 According to an old proposal, in the 2nd century AD, eastern Germanic peoples then mainly in the area of modern Poland, began to expand their influence, pressing peoples to their south and eventually causing the Marcomannic Wars on the Roman Danubian frontier.The Rugii are one of the peoples thought to have been involved.While modern authors are sceptical of some elements of the old narrative, the archaeology of the Wielbark culture has given new evidence to support this idea.
