Overview
Prince Ernst of Hohenberg (Ernst Alfons Franz Ignaz Joseph Maria Anton von Hohenberg; 27 May 1904 – 5 March 1954) was the second son of Archduke Franz Ferdinand of Austria and his morganatic wife Sophie, Duchess of Hohenberg, who were assassinated at Sarajevo in 1914.
Life
Prince Ernst was born at his parents' estate at Konopiště in Bohemia. Following his parents' assassination, which precipitated World War I, Ernst and his siblings, Sophie and Maximilian, were taken in by their uncle, Prince Jaroslav von Thun und Hohenstein.
In late 1918, their properties in Czechoslovakia, including Konopiště and Chlumec nad Cidlinou, were confiscated. The children moved to Vienna and Schloß Artstetten.
