Context: The Battle of Tachov (German: "Schlacht bei Tachau" ) or Battle of Mies (German: "Schlacht bei Mies" ) was a battle fought on 4 August 1427 near the Bohemian towns of Tachov ("Tachau") and Stříbro ("Mies").  The Hussites won over the armies led by the Cardinal Henry Beaufort of England and Archbishop of Trier Otto von Ziegenhain. Simon de Langham (1310 – 22 July 1376) was an English clergyman who was Archbishop of Canterbury and a cardinal. Hans von Hentig (9 June 1887 in Berlin – 6 July 1974 in Bad Tölz) was a German criminal psychologist and politician.He was the second son of lawyer Otto von Hentig (1852–1934) . His older brother was later diplomat Werner Otto von Hentig.  Otto von Hentig was one of the leading lawyers in Berlin.  Hans von Hentig was instrumental in the setting up of a short-lived Bavarian Soviet Republic in 1919.  During the 1920s he was a prominent exponent of National Bolshevism.  He emigrated to United States in 1935.  Hans von Hentig worked on Yale University. George Walker (c.1581–1651) was an English clergyman, known for his strong Puritan views.  He was imprisoned in 1638 by William Laud, Archbishop of Canterbury, an affair that was later raised against Laud at his trial.  He became a member of the Westminster Assembly in 1643. Narcissus Marsh (20 December 1638 – 2 November 1713) was an English clergyman who was successively Church of Ireland Bishop of Ferns and Leighlin, Archbishop of Cashel, Archbishop of Dublin and Archbishop of Armagh. William I, or in German Wilhelm I (full name: "William Frederick Louis of Hohenzollern", German: "Wilhelm Friedrich Ludwig von Hohenzollern" , 22 March 1797 – 9 March 1888), of the House of Hohenzollern was King of Prussia from 2 January 1861 and the first German Emperor from 1 January 1871 to his death, the first Head of State of a united Germany.  Under the leadership of William and his Minister President Otto von Bismarck, Prussia achieved the unification of Germany and the establishment of the German Empire.  Despite his long support of Otto von Bismarck as Minister President, William held strong reservations about some of Bismarck's more reactionary policies, including his anti-Catholicism and tough handling of subordinates.  Contrary to the domineering Bismarck, William was described as polite, gentlemanly and, while a staunch conservative, more open to certain classical liberal ideas than his grandson Wilhelm II. John II, Count of Ziegenhain (died 14 February 1450) was the second son of Count Gottfried VIII of Ziegenhain and his wife Agnes of Brunswick.  He was the last reigning Count of Ziegenhain and Nidda.  He probably owed His nickname "the Strong" to his obesity, although he is said to have possessed an extraordinary muscle strength as a young man.  His younger brother Otto was Archbishop of Trier from 1419 until his death in 1430. John Joscelyn or John Joscelin (1529–1603) was an English clergyman and antiquarian as well as secretary to Matthew Parker, an Archbishop of Canterbury during the reign of Queen Elizabeth I of England.  Joscelyn was involved in Parker's attempts to secure and publish medieval manuscripts on church history, and was one of the first scholars of the Old English language.  He also studied the early law codes of England.  His Old English dictionary, although not published during his lifetime, contributed greatly to the study of that language.  Many of his manuscripts and papers eventually became part of the collections of Cambridge University, Oxford University, or the British Library. Henry Beaufort (c. 1375 – 11 April 1447) was a medieval English clergyman, Bishop of Winchester, a member of the royal house of Plantagenet, and a Cardinal of the Roman Catholic Church. John of Tynemouth (died 1221) was a medieval English clergyman and canon lawyer.  He was among the first teachers of canon law at what later became Oxford University, where he was by 1188.  By the late 1190s John had joined the household of the Archbishop of Canterbury, Hubert Walter.  Besides his position in the household, he also held a number of ecclesiastical positions, which earned him a substantial income.  After Walter's death, John continued to serve as a lawyer as well as hold clerical offices.  He died in 1221 and a number of his writings survive.
