Each verse ends with: Context_2 : Emmett Miller (February 2, 1900 – March 29, 1962) was an American minstrel show performer and recording artist known for his falsetto, yodel-like voice. Little remembered today, Miller was a major influence on many country music singers, including Hank Williams, Jimmie Rodgers, Bob Wills, Milton Brown, Tommy Duncan, and Merle Haggard. His music is a link between old-time Southern music, minstrelsy, jazz, and Western swing. Context_3 : Thomas Elmer Duncan (January 11, 1911 – July 25, 1967), better known as Tommy Duncan, was a pioneering American Western swing vocalist and songwriter who gained fame in the 1930s as a founding member of The Texas Playboys.

Context_1 : The Nobel Prize in Chemistry (Swedish: "Nobelpriset i kemi" ) is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields of chemistry. It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel, who died in 1896. These prizes are awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members elected by the Royal Swedish Academy of Sciences. The first Nobel Prize in Chemistry was awarded in 1901 to Jacobus Henricus van 't Hoff, of the Netherlands. Each recipient receives a medal, a diploma and a monetary award prize that has varied throughout the years. In 1901, van 't Hoff received 150,782 SEK, which is equal to 7,731,004 SEK in December 2007. The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death. Context_2 : The Nobel Prizes are awarded annually by the Royal Swedish Academy of Sciences, the Swedish Academy, the Karolinska Institute, and the Norwegian Nobel Committee to individuals who make outstanding contributions in the fields of Chemistry, Physics, Literature, Peace, Physiology or Medicine and Economics. All but the economics prize were established by the 1895 will of Alfred Nobel, which dictates that the awards should be administered by the Nobel Foundation. The Nobel prize in Economics, or The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, was established in 1968 by the Sveriges Riksbank, the central bank of Sweden, for outstanding contributions in the field of Economics. Each prize is awarded by a separate committee; the Royal Swedish Academy of Sciences awards the Prizes in Physics, Chemistry, and Economics, the Swedish Academy awards the Prize in Literature, the Karolinska Institute awards the Prize in Physiology or Medicine, and the Norwegian Nobel Committee awards the Prize in Peace. Each recipient receives a medal, a diploma and a cash prize that has varied throughout the years. Context_3 : This is a list of Danish Nobel laureates. Since the Nobel Prize was established per the will of Swedish inventor Alfred Nobel in 1895, 12 of the prize winners have been from Denmark. The first Danish Nobel laureate was Niels Ryberg Finsen, who won a Nobel Prize for medicine in 1903 for his work in using light therapy to treat diseases. The most recent Danish Nobel Prize winner was Jens Skou who won the prize in chemistry for his discovery over the enzyme, Na+/K+-ATPase in 1997. To date, of the 13 Nobel Prizes won by Danish people, 5 have been for medicine, 3 have been for physics, 3 have been for literature, 1 has been for chemistry and one has been for peace. Context_4 : Lars Onsager (November 27, 1903 – October 5, 1976) was a Norwegian-born American physical chemist and theoretical physicist. He held the Gibbs Professorship of Theoretical Chemistry at Yale University. He was awarded the Nobel Prize in Chemistry in 1968. Context_5 : The Leverhulme Medal is awarded by the Royal Society every three years "for an outstandingly significant contribution in the field of pure or applied chemistry or engineering, including chemical engineering". It was created in 1960 after a donation by the Leverhulme Trust to mark the 300-year anniversary of the foundation of the Royal Society, and is accompanied by a £2000 gift. Since its creation it has been awarded 17 times, and unlike other Royal Society medals such as the Royal Medal, it has never been awarded to a woman or to the same person multiple times. Citizens of the United Kingdom have won the medal 16 out of the 17 times; the only foreign recipient was Man Mohan Sharma, an Indian citizen who was awarded the medal in 1996 "for his work on the dynamics of multi-phase chemical reactions in industrial processes". Two of the Leverhulme Medal winners also won the Nobel Prize in Chemistry: Archer John Porter Martin, who won the medal in 1963 for "his distinguished and fundamental discoveries in chromatography and its application" and the Nobel Prize in 1952, and Cyril Norman Hinshelwood, who won the medal in 1960 for "his outstanding contributions