For the son of Prince Albert, see Prince Joachim Albert of Prussia.

Prince Joachim Franz Humbert of Prussia (17 December 1890 – 18 July 1920) was the youngest son of Wilhelm II, German Emperor, by his first wife, Augusta Victoria of Schleswig-Holstein.

Candidate for thrones[edit]

During the Easter Rising in Dublin, Ireland in 1916 some republican leaders contemplated giving the throne of an independent Ireland to Prince Joachim.[1][2]

After Georgia's declaration of independence following the Russian Revolution of 1917, Joachim was briefly considered by the German representative Friedrich Werner von der Schulenburg and Georgian royalists as a candidate to the Georgian throne.[3]


Prince Joachim married Princess Marie-Auguste of Anhalt (10 June 1898 – 22 May 1983), the daughter of Eduard, Duke of Anhalt and his wife Princess Luise of Saxe-Altenburg (daughter of Prince Moritz of Saxe-Altenburg), on 11 March 1916.[4] The couple had one son, the Prince Karl Franz Josef Wilhelm Friedrich Eduard Paul (Potsdam, 15 December 1916 – Arica, Chile 22 Jan 1975).

Later life[edit]

After his father's abdication, Joachim was unable to accept his new status as a commoner and fell into a deep depression, finally committing suicide by gunshot on 18 July 1920 in Potsdam. One source reports that he had been in financial straits and suffered from "great mental depression".[5] His own brother Prince Eitel Friedrich of Prussia commented that he suffered from "a fit of excessive dementia".[5] Before his death, the couple had recently divorced. The direct causes are not really known to the public, only that there had been no previous report of marital troubles before the divorce was announced.[6] Regardless of the reasons, this event may have also contributed to his depression.

Children and grandchildren[edit]

The only issue of the marriage of Prince Joachim and Princess Marie-Auguste was their son, Prince Karl Franz Josef Wilhelm Friedrich Eduard of Prussia (15 December 1916 Potsdam, Germany – 22 January 1975 in Chile).

Prince Karl married first, on 5 October 1940, Princess Henriette Hermine Wanda Ida Luise Schönaich-Carolath (25 November 1918 – 16 March 1972). They divorced 5 September 1946. They were the parents of three children:

Prince Karl married secondly, morganatically, on 9 November 1946, Luise Dora Hartmann (5 September 1909 Hamburg, Germany – 23 April 1961 Hamburg, Germany). The childless couple divorced in 1959.

Prince Karl married lastly, on 20 July 1959 in Lima, Peru, Doña Eva Maria Herrera y Valdeavellano (10 June 1922 Lima, Peru – 6 March 1987 Lima, Peru). They were married until Prince Karl's death and had two daughters;

  • Alexandra Maria Augusta Juana Consuelo Prinzessin von Preussen (born 29 April 1960 Lima, Peru)
  • Désirée Anastasia Maria Benedicta Prinzessin von Preussen (born 13 July 1961 Lima, Peru).
