The Lugii (or Lugi, Lygii, Ligii, Lugiones, Lygians, Ligians, Lugians, or Lougoi) were a group of tribes mentioned by Roman authors living in ca.
They played an important role on the middle part of the Amber Road from Sambia at the Baltic Sea to the provinces of Roman Empire: Pannonia, Noricum and Raetia.
According to Tacitus's Annales, in 50 'a great multitude' of Lugians and Hermunduri, led by the Hermundurian Vibilius, took part in the fall of Vannius, who the Romans had imposed as a ruler to replace Maroboduus.
[6] Tacitus however describes the Lugii, writing that they were divided into many tribes ('civitates'), of which he mentions the five most powerful: Harii, Helveconae, Manimi, Helisii and Nahanarvali.
The next information about the Lugians comes from Cassius Dio's work Roman History, in which he mentions events of 91–92 during the reign of emperor Domitian.
Another mention might be a great people of 'Lupiones-Sarmatae' shown on the Latin map Tabula Peutingeriana generally dated to 2nd-4th century AD.
"[3] Herwig Wolfram notes that "In all likelihood the Lugians and the Vandals were one cultic community that lived in the same region of the Oder in Silesia, where it was first under Celtic and then under Germanic domination.
