Origin
"Little is known about the early history of the Vandals. It has been speculated that the Vandals originated in Scandinavia (in central Sweden, there is a parish called Vendel which may be related), migrated southwards into the region of Silesia, and eventually came into contact with the Romans.
"The first literary reference to this group of people by the Romans can be found in Pliny the Elder’s Natural History. According to this writer, the Vandals, or Vandili, were one of the five groups of Germanic peoples, and consisted of several smaller tribes:
“There are five German races; the Vandili, parts of whom are the Burgundiones, the Varini, the Carini, and the Gutones.”
