The Lugii, Lugi, Lygii, Ligii, Lugiones, Lygians, Ligians, Lugians, or Lougoi were an ancient Germanic tribe  attested in the book Germania by the Roman historian Tacitus. They lived in ca. 400 BC–300 AD in Central Europe, north of the Sudetes mountains in the basin of upper Oder and Vistula rivers, covering most of modern south and middle Poland (regions of Silesia, Greater Poland, Mazovia and Little Poland). Most archaeologists identify the Lugians with the Przeworsk culture. The source of their power was control of the most important middle part of the Amber Road from Sambia at the Baltic Sea to the provinces of Roman Empire: Pannonia, Noricum and Raetia. A tribe of the same name, usually spelled as Lugi, inhabited the southern part of Sutherland in Scotland. Roman records sometimes identify the Lugii with the Vandals, an East Germanic tribe.
