Question: Jurij Slatkonja was a choirmaster for which State of the Holy Roman Empire?
Context: Schönborn is a noble and mediatised former sovereign princely family from the former Holy Roman Empire.  Several members of the family have held high offices of the Roman Catholic Church and the Holy Roman Empire over the course of centuries, including as Bishops, Prince-Bishops, Cardinals and Prince-Electors.  In addition to several family members having been elected monarchs of ecclesiastical principalities—the Electorate of Mainz, the Prince-Bishopric of Würzburg, the Prince-Bishopric of Worms, the Prince-Bishopric of Speyer, the Electorate of Trier, and the Prince-Bishopric of Bamberg—the family possessed a fiefdom in Franconia that held imperial immediacy, and was thus a principality of the Holy Roman Empire, the state of Schönborn. 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. The monarchs of Prussia were members of the House of Hohenzollern who were the hereditary rulers of the former German state of Prussia from its founding in 1525 as the Duchy of Prussia.  The Duchy had evolved out of the Teutonic Order, a Roman Catholic crusader state and theocracy located along the eastern coast of the Baltic Sea.  The Teutonic Knights were under the leadership of a Grand Master, the last of whom, Albert, converted to Protestantism and secularized the lands, which then became the Duchy of Prussia.  The Duchy was initially a vassal of the Kingdom of Poland, as a result of the terms of the Prussian Homage whereby Albert was granted the Duchy as part of the terms of peace following the Prussian War.  When the main line of Prussian Hohenzollerns died out in 1618, the Duchy passed to a different branch of the family, who also reigned as Electors of Brandenburg in the Holy Roman Empire.  While still nominally two different territories, Prussia under the suzerainty of Poland and Brandenburg under the suzerainty of the Holy Roman Empire, the two states are known together historiographically as Brandenburg-Prussia.  Following the Second Northern War, a series of treaties freed the Duchy of Prussia from any vassalage to any other state, making it a fully sovereign Duchy in its own right.  This complex situation (where the Hohenzollern ruler of the independent Duchy of Prussia was also a subject of the Holy Roman Emperor as Elector of Brandenburg) laid the eventual groundwork for the establishment of the Kingdom of Prussia in 1701.  For diplomatic reasons, the rulers of the state were known as the King in Prussia from 1701 to 1772; largely because they still owed fealty to the Emperor as Electors of Brandenburg, the "King in Prussia" title (as opposed to "King of Prussia") avoided offending the Emperor.  As the Prussian state grew through several wars and diplomatic moves throughout the 18th century, it became apparent that Prussia had become a Great Power that did not need to submit meekly to the Holy Roman Empire.  By 1772, the pretense was dropped, and the style "King of Prussia" was adopted.  Thus it remained until 1871, when in the aftermath of the Franco-Prussian War, the King of Prussia Wilhelm I was crowned German Emperor.  From that point forward, though the Kingdom of Prussia retained its status as a constituent state of the German Empire, all remaining Kings of Prussia also served as German Emperor, and that title took precedence. The Duchy of Württemberg (German: "Herzogtum Württemberg" ) was a duchy located in the south-western part of the Holy Roman Empire.  It was a member of the Holy Roman Empire from 1495 to 1806.  The dukedom's long survival for nearly four centuries was mainly due to its size, being larger than its immediate neighbors.  During the Protestant Reformation, Württemberg faced great pressure from the Holy Roman Empire to remain a member.  Württemberg resisted repeated French invasions in the 17th and 18th centuries.  Württemberg was directly in the path of French and Austrian armies who were engaged in the long rivalry between the House of Bourbon and the House of Habsburg.  