History of the World (often abbreviated HotW) is a board game designed by Ragnar Brothers and originally published in 1991.
 It is played by up to six different players in seven different epochs; each player playing a different empire in each epoch.
Rafael Cardoso (born 4 June 1964) is a Brazilian writer and art historian.
 His published work includes numerous books and essays on the history of art and design in Brazil, mainly focused on the period between 1840 and 1930.
 He has also published four works of fiction, including "Entre as Mulheres" (2007) which first brought him to the attention of an international audience, particularly after its translation into German as "Sechzehn Frauen" (2013).
 His latest novel, "O Remanescente" (2016) was published simultaneously in Brazil, by Companhia das Letras, and Germany, by S. Fischer.
Yun Mu Kwan (연무관, the 'Hall or Institute for Martial Study') is the name of a now all but forgotten Korean karate (Kong Soo Do) style, one of the original five styles or "kwans" that arose in Korea after World War II in emulation of the karate systems practiced in Japan and Okinawa.
 It was begun by Korean karateka Chun Sang Sup, after his return from Japan, where it is generally thought that he studied Shotokan karate under the direct or indirect tutelage of that system's founder, Gichin Funakoshi, an Okinawan educator who first brought karate to Japan from the Ryukyu Islands (annexed by Japan in the nineteenth century).
 Chun taught at the Yun Mu Kwan for only a few years before disappearing during the dislocations of the Korean War which began in 1950.
 Many of his former students eventually began training again at a different location under different teachers and under a new name: Jidokwan (meaning the 'Hall or Institute for Wisdom's Way').
 The Jidokwan was subsequently rolled up, along with most of the other Korean "kwans" into the newly systematized Korean national combat sport of "Taekwondo" (meaning "Foot Fist Way") in the mid 1950s.
 This new, unified Korean martial art emphasized different training and fighting methods than did the older Japanese karate styles from which it was derived, including stressing higher, fancier kicking and more acrobatic movements.
 Unlike the other kwans, however, the "Yun Mu Kwan" name disappeared very early in the history of Korean karate and so was never formally consolidated into the new Korean national sport of taekwondo—although some practitioners of Korean karate today still make use of the name.
 Most, but not all, have adopted the techniques, training methods and competitive rules which characterize modern taekwondo.
The European Union (Withdrawal) Bill, also known as the Repeal Bill or the Great Repeal Bill, is a bill of the Parliament of the United Kingdom that proposes to transpose directly-applicable European Union law into the law of the United Kingdom, as part of the country’s exit from the European Union (Brexit).
 To implement this, the proposed bill will repeal the European Communities Act 1972 which first brought the UK into what became the EU, incorporate all EU law into the UK statute books, and give ministers the power to adapt and remove laws that are no longer relevant.
Transport in Buckinghamshire has been shaped by its position within the United Kingdom.
 Most routes between the UK's two largest cities, London and Birmingham, pass through this county.
 The county's growing industry (such as in Slough) first brought canals to the area, then railways and then motorways.
Sindhology (Sindhi: سنڌولوجي‎ ) is a field of study and academic research that covers the history, society, culture, and literature of Sindh, a province of Pakistan.
 The subject was first brought into the academic circles with the establishment of the Institute of Sindhology at Sindh University in 1964.
 Since then, it has developed into a discipline that covers the aspects of history and archaeology from the Indus Valley Civilization to the modern Sindhi society.
 The subject has also received wider attention at international levels.
 An academic or expert who specialises in Sindhology is called a Sindhologist.
Richard Crispin Armitage (born 22 August 1971) is an English film, television, theatre and voice actor.
 He received notice in the UK with his first leading role as John Thornton in the British television programme "North & South" (2004).
 But it was his role as dwarf prince and leader Thorin Oakenshield in Peter Jackson's film trilogy adaptation of "The Hobbit" that first brought him international recognition.
 Other notable roles include John Proctor in Yaël Farber’s stage production of Arthur Miller's "The Crucible", Francis Dolarhyde in the American TV series "Hannibal", Lucas North in the British TV drama "Spooks", John Porter in the British TV drama "Strike Back", and Guy of Gisborne in the British TV drama "Robin Hood".
 He more recently voiced Trevor Belmont in the Netflix adaptation of "Castlevania".
Connick v. Myers, 461 U.S. 138 (1983), is a United States Supreme Court decision concerning the First Amendment rights of public employees who speak on matters of possible public concern within the workplace context.
 It was first brought by Sheila Myers, an Orleans Parish, Louisiana, assistant district attorney (ADA).
 She had been fired by her superior, District Attorney Harry Connick Sr., when, after receiving a transfer she had fiercely resisted in private conversations with him and his chief assistant district attorney, she distributed a questionnaire to her fellow prosecutors asking about their experience with Connick's management practices.
 At trial, Judge Jack Gordon of the Eastern District of Louisiana found the firing had been motivated by the questionnaire and was thus an infringement on her right to speak out on matters of public concern as a public employee.
 After the Fifth Circuit affirmed the verdict, Connick appealed to the Supreme Court.

 is a two-player character guessing game created by Ora and Theo Coster, also known as Theora Design, that was first manufactured by Milton Bradley, in 1979, now owned by Hasbro.

Omaha hold 'em (also known as Omaha holdem or simply Omaha) is a community card poker game similar to Texas hold 'em, where each player is dealt four cards and must make his or her best hand using exactly two of them, plus exactly three of the five community cards.
 The exact origin of the game is unknown, but casino executive Robert Turner first brought Omaha into a casino setting when he introduced the game to Bill Boyd, who offered it as a game at the Las Vegas Golden Nugget Casino (calling it "Nugget Hold'em").
 Omaha uses a 52-card French deck.
 Limit Omaha hold 'em 8-or-better is the "O" game featured in H.O.R.S.E.
 Both limit Omaha/8 and pot limit Omaha high are featured in the 8-Game.
