question: Wilhelm Wiegand is best known for and his publications involving a man that was King of Prussia beginning in what year?
answer: 1740
context: Title: Frederick III, German Emperor
  Passage: Frederick III (German: "Friedrich" ; 18 October 1831 – 15 June 1888) was German Emperor and King of Prussia for ninety-nine days in 1888, the Year of the Three Emperors.  Friedrich Wilhelm Nikolaus Karl, known informally as "Fritz", was the only son of Emperor Wilhelm I and was raised in his family's tradition of military service.  Although celebrated as a young man for his leadership and successes during the Second Schleswig, Austro-Prussian and Franco-Prussian wars, he nevertheless professed a hatred of warfare and was praised by friends and enemies alike for his humane conduct.  Following the unification of Germany in 1871 his father, then King of Prussia, became the German Emperor.  Upon Wilhelm's death at the age of ninety on 9 March 1888, the thrones passed to Frederick, who had by then been German Crown Prince for seventeen years and Crown Prince of Prussia for twenty-seven years.  Frederick was suffering from cancer of the larynx when he died on 15 June 1888, aged fifty-six, following unsuccessful medical treatments for his condition.
  Title: Wilhelm Wiegand
  Passage: Wilhelm Wiegand (5 November 1851, Ellrich – 8 March 1915, Strasbourg) was a German archivist and historian.  He is best known for his research of Alsatian history and his publications involving Frederick the Great.
  Title: Justice of the Common Pleas
  Passage: Justice of the Common Pleas was a puisne judicial position within the Court of Common Pleas of England and Wales, under the Chief Justice.  The Common Pleas was the primary court of common law within England and Wales, dealing with "common" pleas (civil matters between subject and subject).  It was created out of the common law jurisdiction of the Exchequer of Pleas, with splits forming during the 1190s and the division becoming formal by the beginning of the 13th century.  The court became a key part of the Westminster courts, along with the Exchequer of Pleas (qualified to hear cases involving revenue owed to the King) and the Court of King's Bench (authorised to hear cases involving the King), but with the Writ of Quominus and the Statute of Westminster, both tried to extend their jurisdiction into the realm of common pleas.  As a result, the courts jockeyed for power.  In 1828 Henry Brougham, a Member of Parliament, complained in Parliament that as long as there were three courts unevenness was inevitable, saying that "It is not in the power of the courts, even if all were monopolies and other restrictions done away, to distribute business equally, as long as suitors are left free to choose their own tribunal", and that there would always be a favourite court, which would therefore attract the best lawyers and judges and entrench its position.  The outcome was the Supreme Court of Judicature Act 1873, under which all the central courts were made part of a single Supreme Court of Judicature.  Eventually the government created a High Court of Justice under Lord Coleridge by an Order in Council of 16 December 1880.  At this point, the Common Pleas formally ceased to exist.
  Title: Frederick the Great
  Passage: Frederick II (German: "Friedrich" ; 24 January 171217 August 1786) was King of Prussia from 1740 until 1786, the longest reign of any Hohenzollern king.  His most significant accomplishments during his reign included his military victories, his reorganization of Prussian armies, his patronage of the arts and the Enlightenment in Prussia, and his final success against great odds in the Seven Years' War.  Frederick was the last titled King in Prussia and declared himself King of Prussia after achieving full sovereignty for all historical Prussian lands.  Prussia had greatly increased its territories and became a leading military power in Europe under his rule.  He became known as Frederick the Great ("Friedrich der Große ") and was affectionately nicknamed "Der Alte Fritz " ("Old Fritz") by the Prussian and later by all German people.
