What is "cherusci"

The Cherusci (sometimes called the Cherusks) were a Germanic tribe that inhabited parts of the plains and forests of northwestern Germany, in the area possibly near present-day Hanover, during the 1st century BC and 1st century AD. Ethnically, Pliny the Elder groups them with their neighbours the Suebi and Chatti, as well as the Hermunduri, as Hermiones, one of the Germanic groupings said to descend from an ancestor named Mannus. They led an important war against the Roman Empire. Subsequently they were probably absorbed into the tribal confederations such as the Franks and Allemanni.
