Question: Which relative of Prince Axel of Denmark became king in 1905?
Context: Erik Moltke (4 April 1901 – 19 October 1984) was a runologist, writer, editor.  Through his leadership, the Runologist Section of the National Museum of Denmark became a world centre for the scientific study of runology c.1942 CE. Danish slave trade occurred separately in two different periods.  During the Viking Age, thralls (Norse slaves) were an important part of the economy and one of the main reasons for the raids on England where slaves were captured.  This practice was abolished once Denmark became Christian.  Trading black slaves was part of the transatlantic slave trade by Denmark-Norway around 1671, when the Danish West India Company was chartered, to 1802, when the Dano-Norwegian regent Prince Frederick carried out a ban on the country's participation in the trade.  As of 1778, it was estimated that the Dano-Norwegians shipped about 3,000 Africans to the Danish West Indies annually to be sold as slaves.  The country's ships transported approximately 100,000 enslaved Africans, about 2% of the total number the early 19th century. The National Museum of Denmark's new museum, Brede Works, lies in the countryside just north of Copenhagen in Denmark's largest, protected industrial plants.  At the museum of Industrial culture, the visitors can be guided around by its own virtual person between old machines, hear how Denmark became an industrial society and even try to work at an assembly line.  The exhibitions show the industrial development which has changed the everyday lives of the Danes over the past few centuries. The 2009 UCI ProTour was the fifth series of the UCI ProTour.  Two new teams, the American and the Russian Team Katusha , joined the ProTour, effectively taking over the licenses of Crédit Agricole and Gerolsteiner .  Two existing teams changed title sponsors: Team CSC from Denmark became Team Saxo Bank , and changed name to .  As in 2008, the races organized by the three Grand Tour organizers were not part of the ProTour.  Rather than a ranking based only on the ProTour, the UCI designed a World Calendar, on which the Monument events and Grand Tours were included, with a corresponding 2009 UCI World Ranking. Mentuhotep was the non-royal father of the Ancient Egyptian king Sobekhotep III who ruled for about three years in the Thirteenth Dynasty, around 1750 BC.  Mentuhotep is mainly known from monuments of his son while he was king.  On these monuments appears also his wife Iuhetibu, who was called "king's mother".  On the monuments relating to Sobekhotep III, Mentuhotep bears the title "god's father".  The latter title is often given to non-royal fathers of kings.  Furthermore, from a high number of scarab seals there is known a military official with the title "commander of the ruler's crew".  This official had a son with the same title named Sobekhotep.  It seems possible that these scarabs belong to the "god's father" Mentuhotep before his son became king.  It is not known under which circumstances Sobekhotep III became king.  However, his father Mentuhotep had no known royal connections.  Two further sons are known, Seneb and Khakau.  They were bearing the title "king's son", albeit being evidently not the son of a king, but brothers of one.

The Guldborgsund bridge (Danish: "Guldborgbroen" ) spans the northern end of the Guldborgsund, between the islands of Lolland and Falster in Denmark.  The bridge consists of two steel arched spans with a 30m central opening section having two rising bascules.

Fastelavn is the name for Carnival in the historically Lutheran nations of Denmark, Norway, Greenland, Estonia and the Faroe Islands which is either the Sunday or Monday before Ash Wednesday.  Fastelavn is related to Roman Catholic tradition of Carnival in the days before Lent, but after Denmark became a Protestant nation, the festival adopted certain distinctives.  This holiday occurs the week before the Christian penitential season of Lent, culminating on Shrove Tuesday, the day before Ash Wednesday, the first day of Lent.  In it, children dress up in costumes and gathering treats for the "Fastelavn" feast.  The holiday is generally considered to be a time for children's fun and family games.
