February 23, 1447 – Death of Humphrey, Duke of Gloucester, son of King Henry IV of England, at Bury St. Edmunds, Suffolk, England; buried at the Abbey Church of St. Albans in Hertfordshire, England
Humphrey received an excellent education and it is thought he was educated at Balliol College, Oxford. He had a great love of learning, was a collector of books and manuscripts, and commissioned translations of classical works from Greek into Latin. When Humphrey died, he donated his collection of 281 manuscripts to the University of Oxford. The university built Duke Humfrey’s Library as a second story to the Divinity School to house his collection in 1450-80. Duke Humfrey’s Library still exists and it is the oldest reading room in the Bodleian Library at the University of Oxford. During the early reign of his nephew King Henry VI,  Humphrey had become the heir presumptive to the throne after the death of his older brother John, Duke of Bedford and it was feared that if Henry VI left England, Humphrey could exercise his claim to be regent. Humphrey was hostile to the French while the English powers that be wanted peace. Humphrey was arrested and it appeared there would be a trial that would result in Humphrey’s disgrace or even a worse fate. However, there was no trial as five days later, Humphrey died. There is some suspicion that some foul play was involved, but most likely Humphrey had a stroke because he was in a coma for three days before he died.

February 23, 1779 – Birth of Prince Octavius of Great Britain, son of King George III of the United Kingdom, at the Queen’s House, now Buckingham Palace, in London, England
Smallpox was a leading cause of death in the 18th century. By having their children inoculated against smallpox, King George III and Queen Charlotte were trying to protect them and starting down the long road that would eventually lead to the eradication of this terrible disease.  Before Edward Jenner developed the smallpox vaccine that contained the cowpox virus, variolation, first seen in China in the fifteenth century, was another way to protect against smallpox. Live smallpox virus in the liquid taken from a smallpox blister in a mild case of the disease was put into a cut of a healthy person who developed a very mild case of smallpox.  About 3% of those inoculated developed a severe case of smallpox and died but that was preferable to catching smallpox with its mortality rate of 20–40% and scarred survivors. Sadly, four-year-old Octavius was one of those who died after inoculation.

Naruhito, the current Emperor of Japan, is the elder of the two sons and the eldest of the three children of former Emperor Akihito and Michiko Shōda. In 1993, he married Masako Owada and the couple had one daughter. On May 1, 2019, Naruhito ascended to the Chrysanthemum Throne as Emperor of Japan upon the abdication of his father Emperor Akihito.

Currently, there are only three people in the line of succession: Crown Prince Akishino (born in 1965, brother of Emperor Naruhito), Prince Hisahito, (born in 2005, son of Crown Prince Akishino), and Prince Hitachi (born in 1935, uncle of Emperor Naruhito). Probably, there will not be another person in the line of succession until Prince Hisahito marries and has a son.

David II, King of Scots; Credit – Wikipedia

February 22, 1371 – Death of David II, King of Scots at Edinburgh Castle in Edinburgh, Scotland; buried at Holyrood Abbey in Edinburgh, now in ruins
The second and last monarch of the House of Bruce, David II, King of Scots is one of the longest-reigning monarchs of Scotland, having reigned for 41 years, 260 days. He was the only surviving son of Robert I, King of Scots (also known as Robert the Bruce) and his second wife Elizabeth de Brugh. In 1328, four-year-old David married seven-year-old Joan of the Tower, the youngest daughter of King Edward II of England and Isabella of France. David’s mother had died in 1327 and upon the death of his father on June 7, 1329, five-year-old David succeeded to the Scottish throne. Joan died in 1362, at the age of 41, without giving her husband an heir. David married his mistress Margaret Drummond in 1364. He divorced her in 1370 on the grounds of infertility. However, Margaret successfully petitioned Pope Urban V to reverse the divorce because it seemed likely that David was infertile as his 34-year marriage to his first wife produced no issue. In the later years of his reign, David continued to pursue peace with England and worked to make Scotland a stronger kingdom with a more prosperous economy. David, aged 46, died unexpectedly in 1371. As both his marriages were childless, David was succeeded by his nephew, the son of his half-sister Marjorie, who became Robert II, King of Scots, the first monarch of the House of Stewart.

In June 2013, Delphine filed a lawsuit to prove, through DNA testing, that she was King Albert II’s biological child. After a long legal process, in January 2020, the former King Albert II finally acknowledged that he was Delphine’s biological father, as proven by DNA testing. On October 1, 2020, the Belgian Court of Appeal ruled that Delphine and her children are entitled to the style and title of HRH Prince/Princess of Belgium, and can use the former King’s surname of Saxe-Coburg. In addition, she is legally entitled to inherit one-quarter of the former King’s estate – a share equal to that of his three legitimate children. She is still considered illegitimate (born out of wedlock) and as such, Delphine and her descendants are not in the line of succession to the Belgian throne.

February 20, 1618 – Death of Filips Willem, Prince of Orange at the Palace of Nassau in Brussels; buried at the Catholic parish church of Saint Sulpice in Diest, now in Belgium
Filips Willem was the only son of Willem I (the Silent), Prince of Orange, and the first of his four wives Anna van Egmont. In 1568, Willem I, Filips Willem’s father, became the main leader of the Dutch revolt against the Spanish Habsburgs who held the land that we now know as the Netherlands and Belgium. That set off the Eighty Years’ War and resulted in the formal independence of the Dutch Republic in 1581. Angered by Willem I’s revolt, King Philip II of Spain arranged for 13-year-old Filips Willem to be kidnapped and taken to Spain, partly as a hostage, but also to be raised as a Catholic and a loyal subject to Spain. Filips Willem never saw his father again. In 1584, Balthasar Gérard, a subject and supporter of Philip II, assassinated Willem I. Filips Willem became Prince of Orange, however, he was not allowed to return to his homeland because he was not trusted and was considered an agent of Spain. In 1596, 28 years after he was kidnapped, Filips Willem returned to the Netherlands and lived at the Palace of Nassau in Brussels. At the request of the States-General (the legislature), he did not engage in political affairs. Filips Willem died on February 20, 1618, aged 63, after a botched medical procedure. In his will, he requested to be buried in one of his cities (Breda, Orange, Lons-le-Saunier, or Diest) whichever would be closest to his place of death. He had a Catholic funeral and was buried at the Catholic parish church Saint Sulpice in Diest, now in Belgium.
