Question: The King of England, who William Scott presided over trials resulting from this purge of the administration, reigned for how long?

full_context: Document 1: William Scott (Missouri): William Scott (June 7, 1804 – 1862) was an American lawyer and judge who served on the Supreme Court of Missouri from 1841 to 1849 and from 1851 to 1862. He also served on the Jefferson City Circuit Court. Justice Scott was the author of the majority opinion in "Scott v. Emerson", 15 Missouri 572 (1852), which was part of the "Dred Scott v. Sandford" case. Scott's opinion, which overturned well-established precedent in Missouri, set the stage for Dred Scott's case in the Supreme Court.
Document 2: William Scott (justice): Sir William Scott (d. 1350s) was an English lawyer, and Chief Justice of the King's Bench from 8 January 1341 to 26 November 1346. Originally from Yorkshire – probably Birthwaite in Kexbrough – Scott as Chief Justice presided over trials resulting from Edward III's purge of the administration the previous years. Among those tried was William de la Pole. After retiring from this position, Scott largely withdrew from public life, probably because of ill health. He returned to Yorkshire to attend to his estates. The Oxford Dictionary of National Biography says that he "was still alive on 10 March 1352...but was certainly dead by 11 May 1356, and probably by 1354".
Document 3: William Scheves: William Scheves (died 1497) was the second Archbishop of St. Andrews. His parentage is obscure, but he was probably the illegitimate son of a royal clerk, John Scheves. He is said to have spent several years abroad and probably studied at the University of Louvain. He spent several years at the University of St Andrews as an administrator. In his earlier ecclesiastical career, he had been "clericus regiae" (royal cleric) and master of the hospital of Brechin. In 1474 he was provided unsuccessful to the Archdeaconry of Dunblane, but by the beginning of 1477 he was Archdeacon of St Andrews and coadjutor (successor) and vicar-general of the archdiocese. After the deposition of Archbishop Patrick Graham in 1478, he succeeded to the archbishopric, apparently receiving the papal pall while in the presence of King James III and many of the nobility at Holyrood.
Document 4: John Bacon (judge): Bacon is first mentioned as acting in the capacity of attorney to Queen Eleanor in 1278-9, and is described in certain indentures of the exchequer, dated 1288, as 'clericus Regis' and 'custos rotulorum et brevium de Banco' and 'Regis thesauriarius et camerarius,' his business being to keep a list of the cases argued in the common pleas, and to transmit records thereof, and also 'pedes chirographorum,' i.e. memoranda of fines levied throughout the country, to the treasurers and chamberlains of the exchequer, of the receipt of which the indentures already mentioned were acknowledgments. The 'chirographa,' or fines in question, were fictitious suits, by means of which it was the custom to bar entails and convey the landed property of married women. Bacon seems to have held this post as late as 1309. In 1291 he was entrusted with the charge of Leeds Castle in Kent (a royal residence). In 1313 he was appointed to a justiceship of the common pleas, and in the same year we read of his being retained in London to advise the king upon some important matters. In 1314 he was made one of the commissioners of oyer and terminer for the counties of Norfolk and Suffolk, to try certain assessors and collectors of the revenue charged with breach of trust. In 1315 William de Beresford, the chief justice of the common pleas, being suddenly summoned to the king, the business of the court devolved upon Thrikingham and Bacon exclusively. We may conjecture that it was not very promptly or efficiently despatched, for it was but a short time since he had been enjoined to pay a more diligent attention to duty. In 1317 he was summoned with the rest of the judges to parliament at Lincoln, but the invasion of the Scots in that year caused the postponement of the parliament sine die. In 1320 he was placed on a commission to try certain persons charged with debasing and counterfeiting the coinage in the counties of Essex, Norfolk, and Suffolk, and in 1321 upon another directed to inquire into offences committed by sheriffs and other legal functionaries under colour of their official duties in the counties of Norfolk, Suffolk, Cambridge, and Huntingdon. He appears to have died in this year, Stonore being appointed justice of the common pleas in his place. He had landed property in Reston, Hemingston, Cleydon, and Akenham, places all of them in the county of Suffolk, and also in Essex, and at Shouldham in Norfolk.
Document 5: Issue of Edward III of England: King Edward III of England is the ancestor of many European monarchs (as well as the issue of many English Dukes, Earls and Viscounts) through his sons Lionel of Antwerp, 1st Duke of Clarence; John of Gaunt, 1st Duke of Lancaster; Edmund of Langley, 1st Duke of York and Thomas of Woodstock, 1st Duke of Gloucester. All of Edward's legitimate children were by his wife Philippa of Hainault.
Document 6: Edward IV of England: Edward IV (28 April 1442 – 9 April 1483) was the King of England from 4 March 1461 to 3 October 1470, and again from 11 April 1471 until his death in 1483. He was the first Yorkist King of England. The first half of his rule was marred by the violence associated with the Wars of the Roses, but he overcame the Lancastrian challenge to the throne at Tewkesbury in 1471 to reign in peace until his sudden death. Before becoming king, he was 4th Duke of York, 7th Earl of March, 5th Earl of Cambridge and 9th Earl of Ulster. He was also the 65th Knight of the Order of the Golden Fleece.
