# Frederick William III, Landgrave of Hesse

Frederick William (III), Landgrave of Hesse-Kassel (German: Friedrich Wilhelm Nikolaus Karl, 15 October 1854 – 14 October 1888) was (titular) Elector of Hesse-Kassel.

## Early life

He was the eldest son of Frederick William George Adolph of Hesse-Kassel-Rumpenheim and his second wife Princess Anna of Prussia. His father's first wife was Alexandra Nikolaevna of Russia, daughter of Emperor Nicholas I of Russia but she died in childbirth delivering a son who also died. From his parents marriage, his siblings were Princess Elisabeth (who married Leopold, Hereditary Prince of Anhalt), Prince Alexander Frederick (who married Baroness Gisela Stockhorner von Starheim), Prince Frederick Charles of Hesse (who married Princess Margaret of Prussia), Princess Marie-Polyxene (who died young), and Princess Sybille (who married Friedrich Alexander Henry Robert Carl Albert, Baron von Vincke).
His father was the only son of Wilhelm I, Landgrave of Hesse-Kassel-Rumpenheim and Princess Louise Charlotte of Denmark. His maternal grandparents were Prince Charles of Prussia and Princess Marie of Saxe-Weimar-Eisenach.
Like his father he was raised in Denmark.

## Landgrave of Hesse

His father died in 1884, and he inherited the title of Landgrave which provided an allowance of £25,000 a year from the German government in addition to his extensive estates in Holstein and Hesse Castle.

## Death

Frederick William III died on 14 October 1888 during a trip aboard the steamship Volga from Batavia to Singapore. He was traveling with Barons von Hugo, von Trott and von der Schulenburg. According to his obituary he died:
   "under circumstances that leave no room for doubt whatever as to the death of his Royal Highness. His Royal Highness, who had been a long time traveling in the tropics, had in the course of his wanderings reached Java. The only possible conclusion which could be come to was that, overcome by some sudden mental disturbance, to which his previous illness may have made him susceptible, his Royal Highness had, quite unconscious of what he was doing, gone through the port of his cabin, and had dropped into the sea. He could not merely have fallen through, as the window was so narrow that a person could only pass through by dint of some exertion. The idea of premeditated suicide is entirely without foundation."
As was not married and had no children, he was succeeded by his brother, Alexander Frederick, who was an accomplished musician despite being nearly blind. Upon his brother and heir's morganatic marriage in 1925, he abdicated in favor of their younger brother, Prince Frederick Charles of Hesse, who had been elected King of Finland in 1918 but renounced the throne two months later. Prince Frederick married Princess Margaret of Prussia, youngest sister of Kaiser Wilhelm II and a granddaughter of Queen Victoria of Great Britain.
