Anarkali (Urdu: ‎ ; "Anārkalī ") (pomegranate blossom), born as Sharif un-Nissa, and also known as Nadira Begum, was a legendary slave girl.
 It is depicted in the Bollywood movie Mughal-e-Azam that during the Mughal period, she was supposedly ordered to be buried alive between two walls by Mughal emperor Akbar for having an illicit relationship with the Crown-Prince Salim, later to become Emperor Jahangir.
 Due to the lack of evidence and sources, the story of Anarkali is considered by some to be false for the evidence of her grave and body.
 The story of Anarkali is not mentioned in the Akbarnama nor in Tuzuk-e-Jahangiri.
 It was first mentioned by an English tourist and trader William Finch in his journal, who visited India on 24 August 1608.
 The story was originally written by Indian writer Abdul Halim Sharar and on the first page of that book he had clearly mentioned it to be a work of fiction.
 Nevertheless, her story has been adapted into literature, art and cinema.
The Grönegau (also Graingau) is the historic regional name for one of the many Saxon Gaus that have survived to the present day.
 The region was first mentioned in the records in 852.
 The Grönegau is a region that, for the most part, covers the same area as that of the present borough of Melle in the district of Osnabrück in the German state of Lower Saxony.
 From around 800 to the 12th century the old southern Gau border probably ran from Borgholzhausen and Halle to Bünde and Spenge in the east.
 The "Amt" of Grönenberg was first mentioned in 1360.
 Subsequently, it lost parts of the Grönegau of the Early Middle Ages, including Halle, Borgholzhausen and Borgloh.
 From 1852 there are no longer any boundary changes, the extent of the "Amt" of Grönenberg is from this date identical with the later district of Melle and finally, from 1972, the borough of Melle.
 Several societies in the region still carry the name Grönegau.
 Even the motorway services near Melle on the A 30 motorway carry this ancient regional name.
The Easter Cave (German: "Osterhöhle" ) is a small cave in the vicinity of Trondorf (in the municipality of Neukirchen bei Sulzbach-Rosenberg) in Germany.
 The cave is 185 metres long and may be visited during the summer months.
 It was first mentioned in the records around 1630.
 The present entrance was artificially created in 1905 in order to open it as a show cave for visitors.
 The Easter Cave is one of the last caves in Germany to be lit with carbide lamps. Relatively high concentrations of manganese were found on the walls.
 The origin of the German name, "Osterhöhle", is not entirely clear, but it probably comes from the location of the cave on the Osterberg, a hill whose name in turn may possibly be connected with the German goddess of dawn, "Ostara".
The Easter Bilby is an Australian alternative to the Easter Bunny.
Brailo Tezalović (, Latin: "Braylus Thessalovich" ; 1392–1433) was a merchant, nobleman and diplomat, who served Bosnian magnate Pavle Radenović and his family, with the titles of "carinik" (customs official) and "knez" (count).
 Brailo was born into a merchant family from Prača in eastern Bosnia, the son of Mihoje and Vladija, and grandson of Radan.
 He had three younger brothers, Bogiša, Hval, and Vukosav.
 Brailo was first mentioned in a document dated to June 1392, then mentioned in February 1399 as a customs official ("carinik") of count ("knez") Pavle Radenović in Ledenice.
 In the following years he was a diplomat in the service of the Pavlović noble family.
 Brailo Tezalović, Bogdan Muržić and Brajko Hvaonić, all from Prača, were the biggest merchants in Bosnia of their time.
 The main article of commerce was lead, likely mostly from the mine of Olovo.
 The debts of individuals in Bosnia were different and ranged around 100 ducats, but sometimes could cross over 1000 ducats (merchants from Prača reaching the largest individual credits ); Brailo, as the representative of another merchant from Prača (Brajko Hvaonić ), raised the credit to 2965 ducats.
 In 1411, Brailo is mentioned as the "protovestijar" of Pavle for the first time.
 Only in 1413, Brailo sent 11,5 wagons of lead to the Republic of Ragusa.
 He was first mentioned with the title of "knez" on 31 July 1421, and was inscribed as a witness in the charters of the Pavlović in 1427, 1432 and 1433.
 His importance at the Pavlović court is evident from the fact that the Ragusans viewed him as an especially important person in the discussions over the sale of Konavle; when the sale was finalized, Brailo received 500 ducats and a parcel of land from Ragusa.
 He was mentioned as deceased on 28 January 1446.
The Easter Bunny (also called the Easter Rabbit or Easter Hare) is a folkloric figure and symbol of Easter, depicted as a rabbit bringing Easter eggs. Originating among German Lutherans, the "Easter Hare" originally played the role of a judge, evaluating whether children were good or disobedient in behaviour at the start of the season of Eastertide.
 The Easter Bunny is sometimes depicted with clothes.
 In legend, the creature carries colored eggs in his basket, candy, and sometimes also toys to the homes of children, and as such shows similarities to Santa Claus or the Christkind, as they both bring gifts to children on the night before their respective holidays.
 The custom was first mentioned in Georg Franck von Franckenau's "De ovis paschalibus" ('About Easter Eggs') in 1682, referring to a German tradition of an Easter Hare bringing Easter eggs for the children.
The Ordubadi family (also spelled Urdubadi), otherwise known as the Nasiri family, was an Iranian noble-family, which was descended from the medieval philosopher and polymath Nasir al-Din al-Tusi.
 The family was from Ordubad, a town which lay on the banks of the Araxes river, and is first mentioned during the Mongol invasions and conquests.
 The family thereafter disappears from sources, and is first mentioned several decades later when the Safavid dynasty conquered Iran and its surroundings in the 15th-century.
 The leader of the family Bahram Khan Ordubadi, began serving the Safavid king (shah) Ismail I (r. 1501–1524), who appointed him as the civil administrator ("kalantar") of Ordubad.
The Calich was a Ragusan noble family.
 They were first mentioned in the period of 1279–1317.
 In 1377, a "Dobre de Calich" is mentioned.
 In the beginning of the 15th century Ragusan nobility were present in Novo Brdo as merchants or mining lords; Calich were also present.
 In 1457 a "Calice" is mentioned in Novo Brdo.
 They were among the eleven smallest houses in the 15th century.
Wolfartsweier (population approx. 3,500) is a village near Karlsruhe, Baden-Württemberg, Germany.
 It was first mentioned in 1261 AD under the name of "Wolvoldeswilere".
 The local church was first mentioned in 1329.
 A small creek, called Wettersbach, runs through the village, but in an underground canal for most of its way.
 Wolfartsweier has a town hall, a Protestant and a catholic church and community centres, and a public outdoor swimming pool.
Marianus I (died after 18 March 1082) was the Judge of Logudoro from 1073, when he is first mentioned after his father or grandfather, Barisone I, until about 1082, when he is last mentioned.
 His reign is obscure and the next judge mentioned is his son Constantine I in 1112, but to ascribe to Marianus a 39-year reign seems unnecessary and the presence of unknown other judges between Marianus and Constantine is likely.
