Danish slave trade: 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.

Mentuhotep (god's father): 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.