In 1803, Napoleon raised the duchy to be the Electorate of Württemberg of the Holy Roman Empire, and when he abolished the Empire in 1806, the Electorate was elevated as the Kingdom of Württemberg. The uniformity policy was the concept of implementing Swedish law to the dominions of Sweden during the latter's time as an empire.  It is symbolized by the slogan unus rex, una lex et grex unus ("one king, one law, one people") possibly coined by Johan Skytte, governor-general in Swedish Estonia, Ingria and Livonia.  However, the phrase is also found in the debates on the possible union of Scotland and England in 1607, when Sir Edwyn Sandys noted King James VI & I's view that for a perfect union there should be unus rex, unus grex, una lex.  Most notably, the uniformity policy aimed at abolishing serfdom then common in Estonia, Livonia and the Swedish dominons in the Holy Roman Empire (Ingermanland naturally had a free peasantry).  While implemented in Livonia against the will of the local Baltic German nobles, the Estonian and Pomeranian peasants remained serfs: Estonia had voluntarily submitted to Sweden and thus had been given leeway in keeping the traditional local law code, while Swedish Pomerania had retained its traditional law code when, on behalf of the then ruling Swedish high nobility, the Peace of Westphalia granted it to Sweden while remaining part of the Holy Roman Empire, and not in a formal cession which would have resulted in the implementation of Swedish law.  Swedish law was thus only introduced to Swedish Pomerania after the dissolution of the Holy Roman Empire in 1806. Jurij Slatkonja (German: "Georg von Slatkonia" , also "Jurij Chrysippus," Slovenian: "Jurij Slatkonja"; 21 March 1456–26 April 1522) was a Carniolan choirmaster and the first residential Bishop of Vienna.  He was also the first owner of an ex libris among the Slovenes.  His crest contained a golden horse, from which comes his surname (Slovene "slat" [= "zlat"] 'golden' + "konj" 'horse'). Karl Anselm, 4th Prince of Thurn and Taxis, full German name: "Karl Anselm Fürst von Thurn und Taxis" (2 June 1733, Frankfurt am Main, Free Imperial City of Frankfurt, Holy Roman Empire – 13 November 1805, Winzer bei Regensburg, Electorate of Bavaria, Holy Roman Empire) was the fourth Prince of Thurn and Taxis, Postmaster General of the Imperial Reichspost, and Head of the Princely House of Thurn and Taxis from 17 March 1773 until his death on 13 November 1805.  Karl Anselm served as "Prinzipalkommissar" at the Perpetual Imperial Diet in Regensburg for Joseph II, Holy Roman Emperor and Francis II, Holy Roman Emperor from 1773 to 1797. The Imperial Military Constitution (German: "Reichsheeresverfassung" , also called the "Reichskriegsverfassung") of the Holy Roman Empire, like the rest of the imperial constitution, grew out of various laws and governed the establishment of military forces within the Empire.  It was the basis for the establishment of the Army of the Holy Roman Empire ("Reichsarmee"), which was under the supreme command of the Emperor but was distinct from his Imperial Troops, as it could only be deployed by the Imperial Diet.  The last Imperial Defence Order ("Reichsdefensionalordnung"), entitled "Reichsgutachten in puncto securitatis", of 13/23 May 1681, completed the military constitution of the Holy Roman Empire. Yuriy Trubetskoy ("Jurij Trubetsky", "Jerzy Trubecki", "Jurij Trubiacki", "Юрий Петрович Трубецкий ", "Юрій Петрович Трубецький ", "Juri Petrovitz Troebieskoy"; ca 1643 – 12 July 1679 buried in Troitsky monastery) was a Ruthenian Prince, boyar of the Trubetsky family.  In 1657, Prince Jurij Trubetsky went to Moscow with his uncle Aleksandr Yurievitch Trubetzkoy (?  - Poland after 1657).  Stolnik in Moscow in 1660, he was given a boyar title by Tsar Alexis I of Russia in 1673.  In the late 17th century, the weakened Republic of Both Nations under King Jan III Sobieski in alliance with the forces of Leopold I, Holy Roman Emperor, dealt the crushing defeats to the Ottoman Empire; Jerzy Trubecki was the Polish wojewoda of Kiev Voivodeship, 1673.  He hold the scepter at the coronation of Fedor Alexeevitch in 1676.