Document 7: Robert Lauder of Quarrelwood: Sir Robert de Lawedre (Lauder), Knt., of Quarrelwood (died about 1370) was Justiciar of Scotia, a Scottish soldier of great prominence and Captain of Urquhart Castle. He is recorded by Fordun, in his "Scotichronicon", and in "Extracta ex variis Cronicis Scocie" as "Robertus de Lavedir 'the good'"
Document 8: William Sinclair (bishop): William de Sancto Claro, or simply William Sinclair († 1337), was a 14th-century bishop of Dunkeld. He was the son of Amicia de Roskelyn and Sir William Sinclair, Baron of Roslin. He was the brother of Sir Henry Sinclair, baron of Roslin. After the death of Bishop Matthew de Crambeth in 1309, William was elected to the bishopric. The following year, on 24 February 1310, William was one of twelve Scottish bishops to swear fealty to King Robert the Brus. However, king Edward II of England had his own candidate in mind, John de Leck. William went to the Holy See, where his election was contested by the said John. The diocese of Dunkeld lay vacant for three years. Pope Clement V appointed Cardinal James, cardinal deacon of St George in Velabro, to judge the issue. However, the issue was more or less resolved when, on 22 May 1311, John de Leck was promoted to the Archbishopric of Dublin. When John de Leck took over the see of Dublin on 20 July, he retired from the dispute. The pope then declared William's election canonical, and sent him to Cardinal Berenger Fredoli, bishop of Tusculum, in order to be consecrated. On 3 February 1313 king Edward II issued a safe-conduct to William, clearly indicating that the bishop was planning to arrive in England on his way back to Scotland, however Edward demanded cooperation in political matters as a condition. William became a frequent witness to King Robert's charters, but that did not prevent Bishop William, on 24 September 1332, being present at the coronation of Edward Balliol. Bishop William attended the latter's parliaments. William died on 27 June 1337, and was buried in the choir of Dunkeld Cathedral.
Document 9: Edward III of England: Edward III (13 November 1312 – 21 June 1377) was King of England from 25 January 1327 until his death; he is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II. Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe. His long reign of 50 years was the second longest in medieval England and saw vital developments in legislation and government—in particular the evolution of the English parliament—as well as the ravages of the Black Death.
Document 10: Richard II of England: Richard II (6 January 1367 – c. 14 February 1400), also known as Richard of Bordeaux, was King of England from 1377 until he was deposed on 30 September 1399. Richard, a son of Edward, the Black Prince, was born in Bordeaux during the reign of his grandfather, Edward III. His father was Prince of Aquitaine. Richard was the younger brother of Edward of Angoulême, upon whose death Richard, at three years of age, became second in line to the throne after his father. Upon the death of Richard's father prior to the death of Edward III, Richard, by primogeniture, became the heir apparent to the throne. With Edward III's death the following year, Richard succeeded to the throne at the age of ten.
Document 11: Henry Green (justice): Sir Henry Green, Lord of Boughton,(died 6 August 1369) was an English lawyer, and Chief Justice of the King's Bench from 24 May 1361 to 29 October 1365. He was speaker of the House of Lords in two Parliaments (1363–64). Although no formal records exist to confirm it, he almost certainly was the son of Sir Thomas de Grene, Lord of Boughton and Lucy la Zouche, daughter of Eudo la Zouche and Millicent de Cantilupe. Early in his career he served both Queen consort Isabel and her grandson, Edward the Black Prince. He was made justice of the Court of Common Pleas in 1354, and knighted by King Edward III. In 1357 he was excommunicated for non-appearance at the trial of Thomas de Lisle, bishop of Ely, in Avignon.
Document 12: Edward III of England: Edward III (13 November 1312 – 21 June 1377) was King of England from 25 January 1327 until his death; he is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II. Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe. His long reign of 50 years was the second longest in medieval England and saw vital developments in legislation and government—in particular the evolution of the English parliament—as well as the ravages of the Black Death.
Document 13: Edward I of England: Edward I (17/18 June 1239 – 7 July 1307), also known as Edward Longshanks and the Hammer of the Scots (Latin: "Malleus Scotorum" ), was King of England from 1272 to 1307. He spent much of his reign reforming royal administration and common law. Through an extensive legal inquiry, Edward investigated the tenure of various feudal liberties, while the law was reformed through a series of statutes regulating criminal and property law. Increasingly, however, Edward's attention was drawn towards military affairs.
Document 14: Edward V of England: Edward V (2 November 1470 – ) was King of England from his father Edward IV's death on 9 April 1483 until 26 June of the same year. He was never crowned, and his 78-day reign was dominated by the influence of his uncle and Lord Protector, Richard, Duke of Gloucester, who succeeded him as Richard III on 26 June 1483; this was confirmed by the Act entitled Titulus Regius, which denounced any further claims through his father's heirs.
Document 15: Edward II of England: Edward II (25 April 1284 – 21 September 1327), also called Edward of Caernarfon, was King of England from 1307 until he was deposed in January 1327. The fourth son of Edward I, Edward became the heir to the throne following the death of his older brother Alphonso. Beginning in 1300, Edward accompanied his father on campaigns to pacify Scotland, and in 1306 he was knighted in a grand ceremony at Westminster Abbey. Edward succeeded to the throne in 1307, following his father's death. In 1308, he married Isabella of France, the daughter of the powerful King Philip IV, as part of a long-running effort to resolve the tensions between the English and French crowns.
