Life of Despot Stefan Lazarević

George I (Greek: Γεώργιος Α΄ , "Geórgios I"; born Prince William of Schleswig-Holstein-Sonderburg-Glücksburg; 24 December 1845 – 18 March 1913) was King of Greece from 1863 until his assassination in 1913.
Pre-Columbian Bolivia covers the historical period between 10,000 BCE, when Upper Andes region was first populated and 1532, when Spanish conquistadors invaded Inca empire.
 The Andes region of Pre-Columbian South America was dominated by the Tiwanaku civilization until about 1200, when the regional kingdoms of the Aymara emerged as the most powerful of the ethnic groups living in the densely populated region surrounding Lake Titicaca.
 Power struggles continued until 1450, when the Incas incorporated upper Bolivia into their growing empire.
 Based in present-day Peru, the Incas instituted agriculture and mining practices that rivaled those put in place many years later by European conquerors.
 They also established a strong military force and centralized political power.
 Despite their best efforts, however, the Incas never completely controlled nomadic tribes of the Bolivian lowlands, nor did they fully assimilate the Aymara kingdoms into their society.
 These internal divisions doomed the Inca Empire when European conquerors arrived.
Vladimir (; died 1118) was the Prince of Duklja from 1103 to 1113.
 He was a son of Vladimir, the oldest son of earlier King Mihailo I of Duklja (r. 1050-1081), and thus a nephew of Constantine Bodin (r. 1081-1101).
 He married a daughter of Vukan, the Grand Prince of Serbia (in Raška), thereby ending the civil war between the two polities of Duklja and Raška, with a peace lasting 12 years.
 Vladimir had been appointed the rule of Duklja by his father-in-law, Vukan, after the death of his uncle, former King Kočopar, in Zahumlje.
 He was poisoned in 1118 on the orders of Queen Jaquinta, the widow of his uncle, Constantine Bodin.
 Jaquinta soon appointed her son, George, to the throne.
Levan (Georgian: ლევანი ) (1573–1590), of the Bagrationi Dynasty, was a king of Imereti from 1585 to 1588.
 He succeeded on the death of his father, George II, in 1585 when he was twelve years old.
 With his ascend to the throne, Leon faced a revolt by his own uncle, Constantine, who defied the royal authority and took control of Upper Imereti.
 Leon made an alliance with the Mingrelian prince Mamia IV Dadiani, married his sister Marekhi, and forced Constantine to surrender in 1587.
 A year later, Imereti was invaded by Simon I, the resurgent king of Kartli in eastern Georgia, who sought to reunify all Georgian lands under his crown.
 Leon was forced to flee to the highland province of Lechkhumi, but was soon able to resume the throne after Simon had to return to Kartli.
 However, Leon soon quarreled with his brother-in-law Mamia IV Dadiani who defeated the king and imprisoned him at Fort Shkheti, Mingrelia, where he died in 1590.
The Royal Family Order of Saints Olga and Sophia (Greek: Βασιλικό Οικογενειακό Τάγμα των Αγίων Όλγας και Σοφίας ) was an order of the Greek royal family.
 Reserved for women, it was the third highest honour of the modern Greek state and the Crown after the Order of the Redeemer and the male-only Order of Saints George and Constantine.
 It was instituted in January 1936 by King George II in the memory of his grandmother (Queen Olga) and his mother (Queen Sophia).
The collatio lustralis was a tax on "traders in the widest sense" in the Roman Empire.
 It was instituted by Constantine, although there are some indications that such a tax existed during the reign of Caligula (see Suetonius, "Lives of the Twelve Caesars").
 It applied to both the Western and Eastern Empire.
 It was originally collected in both gold and silver, but only in gold beginning in the late 4th century.
 Like many Roman taxes, it was collected not annually, but (originally) every four years.
The Royal Family Order of Saints George and Constantine (Greek: Βασιλικό Οικογενειακό Τάγμα των Αγίων Γεωργίου και Κωνσταντίνου ) is an order of the Greek royal family.
 For the duration of its existence, it has been the second highest decoration awarded by the modern Greek state and the Greek crown, after the Order of the Redeemer.
 It was instituted in January 1936 by King George II in the memory of his grandfather (King George I) and his father (King Constantine I).
 The order is awarded only to men, while the corresponding Order of Saints Olga and Sophia is reserved for women.
 The order's design was influenced by the royal family's Danish origin, evoking the appearance of the Order of the Dannebrog.
 The order is not awarded since 1975 by the Greek state after the abolition of monarchy and today is awarded only by the Greek Royal Family.
Operation Underworld, published in 2009, is a novel written by author Paddy Kelly.
 The title is taken from the real life operation instituted by the U.S. Navy in February 1942 following the false alert that German saboteurs had invaded the New York City waterfront in preparation for a possible invasion.
 The story is set five weeks after the bombing of Pearl Harbour when America is poorly equipped to enter a world conflict.
 The story revolves around Mike 'Doc' McKeowen, a New York private investigator, Commander Charles Haffenden, a naval intelligence operative and Charles 'Lucky' Luciano, the then head of the New York Mafia.
 The World War II episode was a common story known to New York area Italian-Americans for many years but one that had never been novelized or much written about.
 The characters are involved with murder, a large sum of counterfeit currency and the misconception that a large scale invasion of Nazi saboteurs is underway.
The Royal Order of George I (Greek: Βασιλικόν Τάγμα Γεωργίου Α' ) is a Greek order instituted by King Constantine I in 1915.
 Since the monarchy's abolition in 1973, it is considered a dynastic order of the former Greek royal family.
The Life of Despot Stefan Lazarević (Serbian: Живот деспота Стефана Лазаревића, Житије деспота Стефана Лазаревића ) is a biography on Serbian ruler Stefan Lazarević, authored by Constantine of Kostenets ("the Philosopher") in ca. 1431.
 The biography had been ordered by Serbian Patriarch Nikon following the death of Despot Stefan.
 That order was only fulfilled four years later, when allegedly Despot Stefan himself appeared in Constantine's dream.
 The biography is regarded one of the most interesting in the medieval Serbian literature because it contains not only facts about the Despot's life, but also geographic information and thorough descriptions of numerous historical events.
 Constantine was apparently inspired by Byzantine chronicles.
 The work begins with a geographic description of Serbia's natural beauties, going on to describe its residents, praising their character but also mourning their forthcoming fall to the Turks.
 An exhaustive story of court events and Despot Stefan's life follows, with numerous Biblical and classical references, as well with numerous historical data which have proven invaluable to later historians.
 On several occasions, Constantine used acrostics, with three masterpiece instances: in the introduction verses, in the titles of central chapters, and finally, in the verses telling of his sorrow for the deceased.
