Joachim Ernst, Duke of Anhalt

Joachim Ernst, Duke of Anhalt (11 January 1901 – 18 February 1947) was the last ruler of the Duchy of Anhalt.

Biography
He was born in Dessau, the son of Duke Eduard of Anhalt (1861–1918) and Princess Louise Charlotte of Saxe-Altenburg (1873–1953), the daughter of Prince Moritz of Saxe-Altenburg.

He succeeded his father as Duke of Anhalt on 13 September 1918. However, due to his age, his uncle Prince Aribert of Anhalt was appointed regent. His brief reign came to an end on 12 November 1918, with his uncle abdicating in his name following the German revolution. The duchy became the Free State of Anhalt and is today part of the state of Saxony-Anhalt.

Thus Joachim Ernst was the last ruler of a constituent state within the German Empire to succeed to the throne, and the only German monarch to be born in the 20th century.

Joachim Ernst joined the ruling Nazi Party in 1939. He died after World War II at the NKVD special camp Nr. 2 near Weimar Germany ( former Buchenwald concentration camp)  as a prisoner of the Soviet Union.

Following his death, the headship of the Ducal House of Anhalt was disputed between his elder son, Prince Friedrich, and brother Prince Eugen.
