The Danes (or Daner) were an olden North Theedish folk living in the nowaday southern Sweden and on the Danish ilands. They were not spoken of by Tacitus, whose nameknown work Theedland speaks of the Gothones (Geats and/or Goths?) and the Suiones (Swedes). They seem to be, however, spoken of by Jordanes, as the Dani, and also by Procopius.
The name Daner is the worbirthlorely root of Dane. Jordanes upkeeps that the Dani were of the same stock as the Suetidi (Swedes, Suithiod?) and drove out the Heruls and took their lands. If Tacitus straightforwardly did not overlook the Dani, and if Jordanes's knowledge was right, it is likely that they first kithed as an offshoot of the Swedes, sometime in the 2nd or 3rd hundredyear A.D. By Sven Aggesen this would have been about the time that Dan the Proud gave his name to the Danes, but that ledger is most likely an untrue tale. The forefather of the kingly house became the forefather of the whole land.
