Duchy of Holstein The Duchy of Holstein (German: "Herzogtum Holstein" , Danish: "Hertugdømmet Holsten" ) was the northernmost state of the Holy Roman Empire, located in the present German state of Schleswig-Holstein. It was established when King Christian I of Denmark had his County of Holstein-Rendsburg elevated to a duchy by Emperor Frederick III in 1474. Holstein was ruled jointly with the Duchy of Schleswig by members of the Danish House of Oldenburg for its entire existence.
Electorate of Saxony The Electorate of Saxony (German: "" , also "Kursachsen "), sometimes referred to as Upper Saxony, was a State of the Holy Roman Empire established when Emperor Charles IV raised the Ascanian duchy of Saxe-Wittenberg to the status of an Electorate by the Golden Bull of 1356. Upon the extinction of the House of Ascania, it was enfeoffed to the Margraves of Meissen from the Wettin dynasty in 1423, who moved the residence up the Elbe river to Dresden. After the Empire's dissolution in 1806, the Wettin electors raised Saxony to a kingdom.