to physical chemistry" and the Nobel Prize in 1956. Context_6 : Hendrik Antoon Lorentz (18 July 1853 – 4 February 1928) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Pieter Zeeman for the discovery and theoretical explanation of the Zeeman effect. He also derived the transformation equations underpinning Albert Einstein's theory of special relativity. Context_7 : The Nobel Prize in Physiology or Medicine (Swedish: "Nobelpriset i fysiologi eller medicin" ) is awarded annually by the Swedish Karolinska Institute to scientists and doctors in the various fields of physiology or medicine. It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel (who died in 1896), awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members and an executive secretary elected by the Karolinska Institute. While commonly referred to as the Nobel Prize in Medicine, Nobel specifically stated that the prize be awarded for "physiology or medicine" in his will. Because of this, the prize can be awarded in a broader range of fields. The first Nobel Prize in Physiology or Medicine was awarded in 1901 to Emil Adolf von Behring, of Germany. Each recipient receives a medal, a diploma and a monetary award that has varied throughout the years. In 1901, von Behring received 150,782 SEK, which is equal to 7,731,004 SEK in December 2008. In 2013, the prize was awarded to James E. Rothman, Randy W. Schekman and Thomas C. Südhof; they were recognised "after discovering how cells precisely transport material". The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death. Context_8 : The Nobel Prize in Physics (Swedish: "Nobelpriset i fysik" ) is a yearly award given by the Royal Swedish Academy of Sciences for those who conferred the most outstanding contributions for mankind in the field of physics. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901; the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine. Context_9 : Since 1901, the Nobel Prize in Literature (Swedish: "Nobelpriset i litteratur" ) has been awarded annually to an author from any country who has, in the words of the will of Alfred Nobel, produced "in the field of literature the most outstanding work in an ideal direction" (original Swedish: "den som inom litteraturen har producerat det mest framstående verket i en idealisk riktning"). Though individual works are sometimes cited as being particularly noteworthy, here "work" refers to an author's work as a whole. The Swedish Academy decides who, if anyone, will receive the prize in any given year. The academy announces the name of the chosen laureate in early October. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895; the others are the Nobel Prize in Chemistry, Nobel Prize in Physics, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.

Context_1 : 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. Context_2 : The Crown of the Immacculate Conception, known as the Crown of the Andes — known in Spanish as La Corona de los Andes and as "La Corona de Nuestra Señora de la Asunción de Popayán " — is a votive crown originally made for a larger than life-size statue of the Virgin in the cathedral of Popayán, Colombia. The diadem was made around 1660, and the arches were added around 1770. The crown purportedly includes emeralds taken from the captured Inca Emperor Atahualpa (1497–1533). In 1936, the crown was sold by its owners to an American businessman and it has remained in the United States ever since. As of December 2015, the crown belongs to the collection of the Metropolitan Museum of Art in New York City. Context_3 : Holy Roman Empress or Empress of the Holy Roman Empire is the title given to the consort (wife) or regent of the Holy Roman Emperor. The elective dignity of Holy Roman Emperor was restricted to males only, therefore there was never a Holy Roman Empress regnant, though women such as Theophanu or Maria Theresa of Austria, who controlled the power of rule, served as de facto Empresses regnant. Context_4 : Francis I (German: "Franz Stefan" , French: "François Étienne" ; 8 December 1708 – 18 August 1765) was Holy Roman Emperor and Grand Duke of Tuscany, though his wife effectively executed the real powers of those positions. With his wife, Maria Theresa, he was the founder of the Habsburg-Lorraine dynasty. From 1728 until 1737 he was Duke of Lorraine. Francis traded the duchy to the ex-Polish king Stanisław Leszczyński in exchange for the Grand Duchy of Tuscany as one of the terms ending the War of the Polish Succession in November 1738. The duchy and the ducal title to Lorraine and Bar passed to King Louis XV of France upon Leszczynski's death in 1766, though Francis and