March 15, 1721 – Death of Louise of Mecklenburg-Güstrow, Queen of Denmark and Norway, first wife of King Frederick IV of Denmark and Norway, at Charlottenborg Palace in Copenhagen, Denmark; buried at Roskilde Cathedral in Roskilde, Denmark
Louise grew up at her father’s modest court at Güstrow Castle. Her parents were adherents to Pietism, a movement in the Lutheran Church in the 17th century that stressed personal piety over religious formality and orthodoxy. In 1695, Louise married the future Frederik IV, King of Denmark and Norway. Louise and Frederik had four sons and one daughter. Sadly, three sons died in infancy. Louise found it difficult to endure her husband’s infidelities and even worse, his two bigamous marriages. At times, Louise reproached her husband, often leading to embarrassing situations at the court. It is suspected that Louise’s deep religiousness was also an escape from her disappointing marriage. Louise took part in the official court life and fulfilled her ceremonial duties. Otherwise, she led a withdrawn and quiet life. Queen Louise died on March 15, 1721, aged 53, at Charlottenborg Palace in Copenhagen, Denmark.

In 1681, Elisabeth Eleonore married Bernhard I, Duke of Saxe-Meiningen, who had been widowed the previous year. Elisabeth Eleonore and Bernhard had five children. The Elisabethenburg Palace in Meiningen was completed in 1692 and named for Elisabeth Eleonore who lived there with her husband, and their children for the duration of Bernhard’s reign. Following her husband’s death in 1706, Elisabeth Eleonore was drawn into the family battles over who would reign over the duchy. The in-fighting within the family took its toll on Elisabeth Eleonore, causing her to retire from public life. She died on March 15, 1729, at the age of 70.

March 15, 1779 – Birth of William Lamb, 2nd Viscount Melbourne (Lord Melbourne), Queen Victoria’s first Prime Minister, in London, England
In June 1837, King William IV died and he was succeeded by his 18-year-old niece Queen Victoria. Victoria never knew her father, Prince Edward, Duke of Kent, because he died when she was eight months old. Melbourne was her first Prime Minister. In Queen Victoria, Melbourne had the child, the companion, and the affection he craved. In Melbourne, Queen Victoria had the father figure she never had. Their close relationship was founded in Melbourne’s responsibility for tutoring the young queen about world politics and instructing her in her role, but the relationship was much deeper. Queen Victoria came to regard Lord Melbourne as a mentor and personal friend and he was given a private apartment at Windsor Castle. He resigned as Prime Minister in August 1841 after a series of parliamentary defeats. Melbourne and Queen Victoria said a private goodbye on the terrace at Windsor Castle. Victoria cried and Melbourne told her, “For four years I have seen you daily and liked it better each day.”

That same year he married his first cousin Princess Caroline Matilda of Wales, daughter of Christian’s deceased maternal uncle Frederick, Prince of Wales.

In 1878, Arthur met Princess Louise Margaret of Prussia on a visit to his eldest sister Victoria, German Crown Princess and Crown Princess of Prussia. Louise Margaret was friendly with the Crown Princess and her eldest daughter Charlotte. Queen Victoria considered Louise Margaret to be a less than satisfactory possible bride for her son. She was plain-looking and had bad teeth. Her parents were unpleasant, had an unhappy marriage, and lived apart. Queen Victoria wanted to avoid associating her family with a possible scandal. However, because Arthur was so happy at the prospect of marrying Louise Margaret, Queen Victoria remained open-minded. When Queen Victoria met Louise Margaret, she became more positive and the engagement was announced.

March 13, 1881 – Assassination of Alexander II, Emperor of All Russia when a bomb is thrown at him near the Winter Palace in St. Petersburg, Russia; buried at the Peter and Paul Cathedral in St. Petersburg
Of the twenty Romanov monarchs, five died violent deaths (Ivan VI, Peter III, Paul I, Alexander II, and Nicholas II). Alexander II was riding in a bomb-proof carriage, a gift from Emperor Napoleon III of France. As the carriage turned onto the Catherine Canal Embankment, a bomb was thrown. The carriage was damaged and several onlookers were wounded, but the emperor was unharmed. Next, Alexander II made a mistake that cost him his life. Unaware that another conspirator was leaning against a railing about six feet away, he left the carriage to inspect the damage and check on the wounded people, and a bomb was thrown directly between the emperor’s legs. The noise from the bomb was deafening, smoke filled the air, wounded people were screaming, and the snow was drenched with blood. When the smoke cleared, Alexander II lay mortally wounded, his legs crushed and torn from the blast of the bomb. Alexander asked to be taken to the Winter Palace so he could die there. Just the day before he died, Alexander II had completed plans to create an elected parliament and he intended to release these plans within a few days. Perhaps if Alexander II had lived Russia would have become a constitutional monarchy and not been led down the path the country ultimately took. Alexander II’s son and successor Alexander III was very conservative and reversed some liberal reforms of his father. One of the first things he did as emperor was to tear up his father’s plans for an elected parliament and cancel the order his father had signed the day he died.

March 13, 1981 – Birth of Grand Duke George Mikhailovich of Russia in Madrid, Spain, the only child of Grand Duchess Maria Vladimirovna of Russia, a disputed pretender to Headship of the Russian Imperial Family and the throne of Russia since 1992
Grand Duke George Mikhailovich of Russia, also known as Prince George of Prussia through his father Prince Franz Wilhelm of Prussia, a great-grandson of Wilhelm II, German Emperor and King of Prussia), is the heir to his mother Grand Duchess Maria Vladimirovna of Russia, a disputed pretender to the Headship of the Russian Imperial Family and the throne of Russia since 1992. The Headship of the Russian Imperial Family and succession to the former Russian throne has been in dispute, mainly due to disagreements over whether marriages in the Romanov family were equal marriages – a marriage between a Romanov dynast and a member of a royal or sovereign house. In 2021, George married Rebecca Virginia Bettarini, Director of the Russian Imperial Foundation in a civil ceremony in Moscow, Russia, on September 24, 2021, followed by a religious wedding on October 1, 2021, at Saint Isaac’s Cathedral in St. Petersburg, Russia.

March 12, 1972 – Death of Feodora of Saxe-Meiningen, Grand Duchess of Saxe-Weimar-Eisenach, second wife of Wilhelm Ernst, Grand Duke of Saxe-Weimar-Eisenach, in Freiburg im Breisgau, Germany; buried in Bad Krozingen, Germany
Feodora was the great-granddaughter of Princess Feodora of Leiningen, the half-sister of Queen Victoria of the United Kingdom. In 1910, she married Grand Duke Wilhelm Ernst of Saxe-Weimar-Eisenach, and they had four children. Feodora struggled to cope with the strict etiquette and protocol of the Weimar court. She was active in charitable organizations that helped the poor. After World War I, her husband abdicated in November 1918 and the family went into exile in Heinrichau, Silesia (now Henryków, Poland), where her husband died several years later. When the area fell under Soviet occupation in World War II, the family was again forced to flee, losing their estates and many of their assets. As a means of negotiating with the authorities, Feodora agreed to sign over the Goethe and Schiller Archive, on the condition that it would be converted into a private foundation, and the family’s assets would be returned. Despite the written agreement, the government did not return many of the family’s assets, and the dispute continues today. Feodora settled in Freiburg im Breisgau, Germany, where she died on March 12, 1972, at the age of 82.
