Jurij Slatkonja was a choirmaster for which State of the Holy Roman Empire?
Duchy of Carniola The Duchy of Carniola (Slovene: "Vojvodina Kranjska" , German: "Herzogtum Krain" ) was a State of the Holy Roman Empire, established under Habsburg rule on the territory of the former East Frankish March of Carniola in 1364. A hereditary land of the Habsburg Monarchy, it became a constituent land of the Austrian Empire in 1804 and part of the Kingdom of Illyria until 1849. A separate crown land from 1849, it was incorporated into the Cisleithanian territories of Austria-Hungary from 1867 until the state's dissolution in 1918. Its capital was Ljubljana.
Free Imperial City of Nuremberg The Imperial City of Nuremberg (German: "Reichsstadt Nürnberg" ) was a free imperial city — independent city-state — within the Holy Roman Empire. After Nuremberg gained piecemeal independence from the Burgraviate of Nuremberg in the High Middle Ages and considerable territory from Bavaria in the Landshut War of Succession, it grew to become one of the largest and most important Imperial cities, the 'unofficial capital' of the Empire, particularly because Imperial Diets ("Reichstage ") and courts met at Nuremberg Castle. The Diets of Nuremberg were an important part of the administrative structure of the Empire. The Golden Bull of 1356, issued by Emperor Charles IV (reigned 1346–78), named Nuremberg as the city where newly elected kings of Germany must hold their first Imperial Diet, making Nuremberg one of the three highest cities of the Empire.
