Gothicism or Gothism (Swedish: Göticism; Latin: Gothicismus) was a cultural movement in Sweden, centered on the belief in the glory of the Swedish Geats, who were identified with the Goths. The founders of the movement were Nicolaus Ragvaldi and the brothers Johannes and Olaus Magnus. The belief continued to hold power in the 17th century, when Sweden was a great power following the Thirty Years' War, but lost most of its sway in the 18th. It was revitalized by Romantic nationalism in the early 19th century, this time with the Vikings as heroic figures.
The name is derived from Jordanes's account of the Gothic urheimat in Scandinavia (Scandza), and the Gothicists in Sweden believed that the Goths had originated from Sweden. The Gothicists took pride in the Gothic tradition that the Ostrogoths and their king Theodoric the Great, who assumed power in the Roman Empire, had Scandinavian ancestry. This pride was expressed as early as the medieval chronicles, where chroniclers wrote about the Goths as the ancestors of the Scandinavians, and the idea was used by Nicolaus Ragvaldi at the Council of Basel to argue that the Swedish monarchy was the foremost in Europe. It also permeated the writings of the Swedish writer Johannes Magnus (Historia de omnibus gothorum sueonumque regibus) and his brother Olaus Magnus (Historia de gentibus septentrionalibus). Both works had a strong influence on contemporary scholarship in Sweden.
