Getae and Dacians? Are they the same? Or is this unknowable?

Well, about that names, just see another comparation. Germans are called by most of the peoples "Germans", but they call themselves "Deutsch".

I see where you are heading, but your example is wrong. 'German' is the English word, but the Dutch use 'Duits' and Italians use 'tedesco'.
On the other hand, the French use 'Allemand', Spanish use 'alemán', Portugese use 'alemão', and so on.

Well, wasnt Romans who call them "German" first ? Anyway, my point is that first authors who write about them, from Greek origin, call them Getae, the same as Romans call the Deutsch "German", and later the name Daci prevaled, being used by both Dacians and Romans, even if the name Getae doesnt totally dissapear. Its not sure from where this name show up, but for sure Getae and Dacians was the same peoples, even if some said that regional groups of one and the same peoples.