his successors retained the right to style themselves as dukes of Lorraine and Bar. Context_5 : Leopold I (name in full: "Leopold Ignaz Joseph Balthasar Felician"; Hungarian: "I. Lipót" ; 9 June 1640 – 5 May 1705) was Holy Roman Emperor, King of Hungary, Croatia, and Bohemia. The second son of Ferdinand III, Holy Roman Emperor, by his first wife, Maria Anna of Spain, Leopold became heir apparent in 1654 by the death of his elder brother Ferdinand IV. Elected in 1658, Leopold ruled the Holy Roman Empire until his death in 1705. Context_6 : The Concordat of Worms (Latin: "Concordatum Wormatiense" ), sometimes called the Pactum Calixtinum by papal historians, was an agreement between Pope Calixtus II and Holy Roman Emperor Henry V on September 23, 1122, near the city of Worms. It brought to an end the first phase of the power struggle between the Papacy and the Holy Roman Emperors and has been interpreted as containing within itself the germ of nation-based sovereignty that would one day be confirmed in the Treaty of Westphalia (1648). In part this was an unforeseen result of strategic maneuvering between the Church and the European sovereigns over political control within their domains. The King was recognised as having the right to invest bishops with secular authority ("by the lance") in the territories they governed, but not with sacred authority ("by ring and staff"). The result was that bishops owed allegiance in worldly matters both to the pope and to the king, for they were obliged to affirm the right of the sovereign to call upon them for military support, under his oath of fealty. Previous Holy Roman Emperors had thought it their right, granted by God, to name Church officials within their territories (such as bishops) and to confirm the Papal election (and, at times of extraordinary urgency, actually name popes). In fact, the Emperors had been heavily relying on bishops for their secular administration, as they were not hereditary or quasi-hereditary nobility with family interests. A more immediate result of the Investiture struggle identified a proprietary right that adhered to sovereign territory, recognising the right of kings to income from the territory of a vacant diocese and a basis for justifiable taxation. These rights lay outside feudalism, which defined authority in a hierarchy of personal relations, with only a loose relation to territory. The pope emerged as a figure above and out of the direct control of the Holy Roman Emperor. Context_7 : Gerasim Zelić (Serbian: Герасим Зелић ; 1752–1828) was a renowned Serbian Orthodox Church archimandrite, traveller and writer (a contemporary and compatriot of Dositej Obradović). His chief work is "Žitije" (Lives), in three volumes. They are memoirs of his travels throughout western Europe, Russia and Asia Minor from the latter half of the 18th century to the first decade of the 19th century and the famous personalities (Napoleon, Prince Eugène, Viceroy of Naples, Joseph II, Holy Roman Emperor, Leopold II, Holy Roman Emperor, Francis II, Holy Roman Emperor, Semyon Zorich, Catherine the Great, Alexander I of Russia, Stanisław August Poniatowski, Dositej Obradović) he met. He had valuable original notes on people, religions, manners, customs, trade, etc. Context_8 : La corona ("The Crown") is an opera by the composer Christoph Willibald Gluck. It takes the form of an "azione teatrale" in one act. The Italian-language libretto is by Pietro Metastasio. The opera was intended to celebrate the name day of Emperor Francis I on 4 October 1765 but the emperor died in August and it remained unperformed until the 20th century. Context_9 : Maria Josepha of Bavaria (Marie Josephe Antonie Walburga Felicitas Regula, 20 March 173928 May 1767) was Holy Roman Empress, Queen of the Romans, Archduchess of Austria, Grand Duchess of Tuscany, etc. by her marriage to Joseph II, Holy Roman Emperor. By birth, she was a Princess and Duchess of Bavaria as the daughter of Charles VII, Holy Roman Emperor, Elector of Bavaria, and Archduchess Maria Amalia of Austria. Context_10 : 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. fact_1 :  The opera was intended to celebrate the name day of Emperor Francis I on 4 October 1765 but the emperor died in August and it remained unperformed until the 20th century. fact_2 : Francis I (German: "Franz Stefan" , French: "François Étienne" ; 8 December 1708 – 18 August 1765) was Holy Roman Emperor and Grand Duke of Tuscany, though his wife effectively executed the real powers of those positions. Question: In what year was the Holy Roman Emperor whose name day the opera "La corona" was intended to celebrate born?

1708
