That's true for basically any conflict ever.
For Tacitus (AD 56 – c. 120)(Germania 43, 45, 46), language was a characteristic, but not defining feature of the Germanic peoples.[52] Many of the ascribed ethnic characteristics of the Germani represented them as typically "barbarian", including the possession of stereotypical vices such as "wildness" and of virtues such as chastity.
