buried in the Royal Vault at St. George’s Chapel, Windsor, he left instructions that he be buried at Kensal Green Cemetery in Kensal Green, London, England, where his wife was later buried.

Xenia settled in England where she was granted management letters for the properties of her brother Nicholas in England which gave her an income of 500 pounds sterling per year. By 1925, Xenia’s financial situation was desperate and her first cousin King George V allowed her the use of Frogmore Cottage, a grace and favor house, in Windsor Great Park. In March 1937, King George VI, Xenia’s first cousin once removed, granted her the use of Wilderness House, a grace and favor house, on the grounds of Hampton Court Palace where she died on April 20, 1960, at the age of 85.

When widower King Christian IV became attracted to 18-year-old Kirsten, her astute mother did not want her daughter to become Christian’s mistress, and instead negotiated a morganatic marriage between Christian and her daughter due to Kirsten’s status as a noble.

April 19, 1956 – Wedding of Prince Rainier III of Monaco and Grace Kelly at St. Nicholas Cathedral in Monaco
Before her marriage, Grace Kelly was a well-known film actress who won the Academy Award for Best Actress for The Country Girl, which also starred Bing Crosby and William Holden. Since much of Grace and Rainier’s lives were in the public eye, a private courtship was difficult, especially considering the distance between the United States and Monaco. After meeting the Prince in Monaco during the Cannes Film Festival in May 1955, Grace corresponded with Rainier until he made a trip to the United States in December of that year. He asked Grace to marry him over the Christmas holiday, and on January 5, 1956, their engagement was announced in a press conference held at her family’s home in Philadelphia.

April 19, 1968 – Birth of King Mswati III of Eswatini at Raleigh Fitkin Memorial Hospital in Manzini, then in Swaziland (name changed to Eswatini in 2018)
Born: Prince Makhosetive Dlamini
King Mswati is one of many sons fathered by King Sobhuza II, who married 70 wives and had 210 children between 1920 and 1970.  King Sobhuza II died in 1982, at the age of 83, having reigned for 82 years. Kings cannot appoint their successors, nor is there a line of succession. A traditional council called the Liqoqo decides which of the wives shall be “Great Wife” and “Indlovukati” (She-Elephant / Queen Mother) after the death of a king. The “Great Wife” must be of good character and cannot be one of the first two wives (known as ritual wives) chosen for the king by the national councilors. The son of this “Great Wife” will automatically become the next king. 14-year-old Mswati was selected to be the next king.
