Question: Who is an advocate for the Pan-European movement and is part of the Order of the Golden Fleece?
Context: The Order of the Golden Fleece (Spanish: "Orden del Toisón de Oro" , German: "Orden vom Goldenen Vlies" ) is a Roman Catholic order of chivalry founded in Bruges by the Burgundian duke Philip the Good in 1430, to celebrate his marriage to the Portuguese princess Isabella.  It became one of the most prestigious orders in Europe.  Today, two branches of the Order exist, namely the Spanish and the Austrian Fleece; the current grand masters are Felipe VI, King of Spain, and Karl von Habsburg, grandson of Emperor Charles I of Austria, respectively.  The chaplain of the Austrian branch is Cardinal "Graf" von Schönborn, Archbishop of Vienna. Karl von Habsburg (Karl Thomas Robert Maria Franziskus Georg Bahnam; born 11 January 1961), also known as "Karl of Austria" and referred to in Austria as "Karl Habsburg-Lothringen", is an Austrian politician, the current head of the House of Habsburg-Lorraine which ruled the lands of the Habsburg Monarchy, the Empire of Austria the Austro-Hungarian Monarchy, and the Kingdom of Hungary as well as the Crown lands of Bohemia and Croatia by hereditary right until the end of World War I. Born in Starnberg, Germany, in 1961, he is the son of Otto von Habsburg and Princess Regina of Saxe-Meiningen, and the grandson of the last Austrian emperor, Charles I.  He served as a Member of the European Parliament for the Austrian People's Party 1996–1999.  Like his father, he is known as an advocate for the Pan-European movement. The Order of the Golden Fleece (Georgian: ოქროს საწმისის ორდენი , "ok'ros sats'misis ordeni") is an honor awarded by the government of Georgia.  It was established in 1998 and comes next in rank to the Order of St. Nicholas.  The Order is named after the mythical Golden Fleece, which was held in Colchis in what is now western Georgia. In Greek mythology, the Golden Fleece (Greek: χρυσόμαλλον δέρας "chrysómallon déras") is the fleece of the gold-haired winged ram, which was held in Colchis.  The fleece is a symbol of authority and kingship.  It figures in the tale of the hero Jason and his crew of Argonauts, who set out on a quest for the fleece by order of King Pelias, in order to place Jason rightfully on the throne of Iolcus in Thessaly.  Through the help of Medea, they acquire the Golden Fleece.  The story is of great antiquity and was current in the time of Homer (eighth century BC).  It survives in various forms, among which the details vary. The Golden Fleece Tunnel, is a gold mining site in the Westville gold mining district in Placer County, California.  The mine is located 2 miles northeast of the former mining town Westville, California, north to the Foresthill Divide Road.  It has a 3000 ft tunnel and was operated successfully by the Golden Fleece Mining and Milling Company (New York).  The mine is no longer in operation.  Other nearby mines are the Hogsback Tunnel and the Union Tunnel. The Golden Fleece Award (1975–1988) was a tongue-in-cheek award given to public officials in the United States for their squandering of public money, its name sardonically purloined from the actual Order of the Golden Fleece, a prestigious chivalric award created in the late-15th Century, and a play on the transitive verb "fleece", as in charging excessively for goods or services.  United States Senator William Proxmire, a Democrat from Wisconsin, began to issue the Golden Fleece Award in 1975 in monthly press releases. "The Washington Post" once referred to the award as "the most successful public relations device in politics today."  Senator Robert Byrd of West Virginia, referred to the award as being "as much a part of the Senate as quorum calls and filibusters." Assert (17 April 1979 – 1995) was an Irish Thoroughbred racehorse and sire.  As a two-year-old he was beaten by Golden Fleece on his debut but went on to win the Beresford Stakes.  In the following year he was again beaten by Golden Fleece in a trial race but went on to win four Group One races: the Prix du Jockey Club, Irish Derby, Benson & Hedges Gold Cup and Joe McGrath Memorial Stakes.  He was rated the best middle-distance horse in Europe in 1982 by Timeform.  He was retired to stud at the end of his three-year-old season and became a successful sire of winners. Otto von Habsburg (20 November 1912 4 July 2011), also known by his traditional royal titulature of Archduke Otto of Austria, was the last Crown Prince of Austria-Hungary from 1916 until the dissolution of the empire in 1919, a realm which comprised modern-day Austria, Hungary, Bosnia and Herzegovina, Croatia, the Czech Republic, Slovakia, Slovenia, and parts of Italy, Montenegro, Poland, Romania, Serbia and Ukraine.  He became the pretender to the former thrones, Head of the House of Habsburg-Lorraine, and Sovereign of the Order of the Golden Fleece in 1922, upon the death of his father.  He resigned as Sovereign of the Golden Fleece in 2000 and as head of the Imperial House in 2007. George Washington Peirce (1846 – 1938) was secretary and treasurer of the Golden Fleece Mining and Milling Company (New York), and the Golden Fleece Mining and Milling Company (Iowa). Jean le Fèvre de Saint-Remy or Jean Lefebvre de Saint-Remy (c. 1394 – June 16, 1468) born in Abbeville, was a Burgundian chronicler during the Hundred Years' War and lord ("seigneur") of Saint Remy, la Vacquerie, Avesnes and Morienne.  He is also known by the formal title of authority "Toison d'or" (Golden Fleece) because he served as the King of Arms to the Order of the Golden Fleece.
