When were the revolutions that Joanneum was named after this member of the House of Habsburg-Lorraine?
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.
Electorate of Mainz The Electorate of Mainz (German: "Kurfürstentum Mainz" or "Kurmainz ", Latin: "Electoratus Moguntinus" ), also known in English by its French name, Mayence , was the most prestigious and among the most influential states of the Holy Roman Empire from its creation to the dissolution of the HRE in the early years of the 19th century. In the Roman Catholic hierarchy, the Archbishop-Elector of Mainz was the Primate of Germany ("primas Germaniae "), a purely honorary dignity that was unsuccessfully claimed from time to time by other Archbishops. There were only two other ecclesiastical Prince-electors in the Empire: the Electorate of Cologne and the Electorate of Trier.
