The Franco-Italian army led by Eugène de Beauharnais was defreated by an Austrian army commanded by a member of what house?
Archduke John of Austria Archduke John of Austria (German: "Erzherzog Johann Baptist Joseph Fabian Sebastian von Österreich" ; 20 January 1782 – 11 May 1859), a member of the House of Habsburg-Lorraine, was an Austrian field marshal and Imperial regent ("Reichsverweser") of the short-lived German Empire during the Revolutions of 1848.
Hohenberg family The Ducal House of Hohenberg is an Austrian noble family that descends from Countess Sophie Chotek (1868–1914), who in 1900 married Archduke Francis Ferdinand of Austria-Este (1863–1914), the heir presumptive to the throne of the Austro-Hungarian Empire. As their marriage was a morganatic one, none of their children were in the line of succession to the Austro-Hungarian throne. Still, they represent the senior agnatic line of the House of Habsburg-Lorraine.
