The Sicambri or Sugambri were a Germanic people who lived in the area between the Rhine, Lippe, and Wupper rivers, in what is now Germany, near the border with the Netherlands. They were first reported by Julius Caesar, who encountered them in 55 BC. They became a significant opponent of Roman imperial power in the Rhine region. After a major defeat by the Romans in 8 BC many of the Sicambri were moved into Roman territory.
