Eder

The Eder [ˈeːdɐ] is a 177-kilometre -long major river in Germany that begins in eastern North Rhine-Westphalia and passes in to Hesse, where it empties into the River Fulda.

The river was first mentioned by the Roman historian Tacitus. In his Annals, he describes the Roman campaign against the Chatti under the command of Germanicus in 15 AD. Forty-five thousand soldiers of the Roman army destroyed the major centre of the Chatti, Mattium, directly after they crossed the Adrana .
