Ostrogoths
Ostrogoths are the bright shiny Goths. Original homeland somewhere around the Baltic Sea, then eastern Europe, then Italy and Yugoslavia.
Good horse archers and spearmen.
They set up a kingdom in Italy following the fall of the Western Roman Empire and seem to have gotten along ok with the indigenous Romans. They kept Roman administrative systems in place for the most part.
Did not do so well against the Eastern Roman Empire. Justinian sent Belisarius to reconquer Italy, leaving much devastation and everyone too weak to resist the Lombards when they invaded.
