Bructeri

The Bructeri (Greek Βρούκτεροι; but Βουσάκτεροι in Strabo) were a Germanic tribe in Roman imperial times, located in northwestern Germany, in present-day North Rhine-Westphalia. Their territory included both sides of the upper Ems (Latin Amisia) and Lippe (Latin Luppia) rivers. At its greatest extent, their territory apparently stretched between the vicinities of the Rhine in the west and the Teutoburg Forest and Weser river in the east. In late Roman times they moved south to settle upon the east bank of the Rhine facing Cologne, an area later known as the kingdom of the Ripuarian Franks.

The Bructeri formed an alliance with the Cherusci, the Marsi, the Chatti, Sicambri, and the Chauci, under the leadership of Arminius, that defeated the Roman General Varus and annihilated his three legions at the Battle of Teutoburg Forest in 9 AD.

Six years later, one of the generals serving under Germanicus, L. Stertinius defeated the Bructeri near the Ems and devastated their lands. Among the booty captured by Stertinius was the eagle standard of Legio XIX that had been lost at Teutoburg Forest. "The troops were then marched to the furthest frontier of the Bructeri, and all the country between the rivers Amisia and Luppia was ravaged, not far from the forest of Teutoburgium, where the remains of Varus and his legions were said to lie unburied."
