Prince Hubertus of Prussia (Hubertus Karl Wilhelm; 30 September 1909 – 8 April 1950) was the third son of Crown Prince Wilhelm of Germany and Duchess Cecilie of Mecklenburg-Schwerin.
He joined the army in 1934 (infantry regiment 8 in Frankfurt/Oder) and participated in the Invasion of Poland in 1939. One year later he was dismissed from the army by Hitler's Prinzenerlaß, following the death of his elder brother Prince Wilhelm of Prussia, who was wounded in France on 23rd May 1940 and died in a Field hospital in Belgium three days later.
Marriage and issue
On 29 December 1941, he married Baroness Maria Anna von Humboldt-Dachroeden (9 July 1916 – 24 September 2003) in Oels, Schlesien. They divorced a little over a year later in early 1943 (the same year she would later give birth to Hubertus' cousin, Ernest Augustus', illegitimate son), and on 5 June of that year, he married again to Princess Magdalena Reuss of Köstritz (20 August 1920 – 10 October 2009). They had two daughters:
- Princess Anastasia Victoria Cecilia Hermine of Prussia (born 14 February 1944); married Alois-Konstantin, 9th Prince of Löwenstein-Wertheim-Rosenberg and had issue.
