Chariomerus appears only in the Roman History of Cassius Dio.
This would make him the grandnephew of Arminius, the Cherusci leader who defeated the Roman army in Teutonburg Forest in AD 9 but–like Italicus and Italicus's father Flavus–Chariomerus seems to have been a close ally of Rome.
Defeated by the Chatti sometime around AD 88, Chariomerus was deposed by his own people for his Roman ties.
By the end of the 1st century, the Cherusci people had disappeared from treatments of Germany.
